Would appreciate a confirmation that I don't have to do anything else to
totally eliminate the snaps LV...
I unmounted it, and commented that line in fstab. lvscan still shows the
same as above, but lvs shows the snaps with a slightly different attribute:
LV VG Attr LSize
log vg -wi-ao---- 5.00g
snaps vg -wi-a----- 4.00g
tmp vg -wi-ao---- 5.00g
var vg -wi-ao---- 700.00g
vtmp vg -wi-ao---- 5.00g
So again - is lvremove /dev/vg/snaps the correct way - and the only
thing I need to do - to remove that LV as if it had never been created?
