If your entire pool consisted of a single mirror of two disks, A and B,
and you detached B at some point in the past, you *should* be able to
recover the pool as it existed when you detached B. However, I just
tried that experiment on a test pool and it didn't work. I will
investigate further
Hi Dominic,
I've built a home fileserver using ZFS and I'd be happy to help. I've written
up my experiences, from the search for suitable devices thru researching
compatible hardware, and finally configuring it to share files.
I also build a second box for backups, again using ZFS, and used
Jeff thank you very much for taking time to look at this.
My entire pool consisted of a single mirror of two slices on different disks A
and B. I attach a third slice on disk C and wait for resilver and then detach
it. Now disks A and B burned and I have only disk C at hand.

Urgh. This is going to be harder than I thought -- not impossible,
just hard.
When we detach a disk from a mirror, we write a new label to indicate
that the disk is no longer in use. As a side effect, this zeroes out
all the old uberblocks. That's the bad news -- you have no uberblocks.

Hello zfs-discuss,

If I attach a disk to vdev in a pool to get mirrored configuration
then during resilver zpool iostat 1 will report only reads being
done from pool and basically no writes. If I do zpool iostat -v 1
then I can see it is writing to new device
If I understand you correctly the steps to follow are:
read each sector (dd bs=512 count=1 split=n is enough?)
decompress it (any tools implementing the algo lzjb?)
size = 1024?
structure might be objset_phys_t?

Hi,
ZFS won't boot on my machine.
I discovered, that the lu manpages are there, but not
the new binaries.
So I tried to set up ZFS boot manually:
zpool create -f Root c0t1d0s0
lucreate -n nv88_zfs -A nv88 finally on ZFS -c nv88_ufs -p Root -x /zones
zpool set bootfs=Root/nv88_zfs

Hey, hi Rick!
The obvious thing that is wrong is the network being recognised as 100Mbps and
not 1000. Hopefully, the read/write speeds will fix themselves once the network
problem is fixed.
As it's the same cable you had working previously at 1000Mbps on your other

Rick,
Glad it worked ;-)
Now if I were you, I would not upgrade the BIOS unless you really want/need to.
I look forward to seeing your revised speed test data for reads and writes with
the gigabit network speed working correctly. I think it should make a little
difference -- I'm guessing
Folks,
How can I find out zpool id without using zpool import? zpool list
and zpool status does not have option as of Solaris 10U5.. Any back door
to grab this property will be helpful.

This is present as the 'guid' property in Solaris Nevada. If you're on
a previous release, you can do one of the following:
- 'zdb -l device in pool' and look for the 'pool_guid' property (if
you're using whole disks you'll still need the s0 slice).
- '::walk spa | ::print spa_t spa_name

I have a problem on one of my systems with zfs. I used to have zpool created

When I do try to import it it does fail. I am using EMC
