Just a quick note about mounting ZFS resource in a non-global zone...

This is in response to a question that was posted in the SUN Solaris Experts group on LinkedIn:

I keep running into people who think that you have to reboot a non-global zone to add a ZFS mountpoint. Not true.

After you add the zfs resource to your zone.xml (use zonecfg, if you follow recomendation, heh) you perform the following on the Global Zone (not within the non-global zone). Be sure to define the type as "legacy":

root@global-zone# mount -F zfs your_zpool/your_filesystem_name /zones/non_global_zonename/root/your_mountpoint

Log into your zone and you should now see the new filesystem (DF or whatever).

ZFS Deduplication Is In!

If you've been waiting (as I have) for Dedup capability in ZFS, then the wait is close to over. See Jeff Bonwick's blog: http://blogs.sun.com/bonwick/en_US/entry/zfs_dedup

I can't wait to test it, as soon as I can find out how to get my hands on it, lol. It's not in Sol10 update 8, nor is it in the most recent snapshot of OpenSolaris, but I suspect it will be out soon.

Edit:

Seems my rss feed is slow. It's currently in OpenSolaris, as of last night!

Solaris 10: Enable SMCwebserver For Easy ZFS Management.

You know, sometimes a GUI is nice to have around. I'm not "really" a "GUI Fanboy" when it comes to system management and administration, but there are those times when it's just easier to see things, presented in way that's easy to access and not have to run a handful of commands and scroll through a ton of output, etc.

A lot of you are probably already aware of the SMCwebserver http interface and are still trying to remove the bad taste from your mouths, from the Oct 08 release of Sol 10 that totally fraked the whole thing up. I am happy to report that, thus far, it seems it's working again, in the May 09 release (5/09 s10s_u7wos_08 release). Now lets see if a subsequent cluster patch breaks it again, rofl.

I digress...

So, for those who are un-aware of how to enable the service to accept connections, remotely, here's a quick and dirty:

/usr/sbin/svccfg -s svc:/system/webconsole setprop options/tcp_listen = true

/usr/sbin/svcadm refresh svc:/system/webconsole

/usr/sbin/smcwebserver stop

/usr/sbin/smcwebserver start

/usr/sbin/svcadm enable svc:/system/webconsole

That should do it. Now make sure your port (6789) is listening to "All" (*):
/usr/bin/netstat -an|grep 6789

*.6789 *.* 0 0 49152 0 LISTEN

Now open your web browser on your desktop machine (laptop, whatever) and go to the server:6789

(http://your.server.address:6789)

Go through all of the security exception notifications and log in with the account with proper credentials (like root, for example, though I suggest you set up another account, instead).

Have fun with it and here's the smcwebserver manpage: http://docs.sun.com/app/docs/doc/816-5166/smcwebserver-1m?a=view
