[ceph-users] feature_map differs across mon_status

Just curious why the feature_map portions differ in the return of mon_status across a cluster. Below is an example from each of five mons in a healthy 16.2.10 cephadm cluster: root@mon.d:~# ceph tell mon.a mon_status | jq .feature_map { "mon": [ { "features": "0x3f01cfb9fffd",

[ceph-users] Re: DB/WALL and RGW index on the same NVME

Hi, Yes, that documentation you are linking is from Ceph 3.x with Filestore, With Bluestore this is no longer the case, the link to the latest Red Hat doc version is here: https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/7/html-single/object_gateway_guide/index#index-pool_rgw

[ceph-users] Re: DB/WALL and RGW index on the same NVME

I would suggest that you might consider EC vs. replication for index data, and the latency implications. There's more than just the nvme vs. rotational discussion to entertain, especially if using the more widely spread EC modes like 8+3. It would be worth testing for your particular workload.

[ceph-users] Re: DB/WALL and RGW index on the same NVME

Hi Lukasz, RGW uses Omap objects for the index pool; Omaps are stored in Rocksdb database of each osd, not on the actual index pool, so by putting DB/WALL on an NVMe as you mentioned, you are already configuring the index pool on a non-rotational drive, you don't need to do anything else. You
