Accounts and Directories

Each of these Linux PC's have local accounts  for use in ROC operations. The account home directories are stored on /stage1 directory which has 70GB for all accounts. All accounts have access to the /raid1 directory which is a 3.3TB raid 5 array on the file server. Each PC has a 65GB /scratch1 directory and a 250GB /scratch2 directory for use by all accounts. Each account has been allocated 2GB in the /uscms/home directory and  10GB in the /uscms_data/d1 directories. The /scratch1 and /scratch2 partitions are not backed up. The /uscms/home directories are backed up nightly by the Tier 1 team. The /stage1 directory is copied to the raid5 array nightly for backup. The UAF accounts are also added to these PC's to allow local and remote login. The  ROC accounts are listed in the table below.
