=== Journal === JFS is a [[journaling file system]]. Rather than adding journaling as an add-on feature like in the [[ext3]] file system, it was implemented from the start. The journal can be up to 128 MB. JFS journals metadata only, which means that metadata will remain consistent but user files may be corrupted after a crash or power loss. JFS's journaling is similar to [[XFS]] in that it only journals parts of the [[inode]].<ref>{{cite web|title=JFS journal|publisher=OSDIR|author=David Kleikamp|url=http://osdir.com/ml/file-systems.jfs.general/2004-12/msg00025.html|access-date=July 7, 2008|archive-url=https://web.archive.org/web/20160303225646/http://osdir.com/ml/file-systems.jfs.general/2004-12/msg00025.html|archive-date=March 3, 2016|url-status=dead}}</ref>
