Disk Write Privileges

To obtain disk space allocations on the D0 Unix machines you need to go through a few steps. Note, this page isn't relevant for ClueD0.

1. To find out what disks are available and their assignments:
   • Login to d0mino. You have to know the disk names before you can access them.
   • For project disks (cross-mounted as /prj_root/*):
     Enter: 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/*):
     Enter: ls /usrdisks/*
     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, create a new project, or find out which group you belong to, contact Amber Boehnlein.
