i was working with lvm on Debian that i make this mistake :
i made snapshot of my lv (suse-root) and make lv(suse-root) inactive and then run this command for merging :
# lvconvert --merge /dev/yourevg/snappy
but after runnig above command when i want to active lv(suse-root) again it gives me this error :
# lvchange -ay yourevg/suse-root
Can't expand LV suse-root: snapshot target support missing from kernel?
it explain every thing. my kernel lack of support for merging since it's "Linux debian 2.6.32-5-686" and merging future added in version 2.6.33.
so think that it's not possible to update my kernel. can any one guide me how to cancel merging ?
