Editing Infrastructure Machines (section)

=== Moving from one server to another ===

Here are the steps you would take to move settings and data from one server to a new backup server:

* rsync over all /data/customers (we do this cause if we didn't use *-file it would copy over the files AND the data in the mountpoint)
 rsync -av --progress --ignore-times *-file root@10.1.2.33:/data/customers/
after umounting all the customers, copy over the (empty) directories separately:
 for f in `find .  -type d`; do rsync -av $f root@69.55.229.25:/data/customers; done

* copy mount script
 [root@backup3 /data/customers]# scp /etc/nfs_backup_mounts.sh root@69.55.229.25:/etc/nfs_backup_mounts.sh

* copy rc.local
 [root@backup3 /data/customers]# scp /etc/rc.local root@69.55.229.25:/etc/rc.local

* copy /etc/exports
 [root@backup3 /data/customers]# scp /etc/exports root@69.55.229.25:/etc/exports

* edit /etc/hostname on both machines (set current to oldbackup3)

* edit /etc/network/interfaces (swap IPs). 

* stop mounts from mounting on old and new servers so it doesnt start with reboot right away:
 chmod 000 /etc/nfs_backup_mounts.sh

* reboot both servers @ same time

* check everything out

* run /etc/nfs_backup_mounts.sh on new server

* if switch port changed update mrtg to reflect correct port pub nic is on (on p20):
 vi /usr/local/www/mgmt/mrtg/mrtg1.cfg
