Issue

  • Is it possible to use "--split" option of "makedumpfile" command with "core_collector" option of kdump service in "kdump.conf" file ?
  • Is it possible to split a vmcore file ( read from /proc/vmcore ) into small size files and dump them in parallel to speed-up the kdump process ?
    Eg:
              [ Kdump ] 
                  |
             /proc/vmcore [ 1TiB ]
                  |  
    [ Split and dump on disk parallely ]
                  |
    +-------------+--------------+
    |             |              |
[ vmcore1 ]   [ vmcore2 ]    [ vmcore3 ]
 [300GiB]       [300GiB]       [300GiB]
