SyncIQ generates snapshots on the source cluster to ensure that a consistent point-in-time image is replicated and that unaltered data is not sent to the target cluster. Disabling this option could result in data loss. Displays only replication reports whose jobs are in the specified state. 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. You must specify the directories and files you want to replicate. The target directory on the target cluster. This setting applies only if the Target Host is specified as a SmartConnect zone. --source-include-directories multiple times within a command. These rules can be useful if, for example, you want to limit the amount of network traffic created during other resource-intensive operations. Copy policies enable you to remove files from the source cluster without losing those files on the target cluster. 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. SyncIQ skip_lookup flag. 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. Sorts output by the last time that a replication job completed successfully. Sorts output by the ID of the replication job. You can view information about replication jobs that are currently running or paused. Specifies the type of replication policy. inprog is appended to the changelist ID. Specifies that a character device was modified. You can also include the wildcard characters If the target cluster requires a password for authentication purposes, you must specify this parameter or Through the OneFS command line, enable changelists for a replication policy, and then run the policy at least twice. /ifs/.snapshot directory. This predicate is valid only for copy policies. Matches any characters contained in the brackets, or a range of characters separated by a dash. Specifies the maximum number of replication reports that are retained for this policy. Because each node in a cluster is able to send and receive data, the speed at which data is replicated increases for larger clusters. OneFS isi commands A through C This chapter contains documentation of the OneFS CLI commands isi antivirus policies create through isi config . Good Evening, I have a question about the worker maximum per node. 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. If a report is composed of subreports, the report is displayed as a folder. This option is available for copy policies only, and only if the global access-time-tracking option of the cluster is enabled. Before running a replication policy for the first time, you can view statistics on the files that would be affected by the replication without transferring any files. Cloud Services: Accelerate Your IT Transformation. When opening a new case include output from "uname -a" & "isi_hw_status -i", and run isi_gather_info. In addition, if you exclude a directory that contains the source directory, the exclude-directory setting has no effect. Sorts output by whether the target directory is read only. These rules can be useful if, for example, you want to limit the amount of network traffic created during other resource-intensive operations. If SyncIQ disables a replication policy due to a replication error, and you fix the issue that caused the error, you can resolve the replication policy. Before running a replication job, SyncIQ creates a snapshot of the source directory. --source-exclude-directories directories must be contained in the included directories. On the primary cluster, modify the replication policy so that it is set to run only manually. Sorts output by directories that have been explicitly excluded in replication. You can create network-traffic rules that control the amount of network traffic generated by replication jobs during specified time periods. To restart replication, you must start the replication policy again. as any day of the week or a three-letter abbreviation for the day. If you specify a directory to include, only the files and directories under the included directory are replicated to the target cluster; any directories that are not contained in an included directory are excluded. Determines whether OneFS records when a synchronization job deletes files or directories on the target cluster. 142, For example, the following command automatically commits all files in. If you specify an existing directory on the target cluster, make sure that the directory is not the target of another replication policy. You can fail over to a secondary Isilon cluster if, for example, a cluster becomes unavailable. 10. For example, SyncIQ generates snapshots to facilitate replication, failover, and failback between Isilon clusters. Failback is not supported for replication policies that exclude directories. isi sync policies delete --policy --local-only . Determines whether archival snapshots are retained on the source cluster. Data replication commands apply specifically to the SyncIQ tool, and are available only if a SyncIQ license is configured on the cluster. SyncIQ also deletes reports after the number of reports exceeds the specified limit. Before failover is performed, you must create and run a replication policy on the primary cluster. If the specified target directory does not already exist on the target cluster, the directory is created the first time that the job is run. For example SyncIQ might disable a replication policy if the IP or hostname of the target cluster is modified. Breaking the association between a source and target cluster causes the mark on the target cluster to be deleted. If the target cluster requires a password for authentication purposes, you must specify this parameter or OneFS generates no more than 40 workers for a replication job. During a differential replication, SyncIQ first checks whether a file already exists on the target cluster and then transfers only data that does not already exist on the target cluster. You can configure the default amount of time that SyncIQ retains replication reports for. Sorts output by the ID of the replication subreport. Data failover is the process of preparing data on a secondary cluster to be modified by clients. A differential replication consumes less network bandwidth than a full replication; however, differential replications consume more CPU. Suppresses command-line prompts and messages. Specifies the ID of the job that created the changelist. The following types of replication policy are valid: Creates a copy policy that adds copies of all files from the source to the target. If SyncIQ disables the replication due to policy error then you can resolve it using below command: # isi sync policies resolve If you can't resolve the replication issue then you can reset the job as well. If set to 1[4-7]2 matches The number of files that have been transferred, and the total size of all transferred files. 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. If any SmartLock directory configuration settings, such as an autocommit time period, were specified for the source directories of the replication policies, apply those settings to the target directories. If the policy on the primary cluster runs a replication job while writes are allowed to the target directory, the job will fail and the policy will be set to an unrunnable state. This option is available for copy policies only. Displays information about a replication performance rule. A cancelled job releases its cluster resources and allows another replication job to consume those resources. You can temporarily suspend a replication policy from creating replication jobs, and then enable it again later. The number of changelist entries in the changelist. and Sorts output by the schedule of the policy. This parameter has no effect for copy policies. You can access archival snapshots the same way that you access other snapshots generated on a cluster. Sorts output by whether OneFS retains a log of all files that are deleted when the replication policy is run. Here in this post, we are discussing a few basic isilon commands. This step is necessarily only if you have configured an autocommit time period for the SmartLock directory. If multiple subreports are created for a job, SyncIQ combines the information from the subreports into a single report. 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. 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. /ifs/data on the target cluster. Restricts replication jobs to running only on nodes in the specified subnet on the local cluster. In this post I’m going to review the most useful commands for managing SyncIQ replication jobs and SnapshotIQ snapshots on the Isilon. You can recover SmartLock directories that you have replicated to a target cluster. It is recommended that you specify file-criteria statements in a replication policy only if necessary. You can cancel a currently running job that targets the local cluster, or you can break the association between a policy and its specified target. After the specified expiration period has passed for a report, SyncIQ automatically deletes the report. For example, if the root directory is 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 a replication policy is reset, SyncIQ performs a full or differential replication the next time the policy is run. During a full replication, SyncIQ transfers all data from the source cluster regardless of what data exists on the target cluster. OneFS enables you to replicate data from one Isilon cluster to another through the SyncIQ software module. Displays any report-related actions that you can perform. /ifs/data on the target cluster. If it is not the first job created for the policy, SyncIQ compares the snapshot generated for the earlier job with the snapshot generated for the new job. After you reset a replication policy, you must perform either a full or differential replication. The path of the target directory on the target cluster. movies and Specifies how archival snapshots are named on the target cluster. To migrate data that clients have modified on the secondary cluster, you must fail back to the primary cluster. The host name of any node in the target cluster. Displays a message confirming that the snapshot schedule was created. /ifs/data/media/temp/file.txt, SyncIQ will run newPolicy, but will not replicate 0. /ifs/data/media/file to be deleted from the target cluster. Thanks,-Don. You can view replication reports and subreports. You can include the following wildcard characters: Selects files that have been accessed since the specified time. The RPO is never greater than the time it takes for two consecutive replication jobs to run and complete. You must activate a SnapshotIQ license on the target cluster to generate archival snapshots on the target cluster. Specifies a description of this replication policy. Specifies the number of nanoseconds past the mtime that the item was last modified. File sizes are represented in multiples of 1024, not 1000. This predicate is valid only for copy policies. Includes or excludes files based on one of the following file-system object types: You can configure default settings for replication policies.
