Adding quotas

Published by admin-joel on 2006-04-13

OUT OF DATE as of 2008-11-01.

Steps: (from http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/admin-primer/s1-storage-quotas.html)

  1. Modified /etc/fstab entry for /home and rebooted:
    /dev/md0 /home ext3 defaults,usrquota,grpquota 1 2
  2. Run:
    quotacheck -avug

    If that fails, can try:
    quotacheck -avugcm

  3. Added the quotacheck command to /etc/cron.weekly with the script:#!/bin/bash
    # Update the database that keeps track of quotas
    # Created by Mark Knight (4.13.06)
    # Modified by Mark Knight (5.06.06)
    quotaoff -a
    quotacheck -agum
    quotaon -a

    exit 0

  4. Set user quotas:
    1. Command:
      edquota knightm
    2. Disk quotas for user knightm (uid 500):
      Filesystem blocks soft hard inodes soft hard
      /dev/md0 1420 512000 1000000 126 0 0
      This sets a soft limit of 512 MB on the user “knightm,” with a hard limit of 1 gig.
  5. Check limits on quotas with
    repquota /home

2/4/2009: This is old stuff (old server, old setup). Move to trash? –James Fuller

The plan for making Algol the Arcy replacement:

  1. Register system
  2. Go through current Arcy accounts & purge inactive or old
  3. Get LDAP set up to authenticate off of ITS servers
    1. Set up accounts locally for all users on current Arcturus
  4. Set up email list on lists.carleton.edu
  5. Establish quotas for users (200 megs?)
  6. Install software
    1. IDL – new version
    2. SFTP server
    3. Mathematica
  7. Figure out directory structure (how do users share data?)
  8. Mount network drive script (HOME, COLLAB, COURSES)
  9. Set up AMANDA with SDLT tape drive ::frown!::

Note: we are NOT setting up the mail server.
