Hi David,
I guess you are using FUSE mounts?
Does you app is capable of using libgfapi ?
Best Regards,

Hello,
We switched a production system to using GFS instead of NFS at the weekend, however it didn't go well on Monday when full load hit. The application started crashing regularly and we had to revert to NFS. It seems that the problem was high network traffic used by GFS.
We've two GFS nodes plus one arbiter node, each about 1.3ms latency from each other. Attached is a chart of network traffic on one of the GFS nodes. We see that it saturated the 1Gbps link before we reverted to NFS at 15:10.
The question is, why does GFS use so much network traffic and is there anything we can do about it? NFS traffic doesn't exceed 4MBps, so 120MBps for GFS seems awfully high.
It would also be good to have faster read performance from GFS, but that's another issue.
Thanks in advance for any assistance.
