Isilon FlexProtect protects data in the cluster based on the configured protection policy, quickly rebuilding failed disks, harnessing free storage space across the entire cluster to further prevent data loss, and monitoring and preemptively migrating data off of at-risk components. How Many Questions Of E20-555 Free Practice Test. Performs a LIN-based scan for files to be managed by CloudPools. EMC Isilon OneFS overview OneFS combines the three layers of traditional storage architecturesfile system, volume manager, and data protectioninto one unified software layer, creating a single intelligent distributed file system that runs on an Isilon storage cluster. Given this, FlexProtect is arguably the most critical of the OneFS maintenance jobs because it represents the Mean-Time-To-Repair (MTTR) of the cluster, which has an exponential impact on MTTDL. This flexibility enables you to protect distinct sets of data at higher than default levels. This flexibility enables you to protect distinct sets of data at higher than default levels. Job operation. 1. OneFS protects files as the data is being written. AutoBalance and/or Collect are typically only run manually if MultiScan has been disabled. The solution should have the ability to cover storage needs for the next three years. A jobs resource usage can be traced from the CLI as such: Finally, upon completion, the Multiscan job report, detailing all four stages, can be viewed by using the following CLI command with the job ID as the argument: Your email address will not be published. In addition to FlexProtect, there is also a FlexProtectLin job. isi job schedule set mediascan "the 15th every 3 month every 2 hours from 10:00 to 16:00". : Unlike previous releases, in OneFS 8.2 and later FlexProtect does not pause when there is only one temporarily unavailable device in a disk pool, when a device is smart failed or dead. There are two WDL attributes in OneFS, one for data and one for metadata. The scale-out NAS storage platform combines modular hardware with unified software to harness unstructured data. Yes, disk queues are quite high for a few drives on the node which has the drive that are smartfailing. The OneFS Web Administration Guide describes how to activate licenses, configure network interfaces, manage the file system, provision block storage, run system jobs, protect data, back up the cluster, set up storage pools, establish quotas, secure access, migrate data, integrate with other applications, and monitor an EMC Isilon cluster. This phase scans the OneFS LIN tree to addresses the drive scan limitations. Pool-based tree reporting in FSAnalyze (FSA), Partitioned Performance Performing for NFS. However, you can run any job manually or schedule any job to run periodically according to your workflow. jobs.common.lin_based_jobs Execute the script isilon_create_users. An Isilon cluster is designed to continuously serve data, even when one or more components simultaneously fail. Processes the WORM queue, which tracks the commit times for WORM files. While AutoBalance will execute each time the MultiScan job is triggered, Collect typically wont be run more often that once every 2 weeks. As weve seen throughout the recent file system maintenance job articles, OneFS utilizes file system scans to perform such tasks as detecting and repairing drive errors, reclaiming freed blocks, etc. Enter the email address you signed up with and we'll email you a reset link. C. SmartConnect to direct clients to an external Hadoop NameNode and to SMB shares so data ingest, analytics, and results phases are transparently directed. If yes, please create SR. As it looks like multiple disks are Smartfailing at same time, FlexProtectLIN are not working properly. Description. After a component failure, lost data is restored on healthy components by the FlexProtect proprietary system. If AutoBalance is enabled, the system runs it automatically when a device joins (or rejoins) the cluster. The successfully repaired nodes and drives that were marked restripe from at the beginning of phase 1 are removed from the cluster in this phase. Regards, Dnyaneshwar, Dell Community Forum Enterprise Storage Support. Introduction to file system protection and management. And what happens when you replace the drive ? However, with the marking exclusion set, OneFS can only accommodate a single marking job at any point in time. In addition, OneFS starts some jobs automatically when particular system conditions arisefor example, FlexProtect or FlexProtectLin, which start when a drive is smartfailed. The target directory must always be subordinate to the. You could pause FlexProtect job and run other job by removing job engine from "Degraded" mode, but at this stage again I would ask you to check with support . While there is a device failure on a cluster, only the FlexProtect (or FlexProtectLin) job is allowed to run. The environment consists of 100 TBs of file system data spread across five file systems. This section describes OneFS administration using the Storage as-a-Service UI. Will it kick off a autobalance job to restripe data from the other drives onto the new drive? This means that the job will consume a minimum amount of cluster resources. Last month Ive performed a Isilon tech refresh of two clusters running NL400 nodes. Note that all progress is reported per phase, with MultiScan phase 1 being the one where the lions share of the work is done. Wikipedia. The FlexProtect job includes the following distinct phases: In addition to FlexProtect, there is also a FlexProtectLin job. I have tried to search documents to get answers, but can't find anything. Uses a template file or directory as the basis for permissions to set on a target file or directory. By comparison, phases 2-4 of the job are comparatively short. National Life Group is a trade name of National Life Insurance Company, founded in Montpelier, Vt., in 1848, Life Insurance Company of the Southwest, Addison, Texas, chartered in 1955, and their affiliates. First, the in-use blocks and any new allocations are marked with the current generation in the Mark phase. isi_for_array -q -s smbstatus | grep. If the cluster is all flash, you can disable this job. If you notice that other system jobs cannot be started or have been paused, you can use the. If a cluster component fails, data stored on the failed component is available on another component. LINs with the needs repair flag set are passed to the restriper for repair. Cluster needs to be restriped but FlexProtect is not running: Cluster has Job has failed: This alert indicates job has failed. See the table below for the list of alerts available in the Management Pack. After a component failure, lost data is restored on healthy components by the FlexProtect proprietary system. 9. We anticipate that the initial public offering price will be between $11.00 and $12.00 per share. OneFS ensures data availability by striping or mirroring data across the cluster. Like which one would be the longest etc. Any additional nodes and drives which were subsequently failed remain in the cluster, with the expectation that a new FlexProtect job will handle them shortly. Saw broken pipe errors on some nodes when I issued all cluster commands to retrieve health status so I issued a 'isi config' followed by 'reboot all' to clear the issue. For example: Your email address will not be published. Isilon OneFS v8. The Isilon IQ Accelerator was designed to enable enterprises with high performance storage requirements to meet their most demanding challenges by modularly and cost-effectively scaling single-stream performance to more than 400 MB/second and throughput of over 45 gigabytes per second (GBps), all at one-third the cost of traditional storage. If I recall correctly the 12 disk SATA nodes like X200 and earlier. Cluster health - most jobs cannot run when the cluster is in a degraded state. AutoBalance restores the balance of free blocks in the cluster. Run automatically after a drive or node removal or failure, FlexProtect locates any unprotected files on the cluster, and repairs them as rapidly as possible. The lower the priority value, the higher the job priority. Flexprotect - what are the phases and which take the most time? Job priorities determine the precedence of a job when more than the maximum number of jobs attempt to run simultaneously. You can manage the impact policies to determine when a job can run and the system resources that it consumes. # isi job jobs view 274 ID: 274 Type: FlexProtect State: Succeeded Impact: Medium Policy: MEDIUM Pri: 1 Phase: 6/6 Start Time: 2020-12-04T17:13:38 Running Time: 17s Participants: 1, 2, 3 Progress: No work needed Waiting on job ID: - Description: {"nodes": "{}", "drives": "{}"} To administer jobs at the command line, use these commands: isi status isi job. Part 5: Additional Features. Trying to copy the remain data off the soft_failed drive to the other drives in the cluster? The Micron enterprise line of SSD 7450 vs 9300? When you create a local user, OneFS automatically creates a home directory for the user. FlexProtect scans the clusters drives, looking for files and inodes in need of repair. For example, a job with priority value 1 has higher priority than a job with priority value 2 or higher. 2, health checks no longer require you to create new controllers like in the example. In this final phase, FlexProtect removes successfully repaired drives or nodes from the cluster. FlexProtect is responsible for maintaining the appropriate protection level of data across the cluster. Rebalances disk space usage in a disk pool. Scans the file system after a device failure to ensure that all files remain protected. Locates and clears media-level errors from disks to ensure that all data remains protected. The target directory must always be subordinate to the. Press question mark to learn the rest of the keyboard shortcuts. And then rebuild the data it can't read from the drive from the "redundant" blocks on the other drives/nodes to the other drives/nodes? Creates free space associated with deleted snapshots. Upgrades the file system after a software version upgrade. In both clusters, the old NL400 36TB nodes were replaced with 72TB NL410 nodes with some SSD capacity. Requested protection settings determine the level of hardware failure that a cluster can recover from without suffering data loss. By comparison, phases 2-4 of the job are comparatively short. Oh and EMC claims that Flexprotect is much better and faster than RAID rebuilds. Hello everyone, So just like the title says, I am wondering if anyone has any information regarding what does each phase of flexprotect do and maybe the time each phase takes in relation to other phases. Flexprotect - what are the phases and which take the most time? zeus-1# isi services -a | grep isi_job_d. The cluster is said to be in a degraded state until FlexProtect (or FlexProtectLin) finishes its work. If the clusters nodes contain SSDs, AutoBalanceLin (as opposed to the regular AutoBalance job) runs most efficiently by performing a LIN scan using a flash-backed metadata mirror. You can run any job manually, and you can create a schedule for most jobs according to your workflow. A subreddit for enterprise level IT data storage-related questions, anecdotes, troubleshooting request/tips, and other related discussions. FlexProtectLin typically offers significant runtime improvements over its conventional disk-based counterpart. A customer has a supported cluster with the maximum protection level. Balances free space in a cluster, and is most efficient in clusters when file system metadata is stored on solid state drives (SSDs). When you create a local user, OneFS automatically creates a home directory for the user. You can specify these snapshots from the CLI. The coordinator will still monitor the job, it just wont spawn a manager for the job. hth. Correct Answer: A QUESTION 9 A customer has a supported cluster with the maximum protection level. C. SmartConnect to direct clients to an external Hadoop NameNode and to SMB shares so data ingest, analytics, and results phases are transparently directed. A flex protect job can follow these inode trails, locate the ones that point to defunct blocks or lack the proper number of blocks, then it can make sure the required number of copies of each block are present and valid. It's different from a RAID rebuild because it's done at the file level rather than the disk level. Job Engine starts a rebalance job when there is an imbalance of 5% or more between any two drives, and when Job Engine determines that rebalancing should be LIN-based. In this final article of the series, well turn our attention to MultiScan. By default, runs on the second Saturday of each month at 12am. A common reason for drives to end up more highly used than others is the running of a FlexProtect job type. In line dedupe will not permit block sharing across different hardware types or from C S 4113 at The University of Oklahoma Greater Minneapolis-St. Paul Area. The first phase of our Health Check process focuses on data gathering. This is 'Phase 1' of the FSAnalyze job but sometimes this is not the part that takes the longest since this phase is multithreaded and the work is split between the nodes in the cluster. First step in the whole process was the replacement of the Infiniband switches. The environment consists of 100 TBs of file system data spread across five file systems. Other jobs will automatically be paused and will not resume until FlexProtect has completed and the cluster is healthy again. FlexProtect may have already repaired the destination of a transfer, but not the source. setting to determine whether to run FlexProtect or FlexProtectLin. The job engine coordinator notices that the group change includes a newly-smart-failed device and then initiates a FlexProtect job in response. Balances free space in a cluster, and is most efficient in clusters that contain only hard disk drives (HDDs). isi job status File filtering enables you to allow or deny file writes based on file type. I would greatly appreciate any information regarding it. So I don't know if its really that much better and faster as they claim. This allows FlexProtect to quickly and efficiently re-protect data without critically impacting other user activities. You can specify these snapshots from the CLI. The solution should have the ability to cover storage needs for the next three years. I guess it then will have to rebuild all the data that was on the disk. Balances free space in a cluster.
