Drobo S not seen by drobo-utils, larger than 2TB ext3?

[Keith]

Just got a Drobo S, it's my first Drobo so I don't have prior
experience with drobo-utils but it seems easy enough.

OS: Ubuntu 9.10 32bit
drobo-utils: 0.6.1

Problem 1: "No Drobos discovered"
Any droboview or drobom command gets me "No Drobos discovered". I'm
guessing it's because this version of the Drobo doesn't have support
yet in the drobo-utils, but I'm not sure.

Currently I'm using USB to connect. For testing I tried the drobo
software on Mac and Windows and they both were able to find and setup
my initial 2TB partition. Ubuntu now sees the Drobo and I can use it
as expected, but drobo-utils still do not work.

Problem 2: "Larger than 2TB EXT3 partitions"
From what I understand I can make larger than 2TB EXT3 partitions with
the Drobo S, but I don't know for sure.

I'd like to use ext3 as the filesystem, but I'm not sure of the safest
way to do that without using drobo-utils. From what I've seen on
other forum posts I shouldn't make larger than 2TB ext3 partitions,
but I'm hoping the Drobo S versions gets past that. Thanks for any
suggestions.

Not detected... Please run:

drobom -v 16 status

and post the output. Probably the vendor string has changed again.

OK. so the problem is that the "vendor" reported here is "Drobo..."
In the past it was "TRUSTED DATA", then it became "DROBO", now it is
mixed case... sigh...

If you are installed from a package, then probably the easiest thing
to do is go
edit:

/usr/share/python-support/drobo-utils/DroboIOctl.py

find the line around 318...

if ( id[4].startswith("TRUSTED") or id[4].startswith
("DROBO") )

and change DROBO to Drobo.

see if it works.

[Peter.A.Silva]

if you install from git, then

git pull

will get you a real patched version.

Sweet! The CLI works now, but the GUI is spitting out some errors and
won't launch. I've double checked the requirements and seem to have
all of them. Here is the error I get when trying to launch GUI:

it would be really helpful if you could do:

git clone git://drobo-utils.git.sourceforge.net/gitroot/drobo-utils/drobo-utils

cd drobo-utils

[Peter Silva]

very odd that it says 'invalid option: slots'
works fine here... also, it ran the same routine
and did not fail...

./drobom info slots    (without the -v)

paste output.

[Keith]

If there is anything else you think I should try, or that you'd like
me to test let me know. I've got nothing important on it yet so I can
wipe it and try different things if needed.

Here you go:

[Peter Silva]

please run
 
./drobom info

then try the GUI
./drobom view

see if it works.  The 'slots' thing is really strange.

do python -V.

'pull again' means you have to do:

Peter,

Ok I git pull but I am noobing here
When I sudo ./droboview

I tried export PATH="/home/me/src/drobo-utils:${PATH}" but not working

Can you please help me.

Hello Peter,

I connected the drobo to its droboshare and plugged this latest to the
LAN (no direct usb cnx)
Now when I

$ sudo ./drobom info
No Drobos discovered

or
$ sudo ./drobom view
Please try again as root.

Thank you,
Laurent

[Co Landscape]

[Peter Silva]

drobo-utils is only for locally attached linux systems, not droboshare.

If you are comfortable with line mode, then Droboshare Augmented root file system (darfs) will get you some functionality.   You could download darfs, and then apply an updated drobo-utils on top of it.  This will give you drobom working when you log into the share directly, the ability to update firmware, etc... but no GUI.

[Keith]

Still can't seem to get the GUI to work. Using the commandline I told
drobom to reformat as ext3, which seemed to work ok. But still same

FYI, for testing I tried droboview with python 2.4, 2.5 and 2.6. 2.5
and 2.6 both work the same, drobom all works great it seems except for
the GUI. 2.4 has other problems and can't do a basic drobom info.
Let me know if there is anything you'd like me to try.

EXT3 question:

Earlier when I wanted to make it ext3 I ran "./drobom format ext3" but
the script shows :

#!/bin/sh
parted -s /dev/sdc mklabel gpt
parted -s /dev/sdc mkpart ext2 0 100%
parted -s /dev/sdc print; sleep 5
mke2fs -j -i 262144 -L Drobo01 -m 0 -O sparse_super,^resize_inode /dev/
sdc1

Wasn't it supposed to be ext3? After I run that script when I do
"drobom info" it looks like it shows the filesystem as NTFS. Here is
the output:

# ./drobom info
---------------------------------------------------------
Drobo Name: Drobo S Devices: /dev/sdc

Time: Fri Dec 25 05:03:46 2009

Thanks for any info,

[Peter Silva]

I think you are using an older revision, and that the issues you are seeing are already addressed, but not sure.

Please confirm you have updated your source code.  The command to do that is:

git pull

don't bother trying the GUI until info slots works.

I just did a git pull and still get the "tuple index out of range"

I'm sorry it's taking so long, but things should be
simpler now, as this is the only issue I will look
at until it gets settled.  Hope you have some patience left.  Without equipment and only limited telepathy,
this might take some time...

It isn't worth trying the GUI until the line mode stuff works.   The thing which is messed up is 'info slots'.
This part of your previous report was strange:

"invalid info option: slots
valid options:  config, capacity, protocol, slots, firmware, status,
options, luns "

This message should not occur with current version.
I added some other debug output.  Please

git pull

again, then supply output of:

drobom info slots

Ok, just did a git pull. The CLI output is below. Couple other
things, just got a eSATA card, and drobo-utils doesn't see drobo
(Ubunutu see's it though). I also got a new drive so I can test using
partitions larger than 2TB. Once the tool is working right I'll start
testing partition sizes and speed.

ok
git pull

again,
then

drobom -v 12 info slots

All works well now after the latest git pull. GUI and CLI work
without giving me the python tuple errors.

Thanks for all the hard work with drobo-utils, knowing it was there
was one of the reasons I bought the Drobo in the first place. Without
decent tools in Linux (like drobo-utils) it wouldn't be worth using.

Thanks,

Now that drobo-utils is working great with my Drobo S, I'd like to
test creating LUN's larger than 2TB. The GUI locks it down at 2TB, so
what's the proper way to create a LUN larger than 2TB?

Also, what tests should I preform so I know if the LUN works
correctly? From what I understand I fill the LUN up with data and see
if the speed is still good past 2TB, then try to delete items and see
if I get the disk space back correctly. Anything else that would be
good to try?

With my setup, the drobo capacity calculator (http://www.drobo.com/
calculator/drobo-s/index.php) says I'll have 2.72 TB available for
data, actual size of 4.5TB.

Thanks,

Keith

Wohoo, larger than 2TB with ext3 seems to work well. I created a 8TB
(2.7TB usable) virtual LUN following the instructions here:

http://www.backupcentral.com/content/view/283/47/

I loaded the LUN up with about 2.2 TB of data and speed was
consistent. After that I deleted 1.5TB of that data which worked, but
it seemed to take about 1/2 a day for the drobo blue lights to reflect
the files I deleted. I noticed though in the GUI I can see the drobo
doing a "Status: update: XXXX" which I'm guessing is the Drobo
updating itself to reflect the files I deleted.

[Peter Silva]

It's normal for it to take time to update after a delete.

I don't know the algorithm for reclaiming space, but it

is that way on all OS's.

the status: update thing... is just a count, from the GUI.

every 5 seconds or so, the GUI polls the drobo.

Each poll increments the count by one.

nothing to do with the drobo itself.
