21:44:36 ovs1 kdump: Could not find a free area of memory of 8d000 bytes... locate_hole failed
Sep 26 21:44:36 ovs1 kdump: kexec: failed to load kdump kernel
Sep 26 21:44:36 ovs1 kdump: failed to start up
Oracle Linux 5, в crashkernel в grub.conf пробовал разные значения ставить, всё равно ошибка возникает. Параметры брал в том числе из официальной доки, там пишут такое:
For example, if Kdump fails to start, and the following error appears in /var/log/messages, set the offset for the reserved memory to 48 MB or greater in the command line options, for example crashkernel=128M@48M:
kdump: No crashkernel parameter specified for running kernel
The Unbreakable Enterprise Kernel supports the use of the crashkernel=auto setting for UEK Release 3 Quarterly Update 1 and later. If you use the crashkernel=auto setting, the output of the dmesg command shows crashkernel=XM@0M, which is normal. The setting actually reserves 128 MB plus 64 MB for each terabyte of physical memory.
Note
You cannot configure crashkernel=auto for Xen or for the UEK prior to UEK Release 3 Quarterly Update 1. Only standard settings such as crashkernel=128M@48M are supported. For systems with more than 128 GB of memory, the recommended setting is crashkernel=512M@64M.
Подскажете куда копать?
я конечно в глаза oracle linux5 не видел, но сцдя по этому: For systems with more than 128 GB of memory, the recommended setting is crashkernel=512M@64M. я бы это и попробывал бы
