I mounted wrong zfs pool.

I've seen this error often, but mostly the volume is shared.
I think it happens as soon ay the volume has snapshots.
To check if the volume is exposed or not, you can run:
iscsitadm list target -v
If the volume shows up, it's OK and you should ignore the message.

What is less clear is why windows write performance drops to zero.
Perhaps the tweak for Nagel's Algorithm in Windows would be in order?

Scott, thank you so much for the testing spirit and sharing the result with
the list! -- We architects can be talking all day long and still don't have
any idea how the open things would work on any box, not just the
poster-boy
My son (15 years old) has installed OpenSolaris 2008.11 on disk on
his system and everything was OK until he made a newbie mistake and
edited the /etc/vfstab file incorrectly, that now prevents him from
booting. (Think he had done too much Linux...)
It just hangs on the splash screen.
My idea was
If you have snapshots of the root filesystem, you can recover the file.
To check for snapshots run:
zfs list - t all
If you see something like
rpool/ROOT/opensola...@x
then you are lucky, you will find the original vfstab file in:
/b/.zfs/snapshotname/etc/vfstab

thanks for your responses, guys...
the nagle's tweak is the first thing i did, actually.
not sure what the network limiting factors could be here... there's no switch,
jumbo frames are on... maybe it's the e1000g driver? it's been wonky since 94
or so. even during the write bursts i'm only

ECC theory tells, that you need a minimum distance of 3
to correct one error in a codeword, ergo neither RAID-5 or RAID-6
are enough: you need RAID-2 (which nobody uses today).
What is RAID-2? Is it raidz2?

Hello all,
I am using 2008.11 with the Timeslider automatic snapshots, and using
it to automatically send snapshots to a remote host every 15 minutes.
Both sides are X4540's, with the remote filesystem mounted read-only
as I read earlier that would cause problems.
The snapshots send fine for
