Message 938179 - Posted: 7 Oct 2009, 20:35:19 UTC

The replica recovery is on hold for a while. We've experiencing random, intermittent issues when trying to recover one database with a mysqldump from another. This used to always work perfectly, but then something in mysql 5.1 screwed up the quoting and backslashing. I was able to get around this before by writing a script that parsed the large dump files one line at a time, but even that isn't working now. Bob has found other complaints on the web about this, so maybe there's a bug fix somewhere (we're certainly not going to pore through 20GB of ascii looking for missing backslashes and whatnot). We might have to do another dump from scratch, which won't happen until next week, which means the replica may be offline until then. Still, when we recover from the outage (and the weekend backlog) I might still turn on the "show results" flag so users can see recent result history, etc.

I'm working on a second test file to help solidify our warm feelings towards the software radar blanking suite. This will get split/sent out tomorrow (unless I suddenly disappear on an impromptu vacation, which is known to happen from time to time).

Due to popular demand I put a little effort in this morning to cleaning up the technical news main page - it's been a while since I have done so, so the page has gotten rather large and painful to load for people on slow connections.

Can just the daily BoincStat dump be re-pointed at Mork for this week? Or would that mess up the stats worse than waiting?

I know for everything else it's a resounding No ;-)

As far as I know everything is pointing at mork right now. Let me know if it seems like I'm wrong about that.

Dump has appeared on schedule, and gross total credit has gone up from 57,096,271,778 to 57,184,239,144 - looks A-OK from here.

If the "Cricket graph" is considered to be a good indicator of current workload,
it looks like we're out of the woods... or maybe not?

I use 'mysqldump -O net_buffer_length=32760 --opt -Q' for dumps, but I just noticed I'm still on 5.0, so that will probably be why I haven't come across the backslash/quoting issue.

It would be nice to have the task list/s available.
Maybe also the pending credits..

Everytime I change/do something on my PCs this isn't available.. ;-)

Some times you need to run away from it all. You think better when you get back.

Couldn't detect such a signal as far out as you think.
