Fileserver

We are running a Fileserver at the space to store all kinds of stuff, as well as use it for generel data exchange (getting stuff to the laser, anyone?

Access

IP: 10.10.20.61

• There's a SMB (windows) share that should be writable to everyone. Try this \\10.10.20.61\share

Setup

We are running OpenMediaVault 3 (Erasmus) on Debian Jessie.

Hardware

• 2 Intel(R) Xeon(R) 5130 Dual Core @ 2.00GHz
• 6GB RAM
• 2x 150GB SATA Bootdrives built into case
• 8x 500GB SATA Drives in hotswappable bays
• 3ware 9550sxu-8lp RAID controller (for the 500GB drives, set in JBOD mode)

Software

We wanted to run the two boot drives in a software RAID1 array, so we had to install a barebones Debian system and then install OMV ontop, because the OMV installer disks do not seem to support this.

• Install Debian 8 from scratch, setting up the RAID1 in the process.
• Reinstall the bootloader on both drives (setup will only install on one)

dpkg-reconfigure grub-pc

• Install OpenMediaVault Erasmus (only version compatible with Debian Jessie at the time of installation)

 echo "deb http://packages.openmediavault.org/public erasmus main" > /etc/apt/sources.list.d/openmediavault.list
 apt-get update
 apt-get install openmediavault-keyring postfix
 apt-get update
 apt-get install openmediavault
 omv-initsystem

• Reboot
• Log into webinterface (User: admin, PW: openmediavault)
• Change the password

• Install ZFS plugin for OMV following this guide
  • The Plugin seems mature enough that you do not need to enable the ZFS testing repository, the normal one seems just fine
  • The installation of the plugin itself however did not go through completely on the webinterface. I was required to restart and finish the installation from the commandline with

dpkg --configure -a

• • So if you keep getting error messages in the WebUI after the installation, log onto the machine and run this until it produces no more output.

• Setup a ZFS pool: We just setup one pool with all 8 drives, as a RAIDZ2 (the disks are already a bit old). You can do it all on the WebUI, but it'll take time until the pool is initialized, and there's no status information, so just wait (took about 8 hours on our machine)
• Setup the Samba share
  • Go to the SMB/CIFS configuration on the WebUI
  • Enable the Samba service
  • Make sure "Null passwords" are enabled
  • Save
  • Go to "shares" and add a new share
  • Set permissions on the share to "Read/Write/Execute" for everyone (owner,group,others)
  • Set Public to "Only guests"
  • Activate "Browesable"
  • Activate "Recycle bin" if you feel like it (we haven't)
  • Save
  • Activate configuration

Post Reboot

The ZFS pool does not get mounted automatically when the machine starts. This leads to a bit of confusion, as the share is still available, but empty. Here's how to fix it:

• Login as root via SSH

umount /export /share
zfs mount internal
mount -a

Then everything should be fine again.
