 |
|
I am having trouble rebuilding my raid array after putting my computer into a new case.
| Code: | UmHelp chris # mdadm --assemble /dev/md0 /dev/sdc1 /dev/sde1 /dev/sdf1
mdadm: cannot open device /dev/sde1: No such file or directory
mdadm: /dev/sde1 has no superblock - assembly aborted |
It isn't building because the /dev/sde1 & /dev/sdf1 do not exist.

I guess my problem lies with the "sde: unknown partition table" with sde and sdf??? Anyway to fix this so I can get my data off?

hi!
according to the output of "dmesg" i think, your hardware is available (sde and sdf are physically available). You posted that you put your computer in a new case. did you plug in the harddrives to the former sata connectors?? this could be a reason for the "/dev/sde1 has no superblock" message.
you could also check if the partition is still there with

Bit of a longshot, but did you really use sd[ef]1 partitions for the array and not the actual raw block device?
try running
| Code: | | mdadm --examine /dev/sd[ef] |
Cheers

Yea the partitions are shot.
| Code: | Command (m for help): p

255 heads, 63 sectors/track, 91201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

1465149167 unallocated sectors
|
Their should be partitions there. When I was making the array I did use partitions on the drives. Can I recover the partitions somehow without wiping my data? |

hi um_help!
your partition table is corrupted. try the "gpart" utility. there is an option to guess the partitions. perhaps it fixes your problem.
you can also try this link http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/Partition-Rescue.html#AEN107 - it might help you but its very old...

I am running gpart on one of my disks it looks like its gonna take a few hours so I will post my results with its done. If only my smaller drives got corrupted  750gigs takes forever to scan.
Thanks for the help  |

Begin scan...
End scan.
Checking partitions...
Ok.
Guessed primary partition table:
Primary partition(1)
type: 000(0x00)(unused)
size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r
Primary partition(2)
type: 000(0x00)(unused)
size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r
Primary partition(3)
type: 000(0x00)(unused)
size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r
Primary partition(4)

size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r |
I don't really know exactly what this means but it doesn't look to promising. What can I do with this now?
Here is what I get from the working drive:
| Code: | UmHelp chris # gpart /dev/sdc -vd

Here is the output from the other broken drive:

When I first built this RAID I only used one XFS partition that covers the whole drive. |

| Fixed my problems. I re-wrote the partition tables with fdisk and set the partition type to fd and mounted and so far everything works great. |
