One suggested method of recovering RAID from a > degraded situation is to rebalance over just the remaining devices > (space permitting, of course). Right but that's not a conversion. That's a regular balance on a degraded mount, with multiple remaining devices: e.g. a 4 disk raid1, drive fails, mount -o degraded, delete missing, then balance will replicate any missing 2nd copies onto three drives. The bigger problem at the moment is that -o degraded isn't working for Johan. The too many missing devices message seems like a bug and with limited information it may even be whatever that bug is, that cause the conversion to fail. Some 11GB were converted prior to the failure.
