更換磁碟故障

我的池中有一個磁碟故障（引發了太多錯誤）。

The number of I/O errors associated with a ZFS device exceeded
acceptable levels. ZFS has marked the device as faulted.

impact: Fault tolerance of the pool may be compromised.
   eid: 52
 class: statechange
 state: FAULTED
 host: databank-a
 time: 2021-12-11 16:36:33-0500
 vpath: /dev/disk02_old
 vphys: pci-0000:00:1f.2-ata-4
 vguid: 0x73F7B0B1D1B45864
 devid: /dev/disk02_old
 pool: 0x47B3E7C1336F1F4F

所以，我用一個全新的磁碟替換它zpool replace pool /dev/foo /dev/bar（zpool clear pool /dev/bar

驅動器沒有故障的可能性有多大？

驅動器沒有故障的可能性有多大？

可能驅動器有故障。如果錯誤計數器是正確的，那麼前幾 TB 使用中的幾十個錯誤比預期的要差。而且您已經清除了錯誤，因此這不是一次性的瞬態事件。

雖然Backblaze 消費者驅動器故障數據並不完全是您所擁有的，但它表明早期故障仍然存在。即使早死率很低，你也可能是幾千人中不幸的人，得到一個不太完美的產品。

開始對來自不同媒體的重要數據進行備份恢復測試，以防萬一在最壞的情況下需要。確保有更多的備用磁碟庫存。重新同步完成後，再次檢查磁碟。根據需要繼續更換它們。
