Hello,
Solaris 10 GA + latest recommended patches:
while runing dtrace:
bash-3.00# dtrace -n 'io:::start [EMAIL PROTECTED], args[2]->fi_pathname] = count();}'
...
oracle <none> 2096052
How can I interpret '<none>' ? Is it possible to get full path (like in vim) ?
Section "27.2.3 fileinfo_t" of DTrace Guide explains in detail why you see '<none>' in many cases.

The "execname" part can also be misleading, as many I/O activities are "asynchronous" (including but not limited to Asynchronous I/O), so whatever thread running on CPU may have nothing to do with the I/O that's occuring.
This is working as designed and not a "problem" that limited to ZFS, IMO.
