how can i force a sync on stale partitions?

[mobidyc]

Hello,

i've replaced a bad disk today but when i try to re-sync those LE/PE, i can't :
# lvsync /dev/vg00/lvol1
lvsync: Couldn't re-synchronize stale partitions of the logical volume:
I/O error
lvsync: Couldn't resynchronize logical volume "/dev/vg00/lvol1".

i've tried to remove the disk from the vg for doing on it a pvcreate but it's not possible without restart the server because this disk is seen as used by /dev/vg00/swap_2...and it's not a mirror ;(

is there a way to force the synchronisation ?
maybe by doing a dd command?

thanks for help.

Hi,

I don't know what steps you did, but the message
"I/O error"
looks like a hardware problem.
BTW, an unmirrored swap is not a good idea ...

Perhaps this document can help you:

Hello,

i've already seen the document and the first step is to halt lvm access to the disk, a thing i can't because of the non mirrored swap volume.

i know that a no mirored swap volume is a problem, if i had seen it before the problem would be gone.

Hi Cedrick,

I dont think you have any other choice than reboot, have you checked the disk for any bad blocks ?

Are diskinfo,ioscan and dd commands working fine and are there any error messages ?

Have you tried to check if the disk has been found by lvm using pvdisplay ?

hi,

post the steps you have done so far.

Also what was on the disk? is it a secondary swap disk?


Also?

# lvsync /dev/vg00/lvol1
lvsync: Couldn't re-synchronize stale partitions of the logical volume:
I/O error
lvsync: Couldn't resynchronize logical volume "/dev/vg00/lvol1".

lvol1 should be /stand?

so when are you issuing in this command?

post your lvdisplay if you can, or part of.

Also post ioscan if you can? was the disk replaced a hotplug disk and done while server up and running?

Hello,

the disk was changed so, i've needed to export the bad/missing disk informations from lvm for doing a pvcreate on the new disk...(that seems to be stupid for me).

by error (or stupidity), the secondary swap space was not mirrored like others lvols but concatened, it was impossible to remove the disk from the vg.

after a reboot and recreate the secondary swap space, all seems to be fine now.

thanks all.
