Questions tagged [xfs]

XFS is a scalable, high-performance journaled filesystem that performs very well for parallel accesses/writes.

XFS combines advanced journaling technology with full 64-bit addressing and scalable structures and algorithms. This combination delivers the most scalable high-performance filesystem ever conceived.1

XFS is a full 64-bit filesystem, and thus is capable of handling filesystems as large as a million terabytes.1
