Hi,
some time ago I created a new LVM volume inside a LVM pool and did not
allocate the full volume size initially.
Because of that Virt-Manager additionally created a snapshot for this
volume.
How can I get rid of this snapshot? Can I just remove it with lvremove?
Or will there be some side effects?
The volume data are:
--- Logical volume ---
LV Path /dev/vg0/mine-mx0
LV Name mine-mx0
VG Name vg0
LV UUID Drydli-ecto-FGym-xwlM-8uMe-gDdp-xHskio
LV Write Access read/write
LV snapshot status active destination for mine-mx0_vorigin
LV Status available
# open 1
LV Size 150.00 GiB
Current LE 38400
COW-table size 98.83 GiB
COW-table LE 25300
Allocated to snapshot 53.19%
Snapshot chunk size 4.00 KiB
Segments 2
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 252:15
I believe if you request a not-fully-allocated lvm volume, then libvirt asks
lvm to create a 'thin volume'. But that's the extent that I know, so
maybe try
googling 'lvm thin volume' for more info.
Thanks, I think that's going to lead me into the right direction.
