Mobilizon Migration

Mobilizon

Resolved after 2h 40m of downtime. June 14, 2021 at 2:40 AM UTC

I am going to begin the process of migrating Mobilizon to the new server at 00:00 UTC (20:00 EDT). I don’t know for sure how long the process will take but expect at least 2 hours of downtime. In general, migrations look like this:

  1. Upgrade the application on the old server
  2. Stop all related processes
  3. Back everything up
  4. Copy backups to the new server
  5. Import databases
  6. Ensure file permissions are correct
  7. Start processes
  8. Implement automated backups with tarsnap

Step 4 will take the longest by far; the limited bandwidth of the old system results in terribly slow network operations. Because of the database size, the limited bandwidth caused Pleroma’s migration to take hours; I don’t expect Mobilizon to be quite as bad but it very well could be. (22:53 UTC — Jun 13)

Upgrades

I’m leaving processes stopped so data doesn’t change between the backup and restore points.

Migrations

Aside from some odd behaviour that may be an upstream bug(? going to test), I’m fairly certain everything is back to normal. (02:49 UTC — Jun 13)
