(I buried this question in another post before the holidays and it didn't seem to get any response, so I'm trying again. System: 2 IBM Xeon blades as NFS/DRBD log servers setup as Primary/Secondary. 20+ Blades running various packages (JBoss, Jabber, Postgres, etc) logging to the NFS log server. All blades running RH 4 ES. Right now I have all of my processes connecting to the Primary side of a my DRBD setup. I'm using this setup as a log server for processes on multiple blades on a blade server. When I do the HA switchover, my processes lock for about 15 seconds (when using soft mounted NFS directories) before continuing to write to the files their log files on the secondary server. I had thought that since I moved the /var/lib/nfs directory to my drbd shared directory that the failover would be pretty much instantaneous. Do I have a problem in my setup somewhere or is 15 seconds for failover fairly standard? Michael
