I attempted to upgrade a disk last weekend. I replace Disk 5 with a 8TB drive and restarted the array. After the rebuild started, I noticed that Disk 4 was showing up as valid (green) but also as 'unmounted'. I panicked and cancelled the rebuild, powered down, then re-installed the old Disk 5. Both drives showed up as unmountable. I ran xfs_repair on both drives. Drive 4 doesn't get past phase 1, but I managed to 'fix' Drive 5. I was hoping to rebuild Drive 4, but Drive 5 now shows up a a "New Device" and I'm unable to start the array. Is there any way to force Unraid to accept Disk 5 as being valid? I've attached a screen shot of the array configuration and the diagnostic zip file.
