6/17/2008 07:56 PDT - The first step of disk cleanup has just started. The cleanup consists of three parts:
- Remove the /output and /data task subdirectories in NFS (if they exist) - note that configs are retained
- produce a list of xroot directories to delete - to be forwarded to Wilko for direct removal
- produce a list of dataCatalog directories to remove - to be forwarded to Dan for bulk task removal and dataset unregistration
The expectation is that this initial list of 141 tasks will free up ~14 TB of space in xroot and a lesser amount in NFS.
6/13/2008 - Charlotte and I (Tom) are about ready to push the button on the first phase of disk cleanup - those Monte Carlo task with directories in Xroot. A cleanup plan for xroot was circulated on 25 April 2008 (attached). Items marked "A" will be kept fully, while those marked "M" will have only merit files kept; all others will be removed entirely. After a bit more scriptage debugging we hope to begin this cleanup next Monday (16 June).
The second phase concerns MC tasks whose ROOT files were stored in /nfs. The cleanup list was distributed 10 June 2008 (attached). Additional markings explicitly indicate which tasks will be removed completely. A legend for other categories appears on the document. Work on that will hopefully begin next week.
