FFS2: Enhanced Fast Filesystem (∞)

FFS2 (Enhanced Fast Filesystem) is the new filesystem by default on nearly all architectures, since OpenBSD 6.7.

Benefits:

  • FFS2 is faster than its predecessor FFS when creating the filesystem, as well as analyzing it with fsck(8)
  • FFS2 uses 64-bit timestamps and block numbers; so it is not subject to the Y2038 bug.
  • FFS2 supports very large partitions (>= 1TB, since 4.2).
