-Install the new disk in the SME Server while turned off, then boot it up.+:!: We also use this technique in virtualized server installations.  For example, if you create a VM using a single large virtual disk, you may easily get to a point where you can't snapshot it due to lack of free disk space.  Using this technique, you can temporarily disconnect the second large 'data' disk, take a snapshot, then reconnect the virtual disk when done.  Just one of the reasons why you should use (expensive) shared storage for your virtualization projects...

 +===== Installation ===== 
 + 
 +Shut down the SME Server and physically install the new disk while turned off, then boot it back up.
  
 Partition the drive with one large partition.  Use a [[computing:storage:disk_partitioning|GPT partition table]] if the drive is over 2TB. Partition the drive with one large partition.  Use a [[computing:storage:disk_partitioning|GPT partition table]] if the drive is over 2TB.

 </file> </file>

 +:!: Use EXT4 for SME Server version 9.

 + 
 +===== Final Steps ===== 
 + 
 +Once we test the new configuration, including at least one reboot, we can take steps to recover the disk space occupied by the original /home data. 
 + 
 +:!: If this is a clean SME Server install and you realize there is little space to be gained, stop right now.

 +Carefully:

 +<file> 
 +df -h                                 # just to check the current disk utilization 
 +umount /home 
 +mount                                 # just to make sure the new partition is no longer mounted 
 +du -sh /home/*                        # just to see what we are about to delete 
 +rm -rf /home/* 
 +mount -a 
 +df -h                                 # compare the results with the first command
