So the focus is still on thumper, the science database/raw data server. Last night we finished resyncing all the root drives (a three drive mirror). We still have to do some swapping to install grub on the third and final drive - we'll do this during the outage next week. Until then we're officially resuming normal operations, at least at the server level. Phew. I started up several raw data transfer jobs since that's been backed up for a week.

Now we can turn our attention to the database. We're dumping the entire pulse table to a file so we can recreate the table in a larger set of db spaces. This is basically all you can do when you run out of extents - unload the table, then reload into new db spaces. I roughly estimate the unload will take at least 24 more hours.

Since we couldn't insert pulses until we got more extents, the assimilator queue grew fairly large. So why stop now? There's really no reason not to split/create new multibeam workunits - we can still insert workunits into the science database. So I started a single multibeam splitter if only to satisfy some workunit demand until we can assimilate again. Of course, if we can't assimilate, we can't delete - and we've been running low on space to store workunits. But being that we've been running only astropulse for a day that actually helped push a lot of ap workunits/results through the validation/assimilation/deletion queues, which in turn cleared up a fair amount of storage. So we're good for the moment, at least storage-wise (seems like even the one splitter is sensitive to the current heavy load on thumper).

Tomorrow is actually an official university holiday (the staff gets its one day of spring break). However, like always, Jeff, Eric, Bob and I will be poking and prodding at the servers remotely over the weekend.

Enjoy your long weekend. Hope we can stay out of trouble long enough for you to get some time for yourself. :) We really do appreciate all you do to keep us crunching.

Hey guy's,

If you are still out there tweaking and converting please take a beer and know we appreciate it!

Are we assimilating now? If so, would it be ok to start another MP splitter?

have a good weekend.

Are we assimilating now?

Nope.
From memory it won't be possible till they sort out the pulse table problem, and the estimate for that is about 24 hours from when they start.
