If you want to use email (e.g., you want to cut-and-paste an error message and send it to me), as a backup you can use Columbia LionMail![]() wgs1 . |

Mail Server Upgrade 15-Aug-2016I propose upgrading the Nevis mail server on Monday, 15-Aug-2016, at 12:45PM Eastern Time. If all goes smoothly, the mail server will be down for no more than 15 minutes, then everything will go forward as before. | ||||||||

When | ||||||||
Line: 14 to 14 | ||||||||
Go to lunch at 12:45PM. When you come back to your desk, the switch will hopefully be over. | ||||||||

No. Your mail files are not kept on the mail server virtual machine. They're kept on a different machine: see the pages on mail-related files and the list of machines; the directory /a/mail is on the central administrative server hypatia , not in the mail server virtual machine franklin . |

If there's a problem with the upgrade, we all want to know about it right away. If I wait until the evening or just before the weekend, then you might be frantically trying to reach me in the middle of the night or when I'm away. Go to lunch at 12:45PM.

WhatWhat exactly are you doing? I'm upgrading the mail server to use CentOS 7![]() ![]() ![]() 7 to the end of the server's name; e.g., mail.nevis.columbia.edu becomes mail7.nevis.columbia.edu , smtp.nevis.columbia.edu becomes smtp7.nevis.columbia.edu , etc. Don't forget to switch back before the date of the change! I've already tested the new server, but additional eyes can never hurt.
WhereWill I lose all my mail files? No. Your mail files are not kept on the mail server virtual machine. They're kept on a different machine: see the pages on mail-related files and the list of machines; the directory/a/mail is on the central administrative server hypatia , not in the mail server virtual machine franklin .
It's vaguely possible that your mail reader may not display your mail temporarily because it loses track of your files (though this has not happened in any of my tests). Just restart your mail reader and everything should be fine.
If your mail files don't reappear, contact me.
