== Configuration Parameters ==

'''Configuration parameters in <tt>/etc/ws.conf</tt>:'''
* <tt>duration</tt> - Maximum lifetime in days
* <tt>maxextensions</tt> - Number of times a workspace can be extended
* <tt>keeptime</tt> - Days to keep expired workspaces before final deletion (typically 7-30 days)
* Released workspaces have a shorter grace period (~1 hour) regardless of <tt>keeptime</tt>

'''Note:''' Check your specific cluster documentation for current quotas and settings, as they may change. Use <tt>ws_list -l</tt> to see available filesystems and their properties on your cluster.

= Checking Workspace Quotas =

The command to check workspace quota usage varies by cluster and filesystem:

== Lustre-based clusters ==

'''bwUniCluster 3.0, JUSTUS 2:'''

$ lfs quota -uh $(whoami) /lustre/work # or appropriate workspace path
$ lfs quota -uh $(whoami) /pfs/work9 # bwUniCluster 3.0

== NEMO2 (Weka filesystem) ==

$ nemoquota # Shows HOME and workspace quotas
$ df --si $(ws_find workspace_name) # Check specific workspace

== Helix (IBM Spectrum Scale) ==

$ workquotainfo # Shows workspace quota info

== BinAC2 ==

* No quota limits enforced on workspaces
* Check available space with <tt>df</tt> command

== General tip ==

Always check disk usage before large data operations to ensure sufficient space is available.
