Thanks for the replies... I changed the name of the MDT to MDT0000 and that seemed to work.
I see this now in my logs: 2014/10/28 12:37:37 [32611/1] CheckFS | '/lustre' matches mount point '/lustre', type=lustre, fs=10.144.60.65@o2ib:10.144.60.66@o2ib:/fsulstr 2014/10/28 12:37:37 [32611/2] SigHdlr | Signals SIGTERM and SIGINT (daemon shutdown) are ready to be used 2014/10/28 12:37:37 [32611/2] SigHdlr | Signal SIGHUP (config reloading) is ready to be used 2014/10/28 12:37:37 [32611/2] SigHdlr | Signal SIGUSR1 (stats dump) is ready to be used 2014/10/28 12:37:37 [32611/1] EntryProc | No class defined in policies, disabling file class matching. 2014/10/28 12:37:37 [32611/1] EntryProc | No class defined in policies, disabling dir class matching. 2014/10/28 12:37:37 [32611/1] ResMonitor | No purge trigger defined in configuration file...

Perhaps it existed or perhaps it wasn't really needed anyway? I'm planning to start a one time scan now. Is there a quick something I can run to verify robinhood is watching the changelog now?

I'm more of a programmer than sysadmin so I'm in over my head here a bit. I've installed robinhood on a server with the native lustre client running. [root@export-60-13 tmpfs]# cat /proc/fs/lustre/version lustre: 2.5.1 Is there a specific reason why you are not using Lustre 2.5.3 ? I think I need to register a new changelog reader with Lustre. Is this correct? # lctl --device fsulstr-MDT0000 changelog_register fsulstr-MDT0000 Registered changelog userid 'cl1' Seems good. Based on that I've got the following for my config file: ChangeLog { MDT { mdt_name = " fsulstr-MDT0000"; There is a blank between in the MDT name. I know I need to do a one time full scan. I presume I should: rbh-config enable_chglogs And then do the full scan after enabling the changelog? Indeed. Right now I get this error when starting the robinhood service which I am assuming is because I need to register the new changelog reader: 2014/10/28 11:03:59 [30797/1] ChangeLog | ERROR -22 opening changelog for MDT 'fsulstr_¦1': Invalid argument 2014/10/28 11:03:59 [30797/1] Main | Error 22 initializing ChangeLog Reader 2014/10/28 11:03:59 [30797/1] ChangeLog | ERROR -22 opening changelog for MDT 'fsulstr_�1': This looks like there is some garbage? strange code data after your filesystem name. Could you check what you put in Robinhood config file is correct? (everything is us-ascii) Aurélien
