回复 #5 jerrywjl 的帖子
除了pvcreate外,我还做过lvcreate操作。
已经DD备份了,现在DD出来的盘上做。
FSCK找不到超级块,用mkfs.ext3 -n /dev/sdg命令可以看到超级块再这些位置:
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968,
102400000
仍然有下面提示,mount不了
[root@taurus ~]# mount -o sb=20480000 /dev/sdg /test2
mount: you must specify the filesystem type
[root@taurus ~]# e2fsck -b 20480000 /dev/sdg
e2fsck 1.35 (28-Feb-2004)
e2fsck: Bad magic number in super-block while trying to open /dev/sdg
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> |
