Gulo (including glob directory) decommissioned January 18
Very soon, January 18th, UPPMAX will decommission the file system known as Gulo. All files there will be deleted.
Right now your personal ~/glob directory is placed on that file system. UPPMAX does not backup them, so you will lose them.
If you have any files there that you want to keep you must move them NOW to
another location. Note that moving will take time too. If you want to keep using UPPMAX resources for the files there are a few options:
* if you decide that the files can be regarded as belonging to a project that you
are involved in, you can move them to that project's nobackup area.
* if you decide that the files cannot be regarded as belonging to any project
that you are involved with you can move them to your personal home directory.
Keep in mind that the total amount of storage that you can store in your home
directory is limited to 32 GB.
If you want to keep the files, but not on UPPMAX resources, feel free to move
them to a computer outside of UPPMAX.
If you do not know where to put your data, ask your local IT support provider,
normally the IT support provider of your university department
On January 18th all remaining files in the current ~/glob will be removed for
