vgsync or lvsync the logical volume.

Hi,

try vgdisplay -v vg01

This will give you the list of LVs in stale. This may be b'cos of a disk failure. Get it repladed.

Susee,

It seems you have a bad disk.

register a case with h/w vendor (HP). They will replace the disk and then do vgcfgrestore on new disk.

Hi Susee,

If you have any disk failure, do the following ..

# dd if=/dev/rdsk/cXtYdZ of=/dev/null bs=64K count=1000

Hi ..

I find One of My disk is having bad sectors..
Which is in the Volume group

But is there any option to fix it & what is the use of vgsync command

[Mridul Shrivastava · Accepted solution]

when disk is replaced then to remirror the vg vgsync is used....( after executing vgcfgrestore)...

Since the disk has developed bad sectors that is the reason it is showing stale extents so replacing the disk is the only way out to oversome from this issue..

The option to fix the bad sectors is to replace the bad disk with the bad sectors on.

After replacing and restoring the LVM configuration, vgsync will copy the data to the new drive, it is synchronizing the mirror.
