The problem:
I've been having boot issues with one of my nodes. Everything is fine up to and past GRUB:
Then this happens:
And typically I get dumped in a shell:
Towards the solution:
blkid shows both disks:
Either way, turns out the way to get the system to boot is pretty simple. Type exit and hit enter.
Looking at dmesg this is what happened:
Fixing it:
Increase the rootdelay so that the harddrive(s) have time to boot up. I think in my case the issue is that I found an ancient IDE drive which may be slow to spin up, and maybe even failing (I use it for /scratch).
Either way, edit /etc/default/grub and add rootdelay=90 (for example) to the end of GRUB_CMDLINE_LINUX_DEFAULT, e.g.
and hopefully the next time your system will boot, although slowly.

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
