Docker CLI does not directly support +replication. HPE 3PAR Storage Plugin extends Docker's "volume create" +command interface via optional parameter in order to make it possible. + +HPE 3PAR Storage Plugin assumes that an already working 3PAR Remote +Copy setup is present. The plugin has to be configured with the +details of this setup in a configuration file called hpe.conf. + +On the 3PAR front, core to the idea of replication is the concept of +remote copy group (RCG) that aggregates all the volumes that need to +be replicated simultaneously to a remote site. + +HPE 3PAR Storage Plugin extends Docker's "volume create" command via +optional parameter 'replicationGroup'. This represents the name of the +RCG on 3PAR which may or may not exist. In the former case, it gets +created and the new volume is added to it. In the latter case, the +newly created volume is added to the existing RCG. + +'replicationGroup' flag is effective only if the backend in +the configuration file hpe.conf has been configured as a +replication-enabled backend. Multiple backends with different +permutations and combinations can be configured. + +**Note:** + +1.

With only QOS 2. With only flash-cache 3. With both 4. Without both i.e. just a VVSet with the source volume member of it * File Persona Support This is work in progress So far implemented: * CRD operations * Share state management TODO: * Rollback requires some work * Testing of some scenarios * File Persona: using single configuration file Implemented the following: ================== 1. Dependency on common configuration file between block and file protocols 2. Adding of client IP access via WSAPI call TODOs: ===== 1. Unit test implementation to adapt to share creation on child thread. Presently it fails. 2. Rollback 3. Quota size 4. Testing of some scenarios * Fixed typo in function name * Fixed PEP8 issues * Commented out fix for issue #428 for now * Fixed UT failures Due to changes to the design, block UTs were failing. Fixed those. * Fixed couple of more PEP8 issues * Added code for multiple default backends * Expect cpg to be list type in hpe.conf In block, cpg is a list type in hpe.conf. File earlier used expect cpg to be string type.

Docker CLI does not directly support +replication. HPE 3PAR Storage Plugin extends Docker's "volume create" +command interface via optional parameter in order to make it possible. + +HPE 3PAR Storage Plugin assumes that an already working 3PAR Remote +Copy setup is present. The plugin has to be configured with the +details of this setup in a configuration file called hpe.conf. + +On the 3PAR front, core to the idea of replication is the concept of +remote copy group (RCG) that aggregates all the volumes that need to +be replicated simultaneously to a remote site. + +HPE 3PAR Storage Plugin extends Docker's "volume create" command via +optional parameter 'replicationGroup'. This represents the name of the +RCG on 3PAR which may or may not exist. In the former case, it gets +created and the new volume is added to it. In the latter case, the +newly created volume is added to the existing RCG. + +'replicationGroup' flag is effective only if the backend in +the configuration file hpe.conf has been configured as a +replication-enabled backend. Multiple backends with different +permutations and combinations can be configured. + +**Note:** + +1. For a replication-enabled backend, it is mandatory to specify +'replicationGroup' option while creating replicated volume. +2. User cannot create non-replicated/standard volume(s) using +replication-enabled backend. In order to do so, user would need to +define another backend in hpe.conf with similar details as that of +replication-enabled backend except that "replication_device" field is +omitted. +3. For a backend that is NOT replication-enabled, specifying 'replicationGroup' +is incorrect and results in error. +4. For a given RCG, mixed transport protocol is not supported. E.g. volumes v1, v2 and v3 + are part of RCG called TestRCG, then on primary array, if these volumes are exported via + FC protocol then on secondary array those CANNOT be exported via ISCSI (after failover) + and vice versa. +5.

With only QOS 2. With only flash-cache 3. With both 4. Without both i.e. just a VVSet with the source volume member of it * File Persona Support This is work in progress So far implemented: * CRD operations * Share state management TODO: * Rollback requires some work * Testing of some scenarios * File Persona: using single configuration file Implemented the following: ================== 1. Dependency on common configuration file between block and file protocols 2. Adding of client IP access via WSAPI call TODOs: ===== 1. Unit test implementation to adapt to share creation on child thread. Presently it fails. 2. Rollback 3. Quota size 4. Testing of some scenarios * Fixed typo in function name * Fixed PEP8 issues * Commented out fix for issue #428 for now * Fixed UT failures Due to changes to the design, block UTs were failing. Fixed those. * Fixed couple of more PEP8 issues * Added code for multiple default backends * Expect cpg to be list type in hpe.conf In block, cpg is a list type in hpe.conf. File earlier used expect cpg to be string type. After common configuration file, File needed this change * Fixed broken Travis CI * Fixed unit test related to listing of volumes *Cannot rely on first manager anymore as user may or may not configure both the managers. * Fixed multiple issues Implemented following: 1. IP range 2. Delete FPG with last share delete 3. Renamed "persona" flag to "filePersona" 4. Fixed mount/unmount 5. Fixed default share size 6. Lock by share name 7. In share meta-data, IP/Subnet were not getting updated for second share onwards * Update file_backend_orchestrator.py Added one missing paramter * Fixed mount/unmount + Addressed review comment * Mount infomration needed to be stored as a dictionary with mount_id as key and mount_dir as value * If default FPG dict is empty, needed to throw exception EtcdDefaultFpgNotPresent * Removed replication related code * Update file_manager.py Fixed couple of PEP8 issues * Update hpe_3par_mediator.py Fixed the configuration parameter names * Review Comments addressed * Unit test framework fixed for decrypt_password * Rollback for default share creation TODO: * Rollback for non-default share creation * Resolved PEP8 errors * Fixed async initialization failure in UTs * Update cmd_deleteshare.py Fixed typo * Update cmd_deleteshare.py Fixed typo * Added logging * Backend metadata initialization done for a use case * PEP8 fixed + Quota set in a use case * Combined default and non-default share creation into one template function create_share_on_fpg() can now create both default and non-default shares. It achieves this by using specific implementations of two functions the references of which are passed to it as argument. Rest of the function steps are common to both default and non-default share creation process. * Removed unused import references * Async initialization fix * Added sleep to main UT thread * Fixed PEP8 * Default size modified + share create on legacy FPG issue fixed *Changed default FPG to 16TiB and default share size to 1TiB *Fixed share creation issue on legacy FPG * Updated error message for legacy FPG use case --- hpedockerplugin/backend_async_initializer.py | 8 +- hpedockerplugin/backend_orchestrator.py | 6 +- hpedockerplugin/cmd/cmd_createfpg.py | 5 +- hpedockerplugin/cmd/cmd_createshare.py | 21 +-- hpedockerplugin/cmd/cmd_deleteshare.py | 10 +- hpedockerplugin/cmd/cmd_initshare.py | 26 +-- hpedockerplugin/file_manager.py | 160 +++++++++++-------- hpedockerplugin/hpe/hpe_3par_iscsi.py | 2 +- hpedockerplugin/hpe/hpe_3par_mediator.py | 4 +- hpedockerplugin/hpe_storage_api.py | 2 +- hpedockerplugin/request_context.py | 4 +- hpedockerplugin/volume_manager.py | 4 +- test/hpe_docker_unit_test.py | 28 ++-- 13 files changed, 156 insertions(+), 124 deletions(-) diff --git a/hpedockerplugin/backend_async_initializer.py b/hpedockerplugin/backend_async_initializer.py index b0e2fc23..be1d46a8 100644 --- a/hpedockerplugin/backend_async_initializer.py +++ b/hpedockerplugin/backend_async_initializer.py @@ -19,6 +19,7 @@ """ +import six import threading from oslo_log import log as logging @@ -58,8 +59,9 @@ def run(self): except Exception as ex: volume_mgr['mgr'] = None volume_mgr['backend_state'] = 'FAILED' - LOG.error('INITIALIZING backend: %s FAILED Error: %s' - % (self.backend_name, ex)) + LOG.error('CHILD-THREAD: INITIALIZING backend: %s FAILED Error:' + '%s' % (self.backend_name, six.text_type(ex))) finally: - LOG.info('in finally : %s , %s ' % (self.backend_name, volume_mgr)) + LOG.info('in finally : %s , %s ' % (self.backend_name, + volume_mgr)) self.manager_objs[self.backend_name] = volume_mgr diff --git a/hpedockerplugin/backend_orchestrator.py b/hpedockerplugin/backend_orchestrator.py index 4c75bb9d..23d0bfb8 100644 --- a/hpedockerplugin/backend_orchestrator.py +++ b/hpedockerplugin/backend_orchestrator.py @@ -29,6 +29,7 @@ import json from oslo_log import log as logging import os +import six import uuid import hpedockerplugin.volume_manager as mgr import hpedockerplugin.etcdutil as util @@ -102,8 +103,9 @@ def initialize_manager_objects(self, host_config, backend_configs): thread.start() except Exception as ex: - LOG.error('INITIALIZING backend: %s FAILED Error: %s' - % (backend_name, ex)) + LOG.error('MAIN-THREAD: INITIALIZING backend: %s FAILED ' + 'Error: %s' + % (backend_name, six.text_type(ex))) LOG.info("Backends INITIALIZED => %s" % manager_objs.keys()) diff --git a/hpedockerplugin/cmd/cmd_createfpg.py b/hpedockerplugin/cmd/cmd_createfpg.py index 189ee3d0..12766a35 100644 --- a/hpedockerplugin/cmd/cmd_createfpg.py +++ b/hpedockerplugin/cmd/cmd_createfpg.py @@ -6,7 +6,7 @@ LOG = logging.getLogger(__name__) -FPG_SIZE = 64 +FPG_SIZE = 16 class CreateFpgCmd(cmd.Cmd): @@ -32,7 +32,8 @@ def execute(self): fpg_metadata = { 'fpg': self._fpg_name, 'fpg_size': FPG_SIZE, - 'reached_full_capacity': False + 'reached_full_capacity': False, + 'docker_managed': True } self._fp_etcd.save_fpg_metadata(self._backend, self._cpg_name, diff --git a/hpedockerplugin/cmd/cmd_createshare.py b/hpedockerplugin/cmd/cmd_createshare.py index 87305bb0..6ba2a678 100644 --- a/hpedockerplugin/cmd/cmd_createshare.py +++ b/hpedockerplugin/cmd/cmd_createshare.py @@ -71,7 +71,9 @@ def _create_share(self): self._status = 'AVAILABLE' self._share_args['status'] = self._status share_etcd.save_share(self._share_args) - self._increment_share_cnt_for_fpg() + # Increment count only if it is Docker managed FPG + if self._share_args.get('docker_managed'): + self._increment_share_cnt_for_fpg() except Exception as ex: msg = "Share creation failed [share_name: %s, error: %s" %\ (share_name, six.text_type(ex)) @@ -293,23 +295,6 @@ def execute(self): vfs_name = vfs_info['name'] ip_info = vfs_info['IPInfo'][0] - # fpg_metadata = { - # 'fpg': fpg_name, - # 'fpg_size': fpg_info['capacityGiB'], - # 'vfs': vfs_name, - # 'ips': {ip_info['netmask']: [ip_info['IPAddr']]}, - # 'reached_full_capacity': False - # } - # LOG.info("Creating FPG entry in ETCD for legacy FPG: " - # "%s" % six.text_type(fpg_metadata)) - # - # # TODO: Consider NOT maintaing FPG information in - # # ETCD.

Rest of the function steps are common to both default and non-default share creation process. * Removed unused import references * Async initialization fix * Added sleep to main UT thread * Fixed PEP8 * Default size modified + share create on legacy FPG issue fixed *Changed default FPG to 16TiB and default share size to 1TiB *Fixed share creation issue on legacy FPG * Updated error message for legacy FPG use case * Updated help content for File Persona * FPG initialization requires share_cnt initialization * Default FPG name conflict fix + Default FPG size fix * Removed unused variable to fix PEP8 error * Added range check for default FPG size --- hpedockerplugin/cmd/cmd_createfpg.py | 14 +++- .../cmd/cmd_generate_fpg_vfs_names.py | 11 ++- hpedockerplugin/exception.py | 8 ++ hpedockerplugin/file_manager.py | 81 +++++++++++++------ hpedockerplugin/hpe/hpe3par_opts.py | 7 +- hpedockerplugin/hpe/hpe_3par_mediator.py | 40 +++++++-- hpedockerplugin/request_context.py | 5 +- 7 files changed, 125 insertions(+), 41 deletions(-) diff --git a/hpedockerplugin/cmd/cmd_createfpg.py b/hpedockerplugin/cmd/cmd_createfpg.py index 2a63edca..80be8ecf 100644 --- a/hpedockerplugin/cmd/cmd_createfpg.py +++ b/hpedockerplugin/cmd/cmd_createfpg.py @@ -25,13 +25,23 @@ def execute(self): LOG.info("Creating FPG %s on the backend using CPG %s" % (self._fpg_name, self._cpg_name)) try: - self._mediator.create_fpg(self._cpg_name, self._fpg_name) + config = self._file_mgr.get_config() + fpg_size = FPG_SIZE + if config.hpe3par_default_fpg_size: + fpg_size = int(config.hpe3par_default_fpg_size) + LOG.info("Default FPG size overridden to %s" % fpg_size) + + self._mediator.create_fpg( + self._cpg_name, + self._fpg_name, + fpg_size + ) if self._set_default_fpg: self._old_fpg_name = self._set_as_default_fpg() fpg_metadata = { 'fpg': self._fpg_name, - 'fpg_size': FPG_SIZE, + 'fpg_size': fpg_size, 'share_cnt': 0, 'reached_full_capacity': False, 'docker_managed': True diff --git a/hpedockerplugin/cmd/cmd_generate_fpg_vfs_names.py b/hpedockerplugin/cmd/cmd_generate_fpg_vfs_names.py index 434357af..5a987921 100644 --- a/hpedockerplugin/cmd/cmd_generate_fpg_vfs_names.py +++ b/hpedockerplugin/cmd/cmd_generate_fpg_vfs_names.py @@ -21,12 +21,17 @@ def _generate_default_fpg_vfs_names(self): try: backend_metadata = self._fp_etcd.get_backend_metadata( self._backend) - counter = backend_metadata['counter'] + 1 + counter = int(backend_metadata.get('counter', 0)) + 1 backend_metadata['counter'] = counter new_fpg_name = "DockerFpg_%s" % counter new_vfs_name = "DockerVfs_%s" % counter - default_fpgs = backend_metadata['default_fpgs'] - default_fpgs.update({self._cpg_name: new_fpg_name}) + default_fpgs = backend_metadata.get('default_fpgs') + if default_fpgs: + default_fpgs.update({self._cpg_name: new_fpg_name}) + else: + backend_metadata['default_fpgs'] = { + self._cpg_name: new_fpg_name + } # Save updated backend_metadata self._fp_etcd.save_backend_metadata(self._backend, diff --git a/hpedockerplugin/exception.py b/hpedockerplugin/exception.py index c87ca148..382c5f82 100644 --- a/hpedockerplugin/exception.py +++ b/hpedockerplugin/exception.py @@ -418,5 +418,13 @@ class FpgCreationFailed(PluginException): message = _("FPG creation failed: %(reason)s") +class FpgAlreadyExists(PluginException): + message = _("FPG already exists: %(reason)s") + + class SetQuotaFailed(PluginException): message = _("Set quota failed: %(reason)s") + + +class HPEDriverNonExistentCpg(HPEDriverException): + message = "CPG %(cpg)s does not exist" diff --git a/hpedockerplugin/file_manager.py b/hpedockerplugin/file_manager.py index d1443235..8fc370e0 100644 --- a/hpedockerplugin/file_manager.py +++ b/hpedockerplugin/file_manager.py @@ -81,6 +81,13 @@ def get_config(self): def _initialize_configuration(self): self.src_bkend_config = self._get_src_bkend_config() + def_fpg_size = self.src_bkend_config.hpe3par_default_fpg_size + if def_fpg_size: + if def_fpg_size < 1 or def_fpg_size > 64: + msg = "Configured hpe3par_default_fpg_size MUST be in the " \ + "range 1 and 64.

With only QOS 2. With only flash-cache 3. With both 4. Without both i.e. just a VVSet with the source volume member of it * File Persona Support This is work in progress So far implemented: * CRD operations * Share state management TODO: * Rollback requires some work * Testing of some scenarios * File Persona: using single configuration file Implemented the following: ================== 1. Dependency on common configuration file between block and file protocols 2. Adding of client IP access via WSAPI call TODOs: ===== 1. Unit test implementation to adapt to share creation on child thread. Presently it fails. 2. Rollback 3. Quota size 4. Testing of some scenarios * Fixed typo in function name * Fixed PEP8 issues * Commented out fix for issue #428 for now * Fixed UT failures Due to changes to the design, block UTs were failing. Fixed those. * Fixed couple of more PEP8 issues * Added code for multiple default backends * Expect cpg to be list type in hpe.conf In block, cpg is a list type in hpe.conf. File earlier used expect cpg to be string type. After common configuration file, File needed this change * Fixed broken Travis CI * Fixed unit test related to listing of volumes *Cannot rely on first manager anymore as user may or may not configure both the managers. * Fixed multiple issues Implemented following: 1. IP range 2. Delete FPG with last share delete 3. Renamed "persona" flag to "filePersona" 4. Fixed mount/unmount 5. Fixed default share size 6. Lock by share name 7. In share meta-data, IP/Subnet were not getting updated for second share onwards * Update file_backend_orchestrator.py Added one missing paramter * Fixed mount/unmount + Addressed review comment * Mount infomration needed to be stored as a dictionary with mount_id as key and mount_dir as value * If default FPG dict is empty, needed to throw exception EtcdDefaultFpgNotPresent * Removed replication related code * Update file_manager.py Fixed couple of PEP8 issues * Update hpe_3par_mediator.py Fixed the configuration parameter names * Review Comments addressed * Unit test framework fixed for decrypt_password * Rollback for default share creation TODO: * Rollback for non-default share creation * Resolved PEP8 errors * Fixed async initialization failure in UTs * Update cmd_deleteshare.py Fixed typo * Update cmd_deleteshare.py Fixed typo * Added logging * Backend metadata initialization done for a use case * PEP8 fixed + Quota set in a use case * Combined default and non-default share creation into one template function create_share_on_fpg() can now create both default and non-default shares. It achieves this by using specific implementations of two functions the references of which are passed to it as argument. Rest of the function steps are common to both default and non-default share creation process. * Removed unused import references * Async initialization fix * Added sleep to main UT thread * Fixed PEP8 * Default size modified + share create on legacy FPG issue fixed *Changed default FPG to 16TiB and default share size to 1TiB *Fixed share creation issue on legacy FPG * Updated error message for legacy FPG use case * Updated help content for File Persona * FPG initialization requires share_cnt initialization * Fix for issue #607 * Fixed issues #600, #606, #607 * Fixed pep8 * Overridden WS minimum version check to 3.3.1 * Disabled 'readonly', 'nfsOptions' and 'comment' options These options if required can be exposed in the future. For now there is no need to expose these. * Disabled 'readonly', 'nfsOptions' and 'comment' options These options can be added back if needed in the future. For now, removing them. * Fix for issue #620 Race condition was occurring between backend initialization threads as regards to fp_etcd_client. Moved its creation main thread to avoid it. * Fixed issue #620 fp_etcd_client could not be initialized in the FileBackendOrchestrator constructor as it was being accessed even before constructor would get invoked. Hence created a static method which is getting invoked from the base class to create fp_etcd_client even before it is used * Adding back as the code got removed inadvertently * Removed unused import to fix PEP8 * Fixed #609 to return relevant share details for inspect * Treat DEFAULT_BLOCK and DEFAULT_FILE as special keywords always * Allow mount only if share is in 'AVAILABLE' state * Disallow remove if share mounted + PEP8 --- hpedockerplugin/backend_orchestrator.py | 5 + hpedockerplugin/cmd/cmd_createfpg.py | 88 ++- hpedockerplugin/cmd/cmd_createshare.py | 217 +------ hpedockerplugin/cmd/cmd_deleteshare.py | 76 ++- .../cmd/cmd_generate_fpg_vfs_names.py | 13 +- hpedockerplugin/file_backend_orchestrator.py | 17 +- hpedockerplugin/file_manager.py | 345 +++++++---- hpedockerplugin/hpe/hpe_3par_mediator.py | 556 ++---------------- hpedockerplugin/hpe/share.py | 4 +- hpedockerplugin/hpe_storage_api.py | 20 +- hpedockerplugin/request_context.py | 15 +- 11 files changed, 481 insertions(+), 875 deletions(-) diff --git a/hpedockerplugin/backend_orchestrator.py b/hpedockerplugin/backend_orchestrator.py index 23d0bfb8..64600975 100644 --- a/hpedockerplugin/backend_orchestrator.py +++ b/hpedockerplugin/backend_orchestrator.py @@ -46,6 +46,7 @@ def __init__(self, host_config, backend_configs, def_backend_name): LOG.info('calling initialize manager objs') self._def_backend_name = def_backend_name self._etcd_client = self._get_etcd_client(host_config) + self._initialize_orchestrator(host_config) self._manager = self.initialize_manager_objects(host_config, backend_configs) @@ -54,6 +55,10 @@ def __init__(self, host_config, backend_configs, def_backend_name): self.volume_backends_map = {} self.volume_backend_lock = threading.Lock() + @staticmethod + def _initialize_orchestrator(host_config): + pass + def get_default_backend_name(self): return self._def_backend_name diff --git a/hpedockerplugin/cmd/cmd_createfpg.py b/hpedockerplugin/cmd/cmd_createfpg.py index 80be8ecf..40d776bf 100644 --- a/hpedockerplugin/cmd/cmd_createfpg.py +++ b/hpedockerplugin/cmd/cmd_createfpg.py @@ -18,6 +18,9 @@ def __init__(self, file_mgr, cpg_name, fpg_name, set_default_fpg=False): self._cpg_name = cpg_name self._fpg_name = fpg_name self._set_default_fpg = set_default_fpg + self._backend_fpg_created = False + self._default_set = False + self._fpg_metadata_saved = False def execute(self): with self._fp_etcd.get_fpg_lock(self._backend, self._cpg_name, @@ -36,8 +39,11 @@ def execute(self): self._fpg_name, fpg_size ) + self._backend_fpg_created = True + if self._set_default_fpg: - self._old_fpg_name = self._set_as_default_fpg() + self._add_to_default_fpg() + self._default_set = True fpg_metadata = { 'fpg': self._fpg_name, @@ -50,7 +56,7 @@ def execute(self): self._cpg_name, self._fpg_name, fpg_metadata) - + self._fpg_metadata_saved = True except (exception.ShareBackendException, exception.EtcdMetadataNotFound) as ex: msg = "Create new FPG %s failed.
