You can also include a range of days by specifying two values separated by a dash. The number of bytes between the start of the changelist entry structure and the null-terminated UTF-8 string that contains the root path of the snapshots. When the next job is scheduled to run. Determines whether OneFS performs a checksum on each file data packet that is affected by a replication job. To resume replication for a disabled policy, you must either fix the error that caused the policy to be disabled, or reset the replication policy. Determines whether SyncIQ retains a log of all files that are deleted when a synchronization policy is run. car-. The best of EMC+ from breaking news and technology stories to in depth reporting all in one place. --target-compare-initial-sync option. Run the policy only on nodes in the specified subnet and pool. 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. If a replication job fails due to an error, SyncIQ might disable the corresponding replication policy. You can create rules that limit the network traffic created and the rate at which files are sent by replication jobs. A file matching criterion consists of a predicate, an operator, and a link. Matches any string in place of the asterisk. Run the policy on all nodes in this cluster, Run the policy only on nodes in the specified subnet and pool. Specifies the number of workers per node that are generated by SyncIQ to perform each replication job for the policy. Displays information about only replication jobs in the specified state. This will delete the policy from the local cluster only and not break the target association on the target cluster. Failback is not supported for replication policies that exclude directories. File sizes are represented in multiples of 1024, not 1000. Replication jobs are the operations that replicate data from one Isilon cluster to another. /ifs directory, the entire target cluster is set to a read-only state, which prevents you from storing any other data on the cluster. Here are some some useful Isilon commands to assist you in troubleshooting Isilon storage array issues. tap, /ifs/data from being replicated. You can view the information contained in changelists. The type of changelist entry. Once SyncIQ has been enabled by the cluster admin, a global encryption flag is automatically set, requiring all SyncIQ policies to be encrypted. Cancels a running or paused replication job. You can specify to include or exclude full or partial names that contain specific text. Record when a synchronization deletes files or directories. For example, you might allocate a small amount of network bandwidth during peak business hours, but allow unlimited network bandwidth during non-peak hours. This change occurs because SyncIQ internally records report retention times in seconds and then converts them into days, weeks, months, or years for display. /ifs/.snapshot directory or subdirectory of it. This predicate is valid only for copy policies. Specifies when the item was last accessed. /ifs/data on the source cluster to For example, if the root directory is /ifs/data/archive directory is not replicated regardless of whether the directory is explicitly excluded. For example, changing the DNS record of the target cluster could cause this problem. You can use any replication policy to fail over. For example, the following command enables differential synchronization for newPolicy: You can create and view changelists that describe what data was modified by a replication job. on, performs a differential replication. --password. You can create multiple network traffic rules to enforce different limitations at different times. You can create a file-operations rule that limits the number of files that replication jobs can send per second. Breaking a source and target association requires you to reset the replication policy before you can run the policy again. This setting applies only if the Target Host is specified as a SmartConnect zone. For example, For example, the following command enables writes to the target directory of SmartLockSync: Snapshots are located under the hidden The fully qualified domain name (FQDN) of any node in the target cluster. Commands required on Isilon cluster v8. Add an "Or" condition or The following values are valid: Specifies that a regular file was modified. Breaking the association between a source and target cluster causes the mark on the target cluster to be deleted. Displays any job-related actions that you can perform. Specifies a description of this performance rule. Complete the following procedure for each replication policy that you want to fail over. If you specify a directory to exclude, files and directories under the excluded directory are not replicated to the target cluster. If a SnapshotIQ license has been activated on the target cluster, you can configure SyncIQ to generate archival snapshots on the target cluster that are not automatically deleted when subsequent replication jobs run. When opening a new case include output from "uname -a" & "isi_hw_status -i", and run isi_gather_info. The command will not succeed until SyncIQ can communicate with the target cluster; until then, the policy will still appear in the output of the You can configure any number of file-criteria definitions. Displays a sub report about the specified replication job. After a 3 hour Webex session, the engineer pointed to KB 334043. Introduction. When a replication job is completed, SyncIQ deletes the previous source-cluster snapshot and retains the most recent snapshot until the next job is run. Cloud Services: Accelerate Your IT Transformation. isi sync policies list command. /ifs/data/dir/file is modified at 1:10 PM, the modifications are not reflected on the target cluster, even if The following command creates a report about how much data will be transferred when weeklySync is run: The following command displays the assessment report for weeklySync: The following command replicates the source directory of weeklySync according to the snapshot HourlyBackup_07-15-2013_23:00: The following command resumes weeklySync: The following command cancels weeklySync: The following command displays detailed information about a replication job created by weeklySync: The following command fails over data for weeklySync: The following command sets newPolicy to run only manually: For example, the following command reverts a failover operation for newPolicy: The following command creates a mirror policy for weeklySync: SyncIQ names mirror policies according to the following pattern: You can replicate data either by manually starting the mirror policies or by modifying the mirror policies and specifying a schedule. /ifs/data/dir/ starts at 1:00 PM and finishes at 1:20 PM, and But how can I get the cluster to do this automagically and email it to me? You can view information about replication policies through the output of the The following wildcard characters are accepted: For example, Does not prompt you to confirm that you want to delete the performance rule. Looking for a version 8 command. After a replication job completes, SyncIQ generates a report that contains detailed information about the job, including how long the job ran, how much data was transferred, and what errors occurred. Even if you modify the name or IP address of the target cluster, the mark persists on the target cluster. Depending on the amount of data being synchronized or copied, a full and differential replications can take a very long time to complete. The source directory is not a SmartLock directory. /ifs/data from being replicated. If you fix the issue that caused the error, resolve the policy instead of resetting the policy. This procedure is available only through the command-line interface (CLI). Step 1: sudo su - to root Root user password is unique to the appliance and has no default. Failover is the process that allows clients to modify data on a secondary cluster. Displays a subreport about a completed replication job targeting the local cluster. metadata or This option is available for copy policies only. At the end of the failback process, you can redirect users to resume accessing their data on the primary cluster. You can also configure a replication policy to start when SyncIQ detects a modification to the source directory, so that SyncIQ maintains a more current version of your data on the target cluster. The source directory is the SmartLock directory that you are migrating. Sorts output by when the replication job ended. It is recommended that you consult Isilon Technical Support before disabling this option. How much time has elapsed since the job started. SyncIQ creates and references snapshots to replicate a consistent point-in-time image of a root directory. Pauses a job that was created according to the specified replication policy. This article explains using the skip_lookup SyncIQ setting, useful in situations where you NAT the Isilon IP addresses or have a split horizon DNS. The /ifs/data/archive directory has no effect because the Specifies the directory on the target cluster that files are replicated to. If neither Delete the copy of your SmartLock data on the source cluster. The following command enables changelists for newPolicy: The snapshots must have been generated sequentially for a replication policy. Breaking a source and target cluster association causes SyncIQ to perform a full replication the next time the policy is run. For example, consider an environment in which a replication policy is scheduled to run every three hours, and replication jobs take two hours to complete. This action does not affect the source cluster of the replication 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 SyncIQ skip_lookup flag is used to prevent local name resolution lookup of target nodes. values are valid: You can use the following SyncIQ generates one repstate file for each replication job. cars and All files are deleted from the target of a synchronization policy the first time that the policy is run. A file-criteria statement can include one or more elements. Each file-criteria element contains a file attribute, a comparison operator, and a comparison value. If a replication job remains paused for more than a week, SyncIQ automatically cancels the job. Reports table. You cannot specify the Full or differential replications are performed the first time a policy is run and after a policy has been reset. For an Isilon cluster, the RPO is the amount of time that has passed since the last completed replication job started. Determines whether SyncIQ checks the target directory for modifications before replicating files. When a job is created for a replication policy, SyncIQ checks whether it is the first job created for the policy. Files that do not meet the specified criteria will not be replicated to the target cluster. Sorts output by warnings that the replication job triggered. When a replication job is completed, SyncIQ deletes the previous source-cluster snapshot and retains the most recent snapshot until the next job is run. Isilon uses a round robin approach to connections. If you modify the IP or domain name of a target cluster, and then modify the replication policy on the source cluster to match the new IP or domain name, a full replication is not performed. The following job statuses are possible: Indicates how long the job took to complete. Specify as a replication policy name or a replication policy ID. 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. You can match a dash within a bracket if it is either the first or last character. After you complete the failback process, you can modify the policy to run according to a schedule again. You can use synchronization policies to fail over and fail back data between source and target clusters. Forcing a policy to delete might cause errors if an associated replication job is currently running. If specified, a snapshot is not generated for the replication job. For example, Includes or excludes files based on when the file was last modified. Selects files based on whether they are owned by the group of the specified ID. If you cannot resolve the issue that caused the error, you can reset the replication policy. Specifies whether replication jobs connect to any nodes in the cluster or if jobs can connect only to nodes in a specified pool. If this happens, modify the replication policy so that it is set to run only manually, resolve the policy, and complete the failback process. Specifies that a first-in-first-out (FIFO) queue was modified. Cancel Running Job. For more information about POSIX regular expressions, see the BSD man pages. Although you cannot fail over or fail back SmartLock directories, you can recover SmartLock directories on a target cluster. Cutting-edge video productions investigating Data Science, IT Transformation & Security. This option is available for copy policies only, and only if the global access-time-tracking option of the cluster is enabled. Selects files that were created at the specified time. You can fail over and fail back to facilitate scheduled cluster maintenance. Snapshots generated by SyncIQ can also be used for archival purposes on the target cluster. Resetting a replication policy causes either a full replication or a differential replication to be performed the next time the policy is run. Not deleting a policy association on the target cluster will cause the target directory to remain in a read-only state. Forces the replication policy association to be removed, even if an associated job is currently running. /ifs/data/media/temp/file.txt. No more than five running and paused replication jobs can exist on a cluster at a time. RPO is the maximum amount of time for which data is lost if a cluster suddenly becomes unavailable. --source-network option of the The path of the target directory on the target cluster. Temporarily disables a replication policy. Displays information about the specified replication policy. Sorts output by the schedule of the policy. Depending on the amount of data being replicated, a full or differential replication can take a very long time to complete.
