Stale Mirror disk

[Norville Cole]

I can not sync /dev/vg00/lvol3. and when I tried to add a new disk I was unable to due to other errors.

The error message

# lvsync /dev/vg00/lvol3

lvsync: Couldn't re-synchronize stale partitions of the logical
I/O error
lvsync: Couldn't resynchronize logical volume "/dev/vg00/lvol3"

Hi Norville,

Have a look at this doc.

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

Otherwise try to give a more detailed description of your problem.

you could have a possible failing disk.Need to identity if the source or destination is having the problem.

lvdisplay -v would give the disks involved.
do diskinfo/pvdisplay to see how does each disk response.Also take a backup of existing /etc/lvmconf.vg00.conf and issue a "vgcfgbackup vg00" it can tell you if there is any LVM corruption.

Is that the only LV effected.?

Hi,
thanks for the link it gave me a lot of good information.
Here is what I have been able to find out to date. I am mirroring a root disk.

# lvdisplay -v /dev/vg00/lvol3 |grep stale
LV Status available/stale
0036 /dev/dsk/c0t6d0 0148 stale /dev/dsk/c0t5d0 0148 current

There is only one stale condition on the booted disk. I was thinking to reboot onto the alternate disk and try to resync. Is there any gotcha's I should look out for?

thanks again
Norville
