Are you running a 64 bits kernel? A 32 bits kernel won't be able to use
a filesystem bigger than 16 TB.
You need to install the xfs-progs too, to have mkfs.xfs.
To format a 300TB xfs, basically just do
mkfs.xfs /dev/whatever
However you'd better configure your filesystem to match the underlying
device. You must be using some sort of RAID array; you should do it
this way:
mkfs.xfs -d su=<value>,sw=<numberofdataDisks> /dev/whatever
Where <value> is the RAID array stripe size (in bytes, or append a k or
m accordingly) and <sw> the number of data disks (removing parity and
spare drives from the total).
