Assertion raised during zfs share?
Posted:

Working to get ZFS to run on a minimal Solaris 10 U2 configuration. In
this scenario, ZFS is included the miniroot which is booted into RAM.
When trying to share one of the filesystems, an assertion is raised -
see below. If the version of source on OpenSolaris.org matches
Solaris 10 U2, then it looks like it's associated with a popen of
/usr/sbin/share. Can anyone shed any light on this?
Thanks,

This indicates that share(1M) didn't produce any output, but returned
a non-zero exit status. I'm not sure why this would happen - can you
run the following by hand?
# share /export
# echo $?
Incidentally, the explicit 'zfs share' isn't needed, as we automatically
share the filesystem when the options are set (which did succeed).

BTW, on my system running the latest bits this correctly shows:
# zfs share test
cannot share 'test': filesystem already shared
Which is what I would expect in your case as well.

Looks like the NFS server is not completely configured yet, and that it
requires this zfs share stuff to work first.
bash-3.00# svcs -a | grep nfs/server

What does "minimal" mean? Most likely, you are missing something.

Yeah. Looking at package and SMF dependencies plus a whole lot of and
trial and error, I've currently got Solaris down to 47 packages. The
nfs/server service for Solaris 10 U2 will first try to do a zfs share.
For the next step, I'll probably comment out that stuff and see I can
bring up the nfs server code and share a UFS filesystem using the
traditional methods. Once that's OK I'll move on to the ZFS portion and
investigate.
Thanks,
-- Jim C

Out of curiosity, why are you trying to do this?

A very valid question, I work in Sun's OEM Software organization, and
for the first time we are seeing real opportunities for Solaris as an
embedded OS for appliances. Countless Linux devices boot from flash in
a matter of seconds and just work. Why can't Solaris do the same
thing? We are being asked by our PC OEMs for ideas as to how Solaris
might fit in this market. This is admittedly an exercise; we need to
become more knowledgeable about embedding Solaris and I was looking for
an application that is currently unique to Solaris, and thought I'd
take a crack at creating a "poor man's thumper". So currently:
o I've got a modified Solaris miniroot with ZFS functionality which
takes up about 60 MB (The compressed image, which GRUB uses, is less
than 30MB). Solaris boots entirely into RAM. From poweron to full
functionality, it takes about 45 seconds to boot on a very modest 1GHz
Cyrix Mini ITX motherboard.
o As Solaris runs entirely in RAM, there is no Solaris footprint on the
attached storage. It is entirely dedicated to ZFS. With a little
kludgery, all state can be managed from ZFS in effect making Solaris
stateless. There should be no serious ramifications to pulling the plug
on this device. In fact that's pretty much how this thing is rebooted
right now.
o As a potential example, one might consider managing this device via a
web-based interface, perhaps not all that different than the way you
might manage say, a Linksys router.
Yeah I know this is silly, but it's fun. Time to get back to my real job

That's great, keep up the good work!!

This is already one of the reasons I love Solaris so much, with UFS
logging I can pull the plug on my U1 firewall and never have to worry
about it getting screwed up, this just takes that a step further.

Not at all silly. Solaris is a fantastic OS, and this would just be yet
another great application for it's greatness to shine. ;)
*I* would definitely use it this way, no doubt about it.

Silly is the opposite of such a project! I'm just wondering how so much time has passed without it becoming an explicit OpenSolaris project!
A RAM-driven headless ZFS file server to compete with FreeNAS, OpenFiler, Windows Storage Server 2003 and Windows Home Server? Where do we sign up for this?!?! :)

If I had had that a few months ago, I might have designed a completely different system. Great job! Malachi On 3/27/07, MC <

Hi Jim,
that's absolutely great, respect.
Where is it possible to get more infos about what you have done so far?
to rebuild that for a own try?
cheers
