Hi,

There may be a bad block in your harddisk on which /dev/vg00/lvol10 is there.

hence this error in syslog.log

Check these things:

1.Run lvdisplay -v /dev/vg00/lvol10 and see for any stale extents are there.

2.Check with bdf if you have sufficient space on thie file system,

The last time I experienced this error I had a bad disk drive. Try doing a "diskinfo" on the disk that contains lvol10.

Hi,

You can run this command if you want to check any errors in your harddisk. If the input and output no of the command is same then there are no bad sectors in the harddisk or else you may have to change the harddisk since it is on the root filesystem.

dd if=/dev/rdsk/c1t2d0 op=/dev/null bs=1024k

Hi,

Sorry a mistake in the command :of instead of op

dd if=/dev/rdsk/c1t2d0 of=/dev/null bs=1024k

if=root harddisk ( raw device file )

This may also be caused by by a faulty volume group what is the o/p og vgdisplay -v /dev/vg00
and also what is the o/p of dmesg .

You have a bad spot on the disk or a failing disk. Your choice is to continue to use it and hope it is localized. However, you should call service and have it replaced if necessary. Once you have replaced the disk fix your VG and restore your data.
