[Linux-cluster] Slow data writing rate



Hi,
I am administrating one site having IBM X255 server with IBM FASt T500 storage with fiber optic link using Qlogic 2300 controler.The site was set up few years back with RHEL AS 2.1.Now it is observed that when cluster service is up writing data in a cluster partition is very slow (in KBs) as it was expected to be at least in terms of 100MBs.The Qlogic speed is 2 GBPS.It also found that whenever cluster service is st oped and cluster partition mounted manually with general mount command data writing speed is nearly 1GBPS.Please suggest the solution of this problem.
Regards,
Prolay Chatterjee
