[Server-devel] Admin User
Martin, If the admin XO becomes unavailable or needs to be reflashed how does one access the Moodle admin and make a new XO (or the original one reflashed) the admin one?

Re: [Server-devel] Managing global site resources when using segregated groups
On Sun, Dec 20, 2009 at 11:40 PM, David Leeming da...@leeming-consulting.com wrote: That was very helpful, Martin. I will try the global glossary. I also noted that if users are added as guests only, then they can see the resources but are not connected by the presence service. A less elegant way to do it perhaps. Yes, guest access is a possible approach. But truly global resources are in their right place at the site course... and that is supported by ancillary mechanisms within Moodle (ie: glossary autolinking ;-) ) On the B4s below, well I have two C1s and 2 B4s and they were all updated with exactly the same flashdrive (build 802 and same activity bundle). So they should behave identically apart from hardware issues. But the issue below remains, any other clues I can look for? Ok, that's very weird. Tell me, are they registered ok? Check that... - the XO does not list 'register' in the menu - the XS lists the XO when you run /home/idmgr/list_registrations - in Moodle, the 'course admin' user can see the relevant user account under admin - users - browse To be frank, I initially doubt it's a hw/sw problem because the authentication depends on Browse.xo reading serial number / uuid of the machine. If the sn/uuid are not readable (due to bad hardware, or bad OFW), then the registration would fail as well. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

On Mon, Dec 21, 2009 at 3:14 PM, Martin Langhoff martin.langh...@gmail.com wrote: Now it's up on a pristine state, and I am monitoring it... Ok - the problem seems related to Moodle's control of ejabberd presence service. The sync between Moodle and ejabberd data (in mnesia) was taking too long, and a second Moodle sync process would start... and then a 3rd... and then... This led to errors that should be benign (an error reported in the logs, but not leading to a functional problem) -- because ejabberd's internals are all about supporting things that happen concurrently. But! something inside ejabberd isn't liking the concurrency. I've added a big lock around the process, so from now on Moodle processes won't overlap in this sync. This means that your server is now running a lightly patched Moodle -- I will release this as a new rpm soon. According to ps_mem.py, beam started at 14MB and now grown to 16MB, this is with no users connected. In normal operation (once users connect), I would expect it to grow to ~40MB. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
