Chebucto Suite Workshop

Agenda

Mail Problem

A mailing list went wild on Friday and filled up the mail partition with a debug file of 300 MB.
Users' mailboxes were corrupted when attempting to write out the mailbox on exit.
A combined effort by Kassiem, Michael, David Potter and others was able to bring the problem under control, and repair the approximately 200 mailboxes affected, using at least 6 hours of volunteer time.

Several questions were raised by this incident:

How is it that several users have their mail forwarded to themselves? (It was understood that the script should prevent that from occurring.)
How can we improve communication among the various methods that problems are reported (office telephone and e-mail, helpdoc, userhelp, postmaster, ip-help, techteam?)
Consider if more items in Pine configuration should be locked in the global configuration file pine-conf-fixed.

The BIG Switch

Issues remaining before undertaking the switch

Pine testing
TQ - needs fixes and parameters, but not show stopper. Locate uses of tty names.
quotas are set
lynxexec and lynxprog links that may need updating
Lines - Kassiem will configure 6744 lines to halifax for immediate testing. 11 lines will be configured to chebucto to boost access.
networking - Kassiem will find procedure for setting up virtual interfaces from DT, notify NOC as needed
news - Ed and others will test tin on halifax.

The actual switch will be performed Saturday, if satisfactory testing results are achieved between Wednesday and Friday.
Decision time is Friday afternoon. If the decision is made to go, we will retain old chebucto in condition to allow immediate reversion should it become needed over the next few days, and of course, to allow backing out of the transfer if necessary.
