ceph grafana dashboards: rbd overview empty
by Marc Roos 12 Jun '20

12 Jun '20

The grafana dashboard 'rbd overview' is empty. Queries have measurements 'ceph_rbd_write_ops' that do not exist in prometheus (I think). Should I enable something more than just 'ceph mgr module enable prometheus' I am on Nautilus

Upload speed slow for 7MB file cephfs+Samaba
by Amudhan P 12 Jun '20

12 Jun '20

Hi, I have Ceph Octopus 4 Node, each node has 12 disk cluster, which is configured with cephfs (replica 2) + exposed via samba for windows 10G client. When a user copies a folder containing 1000's of 7MB files from windows 10 client getting only a speed of 40MB/s. Client and Ceph nodes all connected in 10G. In the same setup copying 1GB file from windows client to samba getting 90 MB/s. Are there any kernel or network tunning needs to be done? Any suggestions? regards Amudhan P

Adding OSDs
by Will Payne 11 Jun '20

11 Jun '20

Hi, Total newbie question - I'm new to Ceph and am setting up a small test cluster. I've set up five nodes and can see the available drives but I'm unsure on exactly how I can add an OSD and specify the locations for WAL+DB. Maybe my Google-fu is weak but the only guides I can find refer to ceph-deploy which, as far as I can see, is deprecated. Guides which talk about using cephadm / ceph only mention adding a drive but not specifying the WAL+DB locations. I want to add HDDs as OSDs and put the WAL and DB onto separate LVs on an SSD. How?

failing to respond to capability release / MDSs report slow requests / xlock?
by Marc Roos 11 Jun '20

11 Jun '20

I am still having this issue with nfs-ganesha with nautilus. I assume I do not have to change configuration of nfs-ganesha as mentioned here[1]. Since I did not have any issues with Luminous. Does someone with similar symptoms have also this xlock, waiting message?

radosgw-admin sync status output
by DHilsbos＠performair.com 11 Jun '20

11 Jun '20

All; We've been running our Ceph clusters (Nautilus / 14.2.8) for a while now (roughly 9 months), and I've become curious about the output of the "radosgw-admin sync status" command. Here's a the output from our secondary zone: realm <guid> (<realm-name>) zonegroup <guid> (<zonegroup name>) zone <guid> (<zone name>) metadata sync syncing full sync: 0/64 shards incremental sync: 64/64 shards metadata is caught up with master data sync source: <guid> (<master zone name>) syncing full sync: 0/128 shards incremental sync: 128/128 shards 3 shards are recovering recovering shards: [39,41,66] Radosgw is in use, so the active recovery for data doesn't really surprise me. What I am curious about is these 2 lines: full sync: 0/64 shards full sync: 0/128 shards Is this considered normal? If so, why have those lines present in this output? Are they relevant to a different type of replication than what we are doing (I'm not aware of a different type of radosgw replication, but I'm not omniscient)? Thank you, Dominic L.

Octopus: orchestrator not working correctly with nfs
by Simon Sutter 11 Jun '20

11 Jun '20

Hello I know that nfs on octopus is still a bit under development. I'm trying to deploy nfs daemons and have some issues with the orchestartor. For the other daemons, for example monitors, I can issue the command "ceph orch apply mon 3" This will tell the orchestrator to deploy or remove monitor daemons until there are three of them. The command does not work with nfs, and now the orchestrator is a bit missconfigured... And with missconfigured I mean, that I have now a nfs daemon on node 1 and the orchestrator wants to create another one on node 1 but with wrong settings (it fails). Also a "ceph orch apply nfs –unconfigured" does not work, so I can't manually manage the nfs containers. Is there a manual way to tell ceph orch, to not create or remove nfs daemons? then I would be able to set them up manually. Or a manual way of configuring the orchestrator so it does the right thing. Thanks in advance Simon

rbd-mirror sync image continuously or only sync once
by Zhenshi Zhou 11 Jun '20

11 Jun '20

Hi all, I'm gonna deploy a rbd-mirror in order to sync image from clusterA to clusterB. The image will be used while syncing. I'm not sure if the rbd-mirror will sync image continuously or not. If not, I will inform clients not to write data in it. Thanks. Regards
