file system check failure, aborting ...

[Deeos]

Hi ,


Could you do following stepsand give output once more:

#more /etc/mnttab

#mv /etc/lvmtab /etc/lvmtab.oldd

#vgscan -v

#vgdisplay -v

#vgdisplay -v vg01

#mount -a

#more /etc/mnttab


Regards
Deeos

[Deeos]

after

#vgscan -v

#strings /etc/lvmtab

Hi Bill,

I am getting the below error, while running vgimport

# vgimport -s -m vg01.map vg01
vgimport: Couldn't open MAPFILE "vg01.map".
vgimport: vg01.map: No such file or directory

Hi Bill,

came to the same stage, where we started.

# vgimport -s -m vg01.map vg01
# cd /dev/vg01
# ls
group lvol13 lvol15 rlvol13 rlvol15
lvol11 lvol14 rlvol11 rlvol14
# vgchange -a y vg01
vgchange: Couldn't activate volume group "vg01":
Quorum not present, or some physical volume(s) are missing.

# mount -a

There was a missing step. Normally, the system administrator will create map files for all the current volume groups. This must be done manually and I suspect that there aren't any map files in /etc/lvmconf.

So you'll need to create one. From your listings above, it appears that vg01 has 4 lvols numbered 11 12 13 and 14. Ans since we can see the serial number information from showLVMinfo, you can create the map file which will look like this:

cat /etc/lvmconf/vg01.map
VGID 0x68ff98134194a5e6
1 lvol11
2 lvol13
3 lvol14
4 lvol15

DISCLAIMER: I am assuming that this was the order of the lvols when they were first created. Without a map file, I am just guessing. After you use vgimport, vgchange and mount -a, you'll need to verify that the files are in the correct mount points.

Now you should be able to use vgimport:

(create /dev/vg01 and /etc/vg01/group with nothing else in the directory)
vgexport -s -m vg01.map vg01
vgchange -a y
mount -a

If the mount point names have the wrong files, make a list of which lvol has the required files for the destination mount point, then change /etc/fstab and remount the volumes.

Please post the exact vgexport command you did!

Hi Bill,

I have this file

Hi Torsten,

I have run the vgexport command as below

# vgexport -s -m vg01.map vg01

Hi Torsten/Bill,

Thanks for all the support provided. This problem is due to SCSI terminator, which was broken. I replaced the SCSI terminator. I am able to mount few lvm's which are on external storage.

Now I have the below issue. I am not able to mount /dev/vg01/lvol14 and lvol15.

vxfs mount: read of super-block on /dev/vg01/lvol15 failed: I/O error
vxfs mount: /dev/vg01/lvol14 is corrupted. needs checking
mount: /dev/vg01/lvol13 is already mounted on /oradumps
mount: /dev/vg01/lvol11 is already mounted on /tarot
mount: /dev/vg00/lvol9 is already mounted on /apps
mount: /dev/vg00/lvol8 is already mounted on /var
mount: /dev/vg00/lvol7 is already mounted on /usr
mount: /dev/vg00/lvol6 is already mounted on /opt
mount: /dev/vg00/lvol5 is already mounted on /tmp
mount: /dev/vg00/lvol4 is already mounted on /local
mount: /dev/vg00/lvol1 is already mounted on /stand

For lvol15, there is a bad spot on the disk which cannot be read. You can verify this with dd:

dd if=/dev/vg01/rlvol15 of=/dev/null bs=1024k

You can try to fix this with fsck. Run the command:

fsck -o full /dev/vg01/rlvol15

Because there is a bad spot on the disk, fsck may not be able to fix the problem. If it reports I/O errors, the disk is damaged and will have to be replaced. This means that all the data on vg01 will have to be restored from your backup tapes. To determine which disk is bad, run dd on each of the disks (will take a few minutes):

dd if=/dev/rdsk/c5t0d0 of=/dev/null bs=1024k
dd if=/dev/rdsk/c2t0d0 of=/dev/null bs=1024k
dd if=/dev/rdsk/c4t0d0 of=/dev/null bs=1024k

The second error is probably recoverable. Use a similar command:

fsck -o full /dev/vg01/rlvol14

If you don't have a backup of these lvols, don't start any applications. Instead, backup all the lvols on vg01 immediately.

Hi Bill,

please see the output as below

Hi Bill,

I have reinserted the disks.Everything is working fine now.

Thanks a lot Bill
