Maybe I wrongly assume that you need to have the same hostname for both MGMT and DRBD addresses?

Sorry but this makes very little sense to me. Luckily it's not a big deal I guess.

Sorry the dumb question, but how is the system supposed to know when it should resolve the hostname as IP of management or IP of the DRBD network?

Yes. Exactly same behavior. I was about to open a thread but you beat me at it.

YES!!!! So let's recap, do we just need to insert that line uncommented and that's it? No reboot? I've done it and it seems to work amazing, however the strange part is that I didnt need to do the last part (the pvmove). The VM booted just fine anyways. Here's some output, just in case someone...

Hello, I am a little confused when it comes to implement a separate network for DRBD9, because I'm supposed to have a resolution in my hosts file for both corosync (PVE cluster) and also for DRBD. So I'm not sure how am I supposed to setup my hosts file. Anyone with an HA cluster + DRBD9 can...

Hi Mark, could you please provide us with additional info about why having only two OSD nodes would not give you full HA? If I understand correctly...

Ok I reply to myself: apparently the PVE implementation of Ceph only allows you to use whole drives, and not just partitions. That's going to be an issue because I'm not sure if I can afford two more SSD's, it's just an home setup. I need to check the fesibility of using USB sticks to boot PVE.

Actually just the fact that I wish to run a three nodes cluster but the third node should be just for quorum but Ceph will require to set up data storage for this node too. Not a huge deal I guess. Another problem is that I cannot assign a full disk to Ceph, only partitions. This is because I'm...

Please help. The support for thin provisioning in DRBD9 seems to be not stable enough, as declared by them. As a matter of fact, I lost a test VM few hours after creation, and they say that this is possible. However, thick provisioning with DRBD9 is considered to be stable. So, I really cannot...

Thank you for the prompt reply. I come from an environment where I used LVM's on a single PVE node, so DRBD, ort any replication system, was not required. At that time, I used Thick LVM's over Thin LVM's because I don't need to allocate more space than it's required; infact, I would prefer to...

Hello, I'm following the tutorial at https://pve.proxmox.com/wiki/DRBD9, but it seems that I'm only allowed to use thin LVM's, and not thick provisioning. In fact, the command you're suggested to type is: root@proxmox:~# lvcreate -L 511G -n drbdthinpool -T drbdpool Is it actually possible to...

I understand. Onthe other hand, DRBD9 would allow me to have redundant storage in two nodes only, but it also seems to require a separate drive, meaning you cannot have Proxmox and storage on the same phisical media, which would note be great for me. Is it the same for Ceph too?

Sorry, just a clarification. At minimum, Ceph requires three nodes, is that correct? So this means I can't have the third "light weight" server just for quorum, but it also must replicate the Ceph cluster, or at least a part of it. Am I right?

Maybe I should've mentioned that I plan on using VE 4.2, and I belive that support for DRBD8 is discontinued. Ceph does look interesting indeed, the problem is that it's a really new concept for me and I'm struggling to find where I should start to learn it. I've purchased the latest book...

Hello, I'm willing to setup a Proxmox HA cluster based off three nodes, where one of them is virtualized onto a different host, since it's just for quorum purposes. I would like to have local redundant storage on both of the two mail nodes (and maybe even the third if needed for ceph), so I'm...

I now happen to nave two spare xeon with 16G ECC RAM, so I figured that I could use both of them, at least for some time just to grasp a good knowledge of proxmox. Or maybe indefinitely, its just 40 watts each... The point is that I don't seem to find enough comprehensive documentation about...

Because I already have a nice hardware to comfortably run Proxmox on it, and actually USE it as hypevisor. So in your opinion, having a 3 nodes solution with one "low resources" node, as the guys before me also suggested, is rubbish?

Please don't get me wrong, I'm just trying to figure out how clustering (with proxmox at least) work. I understand that I need at least three nodes to have a reliable cluster, but of course I'm interested into a non expensive setup for home-lab purposes. I know that having a node just for quorum...

Sorry about that. So, let's say I give up on having HA and I stick on manual migration with a cluster of two nodes.... can I still have DRDB to sync the local storage? Does it make sense?
