The dump area is configured.
Confirm that hard disk
has enough free space before collecting the memory dump.
After OS installation, do a setting of kdump as following:
a.
Change the setting of Grub's parameter "crashkernel" to "256MB".
(example)
Edit the file “/etc/grub.conf” as following:
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux Server (<kernel revision>.x86_64)
root (hd0,0)
kernel /vmlinuz-<kernel revision>.x86_64 ro root=UUID=xxxxxxxx-xxxxxxxxxxxx-xxxxxxxxxxxx ro
rd_NO_LUKS LANG=ja_JP.UTF-8 rd_NO_MD SYSFONT=latarcyrhebsun16 KEYBOARDTYPE=pc KEYTABLE=jp106
rd_NO_LVM rd_NO_DM crashkernel=256M
initrd /initramfs-<kernel revision>.x86_64.img
b. Change setting of kdump to work with small memory
- Case of Red Hat Enterprise Linux 6.4
Add setting of cp command to core_collector of /etc/kdump.conf file
Edit the file "/etc/kdump.conf" as following:
core_collector cp --sparse=always
extra_bins /bin/cp
[Note] makedumpfile command cannot be used for core_collector because the command uses big memory
and system may run out of memory.
- Case of Red Hat Enterprise Linux 6.5
Any changes is not needed for core_collector
[Note] RHEL6.5 improves memory usage of the makedumpfile command.
