Key Operations

Show filesystem info	`xfs_info /mount/point` or `xfs_info /dev/sdXN`
Create filesystem	`mkfs.xfs /dev/sdXN`
Create with label	`mkfs.xfs -L mylabel /dev/sdXN`
Repair (unmounted)	`xfs_repair /dev/sdXN`
Forced repair (corrupted log)	`xfs_repair -L /dev/sdXN` — zeroes the log; last resort
