<DIV><SPAN class=908111115-04072005><FONT face=Arial size=2>I would like to be
sure which method to test GFS-6.0.2.20-1installed 3 node file cluster doesn't
corrupt data while multiple nodes writing on the same file. At the same time how
LOCK_GULM manage filesystem ? Is there any known test? or benchmark other than
bonnie++ . I would like to deploy 3 filesystem, each one on one gfs server and
export these file systems with smb to other smb clients. I plan to use 3 smb
instance for all 3 filesystem on every server node and load balancer in front of
them.</FONT></SPAN></DIV>
