[Users] Storage domain issue iSCSI

[Simon Donnellan]

Hi Yeela, Shu,

Many thanks for your replies.

I'm aware of the one type rule, the two NFS shares you noticed are the ISO
share and an export store. (I'm unable to find a way to create these as
iSCSI type)

The UUID of the master iSCSI domain is f1b40ecc-b6a9-44e7-
92cb-0fdf445e3175

it's name in the gui is "512gb2"

I too believe there is a meta data corruption, is there any way to get my
systems back up and running?

Kind Regards

Simon
