[Ocfs2-users] RHEL4 x86_64 OCFS2 10gR2 performance

[Marcio Costa]

Hi,

I have 2 IBM x346 eServers, both of them with 2 Qlogic HBAs (qla2340). They 
are connected rendundantly to a IBM DS4300 (fiber storage). I have Oracle 
10gR2 RAC installed. RHEL4 U2 x86_64. My problem is the following:

Each server works very well, if alone,ie, if the other one has not mounted 
the ocfs2 partition. But when both of them are working, the performance goes 
to hell. 
For example: there is a job that, when it runs on one server alone, takes 4 
seconds, but when I put both servers on line, it takes 3 minutes.

What could it be ? Is there any conf that I could check. I was thinking 
about change the ocfs2 for other fs (gfs or other)... could it be the case ?

Thanks in advance.

Marcio Costa.
