[OpenAFS] salvage removed .6M files!
Fri, 29 Jul 2005 16:44:10 -0500
More information, fwiw...
- SalvageLog.old indicates (the initial) salvaging started
- BosLog indicates that that salvage exited with signal 15 at
- SalvageLog indicates another salvage--the one that went
awry--started at 05:00:38 and completed 06:44:41
- bos getrestart reports the server should restart for
new binaries at "5:00 am"
It is possible the "restart for new binaries" erroneously happened,
and it kill -SIGTERM'ed the bos salvage which left the volume
in an inconsistent state that caused the subsequent salvage to
blow chunks?? (I'm under the general impression that interrupting
salvages is a bad idea.)
At any rate, I've turned off the "restarts for new binaries at
5:00 am" thing.
