-Some important notes about the CEP1 and CEP2 home directories:+===== Wiki =====
  
-Please be aware of the following:+You will have to register. See [[:start|The LOFAR wiki start page]].
  
-  * You share your home directory with ~ 275 neighbors  
-  * The observe system depends upon good availability 
-  * The pipeline runs on CEP2 also depend upon good availability 
-  * Home directories are subject to backup operations, more volume means more vulnerability  
-  * Moving large volumes on home-directories on head nodes can stall all cluster-nodes! 
-  * Keep your volume below 100GB (preferably less) 
-  * Use ``rsync --bwlimit=5000`` (5 MB/s) when coping data, use single thread only! 
-  * The weekends are used for observing!
