DokuWiki

• Implementation
• add usrquota,grpquota options to fstab, remount
• log everybody out or reboot (quota error on boot, not initialized yet)
• quotaoff
• quotacheck -cvug /home (file system goes read only! 10TB of whcih 6TB used, took 3 hours)
• set default user quota and propagate to all users
• set custom quotas for other users
• wrap adduser
• quotaon

• Array
• 48 TB minus 4 global spares
• after formatting 36 TB available
• /home 10, /snapshots 10, /sanscratch 5 after that leaves 11 TB
• snapshots holds base plus deltas hence needs to be somewhere between 1-2x base
• so if we wanted to increase home, we could not use sanscratch (is anybody using it?)
• if we do not backup, then … questions for later

• Links
• Quota mini HOWTO
• Admin: Quotas
• useradd wrap and default quotas
