Hi.
Since I have tried to fix the problem for a few day, but I Couldn't . I
wrote it briefly below.
------------------------------------------------------------------------------------------------------
1.detect the problem
[root@localhost mntb]# mount -t xfs /dev/hdd1 /home/lss1/lssmnt/mntd
mount: wrong fs type, bad option, bad superblock on /dev/hdd1,
or too many mounted file systems
[root@localhost mntb]#
-------------------------------------------------------------------------------------------------------
2.the trials to rescue this disk
=========================================================
Spec:
Model: WDC WD1800JB-00DUA0
filesystem type: XFS
capacity: 180G
My system: RED HAT 9(kernel:SGI 2.4.20-09XFS)
=========================================================
I'm useing this disk for backup disk. Abosolutely it contains very important
files to me.
---------------------------------------------------------------------------------------------------
* In redhat, I check the "hardware browser".
Results:
/dev/hda
hda2 1 255 2000M linux-swap
hda1 256 9733 74348M xfs /
/dev/hdb
hdd1 1 21889 171703M NO filesystem(*)
(*) why does the XFS partiions(hdd1) remove? it's originally used in XFS.
I didn't format this one.
--------------------------------------------------------------------------------------------------
To rescue one. I did it like below. it doesn't work.
I don't know exactly why this happens abruptly?
-------------------------------------------------------------------------------------------------
[root@localhost sbin]# ./xfs_repair /dev/hdd1
Phase 1 - find and verify superblock...
superblock read failed, offset 0, size 524288, ag 4294967295, rval 0
fatal error -- Input/output error
[root@localhost sbin]# ./xfs_repair /dev/hdd
Phase 1 - find and verify superblock...
superblock read failed, offset 0, size 524288, ag 4294967295, rval 0
fatal error -- Input/output error
[root@localhost sbin]#
------------------------------------------------------------------------------------------------
* another ways to rescue this disk.
1.partition-rescue-mini-howto.
it's not helpful. it's useless to rescue original XFS filesystem.
2.SGI FAQ and Mailing list Archives.
There is also no similar case.
Around Mar 2003, I have a problem to use XFS. At that time, I report the
problem to the XFS team. Through a few communications with xfs team. At
that time,I decided there is no bugs in XFS but,the physical harddisk.
This case definitely has no problems of this physical hard disk.
*is there anyway to repair the corrupted xfs filesystem even if it costs ?
*do I have to format this disk?
thanks.......
