Re: Reboot after kernel grub update fails

@BShT, thanks. That confirms my suspicion. I know that Solaris makes it a minimum requirement along with the root (/) and /var partitions.

Reboot after kernel grub update fails

We, a coworker, just upgraded our system which included a new kernel, 3.10.0-1160.13.1. Then we rebooted the machine and after selecting any entry from the grub menu, the server simply hangs.
