[Linux-cluster] GFS2 Problem



Hello,
 
We have a 24 node cluster with shared gfs2 partitions used for shared software (computational software, compilers, etc.) and users home directories.  Periodically we’re seeing the below messages in dmesg and eventually users are unable to login due to what I assume is problems getting locks on the necessary files.  When the problems starts commands like gfs2_tool df or ls (on the gfs2 directories only) hang.  After a reboot it’s fine for a while, but after a day or two we’ll start seeing the same messages again.  I’ve been looking through the documentation and it looks like everything is setup correctly, but it’s possible I missed something.  Does anyone have any suggestions on what might be wrong?  I’d rather get this working correctly than scrap it and use NFS as the shared storage.
 
The kernel across all nodes is version 2.6.18-194.11.3.el5.  If there’s any other information that would be useful let me know and I will gladly provide it.
 
Dmesg output:
