Good day!

After unexpected energy shutdown my WD ShareSpace 4Tb doesn’t work properly.

All disks are OK:

i’m trying to repair RAID10 (md2, md3), but i suppose, it’s current configuration isn’t right (look below: there isn’t information about RAID10):

~ $ cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid5]
md2 : active raid1 sda4[0]
      975146112 blocks [2/1] [U\_]

md1 : active raid1 sdd2[3] sdc2[1] sdb2[2] sda2[0]
      1044160 blocks [4/4] [UUUU]

md3 : active raid1 sdd4[1]
      975146112 blocks [2/1] [_U]

md0 : active raid1 sdd1[3] sdc1[2] sdb1[0] sda1[1]
      208768 blocks [4/4] [UUUU]

unused devices:

I neen relults of cat /proc/mdstat from same device (with RAID10) to compare it.

Could sombody post it here or send it me by email?

Thanks, Sergei.

Had any luck with this? o.o

Hi.

Yeah, i’ve solved my problem by repairing lvm (look this article - http://www.linuxjournal.com/article/8874?page=0,0). Fortunately, data on a RAID parts (and RAID config) was OK, and i’ve just combined it.

Best regards, Sergey
