So after a hard shutdown and physically disconnecting the disks I was able to prevent autostart under disk settings to prevent the stuck on mounting issue and then reconnected the sata cables and was able to start in maintenance mode. In Maintenance mode was able to perform an xfs_repair -L on the corrupted disk and the array started up with no lost data. What an adventure. I didnt realize how much I used my server until it wasnt available. Next purchase will be a couple 22tb drives in another box just in case I go down again. Thanks for the help to the all on this thread.
