Hi,
I have seen a similar question on this list in the archive but
haven't seen the answer.
Can I avoid striping across top level vdevs ?
If I use a zpool which is one LUN from the SAN, and when it
becomes full I add a new LUN to it.
But I cannot guarantee that the

Is there a way to avoid it, or can we be sure that the problem does not exist
at all ?

No. The basic principle of the zpool is dynamic striping across vdevs in order
to ensure that all available spindles are contributing to the workload. If
you want/need more granular control over what data goes to which disk, then
you'll need to create multiple pools.
Just create a new pool
You have an application filesystem from one LUN. (vxfs is expensive, ufs/svm
is not really able to handle online filesystem increase. Thus we plan to use
zfs for application filesystems.)
What do you mean by not really?

Use growfs to grow UFS on the grown device.
I know its off-toopic

Grow the existing LUN rather than adding another one.
The only way to have ZFS not stripe is to not give it devices to stripe
over. So stick with simple mirrors ...
(I do not mirror, as the storage gives
Hello,
There is a feature of zfs (autoexpand, or zpool online -e ) that it can
consume the increased LUN immediately and increase the zpool size.
That would be a very useful ( vital ) feature in enterprise environment.
Though when I tried to use it, it did not work. LUN expanded and
Thank you for your replies.
First, sorry for misleading info. Patch 148098-03 indeed not included in
recommended set, but trying to download it shows that 147440-15 obsoletes it
and 147440-19 is included in latest recommended patch set.
Thus time solves the problem elsewhere.
Just for fun, my

imho, the 147440-21 does not list the bugs
