G'day,
I have an OI server from ~2 years or so ago that went down overnight
- it has 5 HDDs, 2 as a ZFS mirror (root) and 3 as a ZFS raidz
array. I can see all 5 drives when I boot off an OI USB boot image,
but I can't see anything more than the output from format, which sees
that all 5 exist.
zfs list etc don't show me anything
Is there a way to try and mount these drives onto the USB boot image
and inspect them? Maybe I have a corrupted boot block or something?
As per another email, I think this ended up being a dying power supply
not providing enough grunt to spin up 5 drives in time.

Good Morning!
Glad you have your system running again!
As you might know in the meantime, these are hints for working with a
non-starting system:
zpool import shows all your pools on a boot with an USB image
zpool import rpool
beadm list
beadm mount ......
bootadm install-bootloader -M -f -P rpool
It is always a good idea to be prepared for such 'events' and have a
booklet with hints and maybe tried out some bad scenarios with a vm...
i am not prepared :-/
Greetings,
Stephan
