Booting x64 node into non-cluster mode after crash
One of the problems with x64 when the node is crashing continuously is the unavailability of the non-cluster mode in the GRUB menu.
To workaround the problem, when the grub menu is displayed, choose "e" to edit the regular boot option, "e" to edit once again and add a -x option at the end and then press "b" to continue booting. This problem doesn't occur if the node is rebooted with the
#reboot -- -x
command when it is in cluster mode (you can find a reboot_transient state added to the menu). The problem I suspect is due to the boot-archive file on x64.
