→Writing your data to the global storage
== Writing your data to the global storage ==
The global storage is populated from the subdirectory "datasets/cluster" in your home directory on the CCU master node Lolth (ccu-master.inf.uni-konstanz.de, IP 134.34.224.84). If you try to login there with ssh, the shell is extremely limited for security reasons. However, you can run an rsync command to the server as follows. Assume the current directory contains a subdirectory "my_dataset" which you want to copy to the global storage on the cluster, then run
<syntaxhighlight lang="bash">
> rsync -avz --info=progress2 ./my_dataset your.username@ccu-master.inf.uni-konstanz.de:datasets/cluster/
</syntaxhighlight>
You now have a copy of your dataset on Lolth.
What happens now is that every hour, the datasets are synced to the directory "/raid/datasets/your.username" on the cluster. You can check if your data is already there by creating a test container with the following configuration:
<syntaxhighlight lang="yaml">
</syntaxhighlight>
Once it has been copied, you can mount it into any container running on the cluster. Note that every user has read access to the whole directory tree, so you can use this method to share data between users as well.
