This tutorial is now available as the Amahi Greyhole Mount Shares Locally application.
Purpose
Mounting your Samba shares locally within your HDA is useful when you want a process running within your HDA to write data in a way that ends up in a Greyhole-managed share.
The reason is that Greyhole data should 'only be modified through shares, not directly onto the local file system, so mounting those shares locally is an easy way to work with Greyhole data safely.
For example, if an app like a downloader gets files from the internet and you want those files to be in a Greyhole-managed share, it has to place them into the share, not directly into the operating system, or Greyhole otherwise cannot handle them.
Contents
Download and Setup
- As root (or precede commands with
sudo
), install the mount_shares_locally initd script:
Amahi 10 or greater (Fedora)
dnf install cifs-utils cp /usr/share/hda-ctl/mount_shares_locally /etc/init.d chmod +x /etc/init.d/mount_shares_locally chkconfig --add mount_shares_locally
Amahi 7/8/9 (Fedora)
yum install cifs-utils curl -o /etc/init.d/mount_shares_locally http://dl.amahi.org/mount_shares_locally.fedora chmod +x /etc/init.d/mount_shares_locally chkconfig --add mount_shares_locally
- NOTE:
yum
(deprecated) has been replaced withdnf
as the package manager for Fedora 23 or greater.
- NOTE:
Amahi 6 (Ubuntu 12.04)
sudo apt-get install cifs-utils curl sudo curl -o /etc/init.d/mount_shares_locally http://dl.amahi.org/mount_shares_locally.ubuntu sudo chmod +x /etc/init.d/mount_shares_locally sudo update-rc.d mount_shares_locally defaults
Configuration
- As root, edit /etc/init.d/mount_shares_locally
- Replace "***set this string to your username!***" (line 12) with your username. For example:
username="amahi";
- The script may require the MariaDB root password be changed:
- Please see Database Root Password for the appropriate login password (change for Amahi 10 ONLY).
- Also if you changed the MariaDB root password on your own.
Change hda (line 25) to the appropriate password if needed:
mysql -u root -p hda -e "select name from shares" hda_production | grep -v "^name$" | xargs -d "\n" mkdir -p
- Create the /home/your_username/.smb_credentials file. This is a simple text file (use your favorite text editor).
vi /home/your_username/.smb_credentials
- Enter the following:
username=your_username password=your_password domain=HOME
- Verify the .smb_credentials is owned by root:root or 1stadminuser:users:
ls -al /home/your_username/.smb_credentials
- NOTE: your_username and your_password in the .smb_credentials file needs to be the original username (1st Admin User) and password you created when you installed the OS (NOT root). Also ensure the domain matches the Workgroup set for shares.
- To test your new mounts, you can execute as root user:
- Mount
systemctl daemon-reload service mount_shares_locally start
- Unmount
service mount_shares_locally stop
- NOTE: If you used /etc/rc.local and /etc/fstab to mount shares locally in the past, you can remove what you added in those files now (DO NOT remove the drive mount lines). The above initd script replaces all this.
If you added new share to Greyhole, you need to restart the script by executing as root user (or sudo):
service mount_shares_locally restart
This will unmount and remount all your shares, reflecting all the new shares you added.
Where everything is mounted
You will find the mounted shares in /mnt/samba/* and should look something like this:
drwxrwx--- 2 your_username users 0 Aug 9 23:31 Books drwxrwx--- 2 your_username users 0 Aug 9 23:31 Docs drwxrwx--- 2 your_username users 0 Mar 2 16:15 Movies drwxrwx--- 2 your_username users 0 Aug 9 23:31 Music drwxrwx--- 2 your_username users 0 Aug 9 23:31 Pictures drwxrwx--- 2 your_username users 0 Aug 9 23:31 Public drwxrwx--- 2 your_username users 0 Jul 29 02:02 TV drwxrwx--- 2 your_username users 0 Aug 9 23:31 Videos
For example, your "Pictures" share would be located at /mnt/samba/Pictures. When working with files on the HDA, access them via this share and NOT the traditional /var/hda/files/pictures location.
Uninstall
To uninstall mount_shares_locally, do the following as root:
service mount_shares_locally stop rm -rf /etc/init.d/mount_shares_locally rm -rf /home/your_username/.smb_credentials chkconfig --del mount_shares_locally rm -rf /mnt/samba/*
Now if you choose to reinstall later, your machine will be in a clean state.
Warning! |
---|
This is NOT an officially supported script for Amahi. Use at your own risk. We cannot guarantee it will work. |
Some apps used by Amahi are used to download files etc. Often we want these files to end up in our shares. Let's say that SickBeard is used to download TV episodes. You then have to configure SickBeard to place your new episode somewhere. A logical place is to save to the landing zone of your Greyhole share which could be /var/hda/files/TV. There are two downsides to this though.
- Greyhole is not notified of the fact that a file is added and only discovers it and makes it available in your share after a fsck, which could take a long time.
- Files deleted through apps in this folder don't register a delete event that Greyhole can pick up and thus only the symlink in the landing zone is removed. The actual file copies remain on disc. Similarly users running Plex Media Server for example will have issues if the clients are allowed to delete contents and the server is configured to work on the landing zone. I described this issue when packaging Plex a long time ago here.
Since Greyhole uses Samba as a layer between the user and itself we would like to keep our writes and deletes to the shares and not the actual landing zone. But since apps (most of them) run as the user apache it will not be able to access /mnt/samba, which is the default mount point if you set up mount_shares_locally. This following script retains the function of the original script but also adds a second mount point under /mnt/apache where the apache user will have read and write access. I have kept it simple and it will use the same credentials as the main mount. So only shares available to that user will be available for apache.
By doing this apache will now have a place where it is allowed to read and write files to your shares and SickBeard can thus be configured to place the new episode in /mnt/apache/TV which is then instantly picked up by Greyhole and file copies distributed to the discs in your pool as configured.
Note that this script is based of the Greyhole original one and uses /etc/samba/smb.conf as the source of your shares and does not load the shares from the database like the old HDA version of the script did. If that behaviour is desired that can be easily added by replacing the lines
testparm -s /etc/samba/smb.conf 2>/dev/null | grep "^\[" | grep -v "\[global\]" | grep -v "\[homes\]" | awk -F'[' '{print $2}' | awk -F']' '{print $1}' | xargs -d "\n" mkdir -p
with
mysql -u root -p -e "select comment from shares" hda_production | grep -v "^comment$" | xargs -d "\n" mkdir -p
WARNING: Please see Database Root Password for the appropriate login password.
Troubleshooting
MySQL Problems
Since Greyhole moved from SQL Lite to MySQL, you may hit a problem where Greyhole and the mount_shares_locally script both attempt to start before MySQL in bootup, leading to the services not starting properly. If this happens, you can try this to fix it:
ls /etc/rc.d/rc3.d/
- Look for any entries marked S-1. If there are any, they need to be removed. Run the following as root:
rm S-1*
Ensure your share file and ownership permissions are correct:
ls -al /var/hda/files
For example, the correct permissions are:
drwxr-xr-x. 10 root root 4096 Jul 29 17:02 . drwxr-xr-x. 13 root root 4096 Dec 5 2013 .. drwxrwxr-x 2 1stadmin users 4096 Dec 5 2013 books
If this is not correct, you will need to change them:
chmod -R 775 /var/hda/files/sharename chown -R 1stadminuser:users /var/hda/files/sharename
- NOTE: Replace 1stadminuser with your admin user name and sharename with the actual share name.
