File system Corrupt

[aamak]

Hi,
i am using J5600 machine with OS 11.11.The problem is this, one file system mount name /var is corrupted and unable to mount. when I manually try to mount the /dev/vg00/lvol8 on /var the error message appear vxfs mount: /dev/vg00/lvol8 is corrupted. Needs checking. When I use fsck to repair the file system the below mention output received
fsck -o full vxfs /dev/vg00/rlvol8
fsck: /etc/default/fs is used for determining the file system type
vxfs fsck: cannot stat vxfs
vxfs fsck: file system had I/O error(s) on meta-data.
log replay in progress
pass0 - checking structural files
pass1 - checking inode sanity and blocks
vxfs fsck: fsck read failure bno = 352367, off = 0, len = 8192
file system check failure, aborting

Thanks in advance

It seems your disk drive may have failed.

Hi,

you could verify the disk.

# dd if=/dev/rdsk/cxtydz of=/dev/null bs=1024k

and wait for an i/o error.

It looks like some sectors on /dev/vg00/var might have gone bad. The right syntax to fix corrupted FS with type as vxfs is :
#fsck -F vxfs -o full -y /var

#fsck -F vxfs -o full -y (to verify all FSs with single entry).

If alternate disk is there, try booting from alternate disk.

Bsides the above-mentioned methods look in the /var/adm/syslog/syslog.log file for lbolt or SCSI errors. They are also a sign of failing hardware. You could try dmesg unless it has been overwritten due to its cyclic nature.
