lvm-thin over iscsi on the cards any time soon?

[Sp00nman]

Hi Proxmoxers,

The only issue preventing our organisation from adopting Proxmox to replace our legacy VMware stack is that currently lvm-thin provisioning doesnt work over iscsi.

Is this something that is being looked at in the development roadmap?

Looking forward to your repsonses.

Hi @Sp00nman ,
You can use LVM thin on iSCSI disk now, as long as that disk is presented to one node, and one node only. It cannot be shared storage.

Guaranteed data corruption prevents this combination of technologies to be placed on roadmap.

Are you looking for shared storage with snapshot and thin provision support to align with your existing infrastructure?

Hi bbgeek - thank for the prompt response.

Yes that is correct - we need thin provisioned shared storage for our use case - snapshots arent essential as we can do incremental backups using PBS

Your present options are:
Retrofit SAN with ZFS head for ZFS/iSCSI.
Implement one of the OSS cluster aware filesystems.
Refresh your SAN with PVE-compatible one.
If your investment in current SAN is significant and capacity is on the larger size, reach out to PVE storage solutions partner, they may be able to help you.

Good luck.
