That sounds similiar to Solaris's CacheFS, backing NFS to local disk for
faster access, and a little bit of stability (it can keep going with the NFS
server down)

No, what Solaris does is more like dumbed down Coda than network
RAID...

Speaking of, has anyone ever gotten Coda and it's associated
replication stuff to work under STABLE?

  Great (ly twisted) minds think alike, I guess.  We experimented with
this some here as a "skunkworks" (unofficial) project using various
combinations of Linux, FreeBSD, OpenBSD, and BSD/OS.  The problem is
that no combination we tried seemed to have a solid and stable enough
implementation of NFS and of vinum or "loopback FS" + raidframe, etc.
etc. to get it working reliably.  Let alone performing well.

  On the freebsd-current list, PHK is sounding pretty enthusiastic
about getting NBD implemented as an available block driver under GEOM.
That would be the "right place" to make it work with pretty much
everything disk-related in FreeBSD, I think.

Do you happen to know the name of the thread? I think some
encouragement about it would be in order. I'd definitely love this
feature (aside Java support, really the only advantage Linux has over
BSD these days if you ask me).

Best regards,
 Gabriel

   I would prefer iSCSI over NBD but still interested.  Will check it out.

   The Java port and Linux kernel module seem to work great.

Well iSCSI sure would be nice (it'd mean that you could use it with
basically every OS that supports it) but still, FreeBSD nbd
(preferably compatible to the Linux one but not really needed in my
case) would be a big step in the right direction...

Last time I tried (late december) jdk13 port wouldn't build for some
reason. It's PITA that it needs linux emulation in order to compile
anyway. Is there any chance that Sun will allow FreeBSD to supply a
native binary in the forseeable future?

   Hmm... I tried it a month ago or so and the latest (v1.4?) worked
perfectly.  Had Linux support and java command line executable running in
about 10 minutes.

P.S. please don't cc me

The jdk13 port should build fine, what was your particular problem?
As for your question, the answer is yes.
