OpenZFS on OS X

One disk in 4-disk pool suddenly showing UUID in 10.10.5

MacPro:~ roberthancock$ zpool status -v NEWBOOM
pool: NEWBOOM

Any ideas why?
Any remedial action needed before TSHTF?

no reason to panic. InvariantDisk replaces disk name with serial, which is better for all and how it should be. A better question is, why do you have disk0, disk4 and disk6 naked, and not as serial

I have always to use -t 16000 for Invariant Disk for the /var/disk/by-id to work, have an Areca SAS Controller.

Otherwise the pool gets imported to early by using the blockdevice names on startup

You've got me there! I just set it up following the instructions in Absolute Beginners a few months also and that is how it has always been without the UUID on one disk. I don' t know what "naked" means (in this context).
Is there a terminal command I can run to "clothe" disks 0, 4 and 6?

This seemed the best place to post some behavior I've seen. I upgraded from 1.3 to 1.4.5.

I am now seeing this:

disk1 ONLINE 0 0 0

Before the upgrade, I only saw disk names and now I'm seeing seeing the serial ID on two disks in different pools.
zdrive is internal, zaux and zarchive are in an external enclosure.

Odd behaviour so I thought I'd mention it hear.

Just a startup race. Export and reimport.

Tried doing an export/import and things didn't change. Did an export and a reboot and got this as a result:

zaux went back to 2 disk*s, zarchive stayed the same, and zdrive went to 2 serial IDs.

Not quite sure what I'm supposed to be seeing, but I don't think that this is what is expected.

Did you import -d /var/disk/by-id?

No. The only thing that changed was the upgrade from 1.3 to 1.4.5. Now (after a couple of reboots) all disks in the external enclosure have disks names and the internals are both have serial IDs.

Im suggesting that you need to export/import as specified above.
