However, it is recommended that you only create file-operation rules if the files you intend to replicate are predictably similar in size and not especially large. This procedure is available only through the command-line interface (CLI). You can also specify the number of workers that are spawned by a replication policy to limit the amount of cluster resources that are consumed. SyncIQ also deletes reports after the number of reports exceeds the specified limit. Failover reversion undoes a failover operation on a secondary cluster, enabling you to replicate data from the primary cluster to the secondary cluster again. You might want to migrate SmartLock directories if you restored the directories on a target cluster, and want to transfer those directories either back to the source cluster or to a new cluster. If you want to free the space before files are released from a WORM state, contact Isilon Technical Support for information about reformatting your cluster. After you reset a replication policy, you must perform either a full or differential replication. car-. Specifies the directory on the local cluster that files are replicated from. Cancel Selection from the Sorts output by the type of replication policy. Displays information about a completed replication job that targeted the local cluster. --source-include-directories is specified, If you specify this option, you must also specify To ensure that all files are retained for the appropriate time period, you can commit all files in target SmartLock directories to a WORM state. /ifs/data/media/music/working directory does have an effect, because the directory would be replicated if the setting was not specified. SyncIQ generates replication jobs according to replication policies. Replicate data to the target cluster by running the policies you created. If set to Support Us By Shopping Your Own Favorite Products https://amzn.to/326qvbF This Video is a brief introduction on command line for isilon OneFs 7 … If one or more directories are specified by this setting, any directories that are not specified are not replicated. Prompts you to specify a password for the target cluster after the command is run. If a disaster occurs an hour after a replication job begins, the RPO is four hours, because it has been four hours since a completed job began replicating data. Run jobs automatically according to a schedule. The following values are valid: Creates a performance rule that limits the number of files that can be sent by replication jobs per second. 0. From the If a replication job remains paused for more than a week, SyncIQ automatically cancels the job. The number of nanoseconds past the mtime that the item was last modified. The following command configures SyncIQ to delete replication reports that are older than 2 years: SyncIQ does not support dynamically allocated IP address pools. Also, all previously created replication policies are disabled. SyncIQ domains can be assigned to source and target directories of replication policies. It is recommended that you specify file-criteria statements in a replication policy only if necessary. Selects files based on whether they are owned by the user of the specified name. This option is valid only if the last replication job completed successfully or if you are performing a full or differential replication. You can configure any number of file-criteria definitions. Replication reports are routinely deleted by SyncIQ after the expiration date for the reports has passed. Looking for a version 8 command. --target-compare-initial-sync option. Matches any character in place of the question mark. Displays subreports about the specified policy. However, you can configure how long archival snapshots are retained on the target cluster. Deletes files in the target directory if they are no longer present on the source. when-source-modified causes OneFS to replicate data every time that the source directory of the policy is modified. bat but not in the following format: To configure a policy to be run only manually, specify the following option: Specifies whether to perform a checksum on each file data packet that is affected by the SyncIQ job. Forcing a target break might cause errors if an associated replication job is currently running. This option will affect only policies that specify the target cluster as a SmartConnect zone. This can be useful if, for example, your source cluster is being used for production purposes and your target cluster is being used only for archiving. You can configure a replication policy to exclude files that meet or do not meet specific criteria. You can exclude directories from being replicated by replication policies even if the directories exist under the specified source directory. isi sync target allow_write command is most commonly used in failover and failback operations. Before running a replication job, SyncIQ creates a snapshot of the source directory. If you both include and exclude directories, any excluded directories must be contained in one of the included directories; otherwise, the excluded-directory setting has no effect. Displays any report-related actions that you can perform. SyncIQ does not account for excluded files or directories when detecting changes, so policies that exclude files or directories from replication might be run unnecessarily. Once SyncIQ has been enabled by the cluster admin, a global encryption flag is automatically set, requiring all SyncIQ policies to be encrypted. For example, the following command automatically commits all files in. If you cannot resolve the issue that caused the error, you can reset the replication policy. The Breaking a policy association causes either a full replication or differential replication to occur the next time you run the replication policy. If SyncIQ is permanently unable to communicate with the target cluster, specify the For example, Displays information about a running replication job. If a replication job connects to a dynamically allocated IP address, SmartConnect might reassign the address while a replication job is running, which would disconnect the job and cause it to fail. If a file or sub-directory is deleted from the source directory, the file or directory is deleted from the target cluster when the policy is run again. You can use synchronization policies to fail over and fail back data between source and target clusters. If you believe you have fixed the error, you can return the replication policy to an enabled state by resolving the policy. After a 3 hour Webex session, the engineer pointed to KB 334043. By default, all files and directories under the source directory of a replication policy are replicated to the target cluster. /ifs directory. For example, the following command cancels a replication job created according to weeklySync: To cancel all jobs targeting the local cluster, run the following command: The fully qualified domain name of any node in the target cluster. If this option is not specified, archival snapshots will remain indefinitely on the target cluster. Isilon clusters support IEEE Std 1003.2 (POSIX.2) regular expressions. For the purposes of explaining failover and failback procedures, the cluster originally accessed by clients is referred to as the primary cluster, and the cluster that client data is originally replicated to is referred to as the secondary cluster. Displays information about a replication job created according to the specified replication policy. SyncIQ generates target snapshots to facilitate failover on the target cluster regardless of whether a SnapshotIQ license has been configured on the target cluster. isi sync target list command. Displays information about the specified replication policy. Complete the following procedure for each SmartLock directory that you want to recover. This option is available for copy policies only. --source-subnet. You can include multiple days by specifying multiple values separated by commas. Modifies the replication performance rule of the specified ID. However, the setting that excludes the Because autocommit information is not transferred to the target cluster, files that were scheduled to be committed to a WORM state on the source cluster will not be scheduled to be committed at the same time on the target cluster. Scheduling a policy can be useful under the following conditions: Configuring a policy to start when changes are made to the source directory can be useful under the following conditions: For policies that are configured to start whenever changes are made to the source directory, SyncIQ checks the source directories every ten seconds. Complete the following procedure for each replication policy that you want to fail over: After you fail over to a secondary cluster, you can fail back to the primary cluster. Run the policy only on nodes in the specified subnet and pool. Deleting files on the source cluster improves performance on the source cluster while maintaining the deleted files on the target cluster. The source directory is not a SmartLock directory. SyncIQ creates and references snapshots to replicate a consistent point-in-time image of a root directory. If SyncIQ is unable to communicate with the target cluster, you must specify this option to successfully delete the policy. Specifying Isilon SyncIQ Commvault extends the management of snapshots with Isilon to include the ability to perform “Offline Replication of Snapshots”, which is a method to copy snapshots from one Isilon cluster to another using the SyncIQ replication software module available in OneFS. A paused job reserves cluster resources whether or not the resources are in use. If you delete a replication policy, SyncIQ automatically deletes any reports that were generated for that policy. To perform a full replication, disable the Displays a message confirming that the snapshot schedule was created. Differential replication can be much faster than a full replication if there is an adequate amount of available CPU for the differential replication job to consume. # isi sync jobs start –test Although you cannot fail over or fail back SmartLock directories, you can recover SmartLock directories on a target cluster. If you modify any of the following policy settings after the policy is run, OneFS performs either a full or differential replication the next time the policy is run: This applies only if you target a different cluster. If more than five replication jobs exist on a cluster, the first five jobs run while the others are queued to run. The time when data about the policy or job was last collected from the source cluster. The following wildcard characters are accepted: For example, No more than five running and paused replication jobs can exist on a cluster at a time. If a disaster occurs while a replication job is running, the data on the secondary cluster is reverted to the state it was in when the last replication job completed. The following job statuses are possible: The job is currently running without error. SyncIQ generates one repstate file for each replication job. Displays information about a replication policy that is targeting the local cluster. However, data that was previously replicated to the local cluster is still available. Changes to the configuration of the target cluster outside of SyncIQ can introduce an error condition that effectively breaks the association between the source and target cluster. You can interrupt replication jobs that target the local cluster. For example, However, you can configure how long archival snapshots are retained on the target cluster. SyncIQ generates source snapshots to ensure that replication jobs do not transfer unmodified data. Displays a list of replication performance rules. Sorts output by the path of the source directory. The POSIX timestamp of when the item was last accessed. car-. If necessary, you can log in to a node through the command-line interface and view the contents of the When a job is created for a replication policy, SyncIQ checks whether it is the first job created for the policy. If the job is then restarted, SyncIQ creates another subreport about the progress of the job until the job either completes or is interrupted again. The following command creates a SyncIQ domain for. Includes or excludes files based on their size. Reverting a failover operation does not migrate modified data back to the primary cluster. You can create two types of replication policies: synchronization policies and copy policies. You can also reduce resource consumption through file-operation rules that limit the rate at which replication policies are allowed to send files. File sizes are represented in multiples of 1024, not 1000. Displays information about a completed replication job that targeted a remote cluster. For example, consider a replication policy that synchronizes You can then run the policy again to test whether the issue was fixed. [ ]. You can then fail back to a primary cluster if the primary cluster becomes available again. The ID of the ChangelistCreate job that created the changelist. The POSIX timestamp of when the item was last changed. Failback is the process that allows clients to access data on the primary cluster again and begins to replicate data back to the secondary cluster. Run the policy on all nodes in this cluster. We're here to help. Cancelling a replication job stops data from being replicated and frees the cluster resources that were replicating data. Sorts output by the name of the replication policy. To create a changelist, you must have access to two consecutive snapshots and an associated repstate generated by a replication policy. 2-Way NDMP (Local): Tape media is local or directly connected to the Isilon cluster, so backup or restore data flows between the Isilon cluster and local tape media over FC, though catalog data flows from the Isilon cluster to the DMA over Ethernet. OneFS generates no more than 40 workers for a replication job. This predicate is valid only for copy policies. isi sync jobs start command with the
You need to run the command “isi devices” on the node with the suspect drive to determine what bay the drive is actually in. To cancel a job, specify a replication policy. When a source cluster becomes unavailable, you can fail over data on a target cluster and make the data available to clients. You can modify, view, enable and disable replication policies. SyncIQ then replicates data according to the snapshot rather than the current state of the cluster, allowing users to modify source-directory files while ensuring that an exact point-in-time image of the source directory is replicated. However, a full replication is less strenuous on CPU usage than a differential replication. If you delete a replication policy, SyncIQ automatically deletes any reports that were generated for that policy. Displays a sub report about the specified replication job. Displays information about running replication jobs targeting the local cluster. You can view information about replication jobs that are currently running or paused. Specifies the snapshot naming pattern for snapshots that are generated by replication jobs on the target cluster. Specifies a new name for this replication policy. SyncIQ creates a mirror policy for each replication policy on the secondary cluster. Resetting a policy causes OneFS to perform a full or differential replication the next time the policy is run. However, if the action of the replication policy is set to copy, any file that was deleted on the primary cluster will be present on the secondary cluster. The POSIX timestamp of when the item was last modified. The number of nanoseconds past the atime that the item was last accessed. 162, and After a job for the policy completes successfully, SyncIQ will resume checking the source directory every ten seconds. The number of nanoseconds past the atime that the item was last accessed. Displays the subreport with the specified ID. If snapshots generated for the replication policy on the source cluster are retained, specifies an expiration period for the snapshots. Specifies that a symbolic link was modified. Displays information about the replication performance rule with the specified ID. However, data that was previously replicated to the local cluster is still available. Specifies a description of this performance rule. Any directories specified by this setting are not replicated. You can create network-traffic rules that control the amount of network traffic generated by replication jobs during specified time periods. Sorts output by whether archival snapshots are retained on the source cluster. This can be useful if you do not want other users on the cluster to see the password you specify. The following values are valid: If a file is deleted in the source directory, the file is not deleted in the target directory. Whether the policy is enabled or disabled. Record when a synchronization deletes files or directories. When a client connects to the secondary cluster, their data appears as it was when the last successful replication job was started. The RTO is always less than or approximately equal to the RPO, depending on the rate at which replication jobs are created for a given policy. Prevent specific files from being replicated by specifying file matching criteria. Because you can fail back only synchronization policies, it is not necessary to create SyncIQ domains for copy policies. If an associated replication job is not running, ensure that the SyncIQ license is active on the cluster. Failback is not supported for copy policies. A differential replication consumes less network bandwidth than a full replication; however, differential replications consume more CPU. /ifs/data from being replicated. Restricts replication jobs to running only on nodes in the specified pool on the local cluster. 152, Specifies a password to access the target cluster. You can view information about replication policies through the Sorts output by when the replication job ended. Includes or excludes files based on when the file was last modified. Failover is performed per replication policy; to migrate data that is spread across multiple replication policies, you must initiate failover for each replication policy. By default, only run the node on the lowest devid. If this option is set to Isilon uses a round robin approach to connections. car[-s] matches Explore and compare EMC products in the EMC Store, and get a price quote from EMC or an EMC partner. Depending on the amount of data being replicated, a full or differential replication can take a very long time to complete. Deleting a replication policy breaks the target association on the target cluster, and allows writes to the target directory. The number of files that have been transferred, and the total size of all transferred files. Customers are responsible for creating their own X.509 certificates, and SyncIQ peers must store each other’s end entity certificates.
