Hi all,
I would like to raise my problem because I have not found the answer to my
question by searching on the Internet. Hoping that one of you had experience
with this kind of problem.
I'm looking for a way to launch a script or disable an LVM snaphot before it
becomes full.
For example I would like to launch a script that will umount the LVM snapshot
and delete it if it reaches 90%. That is to avoid LVM issue when snapshot is full.
Any ideas ?
Write dmeventd plugin - similar as you can find in upstream git source tree.
BTW - what's is the point to delete it 90% and delete it when it's invalid ?
If you don't need the snapshot you should remove it instantly - since it's
impact system performance.
And if you need it - it's probably more useful to extend the snapshot.
