Hello, I'm following this guide to upgrade our cephs: https://ainoniwa.net/pelican/2021-08-11a.html (Proxmox VE 6.4 Ceph upgrade Nautilus to Octopus) It's a requirement to upgrade our ProxMox environnement. Now I've reached the point at that guide where i have to "Upgrade all CephFS MDS daemons" But before I started this piece, I checked the status. root@pmnode1:~# ceph status cluster: id: xxxxxxxxxxxxxxx health: HEALTH_ERR noout flag(s) set 1 scrub errors Possible data damage: 1 pg inconsistent 2 pools have too many placement groups services: mon: 3 daemons, quorum pmnode1,pmnode2,pmnode3 (age 19h) mgr: pmnode2(active, since 19h), standbys: pmnode1 osd: 15 osds: 12 up (since 12h), 12 in (since 19h) flags noout data: pools: 3 pools, 513 pgs objects: 398.46k objects, 1.5 TiB usage: 4.5 TiB used, 83 TiB / 87 TiB avail pgs: 512 active+clean 1 active+clean+inconsistent root@pmnode1:~# ceph mds metadata [] as you can see there is no mds service running. What can be wrong and how to solve this? Thank you in advance.
Hi, I’d suggest to check the servers where the MDS‘s are supposed to be running on for a reason why the services stopped. Check daemon logs and the service status for hints pointing to a possible root cause. Try restarting the services and paste startup logs from a failure here if you need more advice.

I also would recommend bringing all pgs into a active+clean state before you upgrade the cluster. www.clyso.com Hohenzollernstr. 27, 80801 Munich Utting a. A. | HR: Augsburg | HRB: 25866 | USt. ID-Nr.: DE2754306 Am Sa., 14. Sept. 2024 um 14:18 Uhr schrieb Ex Calibur <permport@gmail.com>:
