Greetings All,
I can't believe it didn't figure this out sooner. First of all, a big thank
you to everyone who gave me advice and suggestions, especially Richard. The
problem was with the -d switch. When importing a pool if you specify -d and
a path it ONLY looks there. So if I run:

Hi Ryan,
What events lead up to this situation? I've seen a similar problem when
a system upgrade caused the controller numbers of the spares to change.
In that case, the workaround was to export the pool, correct the spare
device names, and import the pool. I'm not sure if this workaround

That is not for sure at all, it all depends on what "the right thing"

Both of them support AHCI, so they should work for SATA 6G. The USB3.0

You want the write cache enabled, for sure, with ZFS. ZFS will do the
right thing about ensuring write cache is flushed when needed.
For the case of a single JBOD, I don't find it surprising that UFS beats
ZFS. ZFS is designed for more complex configurations, and provides much
better data integr
