I would like to know if you know how I can shutdown ALL VM / CT in parallel ? (as in the GUI). I have setup a script to shutdown VM, CT and then set the noout flag on the CEPH Cluster and finally shutdown the server. Problem is that the script iterates with a for loop (which causes VM to be...

File level backup is not performant in PBS. PBS is good for backing up VMs. If your file are hosted on a ZFS system, you'd better use some scripts + ZFS snapshots which are native to your OS. Both your native system + target needs to be on ZFS though.

This is working and seems to solve the pb.

I have noticed these errors on my cluster (on every node for all my osd) : Dec 20 22:00:28 pve1 ceph-osd[3991]: 2021-12-20T22:00:28.350+0100 7fbd20fa4f00 -1 osd.2 1257 mon_cmd_maybe_osd_create fail: 'osd.2 has already bound to class 'nvme', can not reset class to 'ssd'; use 'ceph osd crush...

Thanks for your answer… I have managed using an SSH + port forward to access the GUI, which is way simpler to solve my problem: ssh -L 8006:127.0.0.1:Destination_IP_Of_Old_PVE:8006 root@mypbs_system Then just https://127.0.0.1:8006 and you are done ;-)

Hello, I am migrating a big server to a new architecture, transitioning from ZFS based cluster to Ceph cluster. We are using pbs as an intermediary backup / restore stack. server where data / VM to be migrated is located is headless. All VMs have been migrated but one, which remains on the...

Thanks for your reply. We were more or less planning what you described on the the target scenario that we have. Backup with our PBS of all VM + CT Restore on the new Ceph Cluster The only risky point is if the migration fails for one reason or another… Then we will have to roll-back to...

CEPH public and private networks are totally separated from the other part of the storage. My question was more related to the PVE cluster itself (corosync). Would It cause any problem to have a mixed Corosync cluster with both CEPH based nodes (running on AMD proc) and ZFS based ones...

Hello, We will migrate a working cluster based on four nodes (ZFS) into a larger cluster with three nodes based on CEPH. We wanted to know if it would be "ok" to join all nodes on a mixed Proxmox cluster with : standalone nodes based on ZFS (Intel) working cluster nodes based on CEPH (AMD)...

# pveceph purge This did the trick !

I have noticed that the CEPH public / private network weren't properly created during the execution of the Ceph installation wizard. Unfortunately reloading the page killed the process and I can't seem to find a way to relaunch the Ceph installation wizard ? Any idea how I could do that, I'd...

We have been working for long time on the deployment of a cluster based PVE and the new SDN feature. We have had the chance to work with BGP expert and also some of the people involved in the dev. of the project. So this report is a bug report after we moved the cluster to v.7 of Proxmox. We...

Ok - thanks.

I just wanted to make sure that we could have an AMD based PBS in order to bckup an Intel PBS infra ? Thanks

Hello, I am looking for a way to automate the restoration of a snapshoted VM to it's snapshoted initial state. This is a testing environment that we provide to our prospect and I would like to kick back every night at a giveng time to the snapshotted version. Do you know how I can : list...

A little feedback on this one. If you want to simply use : 192.168.15.4,192.168.15.3,192.168.15.2,192.168.15.1:/ /mnt/mycephfs ceph name=gregober,secret=your_secret,rw,noatime,_netdev 0 0 You will only need the package ceph-fuse to be installed. But if you want or need...

I have a PBS system where I need to mount a CephFS FS. I have managed to mount this using this command: mount -t ceph 192.168.215.4,192.168.215.3,192.168.215.2,192.168.215.1:/ /mnt/mycephfs -o name=bob,secret=xxxxxxxxxxxxxxxxxxxxxxx== This is working like a charm and I have access to my...

I have done what you have suggested and I have found the data ! You were right. In this thread I have described my problem with ZFS not mounting my second pool (backup). So the initial datastore that I have created have been setup on the rpool and not on backup. Thanks to your command the...
