I know that EXT superblock information can be found using dumpe2fs -h /dev/sda1, but what is the XFS equivalent of this? The best I have found so far is xfs_info /dev/sda1, but this doesn't seem to produce nearly as much information as can be gotten with an EXT filesystem.

Found the answer in the official documentation. Looks like the filesystem cannot be mounted.

$ sudo xfs_db /dev/sda1
xfs_db> sb
xfs_db> p
magicnum = 0x58465342
blocksize = 4096
dblocks = 62769952
rblocks = 0

    I am guessing sb selects the superblock. p prints the superblock. – Timothy Pulliam Jan 9 '18 at 21:58
