So.... Yeah... Here's some advice if you're using rsync to transfer large datasets from an iMac Mavericks to a Drobo (or other NAS)

Don't use the built in rsync.

I was only getting 18Mb/s transfer from an attache WD 4Tb My Book.

That's crap to start with as it is USB3 and should be much higher.

I tried BlackMagic and what not and... nope... It's not running USB3.
Switched ports on the back of the iMac to see if it was a positional issue.
Nope.
Cable? Hmm. It's blue and says it's USB3...
In any case this post isn't about WD external drives, USB2/3 or iMacs or Mavericks.

It's about rsync.
And I was getting atrocious copy rates to my Drobos.
18-20Mb/s at best.
Gack!!!

So let's look at the installed version of rsync:

/usr/bin/rsync --version
rsync  version 2.6.9  protocol version 29
Copyright (C) 1996-2006 by Andrew Tridgell, Wayne Davison, and others.

What?

I have brew installed, so I did a brew install rsync.

/usr/local/bin/rsync --version
rsync  version 3.0.9  protocol version 30
Copyright (C) 1996-2011 by Andrew Tridgell, Wayne Davison, and others.

Better, but the surprise was that when I substituted the brew version for the installed version I went from 18-20Mb/s transfer rate to 40-100Mb/s (depending on the file size and file type of course).

It's not a perfect solution and doesn't explain why the WD 4Tb My Book has such atrocious rates, but I have no time to fiddle with that right now as I have 4Tb to transfer and 40-100 is better than 18-20.

So...
Yeah...
Suggestion: Install the brew version of rsync and use it instead.

Oh... Don't suggest putting a rsyncd service on the Drobos.
That's not the point.

I stopped the service and re-started it.

As soon as Galacticraft loaded, I got this warning.
What the hell?

Can someone please modify that warning to give some more indication as to why it occurs?

Please?

Well here is something fascinating about DroboFS devices.

Had a problem.
With a very old DroboFS.
We have two, named Moya and Lexx, which if you aren't familiar with... Oh WTH. Go look it up.

In any case...
Moya started developing some issues.
Strange responses, 'name too long' and so on.
Tried to delete krap folders without effect.
Eventually the device went west.

Removed drives, rebooted, all ok.
Latest firmware.
Drives back in in exactly the same positions.
Same issue.
Device reboots constantly, all drive bays lit up like christmas.

Hmm.
Ok.
Other DroboFS.
rsync'd all data off it.
Removed drives.
Booted it.
Dashboard shows it as Lexx.
Ok.
(This took nearly a week I might add. Old Drobos aren't quick on the network front)

Inserted all drives in exact same positions from Moya and booted.
Watched with bated breath at the Drobo dashboard.
Wait.
What?
The device changes it's identity to Moya.
Even the IP address changed.
Wait.
What?

Ok. You learn something every day.
Currently rsync'ing all the data off it in prep for a complete burn.

Also, and somewhat off-topic, been reading up on MTBF of various brands of drives.
All the drives in Moya and Lexx are Seagate Barracuda 2 and 3Tb.

No more, she said!

After such a good experience with the Synology DS214SE with WD 3Tb Red NAS drives, I'm switching.
I'm going to pimp out these old Drobos with WD from now on.

This wasn't covered in YouTuber 101...

I...
Wait...
What?
Oh lord.
I have to take 36min capture, cut it up into smaller chunks using iMovie '09.
Then export them to separate MOVs.
Then upload them individually into YT.
It's the waiting.
The waiting.
The waiting.
Th endless, take a shotgun, two shells and call me in the morning waiting.
Oh lord.
Recording it was easy.
Editing, cutting and uploading is a PITA.

Movie upload failed


Seriously.
Why?
This leads you to:

https://www.youtube.com/watch?v=OD8CJ9Pa-SY&feature=youtube_gdata_player

Which says:


The video you have requested is not available.

WTF?
So WHY is the upload failing?
YouTube?
Anything?
Uthgar?
Anything?
WHY?

The Sheer Ham Fisted Genius Of Belkin Designers!

Ok.
Bought a new window mount because Ben wants to have his iPhone attached to the window of the car.
Belkin.
The genius of it.
Here's the box:



Now we open it as any NORMAL PERSON WOULD DO.

And this is what we see:



The sheer genius of it.
INSIDE the top of the box.
Not OUTSIDE.
INSIDE.

Look and be stunned.

Or amazed.
Or LOL.
Or ROTFL.

Whatever.

Give Me GigBit NetWorking OR Give Me Freedom!

Oh Lord.
Trying to frantically backup a DroboFS to a Synology DS214SE.
The latter, I have to say, was a brilliant purchase.
But networking.
Networking.
Sigh.
GigaBit Networking required.
And I only have 10/100.
Expensive weekend I fear,

Mincraft - Series 2 A Mob Interlude - complete

Series 02 - A Mob Interlude is now complete.
A tad dry but fun dialogue.
Plus I make a massive mistake between D H Lawrence and H P Lovecraft.
Wait.
What?
Yes really.
Joy of joys.
But I make amends with the last video.

Why certain practices in companies stay the way they are despite being silly.

Two points:

This story illustrates the point succinctly.

2) I have a personal non-work example.
When I was very young in the early 60's we didn't have a 'cooker'.
We had a coal fireplace and 'hobs' which were swinging cast-iron arms that moved over the fire.
You put kettles, pots etc on them and your food got cooked.

For several years we moved from house to house and then to Australia in 1968.

It had a gas cooker that was so big you could put a side of beef in.
I watched my mother get a roast ready.
She got the roast and cut the top third off and placed the 2/3rd and 1/3rd next to each other in a tray.
I wondered why, but didn't ask her why.

Then in 1977 I travelled to the UK and visited my Aunt and Uncle.
My Aunt did exactly the same thing my mother did.
2/3rd 1/3rd of a roast in a tray.

Later that year I visited my GrandParents.
To my total surprise I saw her do the same thing.
I asked why.
Her response:

"When I was young we only had a cooker that was about 4 inches tall run by coal.
So I cut the top off the roast so that it would fit.
I just haven't changed."

Ah. I see.
We tend to do the same things because other people do it that way because of some reason that doesn't matter anymore.


So. Re-evaluation time for your habits.
