I know everyone is busy but I would really appreciate any assistance that can be offered.
In short, I upgraded from version 8.0.20 to version 8.0.22, I had a nightly backup script and the night after the backup, my primary node crashed during the backup. I didn't notice that and the next night the secondary node crashed, putting my cluster out of service.
At first, I didn't realize that the primary node had crashed a day earlier, so I started that one first. It started, but was missing a day's worth of data The secondary node would crash every time I tried to start it. I finally started it with "--initial" and it started.
However, now the secondary node has much less data than the primary node. I am concerned that if I have to stop the primary node, my application will not have the full data available to it. Can anyone please let me know what I should do in this situation?
Thanks much!
