Bellman is a Mini-ITX server. It is on a UPS and lives in my electronics lab.

Services that run here

  • X11 desktop so I can use it from my workbench.
  • cups to share MX330 and Pixma printers
  • Logitech squeezebox server
  • cacti to monitor network
  • asterisk to run our phones
  • ssh to allow remote access
  • fail2ban to cut off break in attempts
  • UPS daemon to monitor APC UPS
  • Netatalk to support Timemachine backups
  • owncloud server
  • mysql for asterisk and cacti
  • apache for cacti and owncloud

History

2015-07-01 - Replaced APC UPS with Cyberpower. Install monitoring software.

2015-06-19 - reconnected the MX330 printer and shared it.

2015-06-18 - upgraded to Debian 8 Jessie

2013-12-29 - returned from X-Mas and discovered Bellman won't boot. Snarks about a degraded RAID. Darn.

2013 Mar - Installed Linux Mint 14 so that I could use Makerware with my new Replicator 2

2013 Jan - Seagate Barracuda 2TB Green drive died. ST2000DL003 S/N 5YD77CTE Replaced with a Barracuda 2TB mirror

2011 Dec - Been doing PostGIS experiments so I upgraded the hardware.

2010 Jan - I just started this section but I have had this machine online for at least a couple years now.

2015-06-19 back up

Note this includes /home but not /green. 

cd /
tar --one-file-system czvf /mnt/bellman_root.tar.gz .

2013-12-29 Rescue from boot fail

I no longer need a desktop environment on the small server, because I moved my main desktop next to the 3D printer. So I put Debian back on the server again. So I am going to try a Debian rescue image.

Diagnosis

Step 1. Build rescue thumbdrive. Download from http://debian.osuosl.org/ and copy image to thumbdrive 

sudo cp debian-live-7.2-amd64-rescue.iso /dev/sdX
sudo sync
sudo eject /dev/sdX

where X is the appropriate drive letter, do NOT use the wrong letter!

Step 2. Boot Bellman with the thumbdrive

Step 3. Look around

Using hdparm -i

  • sda Vertex SSD S/N OCZ-9UDI676M56Z4IR8P
  • sdb Seagate 2TB ST2000DM001-9YN164 S/N Z240BVP5
  • sdc Seagate 2TB ST2000DM001-9YN164 S/N Z240A0H1
  • sdd rescue drive

sdb and sdc don't have partition tables as they are used in a RAID (see 2013 Jan entry)

Looks like there are 2 RAID's, and md126 is the broken one. It should be the SSD and something else? Time to open the box and see what's in there.

Command (m for help):

Conclusion - I was planning on doing RAID mirror and never got the second drive installed. I think I might have used it in Stellar instead. Steller's drive failed and needed immediate replacement. Something failed on the SSD and now it's not booting, but this has nothing to do with the hardware from what I can tell. It complains about the RAID missing a drive but that's not new.

2014 Jan 01 rebuild

Do as in the Linux Mint section below

Also note:

PRESERVE MYSQL!!

/etc/hdparm.conf

2013 Jan data mirror build

apt-get install mdadm lvm2
mdadm --create --metadata=0.90 --level=mirror --raid-devices=2 /dev/md0 /dev/sdb /dev/sdc
cat /proc/mdstat 
pvcreate /dev/md0 
vgcreate vg_mirror /dev/md0 
lvcreate --verbose --extents 100%FREE -n lv_mirror vg_mirror
mkfs.ext4 /dev/vg_mirror/lv_mirror 
mount /dev/vg_mirror/lv_mirror /green
dd if=/dev/zero of=/green/swapfile1 bs=1024 count=1048576

2013 Mar Linux Mint rebuild

Had to install mdadm and lvm2 but then it recognized the LVM drives All I had to do was mount the RAID on /green.

sudo apt-get install synaptic nfs-kernel-server ssh mysql-server phpmyadmin ntp winbind smartmontools postfix

Re-install dropbox

Re-install squeezeboxserver from Logitech. http://bellman:9000/

Set up cups again

Copy over /etc/exports file

Need AFP support for Apple Timemachine. See Netatalk 3 on Debian

December 2011 upgrade

Bellman had an Intel Little Falls Atom 230 mini-itx main board + 2GB RAM until Dec 2011. Bellman used to be an Athlon desktop system, I recycled the name because I like it.

Hardware

  • ASRock E350M1/USB3 AMD E-350 APU (1.6GHz, Dual-Core) AMD A50M Hudson M1 Mini ITX Motherboard $125
  • Kingston 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model KVR1333D3N9K2/8G $35
  • OCZ Vertex 3 120GB S/N OCZ-9UDI676M56Z4IR8P
  • Case: brand name?? need to look it up. Cost about $50 250W power supply
  • /dev/sdb Seagate Barracuda 2.0TB Model=ST2000DM001-9YN164, FwRev=CC4B, SerialNo=Z240BVP5
  • /dev/sdc Seagate Barracuda 2.0TB Model=ST2000DM001-9YN164, FwRev=CC4B, SerialNo=Z240A0H1
  • in USB enclosure: "Green" WD Caviar 500 GB drive. WDC WD5000AACS-00ZUB0 s/n WD-WCASU2227103

Video drivers

The ASRock card has an onboard AMD Radeon HD 6310 graphics chip. Therefore I need to follow these instructions: http://wiki.debian.org 

% lspci -v | grep VGA
00:01.0 VGA compatible controller: ATI Technologies Inc Device 9802 (prog-if 00 [VGA controller])

Flags: bus master, VGA palette snoop, 66MHz, medium devsel, latency 64

Dang but the aticonfig --initial command fails, unsupported hardware!

Maybe getting the driver from AMD support page will do it but I don't have time right now to deal with this.

See http://www.sensicomm.com/main/linux/acer_5253/index.shtml

Operating system

  • Debian 8
  • Was Linux Mint 14
  • Was Debian 6.0

Printing

Canon MX330 "All in one" -- CUPS finds and sets it up if you plug it in and power it on.

Software

Media server: it hosts my music collection. I keep the files in MP3 format, having transferred them from my CD's using grip. Music collection

File server: I keep my home directory here and NFS mount it on the desktop machine Raven. Bellman also runs Samba so that my laptop can access files on it.

I edit files with emacs23

Backups

I am about to try Using Bacula for backups
