The default setup in Fedora is to use Logical Volume Management ([https://www.amahi.org/faq/does-amahi-support-lvm LVM]) which creates added complexity for inexperienced users.  There is a lot of drive space dedicated to a /home partition.  The Amahi team recommends removing the /home partition for best results.

Warning.png WARNING
Recommend you disable/unplug ALL hard disks you do not want to put the system on to make it easier to partition. Data loss can result if you accidentally get confused about what disks are which or you make an error.


The Amahi team makes the following recommendations when partitioning drives in Amahi 7 or greater:

  • Skip using Logical Volume Management (LVM), which creates added complexity for inexperienced users, in particular if there are disk failures.
  • Do not make a separate /home partition. Amahi does not recommend use of /home for storage for users
  • Allocate the majority of hard drive space in the / (root) partition.
  • Do not add extra drives while installing. recommend you do that later after the system is up and running successfully using adding a second hard drive to your HDA as a guide.
  • The majority of space, to be used by file shares is set up to be at /var/hda/files, which typically resides in the root partition.
  • If you plan to use the Greyhole drive pooling technology, keep in mind that by default the Greyhole "Landing Zone" will be located in the root partition. This needs to have enough space to accommodate the single largest transaction that you plan or foresee you will make.

How to Partition

At the partitioning point of the Fedora installer, you do this:

  • Select INSTALLATION DESTINATION under STORAGE section.
  • Verify the correct drive is selected, then choose Done.
  • Ensure Partition scheme reflects Standard Partition.
  • Choose I want to review/modify my disk partitions before continuing and select Continue.
  • When prompted with INSTALLATION OPTIONS, select Custom partitioning.
  • Choose each partition and select the minus (-) to remove them individually until all the partitions have been removed.
  1. If prompted Are you sure you want to delete all the data on..., choose Delete it
  2. Ensure Delete all other filesystems in the Unknown root as well is selected.
  • You should now see the message You haven't created any mount points for your installation yet.
  • First we need to make the Swap. Click on the plus (+) and a window will appear:
  1. Choose Mount Point of Swap.
  2. Enter Desired Capacity based on the chart below.
  3. Select Add mount point.
NOTE: The recommended size of a swap partition depending on the amount of RAM in your system.
System RAM Recommended swap space
< 2GB 2 times the amount of RAM
> 2GB – 8GB Equal to the amount of RAM
> 8GB – 64GB 0.5 times the amount of RAM
> 64GB 4GB of swap space
  • Next is /boot. Click on the plus (+) and a window will appear:
  1. Choose Mount Point of /boot.
  2. Enter Desired Capacity of 500MB.
  3. Select Add mount point.
  • The last one is the / (root). Click on the plus (+) and a window will appear:
  1. Choose Mount Point of /.
  2. Enter Desired Capacity of the amount of remaining disk space (this is displayed at the bottom of the installer window)
  3. Select Add mount point.
  • Review the partition scheme and if it looks ok, choose Done and select Accept changes.


You can now continue with the install as normal.

Example

For a system with 1GB RAM and 10GB hard drive, the following settings would apply for Desired capacity:

  • Swap = 2GB
  • /boot = 500MB
  • / = 7.73GB
