XFS combines advanced journaling technology with full 64-bit addressing and scalable structures and algorithms. + Journaled 64-bit filesystem with guaranteed filesystem consistency. + XFS supports filesystem growth for mounted volumes, allows filesystem "freeze" and "thaw" operations to support volume level snapshots, and provides an online file defragmentation utility. + XFS supports user and group quotas. XFS considers quota information as filesystem metadata and uses journaling to avoid the need for lengthy quota consistency checks after a crash. + For Linux 2.6 and beyond, when using 64 bit addressing in the block devices layer (CONFIG_LBD) and a 64 bit platform, filesystem size limit increases to 9 million terabytes (or the device limits). For these later kernels on 32 bit platforms, 16TB is the current limit even with 64 bit addressing enabled in the block layer. This package contains filesystem manipulation and support programs. Very loosely based on the FreeBSD port (I took the MASTER_SITES from there).
