[OpenIndiana-discuss] Errors without errors

[Michelle]

Hi Folks,

About a month ago I updated my Hipster...
SunOS jaguar 5.11 illumos-ca706442e6 i86pc i386 i86pc

This morning it was absolutely crawling. Couldn't even connect via SSH
and had to bounce the box.

It was reporting a drive as faulted, but didn't give any numbers...
everything was 0. I'm now not sure what happened and whether the drive
is good, or whether I should roll back the OS.

(and the drive WD Red 6TB (not shingle) went out of warrantee a week
ago. How about that, eh?)

Grateful for any opinions please.
