Glusterfs
如何將替換 HDD 添加到 glusterfs 卷？
我最近繼承了一個 glusterfs 設置，我對它的了解幾乎為零。其中一個為卷提供磚塊的 HDD 出現故障，我能夠更換該 HDD，並且主機作業系統可以看到該 HDD。我已成功格式化它，它位於已更換的 HDD 現在作為它更換的 HDD 安裝的位置。
這是我需要幫助的地方。
我相信我需要執行某種修復命令，但對如何使用 GlusterFS 執行此操作感到困惑。這是一些背景資訊。
$ mount |grep glus /dev/sdc1 on /data/glusterfs/sdc1 type xfs (rw,relatime,attr2,inode64,noquota) /dev/sdg1 on /data/glusterfs/sdg1 type xfs (rw,relatime,attr2,inode64,noquota) /dev/sdf1 on /data/glusterfs/sdf1 type xfs (rw,relatime,attr2,inode64,noquota) /dev/sdb1 on /data/glusterfs/sdb1 type xfs (rw,relatime,attr2,inode64,noquota) /dev/sdd1 on /data/glusterfs/sdd1 type xfs (rw,relatime,attr2,inode64,noquota) 127.0.0.1:/nova on /var/lib/nova/instances type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) 127.0.0.1:/cinder on /var/lib/nova/mnt/92ef2ec54fd18595ed18d8e6027a1b3d type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) /dev/sde1 on /data/glusterfs/sde1 type xfs (rw,relatime,attr2,inode64,noquota)我更換的硬碟是
/dev/sde1. 我已經安裝了它（如上所示），當我執行時，glusterfs volume info我看到它在那裡列出：$ gluster volume info nova Volume Name: nova Type: Distributed-Replicate Volume ID: f0d72d64-288c-4e72-9c53-2d16ce5687ac Status: Started Number of Bricks: 10 x 2 = 20 Transport-type: tcp Bricks: Brick1: icicle07:/data/glusterfs/sdb1/brick Brick2: icicle08:/data/glusterfs/sdb1/brick Brick3: icicle09:/data/glusterfs/sdb1/brick Brick4: icicle10:/data/glusterfs/sdb1/brick Brick5: icicle11:/data/glusterfs/sdb1/brick Brick6: icicle07:/data/glusterfs/sdc1/brick Brick7: icicle08:/data/glusterfs/sdc1/brick Brick8: icicle09:/data/glusterfs/sdc1/brick Brick9: icicle10:/data/glusterfs/sdc1/brick Brick10: icicle11:/data/glusterfs/sdc1/brick Brick11: icicle07:/data/glusterfs/sdd1/brick Brick12: icicle08:/data/glusterfs/sdd1/brick Brick13: icicle09:/data/glusterfs/sdd1/brick Brick14: icicle10:/data/glusterfs/sdd1/brick Brick15: icicle11:/data/glusterfs/sdd1/brick Brick16: icicle07:/data/glusterfs/sde1/brick Brick17: icicle08:/data/glusterfs/sde1/brick Brick18: icicle09:/data/glusterfs/sde1/brick Brick19: icicle10:/data/glusterfs/sde1/brick Brick20: icicle11:/data/glusterfs/sde1/brick嘗試執行修復命令會導致：

好的，所以一個問題似乎是已安裝磚的文件系統上不存在擴展屬性。假設此命令可以解決此問題：
$ grep volume-id /var/lib/glusterd/vols/nova/info | cut -d= -f2 | sed 's/-//g' f0d72d64288c4e729c532d16ce5687ac $ setfattr -n trusted.glusterfs.volume-id -v 0xf0d72d64288c4e729c532d16ce5687ac /data/glusterfs/sde1然而，我仍然收到上述關於該屬性不存在的警告：

好的，看來我必須執行以下操作。
- 添加擴展屬性
trusted.glusterfs.volume-id- 注意它需要在/brick目錄中，我從那裡嘗試了一個級別，但它沒有工作$ setfattr -n trusted.glusterfs.volume-id -v 0xf0d72d64288c4e729c532d16ce5687ac /data/glusterfs/sde1/brick注意： volume-id 的值來自以下命令：
$ grep volume-id /var/lib/glusterd/vols/nova/info | cut -d= -f2 | sed 's/-//g' f0d72d64288c4e729c532d16ce5687ac
- 重新開始
glusterd$ service restart glusterd.service如果我再看磚的日誌：

- 完成後，執行一個修復命令來仔細檢查。
