SAVECORE(8)                                                        SAVECORE(8)



NAME
       savecore - save a diskdump image.

SYNOPSIS
       savecore [ -D ] [ -f ] [ -p ] [ -v ] device

       savecore -V

DESCRIPTION
       savecore  reads data from the disk dump partition specified by the device argument,
       and creates a vmcore file in a  directory  named  /var/crash/127.0.0.1-  timestamp.
       The timestamp portion of the directory name indicates the date and time when system
       crash occurred.  The vmcore file can be analyzed by the crash(8) utility.

OPTIONS
       -D     delete dump from the dump partition after saved.

       -f     Create a vmcore file forcibly even if dump directory exists.

       -p     Display progress for creating a vmcore file.

       -v     Provide some verbose outputs.

       -V     Show version information and exit.



FILES
       /var/crash
              The main directory where the crash dump files are stored. Each dump  is  put
              in  a  subdirectory  whose name consists of the concatenation of "127.0.0.1"
              and the date and time of the crash.

       /var/crash/scripts
              This directory can contain scripts that are run at various times.  They  all
              get  passed the ip of 127.0.0.1 as the first argument, and each one gets the
              directory that the dumpfile is written to as the second argument.

              diskdump-nospace - This is run when there is not enough disk space  for  the
              dump  of  the  crashed  machine. If this script exits with a non-zero return
              value, savecore will try once again (but only once) before giving up on  the
              dump.  If  this  script  exits  with a zero return value, savecore will exit
              without performing a dump.  The default script simply sends a  mail  message
              and  exits  with  a  zero  value,  but  it can be enhanced to try to free up
              diskspace and return a non-zero value.
