Switched to 'tur' in multipath.conf. Same behaviour. :( Curious - are the Mike Christie patches (which I should avoid) in the 2.6.9-udm1.tar.bz2 patch set? Also, in /v/l/messages, I'm seeing stuff like: Nov 29 17:16:56 nfstest1 kernel: device-mapper: : dm-multipath: invalid number of paths Nov 29 17:16:56 nfstest1 kernel: device-mapper: error adding target to table Is this normal? I'm leaning more towards device-mapper being faulty.
