Well my saga with /home locking up was partially resolved for about 6 hours today. I rebooted the MDS and re mounted the MGS and lustre MDT and home MDT and after a while it all came good, then rebooted each compute node and we were operational for about 6 hours when it all locked up again, /lustre worked fine but /home just locked solid.. I'm suspecting corruption but I don't know how to fix it...
I have found that once I restart the MDS I can do a remount of home and all the D state processes come good and we are up and running. Is there a tool that can specifically check an individual MDT / OST etc? Sid Young
