Mode=REISER Menu: [Linux Reiser journaled File System]

Allocation map display

From main menu: Mode=REISER -> Allocation map display

Display a pseudo-graphical map of used versus free sectors in the filesystem

Menu item screenshot(s)


    Display a usage map for the currently selected disk or filesystem

    A pseudo-graphical map of the disk or partition allocation is
    displayed, showing the distribution of data over the object

    This is also an indication for the amount of unused sectors in
    the object, that are beneficial to 'SMART-SECTOR' optimizations
    in imaging and cloning operations.

    The percentage of used sectors are displayed as a percentage at
    the end of the line, and a total usage percentage and size is
    shown just after the map itself.

    For filesystems that support resizing, the limits for resizing
    are shown after the map itself.

Make THIS partition Active

From main menu: Mode=REISER -> Make THIS partition Active

Make the currently selected PRIMARY the 'active' partition for MBR/BIOS boot


    This will make the currently selected PRIMARY partition the
    ACTIVE one for the disk.

    There should only be a single active partition on every disk.
    When the system starts, the BIOS will usually boot from
    the ACTIVE partition on the first disk.

    In IBM BMGR/LVM terms the active partition is called STARTABLE.

Delete THIS partition

From main menu: Mode=REISER -> Delete THIS partition

Delete the currently selected partition from the partition tables


    This will delete the partition that is currently selected to be
    deleted from the partition-tables. This will result in the space
    occupied by the partition becoming FREESPACE that can be used
    again to create new partitions.

    For primary partitions on LVM-systems, the related LVM-information
    is cleared as well, to avoid consistency problems later when a new
    partition is created at the same position.

Display/Edit UUID string

From main menu: Mode=REISER -> Display/Edit UUID string

Display and optionally edit the (Linux) UUID string value in the superblock


    This will display and optionally update the UUID string in
    the filesystems superblock.

Display Superblock

From main menu: Mode=REISER -> Display Superblock

Display the SUPERBLOCK structure for the currently selected filesystem


    This will display the contents of the filesystem superblock
    in a textual format matching the current filesystem type.

Reselect whole disk, FDISK

From main menu: Mode=REISER -> Reselect whole disk, FDISK

Unselect filesystem, reselect the same/first disk; enables Mode=FDISK menu

Menu item screenshot(s)


    This will UNSELECT the current object/filesystem, and reselect a
    whole physical disk, either the same disk as the partition was on,
    or the first disk present in other cases.

    This is a quick way to change to 'Mode=FDISK' and work on
    disk-level issues
