IPBrick Disk migration

This guide is to assist the IT IPBRICK administrator in the process of migrating a running IPBRICK installation from:

  • scenario 1 : one disk to another disk on the same server machine
  • scenario 2 : one disk to another disk on a different server machine


On the original server machine

On the original installation, apply configuration and save the configurations file to your Desktop.

Just stop the the services you use. 

/etc/init.d/asterisk stop
/etc/init.d/apache2 stop
/etc/init.d/ejabberd stop
/etc/init.d/qmail stop
...


Execute this command to backup all the data bases. 

php5 /opt/system/backupSYS/backup_DBs.php

Scenario 1 - only one server machine

Procedure:

  • shutdown the server machine
  • remove/detach the original (old) disk from the server
  • install/attach the replacement (new) disk
  • install the IPBRICK.IC operating system (please refer to IPBRICK.IC installation manual)
    • perform the first boot, proceed with initial setup (FQDN, IP)
    • after finishing installation and initial configuration proceed to the next step
  • with the server power on, connect the old (original) disk using a USB connector
    • now at the command line you can check for the disks 
fdisk -l
  • confirm that you have 2 (two) disks: sda (new internal disk) and sdb (old disk connected via usb)
    • you shoudl be able to identify the partition tables
  • create two temporary folders to map/mount the work areas from the old disk 
mkdir /old_home1
mkdir /old_home2
ls /old_home* -al
  • Then we need to mount the partitions we need to copy. 
mount /dev/sdb7 /old_home1
mount /dev/sdb8 /old_home2
  • Now lets start the rsync 
rsync -aAuv /old_home1 /home1 > /tmp/rsync_home1.log 2> /tmp/rsync_home1.err &
rsync -aAuv /old_home2 /home2 > /tmp/rsync_home2.log 2> /tmp/rsync_home2.err &
  • You can see the logs in these files (log is normal output, err is for status warning) 
tail /tmp/rsync_home1.log
tail /tmp/rsync_home1.err
tail /tmp/rsync_home2.log
tail /tmp/rsync_home2.err
  • Wen the rsync is finish access to web interface and then insert and replace the configuration that you save on your desktop.
  • After replacing, go to Advanced configuration -> disaster recovery -> aplication -> data bases -> and replace the last one.
  • Wen this Finnish test the services you have on IPBrick.


Scenario 2 - rsync using 2 IPBrick==

Install the IPBrick on the new machine or on the new disk.

Make the rsync command to copy all the data to the new disk, Some examples of rsync


EX: IPBrick1 New (192.168.69.199) and IPBrick2 OLD (192.168.69.200)

On machine IPBrick2 open ssh to root 

cat /etc/ssh/sshusers-allowed
operator
root

insert the line root on the file.

Now lets start the rsync on IPBrick1 

rsync -avz --rsh="ssh -l root" 192.168.69.200:/home1 /home1 > rsync_home1.log 2> rsync_home1.err
rsync -avz --rsh="ssh -l root" 192.168.69.200:/home2 /home2 > rsync_home2.log 2> rsync_home2.err
  • the route password will be prompt to insert.

You can see the logs in this file -> rsync_home1.log Or the errors in this file -> rsync_home1.err

Wen the rsync is finish access to web interface and then insert and replace the configuration that you save on your desktop.

After replacing, go to Advanced configuration -> disaster recovery -> aplication -> data bases -> and replace the last one.


Wen this Finnish test the services you have on IPBrick.
