We have decided to move the mail server off the CP server and onto a redudant new server that would exclusively dedicated to mail. This has been done so as in the recent months, with the latest version of Hsphere, we have encountered one major as well as some minor issues with qmail
The shift is scheduled to take place on Jan 6th, 2AM EST. No disruption of services will occur, the change would be 100% transparent.
The shift, along with automated fail-over for our mail servers that we’d introduce on Jan 6th will help in ensuring 100% uptime on our mail servers
We have shifted the scheduled shift one day back to Jan 5, 2AM EST
We expect NO DOWNTIME during this entire shift. The following would be performed during the shift (I have received requests to explain how it’d be carried out)
New P4 2.8GHZ HT server with 200GBx2 RAID1 SATA and 2GB of RAM setup. QMAIL installed
RSYNC would be setup to copy data from cp server to the new mail server.
After a period of time, we’d setup QMAIL to redirect all POP3/SMTP traffic to the new mail server while we test out everything and ensure all systems are performing at 100%
Once things have been verified, we will be unbinding the mail server IP from the cp server and binding it to the new mail server. Shift would be complete
Absolutely NO change in mail server IP or DNS propogation is involved
Once the shift is completed, we’d implement fail-over for our mail server to ensure that in the future if our mail server ever goes down, our backup mail server takes over
We have disabled singups on the mailserver, as the new accounts may get lost in the migration process. It will be enabled in around 3 hours.
Due to this any new account signups/domain creation may see an error like this:
"
Failed to add new resource.
There is no host available for signup, group 3
"
Kindly defer this until the singups are enabled again.
