  1. Of course its been solid by 91degrees · · Score: -1, Flamebait

    Journalling file systems are only needed when an OS is powered down unexpectedly. It's totally impossible for thois to happen with Linux for the simple fact that the OS isn't written by MS.

  2. Still same old 2GB limit? by king_ramen · · Score: 0, Flamebait

    The biggest flaw of ext2 is the minisiclue 2GB file size limit, which is fixed in ReiserFS and XFS. Does ext3 still have this 1991-ish limitation? It really caused trouble for large databases and full bacukups of live systems onto the filesystem. I never reboot my machines, so journaling is not nearly as important as speed and file size.
