[Rocks-Discuss] 2 compute nodes require a password for ssh
Jonathan Gough
2 nodes that have never given me problems whatsoever stopped letting me ssh
in. I didn't realize this until the nodes stopped accepting Jobs from PBS.
Things I have tried:
rocks sync users
I shutdown both nodes and restarted - synced again.
still nothing. any ideas?

execute rocks sync users.
i.e. umount /home/<user> first
I can't remember if this applies to /share/apps as well. Better
umount that as well before issuing rocks sync users.
At least that is what I do in ROCKS 4.3. :)

What error do you get if you try to ssh to the nodes, a time out, a
message about port 22 not accepting requests? Can you ping the nodes? Is
it just your user who can't ssh / login, or is root not able to as well?
Have you hooked up a monitor / keyboard to the nodes to ensure that they
are actually successfully booting?
When you say you rebooted the nodes, did you hit the reset switch /
power button, or log in locally as root and issue the shutdown command?
As Jonny #5 would say, "need more input!"

isn't found.
i can log in as root without a password

and check it, and possibly start it:
# ssh compute-X-Y service autofs status
If it's not running:
# ssh compute-X-Y service autofs start
You can also try "service autofs re-start".

/etc/auto.home file. You should have entries for each of your users:
jeremy bcf.local:/export/home/user/&
If you do not, you can repopulate that file using dbreport, copy it to
that node and restart autofs.

an easier way to do the same this is, on the frontend, execute:
# rocks sync config
that regenerates all files under the control of 411 (of which
/etc/auto.home is one), broadcasts a message to all compute nodes that
tells the compute nodes to get the files under 411's control, then
restarts autofs on all compute nodes.

or
# rocks set host pxeboot compute-0-0 action=install
And PXE boot the node (just reboot it, if you have PXE selected as the
first in the boot order in the BIOS).
or
Punch the power button / reset button, or unplug the node. Rocks
re-installs by default if a node goes down ungracefully.
