I know this is too late to help you now, but... Doesn't zpool status -v
do what you want?
Hi,
No indeed it does not. At the top it just says that resilvering is happening
and that's it. Let me guess... it's to do with the zfs version I'm using?

Hi,
I've got a 'resilver in progress'. Since resilvering is slowing my pool down
incredibly (db queries taking 20 times longer than normal), I want to pause
the resilvering.
AFAIK there is no way to tell resilvering to pause, so I want to detach the
inconsistent disk and attach it again
It depends: if you like to be able to restore single files, zfs send/recv
would
not be apropriate.
Why not?
With zfs you can easily view any file/dir from a snapshot (via the .zfs
dir). You can also copy that instance of the file into your running fs with
cp.

This means you can convert a non-redundant load-shared configuration into a
redundant

Bob,
Does that imply that when you add zfs automatically load-balances across its
mirrors?
Does that also mean that when the drives in a mirror are not as fast as each
other, the fs

Hi Richard,
The version on stable Solaris is v4 at best today. I definitely do not want
to go away from stable Solaris for my production environment, not least
because I want to continue my Solaris support contracts.
I will be attaching a Sun 2540FC array to these servers in the coming weeks
and

Actually, my ideal setup would be:
Shuttle XPC w/ 2x PCI-e x8 or x16 lanes
2x PCI-e eSATA cards (each with 4 eSATA port multiplier ports)
Mike, may I ask which eSATA controllers you used? I searched the Solaris HCL
and found very few listed there
Thanks

Indeed I want a permanent solution so I'll upgrade my zpool as suggested,
since that seems to be the only option
I searched sunsolve for the relevant patches /package downloads and googled
zfs upgrade but only got references to documentation. Any clues where I can
get the upgrade from?

For the record, I am told that I will need to wait for S10 u6 for zfs
delegation; can't upgrade before that.

Also, the -R option does not work on this zfs version,

When set up with multi-pathing to dual redundant controllers, is layering
zfs on top of the 6140 of any benefit? AFAIK this array does have internal
redundant paths up to the disk connection.

Addendum:
The fs was mounting on the wrong fs within the zone, and mounting a ufs fs
on the intended mount point.
To fix that, i zonecfged and removed the fs, and re-added it as a zfs
dataset.
Once done i changed the zfs mountpoint from within the zone
So:
zonecfg:anzan remove fs dir=/backup
# zoneadm list -cp
0:global:running:/
-:anzan:installed:/zones/anzan
That of any help?

Problem solved.
I did a zfs mount followed by a zfs unmount, and then the zone booted fine.
Thanks to William from the zones-discuss and Mark Musante, both from Sun.
The more i work with zfs, the more confidence i get in it.

Hi,
I have a zpool made of 2 vdev mirrors, with disks connected via USB hub.
While one vdev was resilvering at 22% (HD replacement), the original disk

on. The status of the disk came back to ONLINE, but there is

Thommy,
If I read correctly your post stated that the pools did not automount on
startup, not that they would go corrupt. It seems to me that Paulo is
actually experiencing a corrupt fs

Hi,
Is it possible to mirror a vdev within a zpool?
My aim is to replace a current raidz2 vdev with a mirror. I was wondering if
it is possible to create a mirrored vdev, use it to mirror my current vdev,
then when resilvering completes remove the old vdev

Hello,
I had a 3-disk raidz2 pool. I wanted to increase throughput and available
storage so I added in another 2 disks into the pool with:
zpool add -f external c12t0d0p0
zpool add -f external c13t0d0p0 (it wouldn't work without -f, and I believe
that's because the fs was online)

Hello,
I have a zfs pool on 3 external disks, connected via usb. All 3 disks are
fine and can be seen from rmformat. They all appear on the same nodes as

Any clues?
