Hi,
You can reduce LUNs from an iSCSI storage domain once it's in maintenance. [1]
On the UI, after putting the storage domain in maintenance > Manage Domain > select the LUNs to be removed from the storage domain.

Note that reducing LUNs is applicable in case the storage domain has more than 1 LUN.
(Otherwise, removing the single LUN means removing the whole storage domain).

Hello,

Is there any way to reduce the size of an iSCSI Storage Domain? I can’t seem to figure this myself. It’s probably unsupported, and the path would be create a new iSCSI Storage Domain with the reduced size and move the virtual disks to there and them delete the old one.

But I would like to confirm if this is the only way to do this…

In the past I had a requirement, so I’ve created the VM Domains with 10TB, now it’s just too much, and I need to use the space on the storage for other activities.

Thanks all and happy new year.
