Hello,
I had created snapshot of my /var logical volume a while ago and recently It occured to me that I don't need saved state anymore and I would like to reclaim disk space. But I have issued wrong lvconvert --merge command by mistake instead of proper lvremove.
$ sudo lvconvert --merge VolGroup00/var_snap0
Can't merge over open origin volume
Merging of snapshot var_snap0 will start next activation.
I have figured out at this point that I made mistake. Luckily merge is postponed as volume is used (mounted) now. But how do I prevent merge from running upon next reboot? Here is what I have tried:
$ sudo lvremove VolGroup00/var_snap0
Can't remove merging snapshot logical volume "var_snap0"
$ sudo lvchange -an VolGroup00/var_snap0
Change of snapshot var_snap0 will also change its origin LogVol01. Proceed? [y/n]: n
Logical volume var_snap0 not changed.
I even could not create snapshot of current state to roll back to it after merge
$ sudo lvcreate --size 2G --snapshot -n var_snap1 /dev/mapper/VolGroup00-LogVol01
Snapshots of an origin that has a merging snapshot is not supported
Is there a way to cancel postponed snapshot merge?I had created snapshot of my /var logical volume a while ago and recently It occured to me that I don't need saved state anymore and I would like to reclaim disk space.
