Ceph DB

Hi, If I set in a running cluster the rgw_bucket_default_quota_max_objects with the ceph config set (mgr/mon not sure which to make it global) rgw_bucket_default_quota_max_objects 1000000 will it overwrite the existing special buckets where I've already set higher values? Or keep in untouched? Ty ________________________________ This message is confidential and is for the sole use of the intended recipient(s).

bluestore_min_alloc_size sizing
by Arkadiy Kulev 30 Jun '21

30 Jun '21

I know that this might be a dumb question, but asking just for future googlers' sake. If *bluestore_min_alloc_size* is set to *64KB*, will a *70KB* object be stored as *128KB* or *70KB*? Sincerely, Ark.

Re: Pacific: RadosGW crashing on multipart uploads.
by Chris Palmer 30 Jun '21

Hi Vincent It may be Bug 50556 <https://tracker.ceph.com/issues/50556>. I am having this problem, although I don't think that characters in the bucket name is relevant. Backport 51001 <https://tracker.ceph.com/issues/51001>has just been updated so looks as though it will be in 16.2.5. At a glance your symptoms sound similar but I'm not sure if the crash info is the same.

upgrading from Nautilus on CentOS7 to Octopus on Ubuntu 20.04.2
by Jean-Philippe Méthot 29 Jun '21

29 Jun '21

Hi, I’ve been running a staging Ceph environment on CentOS 7/Nautilus for quite a while now. Because of many good reasons that you can probably guess, I am currently trying to move this staging environment to Octopus on Ubuntu 20.04.2. Since I’m trying to keep the data, but don’t mind downtime at all, my plan was to reinstall one server at a time, removing them from the cluster and adding them back to the cluster, since Octopus and Nautilus should still be compatible with each other. I started with one monitor and now I’m stuck in a weird state. Essentially : -Monitors see each other and are establishing connections to each other. -Monitor clocks are synchronized -Monmap was injected in the reinstalled monitor -New monitor is recognized in Ceph -s but stuck out of the quorum Is there something that could prevent a new monitor from establishing quorum if the monmap is the same, the clock is synchronized and it can contact other monitors on the network?

Hi- I recently upgraded to pacific, and I am now getting an error connecting on my windows 10 machine: The error is the handle_auth_bad_method, I tried a few combinations of cephx,none on the monitors, but I keep getting the same error.

[cephadm] Unable to create multiple unmanaged OSDs per device
by Aggelos Avgerinos 29 Jun '21

29 Jun '21

Hi everyone, I'm currently trying to setup the OSDs in a fresh cluster using cephadm. The underlying devices are NVMe and I'm trying to provision 2 OSDs per device with the following spec: ``` service_type: osd service_id: all-nvmes unmanaged: true placement: label: osd data_devices: all: true osds_per_device: 2 ``` Since `ceph orch apply` just creates the service but not the daemons when `unmanaged: True`. Is there a way to enfore the `osds_per_device` setting when using `ceph orch daemon add osd`? Thanks in advance
