[SOLVED] iSCSI Storage einbinden ohne ZFS over iSCSI aber mit Snapshot-Möglichkeit

[CRMADDON Technik]

Guten Tag,

Wir haben derzeitig NAS-Geräte im Einsatz, die nur über iSCSI können, womit VMWARE kein Problem hat, Snapshots zu erstellen. Bei Proxmox geht die Snapshoterstellung leider nicht bei einem iSCSI-Storage. Es gibt zwar die Möglichkeit für ZFS over iSCSI, allerdings sind die Geräte schon etwas älter und können ZFS nicht.
Gibt es noch eine andere Möglichkeit, die Storages über iSCSI einzubinden, aber trotzdem Snapshots machen zu können?

It is possible. You have to implement a middleman server/VM in front of your iSCSI. Provision all your SAN iSCSI to that middleman, then create ZFS pool with all of the provisioned storage and configure a supported iSCSI daemon in parallel.
So your traffic will flow SAN>iscsi>MiddleMan>ZFS/iscsi>PVE.

Whether the resulting performance and likely loss of HA is worth the gained functionality is up to you to decide.

Hi,

Thanks for your replay, we could solve it through adding the storage as a LVN-Thin-Disk via shell, because the GUI doesnt recognize the storage as a free disk for some reason

Its unclear to me what exactly you did/solve. However, if you hacked an lvm-thin/snapshot solution into a shared storage requirement, you will have data corruption sooner than later.

Best of luck
