What's the connectivity? SAN or NAS? Is it on physical RAID? Are you accessing the same file?
I have notice inconsistent access across iSCSI, as a result of network bandwidth, buffering, caching, et al.

Date: Friday, June 12, 2009, 8:40 AM
We are running gfs2 on Red Hat Enterprise Linux Server release 5.3 (Tikanga)
This is a 2 node cluster and what we have noticed is that from time to time, one node gets approximately 1/3rd write thruput on gfs2 as compared to the other node.
Writing program is in java.
Any ideas on what to check for etc.?
Many thanx,
Tajdar
