Re: Full OSD with almost empty pools

Hi Adam,

I recall a case where pretty high OSD utilization was caused by no trimming for osdmaps.

You might want to check the output of 'ceph tell osd.N status' command and compare oldest_map vs. newest_map values.

Having a delta in hundreds of thousands of epochs would confirm the case.


Thanks,

Igor
