NAME

       jfs_logdump - dump a JFS formatted device's journal log

SYNOPSIS

       jfs_logdump [ -a ] device

DESCRIPTION

       jfs_logdump  dumps the contents of the journal log from the specified JFS formatted device
       into output file ./jfslog.dmp.

       device is the special file name corresponding to the actual device from which the  journal
       log will be dumped (e.g.  /dev/hdb1 ).

       jfs_logdump must be run as root.

OPTIONS

       -a     Dump  the  entire  contents  of  the  journal  log  instead  of  just the committed
              transactions since the last synch point.

EXAMPLE

       Dump the entire JFS journal log  from  the  3rd  partition  of  the  2nd  hard  disk  into
       ./jfslog.dmp:

              jfs_logdump -a /dev/hdb3
