If the import fails, you can always put the 9.0 drives back in and get back up
and running fairly quickly.
My system has the OS on a mirror zpool of two drives for just t

when migrating large amounts of data, which thankfully does not happen all that
often.

But this is a statistical probability, and some drives will have more

although I don't know if the distribution falls on a typical gaussian (bell)

Has anyone else run into this problem and what was the fix (or did you
just install into /usr/local) ?
erms of root FS or in terms of boot loader ?
The boot loader would be set in your BIOS (which physical drive you read for
that).
/ comes from the zpool/zfs dataset once the boot loader loads enough code
to find and mount the filesystem. That comes from all the drives in the zpool.

Unfortunately, my external exclosure has a SATA port expander as I need to talk
to 4 external drives. That gives me about a factor of 2 worse performance than
the internal SATA drives (even if I am only talking to one drive via the
external connection).

Note that if you do NOT mirror SWAP, then in the event of a disk
failure you will most likely crash when the system tries to swap in some data
from the failed drive. If you mirror swap then you do not risk a crash due to

efinition, be children of the rootpool) you will end up with

to take place in very specific order (such as mounting and un mounting). By
avoiding hierarchical datasets (that are actually used) you avoid that
complexity.

When you give ZFS the whole disk, it writes an EFI-like label on the
drive and makes us of one partition for the ZFS data. So there *is* a form of
partitioning at the lower most layer, it is just *not* user managed
partitioning.
