mkfs.lustre FATAL: Device /dev/hda10 was previously formatted for
lustre. Use --reformat to reformat it, or tunefs.lustre to modify.
It's refusing to reformat what it has identified as an already-formatted
Lustre disk. This is a safety feature to prevent you from accidentally
erasing it, thus destroying your entire filesystem. Use the --reformat
flag to force it.
man mkfs.lustre:
--reformat
Reformat an existing Lustre disk
