For the record, I was able to get this same panic when I dd'd /dev/zero over a
file that was part of my own test pool. Specifically, I had files of sizes 128M
192M 192M 256M in a simple pool with copies=2. I put a 109M file on the
filesystem and ran 'dd count=1 bs=192M if=/dev/zero of=disk2'. Th

I have had some success using zfs send recv into a child of a
compressed filesystem to do this although you have the disadvantage
of losing your settings.
basically :
zfs create tank/foo
mv a bunch of files into foo
zfs create tank/bar
zfs set compression=on bar

We are looking at the alternatives to VXVM/VXFS. One of the feature which we
liked in Veritas, apart from the obvious ones is the ability to call the disks
by name and group them in to a disk group.
Especially in SAN based environment where the disks may be shared by multiple
machines, it is ve
If you are doing things manually, you could as well unmount the ufs partition
and mount a zfs dataset to the same location just before the installer starts
installing the packages? Saves some file copying and you could remove the ufs
partition entirely?

It would be slow, and the file system would need to be idle to avoid
race conditions, and it wouldn't be very fast, but you _could_ do the

Hi,
This is a report of my latest investigations on how to setup (by hand) your ZFS
root filesystem.
My experiment was carried on with Solaris Express Community Edition b66 DVD and
an additional disk slice to temporarily install the root fs to. It takes place
