List write back status of volumes

[terago]

I can't enable or disable it. Under "CONFIGURATION - iSCSI Target manager - Targets", when selecting a target, it shows the logical volume associated with the target (example: lv0001), but the WB option is greyed out (as is RO) and I can't select or deselect it.

How can I show the status of each target or volume and it's current writeback status?

This is correct, what you need to do is click on the "-" sign not the "+" sign then enable the WB option then click on the "+" sign to enable both the WB option and the LUN.

if you click the minus sign and disable the LUN, you can change the WB setting.
To see the current status of the volumes, open the logs and look at the dmesg files.
To se the current status of the targets, you can see that in the GUI (checked, or unchecked).
