It is a 4k sector drive, but I thought zfs recognised those drives and didn't
need any special configuration...?
4k drives are a big problem for ZFS, much has been posted/written
about it. Basically, if the 4k drives report 512 byte blocks, as they
almost all do, then ZFS does not detect

Hi all,
My system is powered by an Intel Core 2 Duo (E6600) with 8GB of RAM.
Running into some very heavy CPU usage.
First, a copy from one zpool to another (cp -aRv /oldtank/documents*
/tank/documents/*), both in the same system. Load averages are around
~4.8. I think I used lockstat correctly,

Quick update;
George has been very helpful, and there is progress with my zpool. I've got
partial read ability at this point, and some data is being copied off.
It was _way_ beyond my skillset to do anything.
Once we have things resolved to a better level, I'll post more details (with a

Or you could stick strictly to mirrors; 4 pools 2x2T, 2x2T, 2x750G,
2x1.5T. Mirrors are more flexible, give you more redundancy, and are
much easier to work with.
Easier to work with, yes, but a RAIDz2 will statistically be safer than a set
of mirrors, since in many cases, you loose a drive

My initial idea was to implement 100% reliable TRIM, so that I can

Yes, a full disclosure will be made once it's back to normal (hopefully that
event will happen).
The pool is mounted RO right now, and I can give some better stats; I had 10.3
TB of data in that pool, all a mix of dedup and compression.
Interesting enough, anything that wasn't being touched

Thank you for the solid answer.
It now looks like I am now seeking a 32 bit SAS card that I can put into
a Netra T1 or a V120.

The data below does not show heavy CPU usage. Do you have data that
does show heavy CPU usage? mpstat would be a good start.
