Hi,

I am using LVM2 for some time now and haven't had any troubles.
But this week one of the hard disks, the one I added approx. one month ago, started to report read/write errors.
I bought a new one and followed the steps of an LVM how-to found on this website (http://charlesnadeau.blogspot.com/2006/10/howto-replaceupgrade-disk-part-of-lvm2_04.html).

The first steps worked fine. Even shrinking the reiser file system was no problem.
But when I tried to pvmove /dev/hdb1 /dev/hdf1, I am getting the error message: Can't resize locked LV lv.

As there is no available information about what this error message actually means nor how to resolve it, I hope someone on this list might be able to help me.

Thank you very much in advance.

Cheers Christian

PS: this is my current configuration. where hdb1 is the failing hdd, and hdf1 the new one.

Re: [linux-lvm] LVM2 Problem Can t resize locked LV lv

Let me extend my previously posted message, as I mixed up some error messages: here are the correct ones:

# lvreduce -L -150G /dev/vg/lv
 Can't resize locked LV lv

# pvmove /dev/hdb1 /dev/hdf1
 Skipping locked LV lv
 No data to move for vg

Anyways I am still looking for an answer what "locked" means and how I unlock the logical volume.

I am using gentoo with kernel 2.6.17-gentoo-r8.

Once again, thank you for your help in advance

Cheers
Christian

Re: [linux-lvm] LVM2 Problem Can t resize locked LV lv

just got the solution over irc.
i post it in case anyone else encounters this strange behaviour.

i need to mention first that pvmove was not running (checked using lvs -a), so this is kind of a stange behaviour.

to fix the "locked" error, you first need to deactivate your lv

# lvchange -an /dev/vg/lv
then edit your vg backup (/etc/lvm/backup/vg) and remove "LOCKED" in the lv status line.
after that do
# vgcfgrestore vg
# lvchange -ay /dev/vg/lv

when doing lvreduce now, everything should work properly.

big thanks to the guys on #lvm.

cheers
