[Lustre-discuss] Completely lost MGT/MDT

[Andrus, Brian Contractor]

Basically, I was adding capacity to a system while doing a fresh install. Turns out /dev/sda which used to be the disk in the bottom slot became the disk in the top slot instead.
That happened to be where the MDT was, which was promptly repartitioned and formatted.

Not exactly something I was expecting....
