Hey,
I did a similar test a couple of months ago, albeit on a smaller system,
and 'only' 10,000 users. I saw a similar delay at boot time, but also
saw a large amount of memory utilisation.
I didn't notice the major memory usage, but the box had no other use,
than to mount these mass of empty

I was trying to import the pool, but got an error that there
wee 2 pools with the same name (in exported state) and I had
to import by "id". Thus I wanted to destroy the other pool

I've created non global zones with ZFS underneath the root filesystem

Neel,
Is it possible to destroy a pool by ID? I created two pools with the
same name, and want to destroy one of them
Could you please cut and paste (ie. not re-type) the output from the command "zpool
list | col -b", and post it here please?
Thanks... Sean.

How do you manage to do that? This should be impossible, and is a bug
in ZFS somewhere. The internal AVL tree is

Sounds good to me. I'd make sure it's in the same section of the BP

Hi,
*sigh*, one of the issues we recognized, when we introduced the new
cheap/fast file system creation, was that this new model would stress
the scalability (or lack thereof) of other parts of the operating
system. This is a prime example. I think the notion of an automount

I'd really like to see this feature. You say ZFS should change our view
