[Rocks-Discuss] invalid users? Rocks sync users not working?
Jonathan Gough
my cluster is 32 bit, running rocks 5.3
I think that rocks sync config or rocks sync users is not working...
As root:
I have added two new users (via useradd ...)
I did rocks sync users
i did rocks sync config
i logged out of the head node and logged back in via the new users
opened a shell sorted out the .ssh passwords - null
and logged out.
as
root then I tried to change the ownership of the scratch directory on all
nodes, and I get the message:
chown: `guest:users': invalid user
logged in as the user (guest)
i tried to ssh to the nodes, and I am asked to enter a password, entering
the correct password does not work.
Any ideas on what I should try next?

I did
824 useradd -c 'Guest students' -n guest
825 passwd guest
826 exit
then logged in as guest on the front end, did the ssh key etc, hit return
logged out then back in as root
827 rocks sync users
828 rocks sync config
830 rocks run host 'mkdir /state/partition2/guest'
831 rocks run host 'chown guest:users /state/partition2/guest'
and no dice
