Errors during drive rebuild

I woke up this morning and couldn't get my server to boot.  It went offline sometime during the night.  After messing with the flash drive configurations and the cables I finally got it to reboot.

Once it rebooted it told me that Drive 4 was not valid so now it is performing a rebuild.

During the rebuilld I am seeing the following errors and I'm wondering if they are anything to worry about.

Thanks for the help.
