Post Body

Edit: Fixed this by enabling hot plug support in BIOS for the SATA ports my drives are connected to.

So I set up RAID 1 for bulk storage. When I put my computer to sleep, and then wake it up, regardless of how long I've had it sleeping(less than a minute, overnight, same behavior) my RAID is inaccessible.

If I do a full reboot, it's right there working fine.

The only information I found via Google that seemed even remotely relevant was for Windows, which obviously won't help me much.

Kernel RAID, set up with mdadm.

OS: Ubuntu 20.04

Drives: 2x Toshiba X300 Pro 4TB

I can provide whatever other specs are required to narrow this down, or the output of any relevant diagnostic commands or any configuration files.
