ZFS

This is a response to Jesper's blog post about ZFS.

ZFS looks very attractive to me as well, but I still haven't tried it. Some of the concepts, such as snapshots are old, but some are more original. It's interesting to read the Linux peoples response, saying basically that "we can do all that already". This might almost be true, but misses one point. Sun has made ZFS do everything in one nice packags. They have put a lot of thought into things like the command-line interface that makes it possible to actually use the advanced features. At least that's my impression, but I still haven't used it.

One thing I have used is Linux and ext3 over LVM. It works, but it seems like too much headache even for something as simple as growing the size of a filesystem/partition. You can't say that you want to grow this filesystem, instead you first have to grow the logical volume, and then resize the filesystem. Unless you are shrinking it,
