The only thing I haven't found in zfs yet, is metadata etc info.
The previous 'next best thing' in FS was of course ReiserFS (4). Reiser3
was quite a nice thing, fast, journaled and all that, but Reiser4
promised to bring all those things that we see emerging now, like cross
FS search, any document, audio recording etc could be instantly
searched. True there is google desktop search, trackerd and what not,
but those are 'afterthoughts', not supported by the underlying FS.
You could use extended attributes for this type of data - just like HFS+
does - and then build a search tool ontop of that (like what MacOS X
does with Spotlight).
You can store any kind of data you like in an extended attribute,
however I would caution you that storing the metadata of somethink like
an MP3 file in metadata may not actually be quicker in the long run.
Exactly what problem are you trying to solve and what kind of metadata
are you looking for that isn't natively inside the file formats like MP3
for track info and EXIF data in JPEG etc ?
Why do you believe that the file system having knowledge of this is
better some how ?
The other thing that ZFS has is user defineable properties on each dataset.
