Hi guys, Have a nasty issue to report here. I have a RAID10 btrfs configuration where I was replacing one disk for another. Unfortunately, during the replace, it seems like one of my disks (not in the array) stopped getting powered (looks like the cable was loose) and caused the machine to lock up.
Since then, I have not been able to boot normally with the array in fstab. I’ve
passed along “recovery” in my fstab line and have taken to editing in the fstab
line to mount, then immediately commenting the line out (otherwise, the machine
will not boot successfully; it’s a headless box, so this is painful).
It seems to try to continue the replace, but dies shortly after mounting with
