SAVECORESection: Maintenance Commands (8) |
NAME
savecore - save a diskdump image.SYNOPSIS
savecore [ -p ] deviceDESCRIPTION
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.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.
