RAINBOF: jop, da se to udelat i po remount,ro ale radsi bych si na to vypadecek udelal :)
-j Add an ext3 journal to the filesystem. If the -J option is not specified, the default journal parameters will be used to
create an appropriately sized journal (given the size of the filesystem) stored within the filesystem. Note that you
must be using a kernel which has ext3 support in order to actually make use of the journal.
If this option is used to create a journal on a mounted filesystem, an immutable file, .journal, will be created in the
top-level directory of the filesystem, as it is the only safe way to create the journal inode while the filesystem is
mounted. While the ext3 journal is visible, it is not safe to delete it, or modify it while the filesystem is mounted;
for this reason the file is marked immutable. While checking unmounted filesystems, e2fsck(8) will automatically move
.journal files to the invisible, reserved journal inode. For all filesystems except for the root filesystem, this
should happen automatically and naturally during the next reboot cycle. Since the root filesystem is mounted read-only,
e2fsck(8) must be run from a rescue floppy in order to effect this transition.
