Я удалил два диска (sda1 и sdb1) из мягкого массива RAID1.
mdadm --stop /dev/md0
mdadm --remove /dev/md0
mdadm --zero-superblock /dev/sda1
mdadm --zero-superblock /dev/sdb1
Выход mdadm --examine /dev/sdb1
root@rescue:~# /mnt # mdadm --examine /dev/sdb1
mdadm: No md superblock detected on /dev/sdb1.
я пытался сесть /dev/sdb1 to /mnt
mount /dev/sdb1 /mnt -t auto
mount: you must specify the filesystem type
mount /dev/sdb1 /mnt -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
(/ dev / md0 был ext4)

fsck /dev/sdb1
fsck from util-linux 2.20.1

ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb1
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
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>
or
e2fsck -b 32768 <device>
я хочу смонтировать с существующими данными (sdb1 или sda1). любое решение? у меня есть важные данные.
