<div>What makes you think running salvage is a good thing? I had
gotten to the point where I would avoid running it like the plague --
using tools such as fast-restart -- and in the time I was running
fast-restart, which included some rather nasty power events which took
things down hard. And, believe it or not, even in those incidents I
only had one or two volumes that I had to hand-salvage.</div>

I usually run salvage by hand once or twice a year, but my gut says run
it more often. I'll write a script that runs on odd months and call it
from either linux-cron or afs-cron. One drawback of afs-cron is it
only knows a weekly time schedule. Could we put that on a wish list?<br>

Is this too often? Any reason not to? What are others doing? Thanks.

<pre wrap=""><!---->At my last *cough* site, we ran with fast-restart. Because of the
cruft that would sometimes get left behind in volumes due to things
like crappy fortran compilers, I would run a salvage on each server
every 2-3 months. As there were rarely any real errors, it ran
pretty quickly and would fit in my "official downtime" window.
I used to run 'em by hand because, well, I only had like 6 servers
(and I'm a hands-on kinda Moose), but it easily could have been
automated.
