Hello,
Due to a misunderstanding about how LVM snapshots work when I set up
this system, I now need to delete an LV I had created to use for this
purpose (I thought I had to pre-create the LV).
Currently I have:
# lvscan
ACTIVE '/dev/vg/tmp' [5.00 GiB] inherit
ACTIVE '/dev/vg/log' [5.00 GiB] inherit
ACTIVE '/dev/vg/vtmp' [5.00 GiB] inherit
ACTIVE '/dev/vg/var' [700.00 GiB] inherit
ACTIVE '/dev/vg/snaps' [4.00 GiB] inherit
I just need to delete the /dev/vg/snaps LV, so that that 4GB is
available for my LVM snapshots.
Am I correct that all I have to do is:
# umount /dev/vg/snaps
# lvremove /dev/vg/snaps
Then remove this line from fstab?
This would then result in my VG having 4GB available for taking LVM
snapshots?
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:
# lvs
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?
Thanks
