Wiping of /scratch and Systems and Services Unavailable on Wednesday, February 17

by Computer Science Club

TL;DR /scratch will be wiped and systems will be unavailable on Wednesday, February 17. Hello everyone, Below are some important (and non-important) updates from the Computer Science Club Systems Committee. SYSTEM MAINTENANCE (AND OUTAGES) ON WEDNESDAY, FEBRUARY 17 On Wednesday, February 17, system maintenance will be occurring from 11:00am until 5:00pm. IMPORTANT NOTICES: 1. All running jobs will be terminated as all systems will be rebooted at the start of the maintenance period 2. A failing drive in the /scratch array will be replaced. As /scratch is currently configured as a RAID0 all data will be erased. This is a reminder that /scratch is volatile storage and data may disappear at any time. If there is anything in /scratch for which you do not have a copy of (or cannot re-create), please ensure you have a copy of it prior to the start of the maintenance period. IMPACTS - All services provided by the CSC (web hosting, mail, etc.) will be unavailable during the maintenance period We apologize in advance for any inconvenience this may cause. INFORMATIONAL UPDATES 1. Mirror Upgrades The Computer Science Club Mirror is now running on potassium-benzoate, our new server which was purchased with funding from the Mathematics Endowment Fund (MEF). We have also enhanced our mirror's network connectivity, adding IPv6 and 10Gbps. Running our mirror is made possible with assistance from: - The Mathematics Endowment Fund (MEF) - The Mathematics Society (MathSoc) - Dave Gawley and the Computer Science Computing Facility (CSCF) - Information Systems Technology (IST) 2. IPv6 The CSC network now has IPv6 addresses and all of our services have been configured to accept connections over IPv6. For those hosting their website via personal domain names and wanting IPv6 connectivity: If hosted with a CNAME, no action is required. If not hosted with a CNAME, you can add the following AAAA record "2620:101:f000:4901:c5c::caff:e12e" 3. Firewall The campus firewall will soon be enabled on our network. After this date, only select traffic will be permitted from off-campus to our machines (on-campus and VPN traffic will not be affected). All general use servers will have SSH, Mosh and ports 28000-28500 open on the campus firewall. If you have any questions, concerns or comments, please email the Systems Committee at syscom(a)csclub.uwaterloo.ca. Thanks, Zachary Seguin Systems Administrator | Computer Science Club University of Waterloo syscom(a)csclub.uwaterloo.ca
