Advice on storage

[dignus]

Hi all,

We're going do deploy a proxmox cluster soon. I'd like to get some advice from the people who are using it on what storage method is best. We have a ZFS cluster on the netwerk, so I can use both NFS & iSCSI. What would be the configuration to use so that I'm able to use most of the functionality in proxmox?

Do you want to store Data on the Proxmox nodes ? (If so, what amount/Type of Disks you using per node? - how many nodes ?)
What type of Data you wanna store (in general)?
How much of said Data ?
Whats the connectivity of the Proxmox nodes like ?

How much of said Data ?

> Roughly about 10 TB.

Whats the connectivity of the Proxmox nodes like ?

> Dual 10 gbit (LACP)

What OS runs your ZFS cluster?

Linux, it's a Zetavault setup.

For using your ZFS cluster read this: https://pve.proxmox.com/wiki/Storage:_ZFS_over_iSCSI

That would create issues with Zetavaut itself. Can I make use of all proxmox functionality when I use NFS? Cloning, snapshots etc ?

Check out this thread:

Mir afaik answered your question completly

A few things making this impossible:
1) NFS does not understand and support ZFS file attributes and ACL
2) NFS does not support atomic writes which brakes basic and fundamental security and integrity in ZFS
3) NFS does not support partitions

Add to the above that it will be plain stupid since it contradict and brake everything which ZFS stands for.

edit: never heared of zetavault before, but their website states they support iscsi.
