Harmonized user ids over medphys infrastructure

As a cludge to avoid LDAP integration, a list in this project serves as a central directory of users with associated UIDs over the medphys infrastructure cluster.

Adding a user

• Add a new entry to the UID list. Make sure you set unique username and UID fields.

Set disk server to export directory for user

• Use the same fields to add a user on disk server (kobilica):

  root@kobilca:~# adduser --uid UID username
  

• Create directory for export on disk server:

  root@kobilca:~# mkdir /tank/data/jama/username
  

• Update /etc/exportfs:

  /tank/data/jama/username 172.24.1.32(rw,sync,no_root_squash,no_subtree_check)
  /tank/data/jama/username 127.0.0.1(rw,sync,no_root_squash,no_subtree_check)
  

• Tell nfs configuration changed and check what gets exported

  root@kobilca:~# exportfs -a
  root@kobilca:~# exportfs -v
  

Import directory on processing pc

• Use the same fields to add a user on processing server (jama, vangogh, ...):

  studen@X:~# sudo adduser --uid UID username
  

• Update /etc/fstab with newly created mount:

  172.24.1.21:/tank/data/jama/username /mnt/kobilca/username nfs defaults 0 0
  

• Create the mount path, set permissions and mount it. Check whether mounts worked:

  studen@X:~# sudo mkdir /mnt/kobilca/username
  studen@X:~# sudo chown username:username /mnt/kobilca/username
  studen@X:~# sudo mount -a
  studen@X:~# df -h
