Review last meeting's Action Items

• Homedirectory quotas (a2brenna) - RTs: 1112506,1288354,1298614 et al
  • 100 GB quotas in staged roll out, plan detailed in tickets above
    • Email sent, see RT: 1288354
      • Will need direction from Management / The School on what to do about URAs - need more clarification from Director
      • Do we track URA requests? (Clayton? )
      • Nick to send second reminder in Oct
  • Tooling to implement quotas
    • Calculate current quotas from sponsorship information, see RT1298614 (Clayton)
    • Update quota xattr on homedirectories (Nathan)
    • Build a data file that outputs the user and quota information. Specifics to be worked out between Clayton and Nathan.
  • See https://rt.uwaterloo.ca/Ticket/Display.html?id=1298614#txn-32655210
    • There appears to be 3 (teaching, non-course-account) users with sponsored quota in excess of 100GB
    • Should be safe to apply a 100GB quota to all other TEACHING user accounts currently using less than 100GB
    • Maybe re-run that query as sponsorships can change
• CS Mailservers are going away
  • No update - Anthony to send instructions to CSCF staff members on updates needed to server
• Ongoing problems with Inventory and IPAM are hobbling Infrastructure operations - RT1285291
  • Am scheduling some time to talk with Inventory team about the following (a2brenna)
    • Inventory is unaware of this IP / domain limitations in IPAM as well as DHCP and MAC address requirements
    • Some CSCF do not have access to create manual DNS entries (Devon, Lori, Guoxiang, Todd have access. Dave?)
    • Inventory bug: Changing room field on a record with IPAM DNS & DHCP causes DHCP to break
    • Anthony to reach out to IST for clarification regarding is this a policy vs technological limitation.
    • Invalid records were imported from Infoblox that work until they are edited
• MySQL reboot completed
  • • reboots need to be scheduled before term starts, start process at the finish of exams
• Scheduling Nextcloud DB migration ~21st (Nathan, Fraser)
• Old windows.cscf still running as maculata.cs.uwaterloo.ca (Clayton)
• NFS ganesha server needed rebooting on Monday
  • • need to add tests/checks for mounts
