Hi guys,

I already started to test Proxmox VE 9 with underlying Purestorage SAN and shared LVM on top of a SAN Lun. HA features for VMs are working fine with this storage type. I also started to test LVM snapshot feature snapshot-as-volume-chain. In the web-ui it is still commented with "Tech Preview" but in the Proxmox VE documentation it's not marked as such any longer.
So I'm wondering if its now officially supported?

- https://pve.proxmox.com/pve-docs/chapter-pvesm.html#_storage_types

Best regards

Frank

Hi, Proxmox VE 9.1 has been released: https://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_9.1.

Unfortunately snapshots as volume chains are still just a technology preview: https://pve.proxmox.com/pve-docs/chapter-pvesm.html#pvesm_lvm_config

I will test the LVM snapshot feature further after updating my cluster to Proxmox VE 9.1. In the current version there is a bug when deleting disks with snapshots enabled. It takes ages to wipe the disk bacause the current implementation has a limit of 10 Mb/s write speed on this specific disk action.

the bug was fixed and wiping was improved in Proxmox VE 9.1 thanks to @spirit:

Rolling out a new feature set that impacts data handling is naturally a significant undertaking. It carries a different risk profile than, say, introducing a new GUI option. I imagine the team wants to ensure that a few remaining details are fully worked out before releasing it.

For example, this recent discussion highlights some of the considerations involved: https://forum.proxmox.com/threads/u...emu-cache-none-in-proxmox.175933/#post-816074

I’m confident the feature will make its way into a release once the team feels it’s ready.

Cheers
