Tamarack, Gnome 2.17 and external devices

This is a combination that I've been hanging on. vold never quite handled my cds, dvds and usb media quite right.
I'm happy to say that for the most part it all just works like it should.
Well, I have a multi-partitioned usb device which exhibits an interesting problem.
First, let's have a look at how the device (it's a 60gb usb 2 disk) is partitioned.
Total disk size is 57231 cylinders Cylinder size is 2048 (512 byte) blocks Cylinders Partition Status Type Start End Length % ========= ====== ============ ===== === ====== === 1 Ext Win95 1 28615 28615 50 2 Solaris2 28616 57230 28615 50 Partition 1 has a fat-32 filesystem. Partition 2 has an SMI label and slice 0 is a zfs pool with the imaginitve name 'usb'. # fstyp /dev/dsk/c4t0d0p1 pcfs # fstyp /dev/dsk/c4t0d0s0 zfs
If I insert this disk into my notebook running b53, I get the notice about not being able to mount the zfs pool (which I expect), but it does not notice the fat-32 partition, let alone mount it:
# rmmount -l /dev/dsk/c4t0d0s0 rmdisk,rmdisk0,usb
I had a chat with one one of the developers about this. He found that if we place the zfs pool directly into the second partition, then everything works as you would expect. The different controller numbers and zfs pool name are purely due to using another disk and machine in anotehr continent.
# fstyp /dev/dsk/c2t0d0p1 pcfs # fstyp /dev/dsk/c2t0d0p2 zfs # rmmount -l /dev/dsk/c2t0d0p0:1 rmdisk,rmdisk0,NONAME,/media/NONAME /dev/dsk/c2t0d0s2 rmdisk,rmdisk0,lacie_p2
It turns out that if hal discovers an SMI label on any partition, it does not probe any of the other logical disks, leading to the logging of
In the meantime as I really don't want to muck around with the existing zpool, I'll continue to mount my pcfs manually, but it will be nice when this one is fixed.
It's probably also worth mentioning that "zpool import usb" just works.
