Can one of the Proxmox Staff members give us an indication of how one can set up a bounty for this or better still, how one can contribute resources so this is being implimented please? This is something we really want, but I can't find info on how we could do this.

I have since added the ceph sources to /etc/apt/sources.list.d/cepg.list as deb http://download.ceph.com/debian-jewel jessie main and added the key manually. The pveceph install -version jewel command would have done that I suppose, but since https://git.ceph.com doesn't have the jewel keys...

A thought I had today was if it would be possible to have a newer version of pve (ie v7) and use an older version of ceph (pre bluestore) which doesn't require as much RAM as the bluestore based version do? Would that be possible?

The problem is not actually Proxmox, it's ceph. As soon as I add OSD's to the cluster, the RAM usage goes up and when I add the 3rd node with a couple of drives, the node crash with out of memory errors. I tried a fresh install with PVE 7, which installed fine, but ceph 16 sank the ship. This...

I have also used the exact setting here, but it gives the same results.

I have to reinstall a couple of nodes on a cluster that I cannot upgrade to a newer version because some of the nodes only have 8 GB of RAM, so I need to get the 4.4 sources. However, something is wrong: ~# cat /etc/apt/sources.list deb http://ftp.debian.org/debian jessie main contrib #...

I have added the VLAN's and made the ports hybrid. For some reason "trunk" disconnected things (probably because we are using VLAN 1). The problem has been solved now.

It's a Mellanox switch on which none of the VLAN are set up because I'm not limiting VLANs to specific physical ports. Do you think that I have to do something special on the switch to get VLAN traffic to be allowed? Simply tagging ip packets with a VALN tag should be enough, not?

However, your answer does not solve my problem in the first instance. Any assistance you can offer there?

Ok, that is what I was thinking when I started out on this effort. But even inside the vms I can't get a network connection or ping the other ip adresses on the VLAN (35 in this case) which doesn't make sense to me.

Another issue that I note it that Proxmox doesn't seem to be aware that there are multiple networks on these nodes. I see that when I try to add a gateway to the bridge for VLAN 35 for example, I get an error saying there's a gateway already. But the gateway it displays is for a different...

As a followup question: Is it enough that I create the VLAN on the enf7f0 nic or should I also tag the bridge interface with vlan 35 when I assign the bridge vmbr4 to a VM NIC?

I have a situation where I need different networks for different application groups on a single pmx cluster. To achieve that I have added VLAN's to the config as below. I have repeated the config on each node of the cluster. I have various virtual machines that are configured on the various...

No. Like I said higher up: "I'd like to use Proxmox Backup Server 2 to store some backups from other clusters here." It's all a test at this stage. We use clusters in different geographical locations and this "test" cluster is in yet another location. But as you can see from my previous...

Thanks, it's sorted now.

I have resolved the problem in a really simply way. Put another way: I was being really stupid. :oops: The lxc is already using ceph as storage, so if I simply increase the size of the lxc disk resource and use a directory as a datastore, I can provision enough storage for all my backups...

I'm struggling to understand from the example here what the complete logic is behind the uid/gid mapping. I have a container (100). I want to map uid 1034 (which I created for this purpose) to uid 1034 inside the lxc. So, following the example in the above documentation, I added to...

I have changed my approach somewhat now by mounting an actual directory of the host OS, which works fine, except that I now have to map the users properly, which I'll do next.

Bump. Anyone?

On this point, let me ask this related question then. I have a proxmox cluster of older machines with about 20 spinning disks on 7 nodes which we use for development work & testing. Nothing to write home about, but stable and due the use of ceph as virtualised storage a dependable and stable...
