Re: High usage (DATA column) on dedicated for OMAP only OSDs

Hi Alexander,

I recall a couple of cases when permanent osdmap epoch growth has been filling OSD with relevant osd map info. Which could be tricky to catch.

Please run 'ceph tell osd.N status" for a couple of affected OSDs twice within e.g. 10 min interval.

Then check the delta between oldest_map and newest_map fields - neither the delta should be very large (hundreds of thousands) nor it should grow rapidly within the observed interval.

If so - please share these reports, 'ceph health detailed' output and exact Ceph release version you're using.


Thanks,

Igor
