i'm looking for some help/ideas/advices in order to solve the problem that occurs on my metadata
server after the server reboot.
"Ceph status" warns about my MDS being "read only" but the fileystem and the data seem healthy.
It is still possible to access the content of my cephfs volumes...
I have a cluster with 3 nodes (pve, pve1, pve2)
Here the version information:
root@pve:~# pveversion -v
proxmox-ve: 6.4-1 (running kernel: 5.4.157-1-pve)
pve-manager: 6.4-13 (running version: 6.4-13/9f411e79)
Hello, we've noticed some latency in the last month in our ceph cluster and when I checked ceph dashboard I found this warning in the attached file. As I understood this means mds_cache_memory_limit property is not configured correctly. Can that be the reason why we experience latency in the...
I wanted to use the Cephfs (I'm still testing proxmox for migrating from XCP-ng).
I then wanted to remove everything, but I ended up with a standby MDS (only) and I cannot remove it.
It seems to be that the Host is 'Unknown' and when I delete/stop it, I have : "entry has no host"
i posted in another thread (https://forum.proxmox.com/threads/proxmox-6-ceph-mds-stuck-on-creating.57524/#post-268549) that was created on the same topic and just hopped on to it, but that thread seems to be dead. so i am trying my luck here to see if this is a general problem...
I am a little bit confused or maybe I am just missing a small detail.
My plan is to deploy and mount a cephfs directory on a samba VM.
Thus I created a MDS in the proxmox cephfs GUI but the address of the MDS is from my cluster network where the OSDs are communicating.
Well, I tried to...
I just upgraded to version 5.3 and tried to create multiple MDS for CephFS. However, an error occurs:
Binary not installed: /usr/bin/ceph-mds (500)
Is this intended? I cannot install it via apt. What is the issue here?
Am posting this here in case anybody searches for this in the future.
# Install Ceph MDS on Proxmox 5.2

We are using ceph-fuse to mount a CephFS volume for Proxmox backups at `/srv/proxmox/backup/`.
Recently, I noticed that the backup volume kept running out of free space and therefore the backup jobs were failing (we had a Ceph quota of 2 TB in place on the pool for safety reasons)...
Been trying to deploy MDS & CephFS by compiling a couple of very scarce threads from here & there.
But no luck till now. Ceph-deploy tool does not work as expected and couldn't
start the MDS after manually adding the [mds] section etc in ceph.conf
Is MDS and CephFS management in...
