Re: can't mount raid 5 after installation

[kohzak <kohzak@gmail.com>]

So, i've wait until it finish to create the raid.


# cat /proc/mdstat
Personalities : [raid5]
md0 : active raid5 sda1[0] sdd1[3] sdc1[2] sdb1[1]
      480238656 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]

But same problem after rebooting :

$ dmesg | grep md
md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27
md: md0 stopped.


# mount /dev/md0
mount: /dev/md0: can't read superblock
