All, I've seen a few posts about this issue in the past, but not a resolution. I have a 3 node cluster sharing ocfs2 volumes to app nodes via nfs. On occasion, one of our db nodes will have nfs go into an uninterruptable sleep state. The nfs daemon is completely useless at this point. The db node has to be rebooted to resolve. It seems that nfs is waiting on ocfs2_wait_for_mask. Any suggestions on a resolution would be appreciated.
