Ceph

I keep running into this, my monitors keep running out of inodes which causes them to stall.

Right now I have cron's like:

@daily find /var/lib/ceph/mon.logger/logm -type f -ctime +7 -delete

pgmap already gets trimmed, but the logm doesn't.

I was thinking about a cron which runs every day and ships with the Ceph packages, would that be OK? Or do you prefer to implement this in the monitor itself?

We should probably just do this in the monitor. The logm is never read so it's safe to delete whenever, unlike the other maps we're concerned about.

log trimming fixed by 4c1cb28cb6cbb3d23a1736d02f6af524481c886a

osdmap, mdsmap, monmap still need trimming, but that's a whole 'nother thing.
