So after a botched package update I decided to revert to the snapshot
I took just before doing the update. After shutting guest down, I
started
lvconvert --merge vmhost_vg0/desktop_snap_20200121
and instead of seeing the usual percentage of how far it has
completed, I got nothing. lvs -a -o +devices shows
LV VG Attr LSize Pool Origin
Data% Meta% Move Log Cpy%Sync Convert Devices
desktop vmhost_vg0 Owi-a-s--- 20.00g
/dev/sdb3(14848)
[desktop_snap_20200121] vmhost_vg0 Swi-a-s--- 10.00g desktop 100.00
I see nothing when I do lsof against both the lv (lsof
/dev/vmhost_vg0/desktop) and its snapshot. dmsetup tells me:
[root@vmhost ~]# dmsetup info /dev/vmhost_vg0/desktop

Before I blow that lv up, what else should I be checking?
