Your point is also valid. However, our experience with ZFS on the boxes that we have installed it has been nothing but positive since about 7.2, and Steve Bertrand has also posted that his experiences have been nothing but positive. I know that ZFS on FreeBSD hasn't gotten a "stable" rating yet, but it appears to be approaching that level and I don't think putting it in the installer (and perhaps marking it as "beta") so that more people could test it and give feedback about bugs and their experiences would be a bad thing. To be clear, ZFS itself is indeed stable - our Solaris file servers are running it in multi-terabyte configurations on servers that get pounded to the order of nearly saturating a 1GB LAN link. ZFS is the only file system in our experience that has suffered no data losses in arrays with more than one terabyte (knock on wood). All other file systems have failed disastrously for us in multi-terabyte configurations. So what you're talking about is not the stability of ZFS itself, but the port of ZFS on FreeBSD. > Does this paint a better picture to you of what I forgot to > clarify in my original posting? Yes, clarity is key. Thanks! :) Tim Gustafson Baskin School of Engineering UC Santa Cruz tjg@soe.ucsc.edu 831-459-5354
