Warning.png WARNING
This is recommended for advanced users only, please proceed with caution.



The following guidance is provided to assist users with setting up Greyhole in Amahi 7. This has been tested with no issues. Please note this is ONLY a work around until Greyhole is integrated into the Amahi 7 dashboard.

NOTE: There is no guarantee this will work for you or not cause problems with your Amahi 7 install. Please proceed with caution as carelessness could cause data loss.

As root user, perform the following steps:

yum -y install hda-greyhole
  • Set up a mysql database and user to access it:
hda-create-db-and-user greyhole
  • Load the database schema:
mysql -u greyhole -pgreyhole  greyhole < /usr/share/greyhole/schema-mysql.sql

Initialize the basic settings for Greyhole, configure /etc/greyhole.conf:

  • Change db_user and db_password to greyhole.
  • Add a line for each drive (go here for adding new hard drives) in the storage pool at the end of the file. The example below is for two drives:
storage_pool_drive = /var/hda/files/drives/drive2/gh, min_free: 10gb
storage_pool_drive = /var/hda/files/drives/drive3/gh, min_free: 10gb
  • Now configure the number of copies per share. The example below sets the shares as follows:
    • Books for max copies (which is 1 for 2 drives)
    • Pictures for 1 copy (which is the same as max)
    • Movies for no copies
num_copies[Books] = 999
num_copies[Pictures] = 2
num_copies[Movies] = 1

NOTE: For a system with 2 Greyhole drives, 1 copy is the max. The first Greyhole drive holds the master copy and the second a copy. The share will contain a symbolic link to the master.

  • In the Dashboard, Shares tab add the following to Extra Parameters for each share you will be configuring to use Greyhole:
dfree command = /usr/bin/greyhole-dfree
vfs objects = greyhole
  • Finally, enable greyhole permanently and start the service:
systemctl enable hda-greyhole.service
systemctl start hda-greyhole.service
  • You can monitor activity by watching /var/log/greyhole.log file:
tail -f /var/log/greyhole.log
