質問です。
環境：CentOS5.3、WD10EADS (1TB,32MB) 5台でmdadm(RAID5)
不良セクタをチェックしようと、以下のコマンドを実行しましたが、エラーが出ます。何か足りないのでしょうか。
e2fsck -b 8193 /dev/sdc1を実行してもダメでした。
[root ~]# e2fsck -c /dev/sdc1
e2fsck 1.39 (29-May-2006)
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sdc1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
