Out setup is:
* We are using GFS from cvs stable branch on our 2.6.14.7
cluster. Just updated today to the
newest CVS version. Only had to change the mutex() calls.
* The 4 nodes are running debian sarge;
* The 4 nodes act as NFS-servers for +/- 640 client-nodes
* brocade switch with SGI TP9300 4 controllers (15 TB)
We did a lot of testing an we could not crash the cluster, bonnie/
iozone and other tools/jobs. Now the cluster is in production we
get a lot of nfsd crashed with EIP is at fda_create. We had it with
our previous kernel 2.16.4.4 and with this one and "latest"
CVS stable version. The server still runs ++ the load is high and
it does not respond any more. If we are luckly only one NFS
thread is gone and rest is still up. The rest of the nodes still work.
Have users experienced this kind of problems and maybe have a
solution for this problem?
