The mysql replica was turned back on today, then turned back off - Bob noticed it was still misconfigured, so he's re-recreating it and will probably turn it back on soon (within the next 24 hours).

Meanwhile, the software blanking pipeline is still warming up - actually some workunits from 2006 will go out (secretly) very soon. It's hard to tell how fast I can get this data up from HPSS and blanked. It all may be too slow to keep up with workunit demand, but we'll do what we can. It's hard to automate this stuff - I find the more I automate things the more time I spend cleaning up large, unexpected disasters.

Thanks for the update on the automated disasters.

Too err is human, to really screw it up required a computer. :)

If it is too slow on S@H servers, would it be a decent candidate for distributed work over BOINC? (of course, if you have to blank a whole tape at once, the answer would be no).

Have you considered asking the Lunatics crew to optimize the blanker?
