EDIT GREYHOLE.CONF vi /etc/greyhole.conf'''SOLUTION:'''
Make sure both, user and pass are "greyhole"Refer to [https://forums.amahi.org/viewtopic.Example: db_user php?f= greyhole db_pass 16&t= greyhole db_name = greyhole5248 this] Amahi Forums article.
Edit the number of copies per share to have in the storage pool.
Example:
num_copies[Bkups] = max
num_copies[Books] = 2
num_copies[Docs] = max
num_copies[Movies] = 2
num_copies[Music] = 2
num_copies[Media] = max
num_copies[Public] = 2
num_copies[Work] = max
 
Add your drives to the storage pool:
Example:
storage_pool_drive = /var/hda/files/drives/drive1/gh, min_free: 10gb
storage_pool_drive = /var/hda/files/drives/drive2/gh, min_free: 10gb
storage_pool_drive = /var/hda/files/drives/drive3/gh, min_free: 10gb
storage_pool_drive = /var/hda/files/drives/drive4/gh, min_free: 10gb
 
In the Amahi Dashboard, Shares tab add these command lines into the Extra Parameters for each
share being used with Greyhole:
(this command lines can be double checked on the smb.conf file)
 
dfree command = /usr/bin/greyhole-dfree
vfs objects = greyhole
 
Enable and Restart Greyhole and Samba:
systemctl enable amahi-greyhole.service
service smb restart
service amahi-greyhole restart
 
MONITOR OUTPUT ON GREYHOLE.LOG FOR STATUS AND POSSIBLE ERRORS
 
tail -f /var/log/greyhole.log
 
-----------------------------------------------------------------------------------------------
PROBLEM 1
 
ERROR:
no metadata files could be created
 
NOTES:
While adding a file to one of the shares, greyhole.log gave me an error about metadata files
not being able to be created.
 
CHECK:
greyhole -s
If drives show up as offline it means that the gh directory wasn't created on the drives.
 
SOLUTION:
https://forums.amahi.org/viewtopic.php?f=16&t=5248
Execute the following command for all drives in the storage pool, then restart the service and
check for drives status again, they should show up as online.
mkdir -p /var/hda/files/drives/drive1/gh
systemctl restart amahi-greyhole.service
greyhole -s
mkdir -p /var/hda/files/drives/drive1/gh===Problem 2=== systemctl restart amahi-'''ERROR:'''Mismatched share names on greyhole.service greyhole -sconf and smb.conf
-----------------------------------------------------------------------------------------------
PROBLEM 2
 
ERROR:
Mismatched share names on greyhole.conf and sms.conf
 
NOTES:
Noticed the error on greyhole.log while greyhole tried to create copies of files added to the
storage pool.
'''SOLUTION:Make sure when you set the number of copies on the "vi /etc/greyhole.conf" command, that all[xShare] names on the file match exactly the share names on the Amahi Dashboard, delete any shares that do not show up on the Dashboard.'''
-----------------------------------------------------------------------------------------------PROBLEM 3Make sure when you set the number of copies on the "vi /etc/greyhole.conf" command, that all [xShare] names on the file match exactly the share names on the Amahi Dashboard, delete any shares that do not show up on the Dashboard.
===Problem 3==='''ERROR:'''
LZ for one of the shares filed up and Greyhole stopped making copies of the files.
NOTES:
Added about 200GB of data to one of the shares, the LZ for it was located on the "/" partition
on the 120GB SSD (sde) used for the OS. Moved all share's LZs to the 4th 3TB storage drive (sdd). SOLUTION:(This step is optional) First, you might want to wait until the Greyhole is done working on thelatest changes. You can check that by looking at /var/log/greyhole.log: look for Sleeping... log lines. Doing so will speed up the whole process of moving your LZ. Stop the Samba service. Turn off the Watchdog option in the Setup > Advanced > Servers page, and then stop the service.

Edit * Stop the share path on Greyhole service. Turn off the Amahi DashboardWatchdog option in the Setup > Advanced > Servers page, Shares tab to reflect and then stop the new pathservice.
Repeat * Move the last two steps for all the shares youLZ from it'd like s old path to relocatethe new path. mv /var/hda/files/xshare /var/hda/files/drives/drive4/xshare
Restart * Edit the Greyhole service. Turn back share path on the Watchdog option in Amahi Dashboard, Shares tab to reflect the Setup > Advanced > Servers page, and then start new path. Repeat the last two steps for all the serviceshares you'd like to relocate.
