Solaris 10 x86 - 嘗試替換 zpool 中的磁碟

Solaris 10 x86 - 嘗試替換 zpool 中的磁碟

我在更換 x86 處理器上執行 Solaris 10 的系統上現有 zpool 上的磁碟時遇到問題。 zpool 最初是用兩個鏡像切片建立的。其中一個驅動器出現故障，因此我將其物理更換為新驅動器。我運行 prvtoc 和 fmthard 將磁碟標籤從工作磁碟機複製到新磁碟機：

prtvtoc /dev/rdsk/c1t0d0s2 >/tmp/c1t0d0s2.out
fmthard -s /tmp/c1t0d0s2.out >/dev/rdsk/c1t1d0s2

然後我嘗試將新驅動器聯機，並收到有關設備仍然故障的警告：

$ zpool online pool c1t1d0s6 
warning: device 'c1t1d0s6' onlined, but remains in faulted state

zpool status -v 的輸出是：

NAME          STATE     READ WRITE CKSUM
pool          DEGRADED     0     0     0
mirror-0    DEGRADED     0     0     0
c1t0d0s6  ONLINE       0     0     0
c1t1d0s6  UNAVAIL      0     0     0  corrupted data

（c1t1d0 是替換的驅動器。）

然後我再次使 c1t1d0 離線並嘗試執行 zpool Replace 命令，但這也不起作用：

$ zpool replace pool c1t1d0s6
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c1t1d0s6 overlaps with /dev/dsk/c1t1d0s2

有人知道發生了什麼事嗎？使用“-f”標誌安全嗎？

編輯：運行 zpool Replace -f 後，我得到：

pool: pool
state: DEGRADED
status: The pool is formatted using an older on-disk format.  The pool can
        still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the
    pool will no longer be accessible on older software versions.
scrub: none requested
config:

      mirror-0          DEGRADED     0     0     0
        c1t0d0s6        ONLINE       0     0     0
        replacing-1     UNAVAIL      0     0     0  insufficient replicas

          c1t1d0s6      UNAVAIL      0   342     0  experienced I/O failures

我在 iostat -e 輸出中看到新驅動器上的錯誤。我猜新驅動器也可能很糟糕？

編輯2: 不知道怎麼回事。我用相同的過程嘗試了不同的驅動器。執行 zpool Replace -f 後，zfs 池運行清理，但狀態輸出為：

  pool: pool
 state: ONLINE
 status: The pool is formatted using an older on-disk format.  The pool can
    still be used, but some features are unavailable.
 action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the
    pool will no longer be accessible on older software versions.
 scrub: scrub completed after 12h56m with 0 errors on Wed Aug 29 06:49:16 2012
config:

    NAME                STATE     READ WRITE CKSUM
    pool              ONLINE       0     0     0
      mirror-0          ONLINE       0     0     0
        c1t0d0s6        ONLINE       0     0     0
        replacing-1     ONLINE   5.54M 19.9M     0
          c1t1d0s6/old  UNAVAIL      0     0     0  corrupted data
          c1t1d0s6      UNAVAIL      0     0     0  corrupted data

下線 c1t1d0s6 後，zpool status 輸出為：

  pool: pool
 state: ONLINE
status: The pool is formatted using an older on-disk format.  The pool can
    still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the
    pool will no longer be accessible on older software versions.
scrub: scrub completed after 12h56m with 0 errors on Wed Aug 29 06:49:16 2012
config:

    NAME                STATE     READ WRITE CKSUM
    pool                ONLINE       0     0     0
      mirror-0          ONLINE       0     0     0
        c1t0d0s6        ONLINE       0     0     0
        replacing-1     ONLINE   5.54M 19.9M     0
          c1t1d0s6/old  UNAVAIL      0     0     0  corrupted data
          c1t1d0s6      UNAVAIL      0     0     0  corrupted data

我不明白。系統不應該能夠使用 c1t0d0s6 上的鏡像來取代 c1t1d0s6 嗎？

答案1

您清除了警報嗎fmadm？而且zpool clear...使用開關運行 zpool Replace 是安全的-f，但我認為你的陳述是錯誤的，除非你已經刪除了壞磁碟。

答案2

檢查電纜或驅動器底座和插槽。吵雜的 SATA 連線會產生錯誤，fmadm 使用該資訊來確定裝置何時發生故障。我曾經有過一些我認為是壞的驅動器，但只是 ZFS 注意到它無法可靠地獲取有效數據。我注意到 SATA 電纜被擠壓，將其更換並運行zpool clear，zpool scrub沒有更多錯誤。
