The "it" was the subject of the previous sentence, which you diked out; that's how prepositional phrases work in English. 8-). In other words, multiple access to the same device from one or more SCSI controllers. > > SAN and NAS are also options, but of course, you still have to have > > an FS that can deal with it, and an external locking protocol. > > Right, we were talking about FreeBSD, which lacks such a filesystem :( I've said it before, and I'll say it again: porting GFS would be a really trivial amount of work, taking almost no creativity to do; the last time this subject came up and Sistina was offering to change their license, I ported all the user space utilities in under a day. I didn't finish off the whole FS port because I lacked the necessary disk drives and FreeBSD lacked the necessary controller driver for those disk drives, and the active maintainers claimed that they had a port in progress. These types of things are primarily busy-work and a way to spend money on hardware I'll likely never use in a production environment to end up with code under a license that prevents me from using it in a commercial product. That makes doing the work very uninteresting. -- Terry
