>From what I have heard:
* Linux does not implement NFS writes correctly in that data is not
flushed to disk before returning. Don't turn your Linux system off
during application writes since user data will likely be lost when
the system returns. Besides the applications losing data, running
applications are likely to become confused.
* ZFS has had an issue in that requesting a fsync() of one file
causes a sync of the entire filesystem. This is a huge performance
glitch. Wikipedia says that it is fixed in Solaris Nevada.
Someone should update this WikiPedia section:
