Manually remove snapshot

[frantek]

Hi,

on a LVM setup I did some thing stupid. I manually (edit conf file ...) added LVM disks of VM A to VM B. Now VM B is in production and I've noticed that there is a snapshot on VM A.

My question is: Can I safely use "lvremove" to remove the LVM snapshots?

I think the answer is: yes ... but, it's a production system

TIA
Matthias

Hi,

Thin-LVM every snapshot is independent,
so yes you can do it without problems.

I think the answer is: yes ... but, it's a production system

But if you unsure make a test VM and test it before ;-)

Did so already

When you look, at my last post - it IS "Thin-LVM" and removing the snapshot is no problem, right ?

Yes correct.
