Is the following behaviour expected?
  1. Two node HA LSFS storage1 on SAN90 & SAN91 (see sshot-1)
  2. Open replica manager on node #2 (SAN91) storage1
  3. Remove the replica (see sshot-2)
  4. Node #2 shows as not synchronised as expected (see sshot-3)
  5. Query? storage1 disappears entirely from node#1 (see sshot-4)
Node #2 going to unsynchronised is fine and expected but the storage disappearing entirely from node #1? All I was trying to do here was remove the replica/teardown HA.

StarWind v8 build 7145.

Cheers, Rob.

BTW - the first time I did this, the console actually crashed,

Ahh, I've repeated the crash. I think I've reported something similar before and it's to do with the user interface refresh. You have to be quick but the process to get the console to crash is:
  1. Remove replica from node #2
  2. Before the interface refreshes, attempt to remove the replica from node #1
  3. Console crashes as shown in attached
I'm assuming the crash is due to attempting to remove the replica on node #1 which has actually already removed but the user interface hasn't yet refreshed.

But the query about *why* the storage disappears from the other node still stands. So two things here: bug/query about storage disappearing and bug that the code doesn't trap attempting an operation on storage that has been removed but is still visible on the console.

Cheers, Rob.

I`ll pass this along to R&D and QA. Let`s see if we`ll be able to reproduce it.
