Required fields are marked *. This job should be run manually in off-hours after setting up all quotas, and whenever setting up new quotas. Gathers and reports information about all files and directories beneath the. If a cluster component fails, data stored on the failed component is available on another component. For example, it ensures that a file which is configured to be protected at +2n, is actually protected at that level. As such, the primary purpose of FlexProtect is to repair nodes and drives which need to be removed from the cluster. I would greatly appreciate any information regarding it. Scan the file system after a device failure to ensure that all files remain protected. Within OneFS, a LIN Tree reference is placed inside the inode, a logical block. As such, AutoBalance runs if a clusters nodes have a greater than 5% imbalance in capacity utilization. OneFS supports two types of permissions data on files and directories that control who has access: Windows-style access control lists (ACLs) and POSIX mode bits (UNIX permissions). FlexProtect falls within the job engines restriping exclusion set and, similar to AutoBalance, comes in two flavors: FlexProtect and FlexProtectLin. I think we might have a quite high number of inodes (around 4.0M on each drive with low queue and 4.7M on the ones with high queues) maybe that has something to do with it. That is the amount of data that Isilon will try to write to each disk drive, using a block size of 8KB. This job should be run manually in off-hours after setting up all quotas, and whenever setting up new quotas. it's only a cabling/connection problem if your're lucky, or the expander itself. Associates a path, and the contents of that path, with a domain. A stripe unit is 128KB in size. Question #16. The time to SmartFail a node will depend on a number of variables such as; node type, amount of data on node(s), capacity within cluster, average file size, cluster load and job impact setting. then find the PID from the results and then run this to get the user. D. If you are noticing slower system response while performing administrative tasks, you. Performs a treewalk scan on a given file path to identify files to be managed by CloudPools. Other jobs will automatically be paused and will not resume until FlexProtect has completed and the cluster is healthy again. 65 Job Administration. Job Engine jobs often comprise several phases, each of which are executed in a pre-defined sequence. A customer has a supported cluster with the maximum protection level. Requested protection settings determine the level of hardware failure that a cluster can recover from without suffering data loss. : 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. FlexProtect is responsible for maintaining the appropriate protection level of data across the cluster. They have something called a soft_failed drive, at least that's what I can see in the logs. Introduction to file system protection and management. OneFS does not check file protection. An. Scans the file system after a device failure to ensure that all files remain protected. This allows FlexProtect to quickly and efficiently re-protect data without critically impacting other user activities. The FlexProtect job includes the following distinct phases: Drive Scan. OneFS enables you to modify the requested protection in real time while clients are reading and writing data on the cluster. (Stalled drives are bad, and can cause cluster problems. isi job schedule set fsanalyze "the 3 Sun every 2 month at 16:00". If AutoBalance is enabled, the system runs it automatically when a device joins (or rejoins) the cluster. DELL EMC E20-555 exam is the qualifying exam for Specialist-Technology Architect, PowerScale Solutions (DCS-TA) certification. Runs automatically on group changes, including storage changes. On the Start Job page, in the Job list, select the appropriate FlexProtect job for the node. It's different from a RAID rebuild because it's done at the file level rather than the disk level. If you have files with no protection setting, the job can fail. OneFS ensures data availability by striping or mirroring data across the cluster. This phase ensures that all LINs were repaired by the previous phases as expected. Perform audits on Isilon and Centera clusters. If a LIN is being restriped when a metatree transfer, it is added to a persistent queue, and this phase processes that queue. The parity overhead for N + M protection depends on the file size and the number of nodes in the cluster. Set both maxhealth and health to an infinite value chr. This job is scheduled to run every 1st Saturday of every month at 12 a.m. The regular version of FlexProtect has the following phases: Be aware that prior to OneFS 8.2, FlexProtect is the only job allowed to run if a cluster is in degraded mode, such as when a drive has failed, for example. Regards, Dnyaneshwar, Dell Community Forum Enterprise Storage Support. isi job status You can specify these snapshots from the CLI. Run as part of MultiScan, or automatically by the system when a device joins (or rejoins) the cluster. planning several upgrades over the next three years in the following stages: Stage 1: Add 2 X-Series nodes to meet performance growth. Isilon Foundations. If you run an isi statistics are you seeing disk queues filling up? 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. In both clusters, the old NL400 36TB nodes were replaced with 72TB NL410 nodes with some SSD capacity. After a component failure, lost data is restored on healthy components by the FlexProtect proprietary system. At a +1 protection level, you will have one Forward Error Correction unit per stripe unit as seen here: Hybrid Level and Mirroring Protection Earlier I mentioned +2:1 and +3:1 protection levels. The scale-out NAS storage platform combines modular hardware with unified software to harness unstructured data. Correct Answer: A QUESTION 9 A customer has a supported cluster with the maximum protection level. Cluster health - most jobs cannot run when the cluster is in a degraded state. Job has failed: Cluster has Job phase begin: This alert indicates job phase begin. I had to change the Impact from Medium to Low because it was making NFS access slow and causing a lot of severs to go haywire. 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. 3256 FlexProtect Failed 2018-01-02T09:10:08. Note: The isi_for_array command runs the command on all of the nodes. A job phase must be completed in entirety before the job can progress to the next phase. FlexProtectLin typically offers significant runtime improvements over its conventional disk-based counterpart. For example, a job with priority value 1 has higher priority than a job with priority value 2 or higher. A FlexProtect job will start a priority of 1, which will cause any other running jobs to pause until the SmarFail process completes. Flexprotect - what are the phases and which take the most time? AutoBalance and/or Collect are typically only run manually if MultiScan has been disabled. By default, system jobs are categorized as either manual or scheduled. The following CLI syntax will kick of a manual job run: The FlexProtect jobs progress can be tracked via a CLI command as follows: Upon completion, the FlexProtect job report, detailing all six stages, can be viewed by using the following CLI command with the job ID as the argument: While a FlexProtect job is running, the following command will detail which LINs the job engine workers are currently accessing: Using the isi get -L command, a LIN address can be translated to show the actual file name and its path. A. Feb 2019 - Present2 years 8 months. In addition to automatic job execution after a drive or node removal or failure, FlexProtect can also be initiated on demand. This flexibility enables you to protect distinct sets of data at higher than default levels. OneFS SmartQuotas Accounting and Reporting, Explaining Data Lakehouse as Cloud-native DW, Restores node and drive free space balance, Replaces the traditional RAID rebuild process, Run AutoBalance and Collect jobs concurrently. (FlexProtect ad FlexProtectLin continue to run even if there are failed devices.) A B-Tree describes the mapping between a logical offset and the physical data blocks: In order for FlexProtect to avoid the overhead of having to traverse the whole way from the LIN Tree reference -> LIN Tree -> B-Tree -> Logical Offset -> Data block, it leverages the OneFS construct known as the Width Device List (WDL). Because all data, metadata, and parity information is distributed across all nodes, the cluster does not require a dedicated parity node or drive. LIN Verification. FlexProtect distributes all data and error-correction information Scans a directory for redundant data blocks and deduplicates all redundant data stored in the directory. 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. Processes the WORM queue, which tracks the commit times for WORM files. Pool-based tree reporting in FSAnalyze (FSA), Partitioned Performance Performing for NFS.

Reclaims free space from previously unavailable nodes or drives. By comparison, phases 2-4 of the job are comparatively short. Uses a template file or directory as the basis for permissions to set on a target file or directory. Increasing the requested protection of data also increases the amount of space consumed by the data on the cluster. You can generate reports for system jobs and view statistics to better determine the amounts of system resources being used. In this final phase, FlexProtect removes successfully repaired drives or nodes from the cluster. Collects mark and sweep gets its name from the in-memory garbage collection algorithm. You can run any job manually, and you can create a schedule for most jobs according to your workflow. Well I have a soft_failed 4TB drive that has a FlexProtect job running for 1 day and 14 hours and its still running. View active jobs. In addition, OneFS starts some jobs automatically when particular system conditions arisefor example, FlexProtect or FlexProtectLin, which start when a drive is smartfailed. Scans the file system after a device failure to ensure that all files remain protected. It then starts a Flexprotect job but what does it do? This job runs on a regularly scheduled basis, and can also be started by the system when a change is made (for example, creating a compatibility that merges node pools). This phase needs to progress quickly and the job engine workers perform parallel execution across the cluster. If MultiScan is enabled, Job Engine runs the AutoBalance part of the MultiScan job. The list of participating nodes for a job are computed in three phases: Query the clusters GMP group. Data protection is specified at the file level, not the block level, enabling the system to recover data quickly. 9. This section describes OneFS administration using the Storage as-a-Service UI.
