Unfortunately you did not really enable the debugging messages or you
forgot to type "dmesg". Anyway, they are absent.

Can you actually enable them and share the log? Or may be you can dump
the image and share it - I should be able to put it to nandsim and try
to mount and see.

Looks like old master node was for some reason selected for some reason
- I'd first looked to the master area. But most probably it was already
cleaned-up when you tried to mounted for the very first time after the
power cut. Do you have kernel logs of that ? Are there messages about
corrupted master node?

Is this problem reproducible?
