Hi, Just noticed this one. [root at slippey /root]# lvcreate -l5 -s snap /dev/vol/foo Segmentation fault (core dumped) Haven't looked at it much, off to a meeting now (sigh), but it appears to be a simple option parsing problem when using -s. A proper command for that to work would be: lvcreate -l5 -s -n snap /dev/vol/foo
