質問です。
CentOS5.3のmdadmのRAID5で、Rebuild Statusが30%completeぐらいで0%に戻ります。
rebuildしている状態で、mountしようとすると、以下のような感じになります。
何か救済案はないでしょうか。
[root]# mount /data
mount: wrong fs type, bad option, bad superblock on /dev/md2,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
[root]# dmesg | tail
