[linux-lvm] Weird UUIDs

[Patrick Boutilier]

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. Everything is 
working OK but I wonder if this is a serious problem or not? This is a 
single physical volume LVM running on top of hardware RAID 5.



pvdata -Uvv /dev/sda7
