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 shared by all accounts.
All accounts have access to the /raid1 directory which is a 3.3TB raid 5-0 array on the file server.
The nodes cmsroc1-cmsroc10 have a 65GB /scratch1 directory and a 250GB /scratch2 directory for use by all accounts.
The nodes cmsroc11-cmsroc12 have a 800GB /data directory for use by the cmsroc_hcal account.
Each account has been allocated 2GB in the /uscms/home directory and 10GB in the /uscms_data/d1 directories.
The /scratch1 and /scratch2 directories are not backed up.
The /data directory is not backed up. The /uscms/home directories are backed up nightly by the Tier 1 team.
The /stage1 directory is backed up nightly to the raid5 array.
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.
