I recent this mail to the list so that archive are complete.
And I'm adding answer to a question you asked me about sending
you the kernel message when I try to mount the drive.
Here is the dmesg output ( I stripped everything that's related to booting)
FAT: bogus logical sector size 28783
VFS: Can't find a valid FAT filesystem on dev 03:41.
SGI XFS 1.3.1 with ACLs, no debug enabled
SGI XFS Quota Management subsystem
XFS: bad magic number
XFS: SB validate failed
The FAT & VFS message is related to when I try to mount the drive
without specifying the filesystem type. ( mount -t xfs )
Hi, im new to xfs never used it personnaly but
the other day I realised that our Linksys EFG80 NAS
was working on xfs filesystem
Hm, very interesting... :)
My problem is that the drive in this NAS has been corrupted
in someway, and I would like to salvage data on this drive.
So I put the drive in a Linux machine, installed the XFS kernel
supplied of oss.sgi.com web site. But when I try to mount the drive
mount -t xfs /dev/hdb1 /mnt/nas
Just to be sure, how do you know it's really xfs on-disk?
The unit is composed of two disk, the second one didn't fail and I was able
to mount the drive and use it with XFS. And before I installed the XFS
enabled kernel, when I tried to mount the drive I had the error message:
mount does not support XFS filesystems
I get these errors:
XFS: bad magic number
XFS: SB validate failed
mount: wrong fs type, bad option, bad superblock on /dev/hdb1
or too many mounted filesystems
try "dmesg' to see what kernel messages may have come from
the failed mount.
Is there a way for me to restore this drive, is there any utility that
can be downloaded to restore this drive?
Ask linksys... ;-) if it's really xfs, and they haven't munged
it too much, you could try xfs_repair. (with -n to do a dry run
first)
HAHAHA when I contacted live support at Linksys, they were unable to tell me
the exact type of filsystem used on their device, they could only tell
me it was a Linux based system, so a linux based filesystem.
