Using to connect to the serial cable to my test pogobox.  Let's me see what is going on in a plugbox boot up.

Referenced in the plugbox link:

http://plugapps.com/index.php5/Hardware:_Pogoplug_Pro_Serial

The log notes on June 6 and 7, 2011 talk about how I used it.

This is being used to work with running iRODS under plugbox for the NARA Advance Language Processing (ALP) work the Bill Underwood.

There should also be something

There are some other links I should have saved that clued me in that the power was coming from Pogoplug and not the USB port.

Not for a Pogoplug, but does go into some good detail:  http://www.google.com/url?sa=t&source=web&cd=11&ved=0CCwQFjAAOAo&url=http%3A%2F%2Fwww.neolics.com%2Fpdfs%2Fdku-5.pdf&ei=BUECTu2VDJOitge20aHIDg&usg=AFQjCNE6q5HNSrRW58jfsSvfdpOWKMHRqQ&sig2=uPCVDWt6LqxFwlzKb5ARxA

Just a short not at the bottom: http://www.pogoplugged.com/forum/thread/11515/How-To-Find-mkfs-jffs2-and-other-tools-on-Pogoplug/?page=2#1692

I was unable to find the article that I was looking for :-(

3TB Drive for $140 (< $50 per TB)

http://www.buy.com/prod/western-digital-my-book-essential-3tb-usb-3-0-external-desktop-hard/q/loc/101/217438518.html

The sweet spot seems to be moving to the 3TB drives.  With free shipping this is at $47 per TB.  Also this would increase our current system from  8TB per plugbox to 12TB per plugbox.

Linux: Pogoplug: memory

To see the memory in a Linux system using the following command.

 free

Using the '-m' option will show it in megabytes.  Note this option doesn't work in the busybox; however, it does work in Ark Linux.

BusyBox link:

http://www.busybox.net/about.html

Ark Linux link:

http://www.archlinux.org/

Man page for 'free' command.

http://linux.die.net/man/1/free

On the Pogoplug pink (version 2) the memory is a follows:

• Running iRODS slave server:  50600k of 252928k (49mb of 247 mb) used
• Without iRODS:  50972k of 252928

That is amazing.  The iRODS portion is only 172k.

• Without iRODS:  

Using Arch Linux: Pacman, hostname, time

pacman

The main command to run to keep everything up-to-date is:

• pacman -Syu
• '-S' - synchronize packages
• '-y'  - down load a fresh copy of the master package list from the server(s).  Usually used with the 'u' option.
• '-u'  - upgrade all packages that are out of date.

This is the man page:

http://www.archlinux.org/pacman/pacman.8.html

hostname

Setting the host name seems to be straight forward in Arch Linux.

Set the 'HOSTNAME' variable in the /etc/rc.conf file.

 HOSTNAME="Plugbox"

Map the new name in the /etc/hosts file.

 # # /etc/hosts: static lookup table for host names #  #<ip-address>	<hostname.domain.org>	<hostname> 127.0.0.1	localhost.localdomain	localhost gtripg01 ::1		localhost.localdomain	localhost gtripg01 #127.0.0.1	Plugbox  # End of file 

Much of this information was confirmed or gleaned from this thread:

https://bbs.archlinux.org/viewtopic.php?pid=267786

time

This will take some time today.  I will just gather the links for now.

The Arch Linux page on time with some nice links at the bottom.

https://wiki.archlinux.org/index.php/Time

The LinuxSA page on time.  Talks about 'rdate' and its replacement 'xntpd'

http://www.linuxsa.org.au/tips/time.html

General pages on time and time jargon:

http://www.ucolick.org/~sla/leapsecs/timescales.html

http://en.wikipedia.org/wiki/Time

I now know enough to find the correct page for setting time in PlugApps:

http://www.plugapps.com/index.php5/Application:OpenNTPD

I am not sure what the 'configuration file' is or where it is, but I will try to figure that out with I install the 'openntpd' package.

 pacman -Sy openntpd

Pogoplug Mounting a stock Image as RW

http://www.plugapps.com/index.php5/PlugApps:Pogoplug_Pro_Chroot

The command is:

Example and a site in TX that actually works.

The man page

https://aur.archlinux.org/packages.php?K=rdate

I tried to get 'rdate' using the pacman tool.  It took a little bit before I realized that I need to download and install the package.

Added the following line to the rc.local file (/etc/rc.local)

Figuring Out Devices and Storage on the Pogoplug

On a normal Pogoplug V2 4 USB storage devices looks like this:

-bash-3.2# df

Filesystem           1k-blocks      Used Available Use% Mounted on

/dev/mtdblock2           32768     15872     16896  48% /

none                    128004        12    127992   0% /tmp

/tmp/.cemnt/sda1     1953512000    125684 1953386316   0% /tmp/.cemnt/mnt_sda1

/tmp/.cemnt/sdb1     1953512000    125732 1953386268   0% /tmp/.cemnt/mnt_sdb1

/tmp/.cemnt/sdc1     1953512000    125732 1953386268   0% /tmp/.cemnt/mnt_sdc1

/tmp/.cemnt/sdd1     1953512000    125732 1953386268   0% /tmp/.cemnt/mnt_sdd1

OK, this makes sense.

-bash-3.2# /sbin/fdisk /tmp/.cemnt/sda

The number of cylinders for this disk is set to 243201.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /tmp/.cemnt/sda: 2000.3 GB, 2000398934016 bytes

255 heads, 63 sectors/track, 243201 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

          Device Boot      Start         End      Blocks  Id System

/tmp/.cemnt/sda1               1      243201  1953512001   7 HPFS/NTFS

OK, it see the USB devices.  Now I have to get it to mount them.  I can do that later.

Getting Disk Info

 df -h

 fdisk -l hdparm -i device (probably /dev/hda)

 Using the 'sudo hdparm -i /sda' command I was able to get the following data:

 /dev/sda:   Model=WDC, FwRev=01.04A01, SerialNo=WD-WXEY07X26552  Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }  RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=50  BuffType=unknown, BuffSize=8192kB, MaxMultSect=16, MultSect=16  CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=312581808  IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}  PIO modes:  pio0 pio3 pio4   DMA modes:  mdma0 mdma1 mdma2   UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5   AdvancedPM=yes: unknown setting WriteCache=enabled  Drive conforms to: Unspecified:  ATA/ATAPI-1,2,3,4,5,6,7   * signifies the current active mode 

 However, this didn't work for the new Fantom Drives.  I get the following error instead:

 /dev/sdb:  HDIO_DRIVE_CMD(identify) failed: Invalid exchange  HDIO_GET_IDENTITY failed: Invalid argument 

I would guess that this has something to do with it being a USB drive.

Will this be fixed by USB3?

How did linux know if was a Fantom Drive?

USB Info

Using 'lsusb --verbose' I still don't see anything that would enable to ID drive.

Crash Course for iRODS Commands

I had to refresh myself today to do some simple work in iRODS.

Main command is 'iadmin'

Main command for environment is 'ienv'

Main command for starting and stopping is 'irodsctl'

This was enough to get me through.

Setting Up Environment Variables

Need to setup my environment to use the iRODS icommands and control command.  Added the following lines to the bottom of the ~/.bashrc file.

# add poath for iRODS icommands

export PATH=$PATH:~/iRODS/clients/icommands/bin

# add pa;th for iRODS mangment commands

export PATH=$PATH:~/iRODS

(note:  I replace implicit path '~' with the actual)

Steps to Building a Pogoplug iRODS: Prepare USB Boot Disk

The notes are a little sparse on the Pogoplug site.

Starting at this link:

http://www.pogoplug.com/home-en-developers-open-source.html

I believe that I am working with a Pgogoplug V2.

The Pogoplug Pro stuff using Linux kernel version 2.6.31.6.

The Pogoplug V2, Pogoplug Biz, and Pogoplug V1 using Linux kernel version 2.6.22.18.

This doesn't match what I read on the web.

OK, part of this is to load the U-Boot boot loader onto the Pogoplug.

The format of the USB drive is being done from the Pogoplug itself.

.

Instead of creating the USB boot drive from the Pogoplug, I am going to be doing it from my linux box

You can't tell that the pogoplug processes have been killed.

What is the current system?

Linux Pogoplug 2.6.22.18 #44 Mon Aug 10 12:57:36 PDT 2009 armv5tejl unknown

Didn't add the boot loader.

Trying to reboot.

It doesn't seem to be coming back.
