Just thought I would let you all know that I followed what Alex suggested along
with what many of you pointed out and it worked! Here are the steps I followed:
1. Break root drive mirror
2. zpool export filesystem
3. run the command to start MPIOX and reboot the machine
4. zpool import
I'm just wondering what some of you might do with your systems.
We have an EMC Clariion unit that I connect several sun machines to. I allow
the EMC to do it's hardware raid5 for several luns and then I stripe them
together. I considered using raidz and just configuring the EMC as a JBOD,

I've been playing around with zones on NFS a bit and have run into
what looks to be a pretty bad snag - ZFS keeps seeing read and/or
checksum errors. This exists with S10u8 and OpenSolaris dev build

If I disable compression and enable dedup, does it count deduplicated
blocks of zeros toward the dedupratio?

Alex, thanks for the info. You made my heart stop a little when reading your
problem with PowerPath, but MPxIO seems like it might be a good option for me.
I'll will try that as well although I have not used it before. Thank you!

I had a system that I was testing zfs on using EMC Luns to create a striped
zpool without using the multi-pathing software PowerPath. Of coarse a storage
emergency came up so I lent this storage out for temp storage and we're still
using. I'd like to add PowerPath to take advanage of the
Thanks Cindys for your input... I love your fear example too, but lucky for me
I have 10 years before I have to worry about that and hopefully we'll all be in

It looks like I'm going to have to create another test system and try

able to remove a vdev from a pool anytime soon?
Thanks!
