[kittiwat]

Hello,

I'm looking Solution PVE storage types.
Setup Proxmox Cluster(HA) with SAN Storage Fibre Channel.


I Setup LVM Storage types missing problem : Doesn't over-commit in the LVM space VM.
I Setup LVM-THin Storage types missing problem : Doesn't Migration VM

What should i use Storage types?


Sorry, My English isn't that good.

Hi,

you have to use LVM because Thin-LVM is not working as shared storage.
Only LVM can be used as shared Storage on FC.
So you can't overcommit.

Maybe you can do it in storage system with space guarantee or something like this

As @wolfgang already said, you must use LVM (without thin) in a FC setup.

We played around with various cluster filesystem solutions to have a file-based storage and wanted to use QCOW2, snapshots, over-committing and such, but there was, unfortunately, no viable solution for this.
