That's not quite the way I learned it, but I won't argue (too much) - except with the 'always' word. <g>

This is heading in the same direction I was heading - the current SAN/NAS protocols tend to be safe, whereas pure NFS has been known to cause 'write-confirmation' issues on occasion.

In addition, I note there are different versions of Solaris. I have no idea whether the filesystem [drivers] are identical.

No matter which way I look, this points at a filesystem issue, not an Oracle issue. I'd need to eliminate that first before pointing back at Oracle.
