Hi
I have Truenas Core installed on both servers main and backup.
For whatever reason, I turned off the backup server for the past year or so.
I tried to continue the replication process (maybe started a new one) and I an error.
Looks like it has to do with the fact that there's no snapshot/replication at the moment on the backup that matches the main server.
What is the best approach at this point? Start fresh? Chatgpt proposed I send a snapshot to the backup?
To consider main is 4.68T and backup is 3.07T.
Is there any major pressure on the high reads on the main server disks if theres a lot of data like 1.5 -> 5T (considering to start fresh too)
The error I am getting:
These are the snapshots on the main truenas (relevant to the dataset that I care about: EmaStorage):
On the Backup Truenas we have this:
* there's some other .system/samba on both (not sure if they are relevant?). Including some ex:
