The bad news is that now my BIOS is insisting my RAID is "degraded" and I am at a loss as to how to make it happy again. After wrestling with Error messages during bootup, despite what otherwise seemed to be a perfectly functioning RAID1 setup, I resorted to disconnecting each of the drives and booting off of one drive in turn to ensure things were in fact behaving properly. I am in a similar situation as this gentleman. I tried removing one disk and contiunue working with the other one and after a while pluging it again, but they don't get synchronized. I've mounted a fakeraid in Mirroring mode (raid1) in ubuntu 8.10 using dmraid.
Softraid how to replace a disk serial numbers#
Is there some file that contains the serial numbers of the dmraid softraid array? Can I just open vm and edit a config file to replace the serial number of the old member with the new one and then mount the raid array again? Or is there some esoteric commandline string I can use to specify which members of the array should be booted? I checked man dmraid but it seems impenetrable.ĭoes anybody have any suggestions for me? I am convinced that I still have all the data on both drives, the only thing keeping me from booting the raid array is that the serial numbers don't match the old array. An mdadm device would be /dev/md0 or something like that. I am convinced that dmraid was what was used because of the naming convention for my raid device it was named /dev/mapper/via_alsidss.

There is no option in the raid tool dialog to replace a member of the array with another one. I guess it looks at serial numbers rather than the actual data on the drive. Using ddrescue I copied all but 140 kb onto the new drive, but now I am lost! The Via Raid Tool says that there is a missing member of the raid0 striping array, even though there is a copy. I had a failing raid0 array from a soft raid setup using the "via raid tool", on two sata drives on my motherboard.
