Snapshot option greyed out

[kazi]

I'm having an issue with my proxmox server and snapshots - the option is greyed out and i cant work out why? any suggestions?

Its a linux KVM running on a SAN.
ALL my VMs are qcow2 image.


Here is my /etc/pve/st
orage.cfg file

Are you using a filesystem that supports snapshots, like LVM-Thin or ZFS?

I am using ZFS

Your configuration file shows that you:
- have iSCSI storage called "Proxmox-iscsi"
- have LVM THICK storage that depends on "Proxmox-iscsi" and is marked shared
- have local LVM-thin pool

As pointed out by @ronaldst for PVE to allow snapshots for a specific VM - it must be located on storage that supports the snapshots.
The only two storage pools in your configuration that could support snapshots are "local-lvm" and "Backup-VM".

Since your "local" is not marked "images" - you cant place disk images there. So you are down to "Backup-VM" which is the only place where you can place qcow at this time.

So in summary: In PVE direct iSCSI storage does not support snapshots (or any metadata operations). LVM Thick does not support snapshots. You are probably mistake about disk image format.

Which disk image format do I need to mention? This is my test environment. I will do PROD and Pre-PROD

I am confused by your question. There is nothing you can do with SAN+ISCSI+LVM (thick) to get snapshots.
You can enable "images" on "local" and create/store disks as qcow. That will give you snaphots, but it wont change anything about your SAN.
