We want to have 2 filesystems on our lustre setup (1 MDS, 1 OSS, version 1.4.6): 1. Must this setup use only 1 xml-file? If so, in the case of adding another filesystem to an MDS/OSS that already has 1 filesystem configured, is it possible to create (lconf --reformat) the new filesystem without destroying the existing filesystem? 2. One option that we haven''t tested is to create a new xml-file for the second filesystem, do a lconf --reformat on that one, and later create a single xml-file for both filesystems and restart the lustre-service using this single xml-file without --reformat. Do you think this will work? 3. If we must keep separate xml-files for each filesystem, then we must modify /etc/init.d/lustre for this - has anybody done such a modification (e.g. such that doing /etc/init.d/lustre stop does not issue a --cleanup until all other filesystems have been stopped, etc.)? thanks for any help, Per Lundqvist -- Per Lundqvist National Supercomputer Centre Link?ping University, Sweden http://www.nsc.liu.se
