Hello,<BR>
<BR>
I wanted to get some help about LVM2 snapshots, but I'm not sure where to ask.<BR>
<BR>
I'm using LVM2 with KVM instances, it works great. I then wanted to play a little bit with the LVM snapshot merging facility, as long as the VM is powered off it works perfectly, but when I tried with a powered on VM I ran into troubles. The merging did not start and is now stuck :<BR>

I would like to delete the snapshot and recover the original volume.<BR>

I will be very happy if someone could give me some hints or redirect me to the right place for asking for help.<BR>
<BR>
Thanks.<BR>
