FWIW,
posting the way to stop a merge, (given that no one else seemed
to have the answer)... removed the 'uninteresting vg/lv's...
Home still merging:
# lvs --all -o lv_name,lv_attr,origin
LV Attr Origin
Home Owi-ao
[Home-2011.09.03-00.28.36] Swi--- Home
Since the device for the snapshot was gone (dmsetup removed it),
the only place it seemed to be stored on disk was
the on-disk VolGroup table...so...lets fix that!
Find right backup...
# vgcfgrestore -l Home+Space
File: /etc/lvm/archive/Home+Space_00199.vg
VG name: Home+Space
Description: Created *before* executing 'lvconvert --merge \
/dev/Home+Space/Home-2011.09.03-00.28.36'
Backup Time: Sun Sep 11 17:29:56 2011
Restore:
# vgcfgrestore -f /etc/lvm/archive/Home+Space_00199.vg Home+Space
Restored volume group Home+Space
# lvs
LV VG Attr LSize Origin
Home Home+Space owi-ao 1.00t
Home-2011.09.03-00.28.36 Home+Space swi--- 1.00t Home
# lvremove /dev/Home+Space/Home-2011.09.03-00.28.36
Logical volume "Home-2011.09.03-00.28.36" successfully removed
Didn't even have to use "-f" on the lvremove...
Hey, seems like it's the only way to stop a merge (?)
