Proxmox Attach ZFS Pool?

[proxmon]

ZFS Configuration

1. ZFS RAID 1
   1. Disk: 2x SSDs
   2. Zpool: rpool
   3. Content: Proxmox install, VMs
2. ZFS RAID 5
   1. Disk: 4x HDDs
   2. Zpool: storage_backup
   3. Content: Data storage
3. ZFS RAID 6
   1. Disk: 16x HDDs
   2. Zpool: storage_main
   3. Content: Data storage

VM Configuration

1. Media VM
   1. located on rpool
   2. attach storage_main zpool
   3. attach storage_backup zpool
2. Miscellaneous VMs
   1. located on rpool

Issue:
Not sure how to attach the zpools to the Media VM. Is this the best ZFS practice? How do I attach both zpools to the VM?

What do you mean with "How do I attach both zpools to the VM"? You add the pool under Storrage tab. Then you can add VMs at the zfs pools. On VM is an Dataset.

If you want ZFS inside your VM, you'll have to passthrough all the disks and recreate the ZFS inside your VM. This involves exporting it on the host.

But i think this makes no sense. The VM is on ZFS. The only one thing is on LXC. With an mountpoint to the container.

Maybe I misunderstood, but you cannot attach zpools directly to VMs and manage them from inside. Management can only be done if the zpool is already inside, e.g. by passthrough of the disks.

If you only want to "see" the data inside your zfs filesystems, you can bind-mount them to LXC.

Thanks, I ended up using bind-mount which worked very well.

How it looks for anybody having the same issue:

root@proxmox:/etc/pve/lxc# vi 208.conf
lxc.mount.entry: /storage_main storage none bind,create=dir,optional 0 0
lxc.mount.entry: /storage_backup backup none bind,create=dir,optional 0 0

[LnxBil]

You can use mpX entries to create Proxmox VE compatible bind mounts, but yes, the lxc.mount.entry stuff also works.

The mountoption is already in the PVE Webinterface too.

For Bind-mounts? I only see "new" filesystems to bind to, not existing ones.

Yes you are right, have seen.
