How to grant Samba access on supported clusters

Currently, Samba is supported on Hive and Franklin.

Hive

Hive's Samba access is currently controlled through Puppet. At the top of data/nodes/samba.hive.hpc.ucdavis.edu.yaml, there is a hpccf::samba::users: section with a list of Hive users that will have Samba passwords created for them by Puppet.

  1. Verify the user is on Hive and is in a group that has a Samba share.

    • As of this documentation publication, the only group is:

      • metabolomicsgrp

        • Access IP: 128.120.208.42

    • You can verify on samba.hive with grep 'grp\]$' /etc/samba/smb.conf:

    Note 
    ┌─omen@samba.hive: ~
└─1 $ grep 'grp\]$' /etc/samba/smb.conf
[hpccfgrp]
[metabolomicsgrp]

  2. Edit that file to add the new user's Login ID and ticket # number to the list under the appropriate group comment.

    hpccf::samba::users: 
    hpccf::samba::users:
# hpccfgrp
- mclewis
- omen
# metabolomicsgrp
...
- newuserhere # INCNNNNNNN

  3. Commit the changes to git.

  4. Push the changes to GitHub.

  5. Run puppet on puppet.hive.

  6. verify ~{newuserhere}/samba-password exists, update the ticket with wording like:

    INC wording 
    You have been added to Hive's Samba. Your password for this service can be found in "[code]<code>~/samba-password</code>[/code]" on Hive. The share is "[code]<code>metabolomicsgrp</code>[/code]" and the host IP is 128.120.208.42.

Let me know if you have additional questions or run into any issues.

    Note: the IP may depend on the group.

TODO: automate through Cheeto

This entire process should be moved into Cheeto with Puppet applying the changes. This requires Cheeto to support Quobyte, and probably additional development.

Franklin
