Do not use samba-tool dbcheck --cross-ncs --fix --yes command.
You will still encouters errors.

July 27, 2026 Demote RodcServer.

A crash of the RODC server results in the loss of user UIDs and group GIDs.
Rebuilding the new RODC server will create new user UIDs and group GIDs.
Share permissions will be assigned to other users or groups.

Unless you previously backed up /var/lib/samba.
cd /var/lib
tar -cvf /home/teacher/samba.tar samba

But I haven't checked.

I recommend performing a full backup of the RODC server.

The command to remove an RODC.
Please note: this command must be executed on the server that is to be deleted.
