Hi,

Can you do a :

dd if=/dev/dsk/c?t?d? of=/dev/null bs=4048
of the disk that contains the lvolinfo. To see the disk do lvdisplay -v /dev/vg03/lvol1.

Just to make sur ethe disk is not dead.

Hi,

Most likely there is a physical problem with the disk holding this logical volume.

Find out the PV by doing an 'lvdisplay -v /dev/vg03/lvol1' and do a dd on it to see if there are any problems.

dd if=/dev/rdsk/cxtydz of=/dev/null bs=64k

See if you get any IO errors. If so, then it is a bad disk and you will have to restore data from your backups after replacing the disk.

Also look at /var/adm/syslog/syslog.log for more errors.

You can run another pass of fsck - it's not uncommon for several passes to be required to fix an FS, BUT in this case it appears you may have a bad spot on the disk that cannot be realloctaed - block # 290 in this case.

Try another pass or that dd command to verify whether the disk needs to be replaced.

Rgds,
Jeff

Hi,

What you can do is run the fsck again on the raw lvol. If it works you might want to run mklost+found after you mounted it.
If this does not work i see no other option but to create a new filesystem and restore a backup.

DO you hava any idea what coused this ( a crask?)

Hi,

Is this logical volume only one one disk?. Can you post the output of

'lvdisplay -v /dev/vg03/lvol1|awk '/dsk/ && /current/ {print $2}'|sort|uniq

If it is only one disk and if the dd is successful, then there is a good chance that the filesystem got corrupted and you may have to end up doing a 'newfs' on it and restore the data.

Can you show me how to run fsck on the raw logical volume and what to do next?
I need to try all the options..

the disk also belongs to another logical volume ...this volume has 2 physical volumes and 2 out of 3 mount ok...that is lovl2 and 3 except lovl1 ...

thanks again for your help

Sorrie it took a while to answer but i needed a good nights sleep.

To fsck the rlvol just change the lvol into rlvol so:

fsck -F vxfs -o full,nolog /dev/vg03/rlvol1

The dd indicated that there were no problems on the disk so the other lvols are not effevted if you need to issue an newfs and a restore on lvol1.

HTH,

Gideon
