[Reposted with updated info]
When I went to access my SMB share on my computer I noticed it was stuck in read only mode for some reason. So I decided to update the system via the web interface and reboot to see if that would fix it. Now when I boot the system the RAID array doesn't even mount.
I have had issues with power outages over the last few months as well which probably hasn't been helping.
I have 4 hard drvies sda sdb sdc and sdd which are in the RAID 0 array.
I'm currently running version 5.6.26-1.
I keep getting the error below when trying to mount the raid array in the file systems tab
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; mount -v --source '/dev/disk/by-uuid/6286e1c0-da5a-481e-98e5-5efc57f0463c' 2>&1' with exit code '32': mount: /srv/dev-disk-by-label-CorePoolData: /dev/md0 already mounted or mount point busy.
Here are the results of a few other commands as suggested on the RAID questions template.
