Hello. I have a test server that I'm messing around with, and just recently received an error on startup that a logical volume in the root volume group couldn't be re-synchronized. Server boots fine, as the root vg is mirrored, but I'd like to get rid of the error. Here are the details:

Code:

lvsync:  Couldn't re-synchronize stale partitions of the logical volume:
Device offline/Powerfailed

lvsync:  Couldn't resynchronize logical volume "/dev/vg00/lvol2"

When I run:

Code:

lvsync /dev/vg00/lvol2

I get the same error message as above.

I have isolated the stale partitions to one of the 3 disks in the volume group:

Code:

vgdisplay -v | grep "PV Name"
PV Name     /dev/dsk/c0t8d0
PV Name     /dev/dsk/c1t9d0
PV Name     /dev/dsk/c1t10d0

pvdisplay /dev/dsk/c1t9d0
--Physical Volumes--
PV Name          /dev/dsk/c1t9d0
VG Name          /dev/vg00
PV Status         available
<...snip...>
Stale PE           363

ioscan shows the disk as CLAIMED.

Do I have a disk that is going bad, or am I missing something very obvious?

Thanks in advance for any clues.

Looks like part of the disk is bad:

Code:

# dd if=/dev/dsk/c1t9d0 of=/dev/null
dd read error: I/O error
142780+0 records in
