Thanks. For now my sudo wrapper works, but I would be very happy if this

Thanks for your observations.

Hello,
I'm trying to track down a problem with taking zfs snapshots. On
occasion the zfs command will report:
cannot snapshot 'dataset name': dataset is busy
The problem is, I don't know what causes zfs to think the data set is
busy. Anyone out there know what constitutes a busy dataset?

Hi,
We have a number of 4200's setup using a combination of an SVM 4 way mirror and
a ZFS raidz stripe.
Each disk (of 4) is divided up like this
/ 6GB UFS s0
Swap 8GB s1
/var 6GB UFS s3
Metadb 50MB UFS s4
/data 48GB ZFS s5
For SVM we do a 4 way mirror on /,swap, and /var
So we have 3 SVM
mirror2 / # zpool history
History for 'tank':

c2t1d0 c2t2d0 c3t0d0 c3t1d0 c3t2d0 c3t3d0

Jonathan,
Thanks for providing the zpool history output. :-)
You probably missed the message after this command:
# zpool add tank c4t0d0
invalid vdev specification
use '-f' to override the following errors:
mismatched replication level: pool uses raidz and new vdev is disk
I provided some
Can someone point me to a whitepaper, blog, or other document that

Have you read the ZFS On-Disk Specification??

Or are you trying to find something specific??

Hi,
I have a system that had Solaris 10 8/07 previously installed with disks c0t0d0
and c0t1d0 mirrored using SVM and c0t2d0 and c0t3d0 added as whole disks to a
zpool.
When attempting to reinstall the OS via jumpstart the following error is output:

Using rules.ok from jumpstart:/js.
My guess is that you're looking for the on-disk format document:
http://www.opensolaris.org/os/community/zfs/docs/ondiskformat0822.pdf
If you're more interested in the user-visible metadata (e.g. the settings for
pools and filesystems), then you'd probably have to dig through the various

2007-12-03.14:42:28 zpool add tank c4t0d0
c4t0d0 is not part of raidz2. How can I fix this?
Back up your data; destroy the pool; and re-create it.
Ideally I would like to create another zpool with c4t0d0 plus some more disks
since

I think this is just the ARC; you can limit its size using:
