[CalendarServer-users] Help! CalendarServer was disconnected from OpenDirectory for days, and now everything is gone!?

[Sean McBride]

Hi all,

I'm running CalendarServer on macOS 10.13.6 with Server.app 5.6.3 and it's been basically set-and-forget.  But now I have a big problem.

I updated a network switch's firmware, which broke the connection from my Calendar server to my (separate) Open Directory server.  For whatever reason, the connection didn't auto-reestablish.  This went unnoticed for days during the holidays.

Back in the office today, no one could authenticate.  Magic reboot didn't help.  I had to go to Sys Prefs > Users&Groups > Login Options and un-join and re-join to the OD server.  Now I can authenticate to the calendar server, but everything seems to be gone!  Looking in the logs, I see things like:

2019-12-27T18:48:28-0500 [caldav-2]  [calendarserver.tools.purge#warn] Principal XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX is no longer in the directory; scheduling clean-up at 2020-01-03 23:48:28.984229

2020-01-03T18:48:29-0500 [caldav-1]  [calendarserver.tools.purge#warn] Cleaning up future events for principal XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX since they are no longer in directory

So has it indeed "helpfully" deleted everything for me? :(

I do have backups.  Is there a single database file I could restore?  Where is it?

Thanks for any help!!!
