An attempt to pkg image-update from snv111b to snv122 failed
miserably for a number of reasons which are probably out of
scope here. Suffice it to say that it ran out of disk space
after the third attempt.
Before starting, I was careful to make a baseline snapshot,
but rolling back to that
The limitations section of the Wikipedia article on ZFS currently includes
the statement:
You cannot mix vdev types in a zpool. For example, if you had a striped
ZFS pool consisting of disks on a SAN, you cannot add the local-disks as a
mirrored vdev.
As I understand it, this is simply
if you add a raidz group to a group of 3 mirrors, the entire pool slows
down to the speed of the raidz.
That's not true. Blocks are being randomly spread across all vdevs.
Unless all requests keep pulling blocks from the RAID-Z, the speed is a
mean of the performance of all vdevs.
-mg
yes, but it stripes across the vdevs, and when it needs to read data back,
it will absolutely be limited.

During reads the raidz will be the fastest vdev, during writes it
should have about the same write performance

Well, there is .zfs, of course, but it is normally hidden,
apparently by default on SPARC rpool, but not on X86 rpool
or non-rpool pools on either. Hmmm. I don't recollect setting
the snapdir property on any

while you technically CAN do it, it's a horrible idea.
I don't think it is necessarily as horrid as you say. Zfs does
distribute writes to
i don't think it's the same at all.
I think it's about the same as filling a radiator in a car with oatmeal to
make it stop leaking.

Near Success! After 5 (yes, five) attempts, managed to do
an update of snv111b to snv122, until it ran out of space
again. Looks like I need to get a bigger disk...
Sorry about the monolog, but there might be someone on this
list trying to use pkg on SPARC who, like me, has been
unable to

Correct. And the behaviour has been seen locally as well as remotely.
You are looking for I/O that takes
