Resilvering keeps restarting

[FlyingPersian]

Hello,

as posted in this thread, I've started replacing my WD Red 8TB (WD80EFAX) drives with Seagate Exos X X18 18 TB drives. I started on Thursday at 10 pm (German time) and since then the resilvering has restarted multiple times.

This screenshot is from Saturday 10 am:

This is from today, Sunday, 12 pm:

I'm opening a separate thread because most people are probably not reading up the old one where I asked for hardware recommendations.

Is this normal behavior or is something going wrong? What can I do?

It restarted again:

What I noticed in the console in the GUI that there was a message right before the resilvering re-started:

Code:

Dec 17 20:14:04 truenas (ada1:ahcich1:0:0:0): Periph destroyed

Seems like that disk (ada1) keeps detaching. That message kept repeating over and over. Seems to be an issue with that disk? Maybe a loose cable?

How do I stop the resilvering?
