Globus Paths, Permissions, Storage Allocation

Globus default directory

If you point Globus to an Endpoint where you have an account, it will open a single panel pointing to the path of your home-directory there, displayed as '/~/'.

 On NeSI's Māui/Mahuika cluster this means:

filesystem visible to Globus storage persistent Globus usage
/home/; or '/~/' yes (default) 20GB yes possible, not recommended
/nesi/nobackup/<project_code> yes yes no yes
/nesi/project/<project_code> no - yes no


The /nesi/nobackup filesystem for Globus file-transfers and sharing (which we'll call the nobackup filesystem henceforth) is

  • not persistent
  • not backed up

Every project has a large quota on the /nesi/nobackup filesystem for a short period of time.

As the filesystem becomes full, files will be deleted according to their age. Move your files off the nobackup filesystem if you want a persistent copy of them. See the NeSI documentation on  filesystems for more information.

Performing Globus transfers to/from Māui/Mahuika

  • if transferring files off the cluster, move/copy files onto /nesi/nobackup first
  • sign in to Globus and navigate the file manager to the nobackup path associated with your project (viz. /nesi/nobackup/<project_code>)
  • click the "two-panels" area in the file-manager  and select the other endpoint
  • select source of transfer
  • transfer data (from), using the appropriate "start" button
  • if transferring files onto the cluster, move files off /nesi/nobackup after transfer

Tips

1.  Globus bookmarks can be created for /nesi/nobackup paths, and these bookmarks pinned.

2.  Symbolic links can be created in your project directories and nobackup directories to enable easy moving of files to and fro.
To create a symbolic link from a first to a second directory and vice-versa (using full paths for <first> and <second>):

$ cd <first>
$ ln -s <full_path_to_second> <alias_to_second>

$ cd <second>
$ ln -s <full_path_to_first> <alias_to_first>

Here you substitute convenient values for these aliases.
After you do this, there will be an alias listed in each directory which points to the other directory. You can see this with the ls command, and cd from each to the other using its alias.
