Hi
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.
Platform
: 3x HP-DL380 G4
OP
: RedHat Enterprise Linux Advanced Server 3.0 Update 4
Cluster
Suite : 3.0, clumanager-1.2.22-2
redhat-config-cluster-1.0.3-1.noarch.rpm
GFS
:
GFS-devel-6.0.2.20-1
GFS-modules-smp-6.0.2.20-1
GFS-6.0.2.20-1
GFS-modules-smp-6.0.2.20-1
GFS-6.0.2.20-1
