Re: [HPDD-discuss] Infiniband & Lustre Module Unloading on RHEL 6.4

Andrew, Rob, We may be seeing some related behavior here as well. Can you give any more details about the errors you're getting on shutdown/unmount? Our problem manifested itself as the MDS not being able to unmount, because it's waiting for communication from the clients, while unmounting/shutting down. (Eventually, messages about hung threads appear on the MDS.) It may not be the sane thing (we're seeing it with 2.5 and have only begun seeing it recently), but it is similar and happening on systems using IB. -- Patrick Farrell Developer, IO File Systems Cray, Inc.
