Your storage:
Note that your Your data on Neon will only be stored until March 1, 2019. Please be advised that the data being copied from Neon home/scratch to a local machine will have to be decompressed, and may end up being larger than what it showed on on Neon. When copying data from Neon → Argon homes, your storage for your Argon home cannot exceed 1TB of data. Reminder that the inability to submit jobs occurs once the storage quota exceeds 90%. To check your current storage, use the command below:
If you receive a message stating that your home account has reached its quota, and you cannot fill it any farther, you must remove some large files from your home directory. Sometimes, the rm command will fail with a...
mmessage of "Quota has been reached." If this happens, here is what you can do to correct the issue.- Pick a large, unwanted file to remove.
Copy the contents of /dev/null to this file. This will basically make the file a pointer to NULL values with a size of 0.
cp /dev/null name_of_file_to_delete
Once you have done this, you can use 'rm' as you normally would to free up more space.
When copying large amounts of data from Neon to Argon-nfsscratch, remember that data that is placed there will be cleared 60 days later as part of our cleaning policy. The scratch cleaning policy on neon-nfsscratch will be removed on January 7th so that no data will be removed by that policy prior to the host being decommissioned on March 7.

Methods to obtain data:
The login to Neon will be going away on January 7th so it is advised against using relying on mounting your home account to transfer storage. The preferred method will be using data.hpc.uiowa.edu.

| /hpchomes/<cluster>/<hawkid>/ | Your HPC home directory. For <cluster>, this is either "neon" or "argon" |
| /Dedicated/<sharename>/ | Dedicated shares |
| /Shared/<sharename>/ | Shared shares |
| /nfsscratch/<cluster>/ | The NFS scratch filesystem. For <cluster>, this is either "neon" or "argon" |
Fetch (mac only): getting errors. screenshots to comeThis will mount your Neon account. Follow the table above for setting a path to get your data from shared shares, dedicated shares, or from nfsscratch. In this case, the path below is just for home directories. You can then execute "get" commands to pull your data from Neon onto your local workstation (keep in mind the compression aspect).
Note: This method will require a Duo authentication.
WinSCP (windows only): getting errors. screenshots to come. This will mount your Neon account. Follow the table above for setting a path to get your data from shared shares, dedicated shares, or from nfsscratch. In this case, the path below is just for home directories. The server will just be data.hpc.uiowa.edu - we have to manually link it to the proper directory. Once connected, you can just drag and drop files from Neon onto your local workstation.
After you authenticate with Duo, you will notice your path looks like this. Click the very first character, the forward slash, twice. It will open a "Open directory window" where you then can then enter the path from the above table for dedicated, shared, or nfsscratch.
