After a hard drive failure (and no backup...) I am trying with all my
strength do recover the file systems... With no real success. I have
dumped over the two file systems in question to another, healthy disk
drive. After dumping back the data to a third hard disk, one of the
file system can be successfully mounted but with a huge number of
files in the lost+found directory (after recovery using xfs_repair).
Strange since the dump indicated only 11 bad sectors on that file
However, the big (55 gig) file system cannot even be mounted and this
is troublesome since it contains the most valuable data. This is what
I get after doing xfs_repair on the volume:
Jan 10 10:30:59 amos kernel: SGI XFS with ACLs, security attributes,
realtime, large block numbers, no debug enabled
Jan 10 10:30:59 amos kernel: SGI XFS Quota Management subsystem
Jan 10 10:31:00 amos kernel: XFS mounting filesystem sda10
Jan 10 10:31:00 amos kernel: XFS: failed to read RT inodes
The repair was done using Debian-compiled Linux kernel (2.6.17-2-k7)
using xfsprogs 2.8.11-1. Afterwards, I've upgraded the kernel to
2.6.22 and xfsprogs 2.9.4-2 but it doesn't really make much of a
I've tried to disable the realtime stuff afterwards, by mounting the
filesystem using rtdev=/dev/null but I only got the following message
out of that:
Jan 10 10:36:40 amos kernel: XFS: Invalid device [/dev/null], error=-15
*Any* ideas on how to proceed with this is greatly appreciated...
Thanks in advance.
