UBIFS error (pid 564): read_znode: bad indexing node at LEB 484:66064, error 2

I had a power outage yesterday. When things came back and I tried to
boot my guruplug, I am not getting the following:

[   97.273764] UBIFS error (pid 564): read_znode: bad indexing node at LEB 484:66064, error 2
[   97.282188] UBIFS warning (pid 564): ubifs_ro_mode: switched to read-only mode, error -22
[   97.290431] UBIFS error (pid 564): ubifs_budget_space: cannot budget space, error -22

The filesystem is read-only and I can't seem to figure out how to get it
out of this state. As far as I can tell, there is no fsck.ubifs and I'm
at a loss at how to get things back to a reasonable state. I found the
'nandtest' command, which might be useful for mapping out bad areas, but
I'm not going to run that without a better clue at how likely I am to
brick things.

Thanks for any suggestions or help!
