    Command:

    jfs_tune

    
    
    
    

    SYNOPSIS

           jfs_tune [options] device
    
    
    

    DESCRIPTION

           jfs_tune  adjusts  tunable  parameters  on  a  Linux JFS file system or
           external journal.  jfs_tune must be run as root.
    
           device is the special file name  corresponding  to  the  actual  device
           (e.g. /dev/hdb1) on which a JFS file system or JFS external journal has
           been created.
    
    
    

    OPTIONS

           -J device=external-journal
                  Attach the JFS external journal located on  external-journal  to
                  the JFS file system on device.
    
                  The  external  journal  must already have been created using the
                  command.  More than one file system may share the same  external
                  journal.
    
                  mkfs.jfs -J journal_dev external-journal
    
                  Attach the external journal to the file system by using the com-
                  mand
    
                  jfs_tune -J device=external-journal device
    
                  Instead of specifying a device name  directly,  external-journal
                  can  also  be  specified by either LABEL=label or UUID=UUID (Use
                  jfs_tune -l device to display a journal  device's  volume  label
                  and UUID.)
    
           -l     List  the  contents  of  the JFS file system or external journal
                  superblock that resides on device.
    
           -L volume-label
                  Set the volume label of the JFS file system or external journal.
                  JFS labels can be at most 16 characters long; if volume-label is
                  longer than 16 characters, jfs_tune will truncate it and print a
                  warning.  The volume label can be used by mount(8), fsck(8), and
                  /etc/fstab(5) (and possibly  others)  by  specifying  LABEL=vol-
                  ume_label instead of a block special device name like /dev/hda5.
    
           -U UUID
                  Set the universally unique identifier (UUID) of the file  system
    
                  See uuidgen(8) for more information.
    
           -V     Print version information and exit (regardless of any other cho-
                  sen options).
    
    
    

    EXAMPLES

           Set a randomly-generated UUID for the JFS file system on the 3rd parti-
           tion of the 2nd hard disk, and view the resultant superblock:
    
                  jfs_tune -l -U random /dev/hdb3
    
           Attach an already existing external journal on a device labeled  JFSLog
           to a JFS file system on /dev/hda8:
    
                  jfs_tune -J device=LABEL=JFSLog /dev/hda8
    
    
    

    REPORTING BUGS
