hi Guys,

I hope you are able to help me, because i think that i
tried everything that i know off to repair my raid after a disk failure.

Systemspecs:

   - HP N40L
      - CPU: AMD Turion II @ 1,5GHZ
      - 8GB ECC RAM
      - Disks:
         - 250GB | OS
         - 4x2GB | RAID 5 | Softraid
      - OS: Openmediavault @ 3.0.20 (last version)


Problem:

In my raid a disk was fault so mdadm kicked the disk out of the raid. I put
a replacement in the box and started a resync of the raid and than
is happened, a second disk got lost in the raid. The raidsync wasn't
finished and now i'm fighting 3 weeks or more i don't no any more :-( to
repair the file system.

I tried a lot of different versions of xfs_repair (2.9.4, 2.9.8, 2.10.2,
3.0.4, 3.1.2, 3.1.6, 3.1,8), but every precompiled version got an
"segmentation fault" or hung at phase 3 with 100% cpu load for few day. I
also tried different distros like ubuntu, debian, redhat, gentoo (yes, i'm
a little bit desperate :-) )  Than i tried the git version and at first it
looked good but than i got an another error but i don't understand what the
problem is.

tried options without any luck: xfs_repair -v -P | xfs_repair -v -P -m 6144
| xfs_repair -v -P -L

Metadump of the filesystem isn't possible at this moment, but i could
bootup a live cd and give it a try with it. I'm pretty stuck and don't no
what to do any more.


with kind regards
Veli
