Corrupt DB after a power failure

[esaumell]

Hi, I would like to recover data. I'm getting a panic: invalid freelist page: 1938, page type is leaf. As mentioned on #135 I've tried bbolt check host.db but any operations with bbolt are giving that same error.

I thought that maybe the end of the file was corrupted and I was wondering if it would be possible to strip that corrupted data from the file.
I've tried opening the db file with an hex editor and I can read some of the data. I tried some arbitrary deletions without success.

Anyone has experience with this? Would be nice to recover at least part of the file in a working state.

yes, I have also experienced this before. Sadly till now I haven’t found any solution for this

@esaumell What exception stack trace do you get from bbolt check?

Hey sorry to say I no longer use the software that used bbolt as DB... For me the issue can be closed. Thanks anyway.

For posterity:

I recommend:

./bbolt page --all --format-value=redacted data/member/snap/db

to diagnose the structure of the tree... and have data that after inspection can be shared with others for help (no values - just keys -> that in case of etcd, does not carry any business-data).
