Is securelevel, or zpool keeping me from running smartctl ?

[Jason Usher]

I have a system with a running zpool, and also securelevel=2.

When I run:

smartctl -a /dev/da0

I get:

/dev/da0: Operation not permitted
Smartctl: please specify device type with the -d option.

On another system, this works just fine - the disk is not being used in a zpool, AND securelevel is not enabled.

So ... am I getting this error because /dev/da0 is part of a zpool, or am I getting this error because I have securelevel=2 ?

Thanks.
