[linux-lvm] Question re: deleting an LV...



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?

Thanks
