[Pvfs2-users] pvfs2 over InfiniBand unstable problems

[xiangyong ouyang]

I have set up pvfs2 over IB to run some experiment.

I use a machine k8 as MDS, k10 and k11 as IO server. one machine k7 as client. servers can detect pvfs2 successfully using pvfs2-ping. client k7 can mount pvfs2 fs successfully, and can read/write pvfs2 partition.

when I run "iozone"( a file system benchmark) on k7 to test pvfs2 fs performance, it reports error:

Error writing block 95, fd= 3
write: Operation not permitted

Error writing block 97, fd= 3
write: Operation not permitted

Error writing block 94, fd= 3
write: Operation not permitted


could you help me to detect the problem? thanks!
