savecore - save a diskdump image.
savecore [ -D ] [ -f ] [ -p ] [ -v ] device
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 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 "127.0.0.1" 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 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.
