cool, thanks! I tried to nail down the problem a bit more: 1. booted the system with break=mountroot 2. manually executed /scripts/local-top/iscsi. I get the two iscsi devices /dev/sda and /dev/sdb (plus all the partitions) as expected. I /dev/disk/by-uuid there are symlinks to the /dev/sdbx partitions. So far everything is as expected. 3. I manually removed the symlinks in /dev/disk/by-uuid (although this is probably not necessry). 4. manually executed /scripts/local-top/multipath. This re-creates the same symlinks in /dev/disk/by-uuid, again pointing to the /dev/sdbx partitions, instead of pointing to the /dev/dm-x partitions cheers, -- Hanspeter Kunz University of Zurich Systems Administrator Department of Informatics Email: hk...@ifi.uzh.ch Binzmühlestrasse 14 Tel: +41.(0)44.63-56714 Office 2.E.07 http://www.ifi.uzh.ch CH-8050 Zurich, Switzerland Spamtraps: hkunz.bo...@ailab.ch hkunz.bo...@ifi.uzh.ch --- To err is human, to forgive unusual. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
