Compute Node password
Is there a "predefined" root password setup by Luna (or Trinityx) for the compute nodes?
I managed to provision one compute node from my head node. I am configuring slurm now, but I am suspecting some of the daemons on my compute nodes are not up, so I'd like to verify. When I try to ssh into the compute node, I'm asked for a password:
I tried the usual suspects: login/password: root/root root/ [blank password] root/admin root/password root/trinity root/luna [blank login]/[blank password] root/[Root Password]
No luck.
I scavanged in /etc/trinity/passwords/, and I tried every password listed in the directories below (note that "images" is empty)
grafana/ images/ mysql/ openldap/ prometheus/
none of the password listed in there worked. Now I am trying to access the GRUB of my compute node to change the password from there but I don't know how, and I feel like it is a pretty extreme measure (especially if I need to do that for every compute node I will provision)
Sounds like something went wrong during the image creation process. The image should have the password active from /etc/trinity/passwords/images and also a public ssh key installed for the root user. Are you sure the initial creation went as it should?
What you can always do is lchroot into the image and change the root password. Remember to pack the image after you've changed the password and reboot the node.
