Technical Bulletin #498: CZ /nfs/tmp File System Changes

Published on: 
March 17, 2015

Livermore Computing (LC) is pleased to announce the deployment of a new 200-TB /nfs/tmp file system on the Collaboration Zone (CZ). The /nfs/tmp file system provides temporary file space on LC production machines.

The following outlines the changes to the naming conventions during the deployment period. Please note that four weeks after deploying the new /nfs/tmp2 file system, LC will retire the existing /nfs/tmp2 file system on the CZ.

Because these are very large file systems that are primarily designated for temporary files, LC cannot copy all the data from the old file system to the new. Users need to copy what they deem important from the old file system to the new file system. CZ users should migrate their needed data to the new file system well before April 15. The data on the old file system will be irretrievably lost on that date. Please use oslic on the CZ for data transfers.

There is a 2-TB usage limit per user in the /nfs/tmp2 file systems, and as with the other temporary file systems, the data will not be backed up and will be purged on an as-needed basis when the file system exceeds 80% utilization.
