私は最近、文字通りゼロについて知っているglusterfsセットアップを継承しました。ボリュームにブリックを提供するHDDの1つが故障し、そのHDDを交換することができ、ホストOSはHDDを認識できます。正常にフォーマットされ、交換されたHDDが交換されたHDDとしてマウントされた位置にあります。
ここで私は助けが必要です。
ある種の修復コマンドを実行する必要があると思いますが、GlusterFSでこれを実行する方法にかなり混乱しています。これが背景情報の一部です。
$ mount |grep glus
/dev/sdc1 on /data/glusterfs/sdc1 type xfs (rw,relatime,attr2,inode64,noquota)

/dev/sde1 on /data/glusterfs/sde1 type xfs (rw,relatime,attr2,inode64,noquota)
交換したHDDは/dev/sde1
です。 (上記のように)マウントし、glusterfs volume info
を実行すると、そこにリストされていることがわかります。

Glusterdを再起動すると、そのロックがフラッシュされますが、上記の修復コマンドが実際に何を伝えようとしているのか途方に暮れています。いくつかあるので私が役に立たないと思うログは、私には完全には明確ではありません。

OK、1つの問題は、マウントされたブリックのファイルシステムに拡張属性が存在しないことにあるようです。このコマンドはそれを修正することを想定しています:
$ 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
それでも、属性が存在しないという上記の警告が表示されます。

OK、それで私は次のことをしなければならなかったようです。

ディレクトリにある必要があることに注意してください。そこからレベルアップしてみましたが、機能しませんでした。
$ setfattr -n trusted.glusterfs.volume-id -v 0xf0d72d64288c4e729c532d16ce5687ac /data/glusterfs/sde1/brick
注:volume-idの値は、次のコマンドから取得されます。
