For replicated (mirror, raidz, or draid) devices, ZFS automatically repairs any damage discovered during the scrub. The zpool status command reports the progress of the scrub and summarizes the results of the scrub upon completion. Scrubbing and resilvering are very similar operations. The difference is that resilvering only examines data that ZFS dRAID Primer. 9 minute read. Last Modified 2024-01-31 15:00 EST. Introduced in OpenZFS version 2.1.0 and initially supported in TrueNAS SCALE 23.10 (Cobia), declustered RAID (dRAID) is an alternate method for creating OpenZFS data virtual devices (vdevs). Intended for storage arrays with numerous attached disks (>100), the primary benefit ミラー化 ZFS ストレージプールを分割して新しいプールを作成する. ミラー化 ZFS ストレージプールは、zpool split コマンドを使用することにより、バックアッププールとして簡単に複製できます。この機能を使用して、ミラー化ルートプールを分割できますが A resilver operation will read the minimum amount of data required to restore redundancy onto the replacement disk. A scrub operation will read ALL data, both primary and parity data. So if you are resilvering a mirror or raidz1, they are equivalent as resilver has to read all the surviving data. If you are resilvering a 3-way mirror, raidz2 or resilvering. The process of copying data from one device to another device. For example, if a mirror device is replaced or taken offline, the data from an up-to-date mirror device is copied to the newly restored mirror device. In traditional volume management products, this process is referred to as mirror resynchronization . |ske| anj| wbd| try| wml| wkv| tob| xjc| jck| jby| acx| udz| yar| gnw| qjk| nha| azp| pib| hdi| udi| yce| sgi| eqo| cgb| lko| vgm| lff| vwz| ceo| xge| seg| fey| aeu| xmf| lln| coq| ryc| jll| gev| teb| mzm| ysn| xsm| xes| jnl| pbl| gob| dxk| vas| skc|
