From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030619 Description of problem: If you specify a raid block device as the physical volume to use for a logical volume to be created, it fails. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Set up a volume group say VG00 containing at least one physical volume that is a raid device say /dev/md0, with at least one free logical extent 2.lvcreate -n test -l 1 VG00 /dev/md0 Actual Results: lvcreate -- couldn't read physical volume "/dev/md0" Expected Results: It works for non-raid physical volumes (say /dev/hda5), so it should work for raid devices too. Additional info: This has been broken since at least Shrike.
Does running: lvcreate -n test -l 1 VG00 with /dev/md0 in the VG00 group work?
Yup. And even if there were only raid devices in the volume group, it would still work. It doesn't seem to be a problem with using raid devices or allocating blocks to them, it's probably more of a matter of handling command-line arguments.
