[ceph-users] Re: Frequest LARGE_OMAP_OBJECTS in cephfs metadata pool

[ceph-users] Changing allocation size

Hi all, A while back, I indicated we had an issue with our cluster filling up too fast. After checking everything, we've concluded this was because we had a lot of small files and the allocation size on the bluestore was too high (64kb). We are now recreating the OSD's (2 disk at the same time) bu

[ceph-users] Migrating data to a more efficient EC pool

Hello I have ~300TB of data in default.rgw.buckets.data k2m2 pool and I would like to move it to a new k5m2 pool. I found instructions using cache tiering[1], but they come with a vague scary warning, and it looks like EC-EC may not even be possible [2] (is it still the case?). Can anybody
