I was brought an old FeeNAS appliance that would not boot... The USB boot media appears to be corrupted. So, I setup a new FreeNAS 11 installation. I moved the two drives (RAID1 mirror) over to the new appliance. I can see the drives... one has bad sectors and is listed as unreadable, but the remaining unit shows up and apparently has no errors. I'm including some basic information here... I would appreciate any assistance you guys/gals could offer to help me recover the still functioning portion of this mirror.
In the FreeNAS GUI... I can see both the good and failed disks in "View Disks", the "View Volumes" shows "no entry", and "Import Volume" shows no volumes to import.
The /dev/ada1 device seems to be fine... see below...
I'm a little confused about the gmirror vs zfs/zpool stuff that I've been reading in various searches... are these mutually exclusive or what?
Just a little background... I am basically a complete FreeNAS noob and most of my FreeBSD experience is limited to the FreeBSD underlying MacOS (OSX). I am pretty well versed in other linux distros (i.e. CentOS/Redhat & Ubuntu, but have always relied on hardware RAID solutions when using those distros... which again makes me a noob at the various software RAID options offered by any of the linux distros.
Thanks again, in advance, for any help you can provide.
