Disk Write Privileges

To obtain disk space allocations on the D0 Unix machines you need to go through a few steps.

1. To find out what disks are available and their assignments:
   • Login to d0mino (RunII) or d0cha(RunI). You must login to each machine because the disks aren't mounted unless they are being accessed. You have to know their names before you can access them.
   • For project disks (cross-mounted as /prj_root/*):
     On each machine: ls /projects/*
     The listing will show several files. The important ones are the directories and files with names of the form:
     001-<grp_name>-<kB allocated>-<backup status>.< manager>
     where <grp_name> is a project name. <manager> is the username of the disk's manager.
   • For University disks (cross-mounted as /tmp_root/*):
     On each machine: ls /usrdisks/* (I know, bad name)
     You'll see the same format 001* files, where <grp_name> is a university's Unix group name.

   NOTE: Do not use /projects/<num> or /usrdisks/<dir> in scripts. It is /prj_root/<num> and /tmp_root/<num> that are invariant between machines.

2. Contact the person listed as the <manager> in the 001* filename to be given write privileges.

3. To obtain additional space for an existing project contact the head of the Computer Policy Board's (CPB) subgroup of which you are a part or Darien Wood for RunI.

NOTE: Projects will be reviewed yearly for their current appropriateness by the CPB.
