Hi,
the question is which WD Green drives you are using. WDxxEADS or WDxxEARS. The
WDxxEARS have a 4k physical sector size instead of 512B. You need some special
trickery to get the max performance out of them, probably even more so in a
raidz configuration.

I think both have native 4K sectors; as such, they balk or perform slowly
when a smaller I/O or an unaligned IOP hits them.
How are they formatted? Specifically, solaris slices must be al

Hi Ketan,
My flash archive experience is minimal, but..
This error suggest that the disk components of this pool might have some
SVM remnants. Is that possible? I would check with the metastat command,
review /etc/vfstab, or /etc/lu/ICF.* to see if they are referencing
meta devices.
Thanks,

Ketan,
Someone with more flash archive experience that me says that you
can't install a ZFS root flash archive with live upgrade at this
time. Duh, I knew that.
Sorry for the red herring... :-)

The described problems with WD aren't okay for non-critical

I'm sorry to say that I am quite the newbie to ZFS. When you say zfs
send/receive what exactly are you referring to?
I had the zfs array mounted to a specific location in my file system

The only tweak needed was making sure that I used the FQDN of the client

Brilliant. I set those parameters via /etc/system, rebooted, and the pool
imported with just the f switch. I had seen this as an option earlier,
although not that thread, but was not sure it applied to my case.
Scrub is running now. Thank you very much!

Thanks a lot for that. I'm not experienced in reading the output of dtrace,

IIRC the currently available WD Caviar Black models no longer enable TLER to be
set. For WD drives, to have TLER capability you will need to buy their
enterprise models like REx models which cost mucho $$$.
