Strangely Normal (Sep 10 2007)

So it was a busy weekend, with our focus mostly on thumper (the science database server). There were actually two separate problems. Three drives within four days failed somewhat spuriously. We are fairly convinced at this point that they didn't actually fail - I actually took them out of RAID control this morning and am heavily exercising them without any errors. Why they seemed to fail is still a mystery. We are running an older version of Fedora Core on this system and therefore an older version of mdadm. Or is it drive controller issues? Or just error-level threshholds that need tweaking to be less hypersensitive to transient I/O issues? Meanwhile, perhaps due to all the above, an index in the database got corrupted and needed to be dropped/rebuilt which took all of Thursday night to Friday afternoon to complete. Add all this up and we weren't able to create/assimilate new work for most of the weekend. I did get the assimilators going on Friday night, and when the smoke cleared Jeff got the splitters running on Saturday. So far so good.

We were expecting more spurious disk failures, but so far nothing. In fact today has been strangely normal. Tomorrow we may try implementing a method of distributing workunits around our local network so we aren't so choked on that one NAS server which can only do so much. We need to get more headroom before we can try to win participants back. As it stands now given our current level of redundancy we can barely keep up with demand.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind

They don't have much luck really!:Q

And Taiwan are about to pass us after we passed them in SETI classic about 6-7yrs ago!

Thanks for the stats, Rattledagger!

Just got back from a trip to Austria - all is well; I am crunching - as announced - some 500 - 550 credits/day.
