EX4100 Stuck on Rebuilding

Hello Everyone,

i had an issue with my EX4100: Drive 4 failed and degraded.

The WD-Support told me to turn it off, plug out all drives and replug them in the same order.
I did this yesterday evening and it started to rebuild the RAID10.

This morning it said: Rebuilding Drive 4 (35%,1905438 M)
The percentage-value has been stuck at 35% all day, the minute-value is changing though. But i can not hear or see any activities on the NAS.

I actually don’t believe this ever ends. Or is that somehow normal?

What shall i do?

Luckily i have a recent backup!

Thank you
