Hello,
We had some issues with context switches using the GlusterFS FUSE client -
& we are processing a large number of small files.
We decided to switch to NFS to see if that would increase performance, but
are having issues with the NLM locking functionality.
Using http://wiki.samba.org/index.php/Ping_pong - we are able to verify
that a single F_SETLKW call is blocking indefinitely.
ping_pong -r glusterfs_test.txt 1
Hangs on this line blocking for a wait lock:
return fcntl(fd,F_SETLKW,&lock);
The root cause appears to be this in the glusterfs/nfs.log:
*RPC Program procedure not available for procedure 5 in NLM4*
*
*
Is there any more information on this error, or how it can be resolved?
