[ceph-users] Re: Reset dashboard (500 errors because of wrong config)

Hi, you could try to set config keys, but I'm not sure if this will work. What do you get if you run this: ceph config-key get mgr/dashboard/_iscsi_config obtained 'mgr/dashboard/_iscsi_config' {"gateways": {"ses7-host1.fqdn": {"service_url": "http://:@:5000"}, "ses7-host2.fqdn": {"service_

[ceph-users] Permission problem upgrading Raspi-cluster from 16.2.7 to 17.2.0

Hi, Yesterday I upgraded my smallest test system, 4 Raspberries 4B, from Pacific 16.2.7 (cephadm/containerized) to 17.2.0 using ceph orch upgrade start --ceph-version 17.2.0 It mostly worked ok, but wouldn't have finished without manual intervention. Apparently each time a mgr is upgraded the pr

[ceph-users] Upgrading Ceph from 17.0 to 17.2 with cephadm orch

Hi, I've upgraded my cluster using 'ceph orch upgrade start --image quay.io/ceph/ceph:v17' in cephadm shell. All went great. 'Ceph tell osd.N version' reports the updated version 17.2.0 (Quincy, Stable). Only it seems that the ceph docker image on the initiated host is updated, the other aren

Hi, There’s previous discussion about this issue. https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/ZZZGEVD4L4SEMEBMTZYDW2OOVWQFXGOA/ Can you check if there is any host with _admin label on it? Removing the label works for me. Regards, Gene Kuo > On Apr 27, 2022, at 18:21, Ulri

[ceph-users] Re: Permission problem upgrading Raspi-cluster from 16.2.7 to 17.2.0

Yup, looks exactly like the problem described in that thread. For the next cluster I’ll try without the _admin labels. I think I added them because without the label the files in /etc/ceph ever so often “magically” disappeared. So I’ll save copies of them before doing the upgrade. Thanks, Uli

Hi Vladimir, just try manual DB compaction through ceph-kvstore-tool for these OSD. Highly likely it's a known issue with DB performance drop after bulk data removal. Thanks, Igor On 4/25/2022 8:47 PM, Vladimir Brik wrote: Hello I have 3 OSDs that are stuck in a perpetual loop of heartb

[ceph-users] Re: Recommendations on books

Hi, I don't have any book suggestions, but in my experience, the best way to learn is to set up a cluster and start intentionally breaking things, and see how you can fix them. Perform upgrades, add load, etc. I do suggest starting with Pacific (the upcoming 16.2.8 release would likely be a good
