“What is the big deal about a journalling filesystem, and
how will it help me?”
“XFS is a “journalling” filesystem which SGI originally
developed for their IRIX platform.”
“A journalling filesystem is one which logs the activity of the
filesystem, thus making crash recovery much quicker.”
“This log means that in the event of a power failure, the
filesystem has a record as to what it was doing when the failure
occurred. This eliminates the need to check the entire filesystem
in the event of a failure. Instead of checking the entire
filesystem, the system simply checks the log”
“XFS is a 64-bit filesystem, which means that it can support
ridiculously large files”
“A journalling filesystem for Linux will be one less
weakness.”
