Hi Roland, Thank you for your answer and time. I've been looking for the auto-resync-after-disable parameter without any luck. I'm using this command to search for it `linstor controller drbd-options -h`. So it seems that I'll have to build a resync chain since my physical resources aren't able to handle the full sync without affecting the business app.
