I decided to post this question to the mailing list because it needs ZFS
knowledge to be solved.
The situation is like this:
I have a blade server that boots from a LUN, which has no additional storage
or internal disk but that LUN used to boot.
MPxIO works perfectly; but the management wants
some light on this.
Regards,
Leandro.

Just in case someone of you want to jump in, I created the case
#100426-001820 to WD to ask for a firmware update to the WD??EARS drives
without any 512-byte emulation, just the 4K sectors directly exposed.
The WD forum thread:
Hello everyone,
As one of the steps of improving my ZFS home fileserver (snv_134) I wanted
to replace a 1TB disk with a newer one of the same vendor/model/size because
this new one has 64MB cache vs. 16MB in the previous one.
The removed disk will be use for backups, so I thought it's better off
Thanks Roy for your reply.
I actually waited a little more than an hour, but I'm still going to wait a
little longer following your suggestion and a little hunch of mine. I just
found out that this new WD10EARS is one of the new 4k disks. I believed that
only the 2TB models where 4k.

Confirmed then that the issue was with the WD10EARS.
I swapped it out with the old one and things look a lot better:
pool: datos
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait

Solved!
This what I did: boot with the disks unplugged, I took a 'digest -a md5
/etc/zfs/zpool.cache', then I did 'zpool export -f data', I got an error
message saying that the pool didn't exist. I checked again the MD5 against the
zpool.cache and it effectively changed (so, although the
No, Chris, I didn't export the pool becasue I didn't expect this to
happen. It's an excellent suggestion, so I'll try it when I get my
hands on the machine.
Thank you.

Hello to you all,
Here's the situation:
While doing a case replacement in my home storage server I accidentally removed
the post-it with the disk number from my three 1TB disks before connecting them
back to the corresponding SATA connector.
The issue now is that I don't know in which order
Thanks Tim for your answer!
I'll try it in afew hours and post the outcome.
