I installed with my root pool as rpool
before the installer had the option.
My main HDD bit the dust, so I'm now in the process of resilvering and in the meantime I am reinstalling grub on the new drive. Unfortunately I cannot get ZFS to be properly detected. I get the dreaded error: unknown filesystem.
error from grub.
Note that I don't think it has anything to do with resilvering because I am probing an existing [not new] device.
You'll see that it passes all checks except #12 which seems to be the feature check. I don't see any feature error in the log however. I have all the 0.8.3 features enabled.
Can I force it to detect as ZFS, or is there a way to fix grub?
