When I reboot I often get the message, that one of my disks in the array is disabled. The disk works just fine, there's nothing wrong with it, but in order to get my array back, I have to rebuild it, which always takes very long.
My initial thought was that it had something to do with my storage controller, but after posting about it on reddit I think it might also have something to do with power delivery and bootup. I am using this adapter that splits 1 molex cable into 2 Sata cables.
So the reddit user recommended I increase the timeout before boot so that disks are properly detected, but I am not sure if that is what I am looking for or even where to do something like that. I found the file '/boot/syslinux/syslinux.cfg' which looks like the grub menu, and there is a 'timeout' option, so maybe if I just increase that?
