Files on UPPMAX¶

Disk storage guide¶

Where are my files? (Or, what are the different file systems?)¶

You have access to the same home directory regardless of what cluster you have logged into. Here you store your private files.

All projects also have a central storage area under the /proj/[project id]/ directory path, i.e. when you first login to UPPMAX, you will see your home directory, so you will have to change to the project directory if you want to transfer project data files.

Also note that UPPMAX uses different disk quotas on your home directory and other areas you have access to (like the project folder). Use uquota to see who much disk space you use.

Your private files¶

When you log in to UPPMAX for the first time you only have the following files created by the system:

$ ls -la
total 68
drwxr-x---  7 user     uppmax 4096 Jun  2 23:11 .
drwxr-xr-x 19 root     root      0 Jun  9 13:16 ..
-rw-r--r--  1 user     uppmax   24 Jan  9  2008 .bash_logout
-rw-r--r--  1 user     uppmax  435 Apr 21  2008 .bash_profile
-rw-r--r--  1 user     uppmax  446 Jan  9  2008 .bashrc
drwxr-xr-x  2 user     uppmax 4096 Jan  9  2008 bin

-rw-r--r--  1 user     uppmax  237 Jan  9  2008 .emacs
drwxrwxrwx  1 user     uppmax   14 Jun  2 11:05 glob
-rw-r--r--  1 user     uppmax  120 Jan  9  2008 .gtkrc
-rw-r--r--  1 user     uppmax  279 Apr 21  2008 .login
drwx--S---  2 user     uppmax 4096 May  2  2008 private
-rw-r--r--  1 user     uppmax  307 Apr 21  2008 .profile
-rw-r--r--  1 user     uppmax  220 Jan  9  2008 .zshrc

The files starting with a . (i.e. a dot or period) are hidden files. These are commonly startup scripts or configuration files.

The default permission of your home directory is 750, i.e. you can do everything, people belonging to the same group can read and execute your files and other people can not do anything.

Also note the private sub-folder: here you can put files that you want only you, and no one else, to be able to access. Each day we have a job that ensures that all users private folders still can't be accessed by anyone else, even if the permissions somehow accidentally would change.
