SAVECORE(8)                                                        SAVECORE(8)


       savecore - save a diskdump image.


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

       savecore -V


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


       -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.


              The  main  directory where the crash dump files are stored. Each
              dump is put in a subdirectory whose name consists  of  the  con-
              catenation of "" and the date and time of the crash.

              This  directory  can  contain  scripts  that  are run at various
              times.  They all get passed the ip of  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.
