vxfs file system error.

VINU — Mon, 27 Sep 2004 00:25:40 GMT

Hi All,
I got the following message in syslog,

Sep 23 23:03:00 suboz014 vmunix: vxfs: mesg 055: vx_metaioerr - /dev/vg02/lvol1 file system meta data read error

Sep 23 23:03:00 suboz014 vmunix: vxfs: mesg 003: vx_mapbad - /dev/vg02/lvol1 file system free extent bitmap in au 68 marked bad,

Could anyone tell what does this mean exactly.

Regards

VP

Hi VP,

This may most probably be related to problems on underlying physical disk. What I would is to immediately take a good backup of this filesystem if possible.

Then see if there are any problems with the disk(s) containing the LV. 'lvdisplay -v /dev/vg02/lvol1' will show you the disks. Look for lbolt/POWERFAILED errors in dmesg and syslog.log. Run ioscan -fnC disk and make sure these disks are in fact claimed. Run dd to ensure that there are no IO problems with the disk

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

If there is a problem with the disk, then you will need to fix it. Once you have the backup, then unmount the filesystem and do a full filesystem check

fsck -y -o full /dev/vg00/rlvol1

Vinu
This is the media problem with the disk.You need to replace the disk at the earliest.
