In this case I suggest you _do_ figure it out because this is part of the extra admin overhead you said you didn't mind. Instead of CTRL-A-C you can simply use F1/F2 to switch between an extra shell to run format and the installer window.


Yeah, well "simply" is another strange issue. Solaris device naming is
making my head spin.  c0t0d0p0?

I'd still like to know why the specific arrangement I'm contemplating is not recommended. Other than the admin cost, of course, which I've already
been paying 10x over with Linux/mdRAID1/mdRAID5/mdRAID6 and ZFS-Fuse!

David,

Welcome to the world of Solaris. It's a love/hate relationship.

Where's the love?

think: controller 0 target 0 disk 0 partition 0.

partitions != slices

in this case (Solaris x86), slices are actually contained on a partition of type solaris2. Only one solaris2 partition will be recognized per disk so don't bother making multiple solaris2 partitions. You'll need two slices per disk to place your two pools on.

To modify slices, man format.
To modify partitions, man fdisk.


Status: Nexenta will install on my external USB disk or an internal SATA disk, but won't boot. OpenSolaris will install on a USB 2.0 memory stick... from which I can't boot my machine, for some reason. The installer won't recognize my external USB disk as an installation target, so I can't install it there. I managed to install OpenSolaris to an internal disk, but have been unable to identify the USB disk for use in a zpool, so I don't know how to transfer the root slice there. The disk is indeed detected acording to /var/adm/messages and the appearance of /dev/usb/mass-storage0, but there appears to be nothing in /dev/[r]dsk that applies (of course, even with your hint above, it's hard to know for sure).

Oh, yeah: ssh'ing into the OpenSolaris machine takes forever and none of my Linux tricks for that issue work, to boot.

Unless you have some magic incantations for me, I guess I'm about to give up and go back to linux/ZFS-Fuse.
