Syslog || /var/log/messages is the normal place. You can use 'lctl ping' to verify that the client can reach the server. Usually in these cases, it's a network/name misconfiguration. Run 'tunefs.lustre --print' on your servers, and verify that mgsnode= is correct. cliffw > > Thanks, > CS. > > > > > On Tue, Jun 16, 2009 at 12:16 PM, Cliff White <cliff.wh...@sun.com > <mailto:cliff.wh...@sun.com>> wrote: > > Carlos Santana wrote: > > Thanks Kevin.. > > Please read: > > http://manual.lustre.org/manual/LustreManual16_HTML/ConfiguringLustre.html#50401328_pgfId-1289529 > > Those instructions are identical for 1.6 and 1.8. > > For current lustre, only two commands are used for configuration. > mkfs.lustre and mount. > > > Usually when lustre_rmmod returns that error, you run it a second > time, and it will clear things.
