My Helios froze today, no contact with SSH nor USB serial console. Blue heartbeat was off and red led was on, can't remember if it pulsed/blinked... Had to reboot. Now my system has been resilvering since (3 disk zfs mirror pool) with 2 of the disks being resilvered. I'll copy zfs status output here:
root@helios64:~# zpool status
pool: export
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

Those 2 disks that are resilvering are new disks, the last one is older.
Do we have a solution of some sort? I've just requested the HDD wires via email...
