Well, currently there are some minor glitches. I just installed a vinum slice on /dev/ar0s1 and unless I do a 'vinum read /dev/ar0s1' vinum will not find the volumes. This causes the boot of my box ( -current btw) to fail at the mount of my filesystems. Is there a way to tell vinum to also look on /dev/ar* for its config ??
