Hello, You were right Wol. Only one of the disks was damaged. I reinstalled the 5 drive plus a new one and started the system. I copied the partition table from one drive to the new drive and then added the partitions to the 2 arrays. The recovery has started. It seems to be almost all right. On raid 10 array md1 is a Xen Storage, and some VMs that have XFS file system, booted up but report errors like "XFS (dm-2): Internal error XFS_WANT_CORRUPTED_GOTO". But this is probably the subject of another discussion... Thank you all for your support and advices. Cheers, Liviu
