[OpenIndiana-discuss] Zpool upgrade didn't seem to upgrade

Morning!

Yes, the peaks were triggered by the resiver.

I don't have enough connections to hook everything together at the same time.

Also, I performed the trick with memory sticks. Here is a demo video I made...
http://www.youtube.com/watch?v=RmtPpnSrJ6w
... once all the 4gig sticks were replaced with 8 gig sticks, simply exporting 
and then importing the pool resulted in the extra space becoming available.

For some reason, it didn't want to work with the 2tb drives.

It is my home server. The one that keeps all my data, photography RAW files, 
music, programs, code, everything going back to when I started with computers 
in my teens.

I was on a Sun course (prior to the Oracle take over) which covered ZFS as 
part of it. It really captured my imagination. Hence I did a load of testing 
with memory sticks and even made videos to say, "Hey, how cool is this!"

But it is odd things like this which are really throwing me curve balls.

> Fourth... what would you like to achieve with OI ?

<engage violins> On a small wage, I can not do much. After dealing with cheap 
RAID cards over the years, I lost a lot of data because the embedded control 
was near impossible to work with. I had back ups fortunately, but as data 
sizes grew, I couldn't afford the larger tape backup systems. ZFS seemed like 
the perfect answer for one as poor as I. <end violins>

With the killing of OS for the home user (due to the licence prohibiting 
production box of Express 11 ... it made no distinction for home users at all 
... so I had to move from OS) I did a bit of research and believe that OI is 
the obvious replacement for OS. 

Not because of the technology ... but because of the community. The e-mails 
and the help I have received over IRC have been wonderfully supportive, and 
tolerant of me.

So, I have chosen to use OI to keep all my data safe with ZFS. E-sata cards 
for an external backup system that I can put two drives in, so I can back up 
to a ZFS mirror set.

Seems like the ideal solution that will grow with me. 

I've actually achieved what I want with OI, a home server that seems stable. 
It is just odd behaviours that are throwing me a little.

> Sorry now i made four Questions out of it.  ;)

No problem :-)

Many thanks for any help you can give me on this.
