Description Pierre Lecomte 2019-09-10 17:32:53 UTC 
In the engine Dashboard, when navigating to :

Compute -> Data Center -> Guide me -> Configure storage

And selecting iSCSI

It is not possible to add the iSCSI storage, error reported is :

"Cannot add Storage. Discard after delete is not supported by underlying
Storage"

This was originally thought that it was only after a fresh install, but you
can reproduce this if you have already a NFS storage configured.

This reproduced consistently across various setups, including bug filer
reproducing it on his own environment.

This bug is reported as dashboard bug because attempting to perform the same
operation through the following path :

Storage -> Storage Domains -> New Domain

It works without any kind of issue(s).

I do not believe there is a point in providing logs considering how easy it
is to reproduce and the fact that it reproduces systematically.

The workaround is to use Storage -> Storage Domains -> New Domain and then
the operation succeeds.

The problem is a bug causing the value of "DiscardAfterDelete" among others not being propagated from the front end. Irrespective of the checkbox being checked or not, it behaves as if Discard After Delete was ticked.

I have a patch for this which I unit tested against 4.2.8.2-1.0.8.el7 and which stops the problem. I would like to submit it myself to Gerrit.

Verified (rhev Software Version:4.4.0-0.17.master.el7):

1. Data canter > Guide me > add more storage
2. Choose a LUN and create an iSCSI SD
3. SD was created successfully.
