Review last meeting's Action Items

linux.cscf.uwaterloo.ca

• Still blocked on comprehensive review of authentication/authorization configuration, work stalled - need to schedule in person meetings
  • Blocked on staff/manager availability

DFSc Performance

• Snapshots blocked on cleanup of old homedirs
  • Homedirs have been moved to a central directory (2 weeks ago), so far no complaints. Will delete after exams.
  • Need clarification on whether or not grace period is built into Account Expiration date - this includes 175 days after sponsorship/enrolment date * management needs to decide if we can increase the 175 day grace period to somewhere closer to 300(?) include double co-op terms
  • Should also email users who will have their homedirs deleted - Nick
    • RT: 1318097
  • Need to delete all old snapshots due to fossilized bad file ownership.
• Need to send message to users (login message (only applies to login shell), other?) when snapshots are re-enabled, links to appropriate end user documentation - Anthony
  • Will leverage MOTD to point to other more comprehensive documentation
  • Engage management on documentation location (Anthony)
    • Nick Lee maintains a useful page on www.cs.uwaterloo.ca about the general use TEACHING environment, collocating documentation there is an option. RT: 1318489
• Quotas set for most accounts, list of quota violators provided for Nick, see RT: 1317978

Endpoint Protection

• IST wants to deploy SentinelOne end point security agents on all devices
• Planning test deployment to linux.student.cs (on a single node) in passive (watch and complain) mode for fall term,

Power/Cooling outtages

• Rescheduled - According to MFCF contractor is paying for generator power

New Business

UID/GID re-use

• Currently causes problems with old homedirs winding up owned by new users, see RT: 1304698 and RT: 1319439
• Could fix, or we could just stop re-using UIDs/GIDs... Do we have any systems that don't support 32 bit UIDs/GIDs?

Bulk storage

• "new" bulk storage server (storage-202.cs.private.uwaterloo.ca).
• Ideal for workloads with relaxed performance and availability needs, i.e. database backups.
