Mail Problem
The Big Switch
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.
