Completely clean log. head/tail at 2/16292. Yet the AGF head and a couple of btree blocks are have bad CRCs. They were on disk *before* the system crashed. > Metadata after an attempt to mount: https://clbin.com/2jayF Dirty log. tail at 2/16292, head at 2/16332. The before-mount image shows the CRC error, so it didn't come from log recovery. It may have come from recovery in the previous iteration, - do you still have the pre-mount images from the prior iteration before the crash error was detected?
