Here's what I've done: [root@athena root]# mount | grep iso2 (no output - volume iso2 is not mounted) [root@athena root]# vinum vinum -> stop iso2 vinum -> lv iso2 V iso2 State: down Plexes: 2 Size: 1500MB vinum -> rm iso2 Can't remove iso2: Device busy (16) vinum -> stop iso2.p0 vinum -> stop iso2.p1 Can't stop iso2.p1: Device busy (16) vinum -> ls iso2.p0.s0 S iso2.p0.s0 State: down PO: 0 B Size: 1500 MB vinum -> ls iso2.p1.s0 S iso2.p1.s0 State: up PO: 0 B Size: 1500 MB vinum -> stop iso2.p1.s0 Can't stop iso2.p1.s0: Device busy (16) I don't appear to be able to stop the other half of the mirror in order to be able to successfully rm the volume and the plexes. I haven't tried the -f option due to dire warnings in the man page ;-) My current train of thought is that the mirror is still "active" in some sense, and thus vinum is protecting the mirroring when I want to stop both halves of it. The manual says "By default, vinum does not stop active objects." However, I don't know what would be making it active - it's not mounted and I seem to be unable to stop all of the volumes subordinate objects. > > Are there any potential pitfalls involving dataloss? > > You'll lose all data on iso2. That's fine, it was volume iso I was worried about. Thanks for sharing your time, -T -- "...you could spend *all day* customizing the title bar. Believe me.
