| Hello, I got some more debug output from the lvchange command. I noticed, that sometimes lvchange -an vg0/daily-snap-opt worked and after that I was able to really remove the snapshot. But most of the times it doesn't work. It seems that system need several minutes do free the snapshot because when I wait some minutes an retry, I can deactivate and remove the snapshot to reuse the name. root@konrad:~# lvchange -vvv -an vg0/daily-snap-opt Processing: lvchange -vvv -an vg0/daily-snap-opt O_DIRECT will be used Setting global/locking_type to 1 Setting global/locking_dir to /var/lock/lvm File-based locking enabled.
