You can resume a send if the destination has a snapshot in common with the
source. If you don't, there's nothing you can do.
It probably taking a while to restart because the sends that were
interrupted need to be rolled back.

Hallo again,
I'm wondering how one would get the serial numbers for a HDD to identify them
via OpenSolaris and match them to the ZFS pool.
Like I'm trying to workout which HDD c7t3d0 reliably. Can serial numbers be
read by OpenSolaris?
Cheers,
Andre
yah, unfortunately this is the first send. i'm trying to send 9 TB of data.
It really sucks because i was at 6 TB when it lost power

I should mention that iostat -En doesn't return any information. Is there a
reliable way of reading SMART information natively in OpenSolaris?

There is no package for it but it's EASY to install
once you do, you can get ouput like this:
pfexec /usr/local/sbin/smartctl -d sat,12 -a /dev/rdsk/c5t0d0
smartctl 5.39.1 2010-01-28 r3054 [i386-pc-solaris2.11] (local build)

Thanks Thomas, I thought there'd already be a package in the repo for it.

i do have snapshots, but i only keep them for when/if i accidently delete

I am new to OSOL/ZFS but have just finished building my first system.
I detailed the system setup here:
http://opensolaris.org/jive/thread.jspa?threadID=128986tstart=15
I ended up having to add an additional controller card as two ports on the
motherboard did not work as standard Sata port.
iostat -xen 1 will provide the same device names as the rest of the system
(as well as show error columns).
zpool status will show you which drive is in which pool.
As for the controllers, cfgadm -al groups them nicely.

This didn't work for me. I had the exact same issue a few days ago.
My motherboard had the following:

I thought i needed this to use both the ide and ant sata ports, turns out it

Ok. What worked for me was booting with the live CD and doing:
pfexec zpool import -f rpool
reboot
After that I was able to boot with AHCI enabled. The performance issues I was
seeing are now also gone. I am getting around 100 to 110 MB/s during a scrub.
Scrubs are completing in 20 minutes
