isilon synciq commands


If set to /ifs/data/source on the local cluster to 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. Sorts output by whether data is sent over only the default interface of the subnet specified by the Specifies how long archival snapshots are retained on the target cluster before they are automatically deleted by the system. You can create a replication policy with SyncIQ that defines how and when data is replicated to another Isilon cluster. For example, the following command automatically commits all files in. Proper File Management The proper way to manage open files with Isilon is with the command line, via a product such as Putty. The following types of items might have been modified: A first-in-first-out (FIFO) queue was modified. Time settings are based on a 24-hour clock. After the first replication job created by a replication policy finishes, the target directory and all files contained in the target directory are set to a read-only state, and can be modified only by other replication jobs belonging to the same replication policy. Replication logs are typically used for debugging purposes. Break Association. The following list describes the log levels from least to most verbose: Replication logs are typically used for debugging purposes. The best of EMC+ from breaking news and technology stories to in depth reporting all in one place. Unlike previous OneFS versions, SyncIQ is disabled by default in the new OneFS 9.1 release. 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. --source-snapshot option. This setting applies only if the Target Host is specified as a SmartConnect zone. /ifs/data/media from replication, and Snapshots generated by SyncIQ can also be used for archival purposes on the target cluster. Because each node in a cluster is able to send and receive data, the speed at which data is replicated increases for larger clusters. SyncIQ creates a subreport each time the job is interrupted until the job completes successfully. However, you can prevent directories under the source directory from being replicated. /ifs/data/dir/file is not replicated until 1:15 PM. Sorts output by the maximum number of reports that are retained for the replication policy. For example, if the root directory is If a replication job remains paused for more than a week, SyncIQ automatically cancels the job. isi sync policies list command. The number of replication jobs that a single target cluster can support concurrently is dependent on the number of workers available on the target cluster. Reset a replication policy only if you cannot fix the issue that caused the replication error. 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. Displays information about a replication policy. For example, if the target directory is a compliance directory, the source must also be a compliance directory. Use Live Chat for fast, direct access to EMC Customer Service Professionals to resolve your support questions. If changelists are enabled for a policy, SyncIQ does not automatically delete the repstate files generated by the policy; if changelists are not enabled for a policy, SyncIQ automatically deletes the repstate files after the corresponding replication jobs complete. After creating a job for a replication policy, SyncIQ must wait until the job completes before it can create another job for the policy. For example, the following command enables writes to the target directory of SmartLockSync: Snapshots are located under the hidden 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. You can create rules that limit the network traffic created and the rate at which files are sent by replication jobs. Before failover is performed, you must create and run a replication policy on the primary cluster. The action determines how deleting a file on the source directory affects the target. The IPv4 or IPv6 address of any node in the target cluster. 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. For example, the following command automatically commits all files in. and Sorts output by the expiration period for archival snapshots retained on the source cluster. movies and 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. Clearing Events. The system intermittently deletes excess reports automatically. If you want to run the disabled policy again, you must reset the replication policy. For example, Resetting a policy causes OneFS to perform a full or differential replication the next time the policy is run. However, files that are deleted on the source cluster are not deleted from the target cluster. Determines whether the policy can connect to all nodes on the target cluster or can connect only to specific nodes. Failover snapshots are named according to the following naming pattern: Snapshots are stored in the Specifies the number of nanoseconds past the ctime that the item was last changed. Workers on the source cluster send data while workers on the target cluster write data. Specify which nodes you want replication policies to connect to when a policy is run. To copy all files from the source directory to the target directory, click Configuring the SyncIQ Policy Manually. You can configure a replication policy to run according to a schedule, so that you can control when replication is performed. This method can be useful if you want to replicate identical copies of data to multiple Isilon clusters. Specifies when the item was last accessed. 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. It is recommended that you attempt to fix the issue rather than reset the policy. 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. Because each node in a cluster is able to send and receive data, the speed at which data is replicated increases for larger clusters. After you complete the failback process, you can modify the policy to run according to a schedule again. The target directory on the target cluster. Isilon Community Network The Isilon Community Network connects you to a central hub of information and experts to help you maximize your current storage solution. Sorts output by the progress of the replication job. You initiate the failover process on the secondary cluster. 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. Determines which directories are excluded from replication. You can pause a running replication job and then resume the job later. Discuss specific issues with EMC experts. 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. SyncIQ generates replication jobs according to replication policies. By default, only run the node on the lowest devid. Specifies the maximum number of replication reports that are retained for this policy. April 2019 . The policies must meet the following requirements: You can replicate data either by manually starting the policies or by specifying a policy schedule. Does not break the target association on 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. You can exclude directories from being replicated by replication policies even if the directories exist under the specified source directory. BIC-Isilon-Cluster >>> lnnset LNN Device ID Cluster IP ----- 1 1 2 2 3 4 4 3 5 6 BIC-Isilon-Cluster-2# isi_nodes %{lnn} %{devid} %{external} %{dynamic} 1 1, 2 2, 3 4, 4 3, 5 6 … Displays only replication reports whose jobs are in the specified state. EMC Sales Specialists are standing by to answer your questions real time. Specifies the number of workers per node that are generated by SyncIQ to perform each replication job for the policy. Forcing a target break might cause errors if an associated replication job is currently running. /ifs/data on the target cluster. bit. 162, and You can create two types of replication policies: synchronization policies and copy policies. Changelist IDs include the IDs of both snapshots used to create the changelist. Entering a number of days that is equal to a corresponding value in weeks, months, or years results in the larger unit of time being displayed. For synchronization policies, if you modify the comparison operators or comparison values of a file attribute, and a file no longer matches the specified file-matching criteria, the file is deleted from the target the next time the job is run. For example, you can increase the maximum number of workers per node to increase the speed at which data is replicated to the target cluster. Includes or excludes files based on when the file was last accessed. /ifs/data/media/file exists on the target cluster, running the policy does not cause Help on Data Protection > SyncIQ > Local Targets; Help on Data Protection > SyncIQ > Performance Rules; Help on Data Protection > SyncIQ > Policies; Help on Data Protection > SyncIQ > Reports; Help on Data Protection > SyncIQ > Settings; Help on Data Protection > SyncIQ > Summary; Help on File System > Deduplication > Deduplication Settings The cluster on which the replication policy exists is the source cluster. Determines whether archival snapshots are generated on the target cluster. Specifies a description of this replication policy. Click Selects only files whose names match the specified POSIX regular expression. /ifs/data/archive directory has no effect because the You can optionally specify how archival snapshots are generated on the target cluster. Selects files that have not been modified since the specified time. Creates a replication policy report that reflects the number of files and directories that would be replicated if the specified policy was run. The source directory is the SmartLock directory that you are migrating. Alternatively, you can filter file names by using POSIX regular-expression (regex) text. This step will prevent the policy on the primary cluster from automatically running a replication job. Search failing IP’s across the cluster reported by zabbix . The number of changelist entries in the changelist. Displays any report-related actions that you can perform. SyncIQ Policies table. Creates a synchronization policy that synchronizes data on the source cluster to the target cluster and deletes all files on the target cluster that are not present on the source cluster. However, data that was previously replicated to the local cluster is still available. You configure replication policies to run according to replication policy settings. Record the IDs of the snapshots generated by the replication policy. Depending on the amount of data being replicated, a full or differential replication can take a very long time to complete. Main Page > Server Hardware > RAID Controllers > LSI. You must activate a SyncIQ license on both Isilon clusters before you can replicate data between them. Displays jobs that failed during the replication process. From this site, you can demonstrate Isilon products, ask questions, view technical videos, and get the latest Isilon product documentation. Breaking the association between a source and target cluster causes the mark on the target cluster to be deleted. Failover is performed per replication policy; to migrate data that is spread across multiple replication policies, you must initiate failover for each replication policy. Creating a SyncIQ domain [Required for failback operations] # isi job jobs start –root –dm-type SyncIQ. Specifies the path of the directory the changelist is for. Each file-criteria element contains a file attribute, a comparison operator, and a comparison value. /ifs/data/media/temp/file.txt. You can match a dash within a bracket if it is either the first or last character. tap, Includes only the specified directories in replication. The root path of the snapshots used to create the changelist. Failover snapshots are generated when a replication job completes. Do not modify the default setting without consulting Isilon Technical Support. If a replication policy encounters an issue that cannot be fixed (for example, if the association was broken on the target cluster), you might need to reset the replication policy. If necessary, you can log in to a node through the command-line interface and view the contents of the For an Isilon cluster, the RPO is the amount of time that has passed since the last completed replication job started. Determines whether archival snapshots are generated on the target cluster. I’ll add more over time. On the target cluster, enable writes to the target directories of the replication policies by running the. The information might be less useful when consumed through the command-line interface (CLI). However, you can prevent directories under the source directory from being replicated. Failover and failback can be useful in disaster recovery procedures. Configuring file-criteria statements can cause the associated jobs to run slowly. Before running a replication job, SyncIQ creates a snapshot of the source directory. Prevent clients from accessing the secondary cluster and then run each mirror policy again. Creates an empty changelist that you can manually populate for testing purposes. /ifs/data/media/temp/file.txt. Sorts output by the ID of the replication job. You cannot fail back replication policies that exclude files. b[aei]t matches The following wildcard characters are accepted: For example, To prevent permissions errors, make sure that ACL policy settings are the same across source and target clusters. The IP address or fully qualified domain name of the target cluster. For example, assume that newPolicy replicates The first step in the failback process is updating the primary cluster with all of the modifications that were made to the data on the secondary cluster. m* matches 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.
