Greetings all!
I previously wrote about a broken 3 way RAID 1 ZFS root pool.. I thought I had that all cleared up, but now I'm STILL getting file systems warnings. The problem appears to be rooted in the 3way RAID 1 gmirror that used to use the now dead ada0p2 device.
gmirror claims to be in a degraded state, and this is true - ada0 is toast, and I'm fine with that for now.. But no matter how I query it, I can't see how to clear the status? It will tell me about the CURRENT visible devices, but not about MISSING devices? I found one tiny little reference on the internet, that sort of inferred it's just not possible? "Since we can’t remove the dead disk from the gmirror setup, first we forget then add the new swap partition back in."
I'm not clear on the extent of "gmirror clear" does - if we're talking all the "metadata", does that just erase the entire mirror?
So... What, temporarily add a file a swap, remove swap, destroy gmirror, recreate gmirror, re-add to swap space? Is that the outline of what I'm looking at here?
Thanks in advance..
