hauntedunix's suggestion worked: mount the /var zpool as legacy. All hail!

The trick now is that the system won't install zones properly. The zone creates okay, verifies as installable, when I go to install it installs 3 packages and of course won't boot. This is because, desperate for space on Friday, I cleared all that faff out of /var/sadm/pkg ... which is where zone packages are installed from. D'oh!

So today I tried jumpstarting it. And IT appear to have set up the network so stuff won't tftpboot. ARGH. Tomorrow we make an appointment to go down to the server room and ... put the 10u8 SPARC DVD in the drive.

It's been a learning experience.

Oh, and the Solaris 10u8 i386 VirtualBox image that Sun heartily encourages everyone to download and try is a dysfunctional piece of complete dogshit that seems to have been put together with the express aim of warning people off Solaris.

I'm interested in your approaches to utterly hosing a CoW fs!

a. Fill several 1Tb volumes.
b. Delete it all at once.
c. Profit!

Actually, (c) expands to 'watch the Filer have a complete head-fit and peg the CPUs for several minutes. Since throughput has just fallen through the floor, watch all the businessy-businessy apps expire messily and then deal with the throng of angry suits between you and the coffee machine.'

The Netapp tech-note boils down to 'Don't do that. Performance can be sub-optimal.'

Yeah, most of the approaches to trashing ZFS are along similar lines: get it to tie itself in knots and use 75% system CPU trying to get itself sorted out. "With you in a moment ... a moment ... a moment ..." The famed killer ZFS block allocator bug (lots of small fast writes to a large zpool that's over 80% full, block allocator shits itself trying to allocate perfectly rather than well enough, box turns to molasses, requires reboot, workaround is to leave 25% of your huge expensive zpool empty) is one of these.
