I've been testing the ZFS root recovery using 10u6 and have come across a very
odd problem.
When following this procedure I the disk I am setting up my rpool on keeps
reverting to an EFI label.
http://docs.sun.com/app/docs/doc/819-5461/ghzur?l=en&a=view
Here is what the exact steps I am doing;
I've discovered the source of the problem.
zpool create -f -o failmode=continue -R /a -m legacy -o
cachefile=/etc/zfs/zpool.cache rpool c1t0d0
It seems a root pool must only be created on a slice. Therefore
zpool create -f -o failmode=continue -R /a -m legacy -o
cachefile=/etc/zfs/zpool.cache
Thanks I don't know how I missed it.

This morning we got a fault management message from one of our production
servers stating that a fault in one of our pools had been detected and fixed.
Looking into the error using fmdump gives:
fmdump -v -u 90ea244e-1ea9-4bd6-d2be-e4e7a021f006
TIME UUID
Thanks for this information.
We have a weekly scrub schedule, but I ran another just to be sure :-) It
completed with 0 errors.
Running fmdump -eV gives:
TIME CLASS
fmdump: /var/fm/fmd/errlog is empty
Dumping the faultlog (no -e) does give some output, but again there
ed rather than
there being a real issue with ZFS. Despite this, we're happy to know that we
can now match vdevs against physical devices using either the mdb trick or zdb.
We've followed Eric's work on ZFS device enumeration for the Fishwork project
with great interest - hopefully
We have a number of Sun J4200 SAS JBOD arrays which we have multipathed using
Sun's MPxIO facility. While this is great for reliability, it results in the
/dev/dsk device IDs changing from cXtYd0 to something virtually unreadable like
"c4t5000C5000B21AC63d0s3".
Since the entries in /dev/{rdsk,d
mdump doesn't produce any "human readable" disk ids, only
guids which then have to be correlated via a "zdb -c"

devfsadm -C alone didn't make a difference, but clearing out /dev/*dsk
and running devfsadm -Cv did help.
I am glad it helped; but removing anything from /dev/*dsk is a kludge

ZFS is a 128 bit file system. The performance on your 32-bit CPU will
not be that good. ZFS was designed for a 64-bit CPU. Another GB of RAM
might help. There are a bunch of post in the archive about 32-bit CPUs

ZFS will stripe across all Root Level VDEVs, regardless of type of VDEV
(mirror, raidz, single whole disk, disk slices, whatever).
e.g.
