[Bug 1218852] Re: [SRU] hostnames with upper case letters don't make good MON's

[James Page]

** Description changed:

  == Impact ==
  The ceph upstart configurations don't work correctly on systems with hostnames that contain uppercase characters.
  
  == Test ==
  Easiest todo with juju:
  Configured your MAAS environment with servers with uppercase hostname.
  juju bootstrap
  mkdir raring
  (cd raring; bzr branch lp:charms/ceph)
  cat > local.yaml << EOF
  ceph:
    fsid: '6547bd3e-1397-11e2-82e5-53567c8d32dc'
    monitor-count: 3
    monitor-secret: 'AQCXrnZQwI7KGBAAiPofmKEXKxu5bUzoYLVkbQ=='
-   osd-devices: '/dev/vdb'
+   osd-devices: '/dev/sdb'
    osd-reformat: 'yes'
-   ephemeral-unmount: '/mnt'
  EOF
  Deploy charm on raring using the above configuration
  juju deploy --config local.yaml --repository . -n 3 local:raring/ceph
  
  No ceph daemons will start due to missing uppercase pattern matching in
  the upstart configurations.
  
  == Regression Potential ==
  Limited; this fix is already in Saucy (and tested OK) and simple extends the range of permitted chars to include uppercase letters
  
  == Original Bug Report ==
  
  Its possible to configure a server with uppercase letters in the
  hostname: OS01-07  for example.
  
  When initializing a ceph mon filesystem this gets created OK in
  /var/lib/ceph/mon/ceph-OS01-07 - but the upstart configuration won't
  detect the mon filesystem as it contains uppercase letters.
  
  I was initially confused as running the same find command in the shell
  worked OK - but running it under the POSIX locale as happens in the
  upstart configuration causes the filesystem to be missed.
  
  I'm not 100% sure this is actually a bug - raising for discussion!
