LDAP/Kerberos upgrade Sunday 2/19

As part of our ongoing work to transition from jessie to stretch at the OCF, we will be migrating our LDAP/Kerberos server today starting around 7:20 PM.

To do this, we'll import LDAP and Kerberos data from our on-site backups to test that they still work. Although they have been tested before, it's always nice to make sure that backups actually work and include the right data. After importing these backups, a final dump and sync will be made in case any data has changed in the small amount of time that it takes to import the backup data.

All users will be unable to log in while the migration is taking place, but this should only be a very short time, as the majority of the migration will be done before the final sync is done.

Contact us if you have any questions or concerns about the upgrade!

Update 7:40: All users should be able to log in again, please let us know if you have any issues with accessing your account!

MySQL read-only Saturday 2/18

As part of our work to transition from jessie to stretch for our MySQL server, we'll be migrating user data today around 5pm.

To do this, we'll put the existing jessie server into read-only mode, then make a final import to the new stretch host. We believe this will take about an hour and don't anticipate any issues (we've already tested imports from our regular backups without problems).

Read-only mode is necessary during the import to ensure we get a consistent backup, and so that writes made during the transition are not lost.

Some sites may experience downtime while the server is in read-only mode (if they require writing to the database to show pages). Most sites will experience some level of degradation (e.g. can't log in to admin or edit posts).

Update 5:01pm: We have entered read-only mode.
Update 5:58pm: The backup has completed, we are now importing it into the new database server. Probably another 45 minutes or so.
Update 6:07pm: ETA 25 minutes.
Update 6:15pm: ETA 16 minutes
Update 6:25pm: Unfortunately we hit a snag during the import and have to start it over.
Update 6:29pm: ETA 37 minutes.
Update 6:40pm: ETA 21 minutes.
Update 6:46pm: ETA 10 minutes.
Update 6:56pm: Import has finished, we're now switching back into rw mode. This will involve a few seconds of downtime.
Update 6:59pm: MySQL is now available as usual. Total time in read-only mode was about two hours. Total downtime was less than a minute.

Daily print quota change 12/5-12/16

For all you who need to print out final papers, the OCF daily printing quota will be increased to 20 pages/day for RRR week and finals week this semester.

This is not a permanent change, nor have we decided yet whether to repeat this bump in future semesters. The semesterly quota is still 100 pages.

Changes to account policies

We've revamped our account policies, principally to be more specific on the reasons accounts can be disabled. We've also established a formal procedure for revoking the membership privileges of disruptive OCF members.

Our revised account policies are accessible at https://www.ocf.berkeley.edu/docs/services/account/account-policies/, and the banning policy is accessible at https://www.ocf.berkeley.edu/docs/membership/banning/.
