Solved Promox and VM replication
-
In my testing I couldn't figure out a way to have hardware raid and ZFS, at least not with one large array.
The only way I could get it to work was to create an R1, leaving unconfigured drives to create the ZFS with so I could then create the ZFS pool.

I need to spin one of these up... are you saying you can't install Proxmox to to a single disk and use ZFS? i.e. one physical drive?
If you can.. .then the hardware RAID should just look like a single presented drive, and use ZFS on it -

See screenshot..... It was not like hard.

Look above.
- I said it is possible I did it.
- I posted a damned screenshot...

I had forgotten that by the time I replied, obviously. I think it's time for me to load up Proxmox in the home lab to check out.

Setup and tested.

When you need it, I think you have to stick to ZFS. Not that there is no possibility of doing it another way, but it's what ProxMox expects at this point.
Sucks, but working.

I'll try and make a cleaner guide later..
- First, spin up your ProxmoxVE system.
- During the install wizard, I left the boot drive as LVM but did change it to XFS instead of ext4. You do not setup secondary drives during the install wizard.
- Once up, you need to create the ZFS store on each system, named the same, prior to joining the cluster.
- The replication process wants the ZFS pool to be named the same on both systems and you cannot name it the same (at least in the GUI) if it already exists anywhere in the cluster.
- The replication process wants the ZFS pool to be named the same on both systems and you cannot name it the same (at least in the GUI) if it already exists anywhere in the cluster.
- Then from the GUI, go to the disks of system 1.
- then click on ZFS and create the storage pool
- name it, single disk, compression off.
- name it, single disk, compression off.
- wait for it to show normal.
- then repeat the process on the second system.
- make sure to use the same name.
- Now create the cluster and join the second system to the cluster.
- You will not see the storage on ZFS storage on system 2 when it first loads up.
- But it does exist if you look.
- To make it available, go to storage under datacenter.
- edit the existing "data" and add pve2
- now it will show up and be available for use.
Is this perfect? No. but it is how I was able to get it setup to work.
The manual leave out quite a bit of specifics. on how to do things, but goes into detail on the technical of things.
- First, spin up your ProxmoxVE system.
