Why doesn't linux create /proc/vmcore while kernel conf marked as does?
my running kernel configuration: CONFIG_DEBUG_INFO=y CONFIG_KEXEC=y CONFIG_CRASH_DUMP=y CONFIG_MAGIC_SYSRQ=y CONFIG_PROC_VMCORE=y
my error on the kdump: kdump-config savecore running makedumpfile -c -d 31 /proc/vmcore /var/crash/201305180259/dump-incomplete. open_dump_memory: Can't open the dump memory(/proc/vmcore). No such file or directory
makedumpfile Failed. kdump-config: makedumpfile failed, falling back to 'cp' ... failed! cp: cannot stat `/proc/vmcore': No such file or directory kdump-config: failed to save vmcore in /var/crash/201305180259 ... failed!
