Helo,

today I can't mount the software raid partition /dev/md2.

The raid device is configured throught this disks:
/dev/sdb4, /dev/sdc4, /dev/sdd4

Disk /dev/ssd4 is OK, disc /dev/sdc4 is marked as spare (why ??) a /dev/sdb4 couldn't read the superblock. I don't know why is the /dev/sdc4 marked as spare disc. I can't start array and download the data.


gate:/media# cat /proc/mdstat
