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. Any drives and/or nodes to be removed are marked with OneFS restripe_from capability. A stripe unit is 128KB in size. Scans a directory for redundant data blocks and reports an estimate of the amount of space that could be saved by deduplicating the directory. Wikipedia. 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. These jobs are generally intended to run as minimally disruptive background tasks in the cluster, using spare or reserved capacity. In this final article of the series, well turn our attention to MultiScan. If a LIN is being restriped when a metatree transfer, it is added to a persistent queue, and this phase processes that queue. About Isilon . The coordinator will still monitor the job, it just wont spawn a manager for the job. Applies a default file policy across the cluster. Run automatically after a drive or node removal or failure, FlexProtect locates any unprotected files on the cluster and repairs them as quickly as possible. When a new node or drive is added to the cluster, its blocks are almost entirely free, whereas the rest of the cluster is usually considerably more full, capacity-wise. The scale-out NAS storage platform combines modular hardware with unified software to harness unstructured data. 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. FlexProtect may have already repaired the destination of a transfer, but not the source. isi job schedule set mediascan "the 15th every 3 month every 2 hours from 10:00 to 16:00". Locates and clears media-level errors from disks to ensure that all data remains protected. This phase needs to progress quickly and the job engine workers perform parallel execution across the cluster. However, with the marking exclusion set, OneFS can only accommodate a single marking job at any point in time. Scan the file system after a device failure to ensure that all files remain protected. Once youre happy with everything, press the small black power button on the back of the system to boot the node.
