Re: [linux-lvm] Weird UUIDs

I tried running pvdata -U on one of my LVM servers and it segfaulted (LVM driver version 0.9.1_beta6). Check out the UUIDs.

Output just tells you, that no UUIDs have been created dynamically so far. If you create/remove a dummy LV, they should be there...

Everything is working OK but I wonder if this is a serious problem or not?

No, it is not. Just try the lvcreate/lvremove pair on a small (-l 1) dummy LV.
