Pool name : volume1

As said, there was a power failure, system got stuck on restart.

Following error message :
---------------------------------------------
"Solaris Notice cannot find the pool label for boot -pool
mounting from zfs:boot-pool/ROOT/default failed with error 5"

And then message followed by command line :
"mountroot>"
(N.B. after some time, not sure exactly how, it later changes to 'db>' after displaying "unblockind device")
---------------------------------------------
I tried doing a fresh install on a USB key : same message.
Tried booting with this USB key (fresh install) and no HDDs connected : same message
Tried booting with this USB key (fresh install) by launching with following parameters : kernel debug + verbose + safe mode. I can access the webgui, can import pools and see disks and data are ok. But when I restart, I still get the same message, aka can not start normally.

Tried booting with SSD original install and no HDDs connected : same error message


[Update 1] Was confused by having SSD and USB key both refusing to boot with same error. After several tests, it appears the problem is clearly hardware and the USB probably has compatibility issues. Long story short, most certainly SSD related. Will reinstall on a new one (and mirror it to avoid same problem in the future).

[Update 2] Reinstall on new SSD : works again.
