OpenMediaVault

  • Install & Configure openmediavault (omv6) | DIY NAS Part 3 - Software 2023/4/21. Quite complete !!
    • Set up Users first before messing up folders. The order is similar to the way clients access shared folders.
    • After creating a shared folder in Storage menu, go back to Users menu. Select a user and click "Shared folder privileges". Click on "Read/Write" to enable it (Yellow).
    • Go back to the shared folder. Click on "Privileges" icon. We can verify who has what kind of privileges.
    • After generating "Shared folders", we still need to go to Services and enable NFS or SMB/CIFS. This is two steps: one is to enable it and the other is to add individual shared folders to either SMB or NFS.
    • Now it's time to verify the shared folder on client machines.

Disk space and memory requirement

For disk space, 4GB is enough. It shows 2.4GB in my OMV 6.5.0.

The memory usage is 430MB when in idle.

Network, static IP & DNS for internet access

  • Remember to change DNS in the Advanced section. No need to modify anything in /etc/resolv.conf in terminal. You can check that "ping -c 3 1.1.1.1" works but "ping -c 3 google.com" did not.
  • Configure DNS is necessary when I need to install plugins.

apt update warnings

You still have the security repo in /etc/apt/sources.list. That needs to be removed.

Disk usage

  • Method1: Dashboard - File systems (/dev/sda1, /dev/sdb1, ...)
  • Method2: Storage - File systems

Sharing

  • We need to partition the system disk if we want to create a shared folder on the system drive. shared folder on the system disk.
  • share whole disk (it works)
  • Remember to create a new user (it seems admin is not working for share folders). When I create a new user (Groups = users) after I created a shared folder, the new user automatically appeared in a shared folder Permissions list.
    • No need to create home directory from "Users - Settings".
    • Create a user from "Users - Users". Enter a user name. In the Group attribute, select Users. That is enough.
    • No need to worry from "Users - Groups".
  • Storage - Shared Folders. Create a name.

Where are shared folders

In OpenMediaVault, shared folders are a key functionality around which all services revolve. They are created as subvolumes on BTRFS file systems or simple directories on all other file systems supported by OpenMediaVault.

When you create a shared folder, you select a disk, and then a folder on that disk. If the folder doesn't exist, it is created for you². That's where the shared folder is located.

The actual path of the shared folder can be obtained using the UUID of the shared folder. On my OMV running in Proxmox, 

root@omv:~# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0   32G  0 disk 
├─sda1   8:1    0   31G  0 part /
├─sda2   8:2    0    1K  0 part 
└─sda5   8:5    0  975M  0 part [SWAP]
sdb      8:16   0  489G  0 disk 
└─sdb1   8:17   0  489G  0 part /srv/dev-disk-by-uuid-9c8dfd73-766f-49c0-acb4-2a26c1c2172c

root@omv:~# ls -l /srv/dev-disk-by-uuid-9c8dfd73-766f-49c0-acb4-2a26c1c2172c/
total 36

drwxrwsr-x 2 root users  4096 Oct 19 07:40 OPMShare    <== Share name for a folder

Remove SMB sharing

  • (Necessary?) Plugin - type 'reset' (resetperm) - Install.
  • Step 1: Services - SMB/CIFS - Shares - click one and delete
  • Step 2: Storage - Shared folders - click one and delete.
  • Step 3: Apply the changes.

Note although we remove SMB shares, the Dashboard still shows the disk and its partitions. The Storage still shows the device.

Update

apt-get update && apt-get dist-upgrade && omv-update

omv-release-upgrade

SMART monitoring

After enabling SMART monitoring in OpenMediaVault, you can do the following:

  • View device information: From the Devices tab, you can select a drive and click on the Information button to view detailed information about the drive, including its SMART attributes and status.
  • Configure notifications: You can configure OpenMediaVault to send you email notifications when changes in S.M.A.R.T values are detected. To do this, go to the System tab in the left-hand menu, select the Notification option, and configure your email settings.
  • Schedule tests: From the Scheduled tests tab, you can schedule different types of tests to run on your drives, including short self-tests, long self-tests, conveyance self-tests, and offline immediate tests.

NAS Not seen/visible in local network

Ideally, if we go to the File Manager app -> Network (Windows)/Other Locations (GNOME) we shall see "HOSTNAME -SMB/CIFS" & "HOSTNAME - SSH" items. If we click on "HOSTNAME - SMB/CIFS", it will show the shared folder name.

View free/total space in client

PS. I don't this problem. To view free space, right click on any one of subfolders and choose Properties. It'll show "Free space" (at least on the GNOME file manager).

Unable to show real free/used disk space in SAMBA mounted drives under Windows. So add this line (OMV GUI) to the Extra options-field (bottom of the screen) in 'Edit share' and restart the samba service (systemctl restart smbd.service). It´s a per share command. 

dfree command = /usr/local/bin/dfree

Create a file /usr/local/bin/dfree and make it executable. 

#!/bin/sh
/bin/df -h $1 | grep sda1 | awk '{print $2" "$4}'
# 458G 241G

OMV-Extras

FileBrowser

  • Step 1: System - Plugins
  • Step 2: Services - File browser. Enable it. Port is 3670. Need to select a Shared folder. Save & OpenUI. Default is admin/admin. We can download/upload/copy/paste/delete/... files, create new files/folders, manage users, through the web interface.
  • The filebrowser cannot even preview png files like a regular file manager in a desktop

aquota.user, aquota.group

You can't remove them because they are in use by the quota service.

Install ArchLinux on pogoplug (Debian is better actually)

See the instruction in http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray for how to install Archlinux on pogoplug (E02). I make a copy below. 

killall hbwd
cd /tmp
wget http://jeff.doozan.com/debian/uboot/install_uboot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh
/sbin/fdisk /dev/sda

At the fdisk prompt, delete old partitions and create a new one:

  • Type o. This will clear out any partitions on the drive.
  • Type p to list partitions. There should be no partitions left.
  • Now type n, then p for primary, 1 for the first partition on the drive, and then press ENTER, accepting default values.
  • Exit by typing w.
wget http://archlinuxarm.org/os/pogoplug/mke2fs
chmod 755 mke2fs
./mke2fs /dev/sda1
mkdir usb
mount /dev/sda1 usb
cd usb
wget http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz
tar -xzvf ArchLinuxARM-armv5te-*.tar.gz  # This will take a long time
rm ArchLinuxARM-armv5te-*.tar.gz
sync  # Takes a while when using a flash drive. Not in my case however.
cd ..
umount usb
/sbin/reboot

Log back in after your Pogoplug reboots using username root and password root.

At the end, the system is very lean.

Install Debian on pogoplug

See the instruction on http://projects.doozan.com/debian.

  • Find your devices's IP address and connect via SSH:
  • Partition your flash drive with fdisk (or gparted):
fdisk /dev/sda
# Configure partion 1 as Linux (I'd recommend making this at least 512Mb. The default bare-bones installation uses 280Mb.)
# Configure partion 2 as Linux Swap (I used 256MB.  Adjust according to your anticipated memory usage.)
# Set partition 1 active

See http://www.terminally-incoherent.com/blog/2012/09/19/set-up-a-home-linux-server-for-30-with-pogoplug/ for clear explanation of using fdisk.

  • Download and run the Debian Wheezy installer:
cd /tmp
wget http://projects.doozan.com/debian/kirkwood.debian-wheezy.sh
chmod +x kirkwood.debian-wheezy.sh
export PATH=$PATH:/usr/sbin:/sbin
./kirkwood.debian-wheezy.sh
  • Alternatively, you can choose to install Debian Squeeze with the following commands:
cd /tmp
wget http://projects.doozan.com/debian/dockstar.debian-squeeze.sh
chmod +x dockstar.debian-squeeze.sh
export PATH=$PATH:/usr/sbin:/sbin
./dockstar.debian-squeeze.sh

The script will take some time to download the debian images and extract them to your flash drive. The total install time will vary with the speed of your flash drive and your Internet connection. On my system, it takes about 20 minutes. Once it's finished, you can reboot into your new Debian install.

After your device reboots, it may have a different IP address (it's identifying as 'Debian' to the DHCP server now instead of 'Pogoplug').

The default root password in Debian is 'root'. After you've logged in, you should change the root password and configure /etc/apt/sources.list to point to a Debian mirror near you. 

passwd
nano /etc/apt/sources.list

After reboot, the debian system is very lean too

After I install LAMP, the memory uses 250MB. However, after I reboot the pogoplug, it reduces to 66MB.

If I want to add a USB drive, it is safe NOT to insert the 2nd USB drive when the system boot. It is better to insert the 2nd USB drive after the system has booted. In my experience, if I insert the 2nd USB drive when the system boot, the first USB drive will be mounted as /dev/sdb1 but I want the 2nd USB drive mounted as /dev/sdb1.

Install build-essential. Should be fine. See Home automation link below.

BitTorrent by Transmission

Note: Must stop the transmission-daemon before modifying the setting. 

apt-get install transmission-cli transmission-common transmission-daemon
# stop transmission first before change the setting
/etc/init.d/transmission-daemon stop
nano /etc/transmission-daemon/settings.json
# change “download-dir”, “incomplete-dir”
# change rpc-whitelist to "*" or your remote IP
# change "rpc-username" ,
#        "rpc-password"  (this will then be hashed, so don't worry)
# change "speed-limit-up": 10,
#        "speed-limit-up-enabled": true,
# change upload-limit (KB/s) from 100 to 10
#        upload-limit-enabled from 0 to 1
mkdir /mnt/usb/Downloads
chmod -R 777 /mnt/usb/Downloads
transmission-daemon 

/etc/init.d/transmission-daemon stop

# Remember to shut down transmission before editing the settings.json file

/etc/init.d/transmission-daemon start

Open browser http://hostname:9091/transmission/web

For pirat*, we can download torr* by using (see here) 

http://torrents.thepiratebay.se/xxxxxx/My.torrent

So we don't need to download the torrent in our local machine. In fact, we can just right click 'Get this torrent' button and copy the link. Then we can open the url in transmission/web.

Note: the transfer speed from pogoplug to ubuntu is about 5.5MB/s.

SFTP server by Cyberduck

WebDAV by owncloud.org

SAMBA server

So every computer in LAN can access the contents there. On Windows computer, type \\192.168.1.3\ShareFolder, for example.

  • UPnP media server will stream the media content on your Pogoplug to any compatible media player such as the PlayStation 3, Microsoft Xbox 360, and D-Link Boxee Box over your local network.

NAS4Free vs FreeNAS vs Amahi vs OpenMediaVault

NAS4Free

  • NAS4Free from pcworld.com.
  • FreeNAS and UPnP setups from homemultimedianetwork.com.
  • A non-English youtube video demonstrates installing NAS4Free on Virtualbox (it works as I tested). The important thing is the NAS4Free is based on BSD. So we should select BSD & 64-bit instead Linux. I am using NAS4Free-x64-LivdCD-9.3.0.2.1349.iso. N.B. NAS4Free does not take much space as, saying, Ubuntu. See the next screenshot.

NAS4Free64.png

  • WebGUI interface and setup.
  • After I enable ssh and allows root login, I can see the default shell is tcsh. See the document in here.
  • If we have added IDE disks from virtual machine setting, we can add them using the web management. To do that, we need to Add disk by clicking '+' sign, apply changes, format disks, and mount disks (mount point name can be 'Data1', 'Data2', ...). These disks will be available via /mnt/Data1 or /mnt/Data2. See the document in here.
  • Lots of services: CIFS/SMB (Samba v4.x), FTP, NFS, TFTP, AFP, RSYNC, Unison, iSCSI (initiator and target), HAST, CARP, Bridge, UPnP, Webserver, and Bittorent.
  • UPnP service works like a charm. Note that I need to check the checkbox in 'Enable' (on the topright corner) for it to work. On the client side, I use ubuntu's VLC (v2.1.4) to test. In VLC, click View -> Playlist ('Ctrl+l') and then select Local Network -> Universal Plug 'n' Play. I have tested streaming mp3 and mp4 files. For Android devices, we can try the BubbleUPnP app.
  • How do I stream photos? Photos do not show up on VLC or Android UPnP software like BubbleUPnP, AirWire. The trick is to click Administrative Webgui url link and then click rebuild/update database. After the fix, VLC can play photos as video (10 seconds for each) automatically and BubbleUPnP can play the photos too (users decide how long to stay on one image).
