Hi, I have some running VM on it, this isn't easy... If I remove that LUN from the SD, what will happen to the disk defined in that SD? will they get lost?

We also observed that the serial has changed on the corrupted SD/LUN. Is the serial calculated or read somewhere? Would it be possible to inject the missing values in the engine DB to recover to a consistent state? Thanks for any help.

To synchronize them, please move them to maintenance and then activate. can you put them in maintenance and then activate them back so it will be synced? I guess that it is out of sync, that's why the "Add" button appears to already added LUNs On Tue, Jul 14, 2020 at 4:58 PM Arsène Gschwind <arsene.gschw...@unibas.ch<mailto:arsene.gschw...@unibas.ch>> wrote: Hi Ahmad, I did the following: 1. Storage -> Storage Domains 2 Click the existing Storage Domain and click "Manage Domain" and then I see next to the LUN which is already part of the SD the "Add" button I do not want to click add since it may destroy the existing SD or the content of the LUNs.
