9.2 (U) Server Recovery Procedure
(U) If a CB Master server has failed, and has been repaired, follow these instructions to
bring it back online.
(U) Run all commands as root unless cbuser is specified.
1. BEFORE connecting the Old Master back to the Thunderdome network, obtain a
“root” console (see section 5.4) to the server and run the following:
~cbuser/bin/disable-server.sh
2. Connect the server to the Thunderdome network.
3. Any copydata, proxydata, or MissionFiles not transferred from the old master to
the new master should be synchronized. As 'cbuser' on the Old Master, run:
~cbuser/bin/sync-<New Master IP>.sh
Note: this script should run automatically once the Old Master has been up for 5
minutes.
4. Make the Old Master server a Slave. From a “root” console (see section 5.4),
obtain a terminal (ssh or DRAC) to the Current Master, and run:
cd ~cbuser/bin && ./add-cb-slave.sh
