Dtrace iosnoop does not work on LDOM Solaris 11 ZFS

Hi,

 

On Solaris 10 with ufs, I used an iosnoop script (downloaded from http://www.brendangregg.com/DTrace/iosnoop) which worked well.

 

The output was :

 

iosnoop -veoD -N -n procSRV

On a Solaris 11 LDOM with ZFS, for the same application, I have the following output :

Zhe pathname is always none and there are only Read IO.

 

Why does it not work in S11 ZFS LDM environment ?


Thanks.
