I am still working on the new system build as outlined here. Thought I was getting to the point of being able to put this in production and get it in use and was attempting to add my new CZ33 Sandisk Drives and remove the old Generic USB stick that I had used for testing when the 32GB Ultra Fits would not work in this board. I inserted the first new USB device and successfully added it to the boot-mirror. This resilver'd just fine and I shut down the system and restarted it and everything appears to be just wonderful.
I then attempted to add the second CZ33 and do a replace from Web UI of the old generic USB to the second CZ33. This was running last night when I went to bed. I woke up this morning, and it appeared that the resilver failed after about 28 minutes with to many fatal errors. (Checked with zpool status -v). This struck me as odd as I scanned both these New CZ33 Drives with Rufus for bad blocks for 4 passes before attempting to put them in production and saw no errors. At this point the system was still running but I could not view the boot status in the web ui. It was throwing an error but at this time I cannot remember what it said and I cannot get back to that point at this time. So I restarted the system, because the UI was still reporting the pools as healthy. Just the Replacement had failed. At this point is where I ran into my issue. On reboot grub throws an error at me that says this.
This is not critical for me at this point, but I want to use this as a learning experience. Is there a way to recover from this? When I do an ls at this prompt It lists all the drives, but when I do an ls (hd0,1) or anything like that on any of the list - I just receive '(hd2): Filesystem is unknown.
I put my FreeNAS installation USB drive back into the machine and prompted the installer to use the old generic USB Drive as the installation destination, and the Installer Detected that there was already a FreeNAS System present and asked me to upgrade or fresh install, so the system appears to still be there, but GRUB is borked, and I will be first to admit that I am not overly familiar with GRUB.
I took the media that supposedly had the errors and am scanning it again with Rufus as we speak, but in the meantime I would like to try to understand the best process to recover from this error. I do have access to this machine all day and will gladly try whatever is asked of me. I don't have physical access though so I have to work with what is installed in the machine. I have a USB Drive with the 9.3 Installation, and the two USB Drives that were in the successful boot mirror still installed in the drive.
