Go-ipfs: Leveldb corruption

Version information:

go-ipfs version: 0.4.12-rc1-8ec1ce9e

Bug

Description:

• What you were doing when you experienced the bug.

I played around a bit with launching/killing ipfs, because it was using a lot of ressources, and it kept rebooting.

• Any error messages you saw, where you saw them, and what you believe may have caused them (if you have any ideas).

The actual bug is that when I want to actiate it now, with ipfs deamon I obtain the following:

Initializing daemon...
Adjusting current ulimit to 2048...
Successfully raised file descriptor limit to 2048.
Error: leveldb: manifest corrupted (field 'comparer'): missing [file=MANIFEST-000224]

From what I know there is an easy way to fix this, however I do not know the location of the said database.

Thanks for your help!

Please always try to shutdown IPFS gracefully to prevent corruption.
LevelDB files by default should be stored in ~/.ipfs/datastore.

Please always try to shutdown IPFS gracefully to prevent corruption.

Note: IPFS should recover from a crash. This is a bug.

Just in case it helps, the repair from python worked perfectly well!

how to recover the file?

[Magalame]

$cd ~/.ipfs/datastore
$ python
…
>>> import leveldb
>>> leveldb.RepairDB("./")

Make sure you have leveldb installed first

[domainvip]

leveldb.RepairDB("~/.ipfs/datastore")
Traceback (most recent call last):
File "", line 1, in
leveldb.LevelDBError: IO error: ~/.ipfs/datastore: No such file or directory

[Magalame]

Try that:

$cd ~/.ipfs/datastore
$ python
…
>>> import leveldb
>>> leveldb.RepairDB("./")

[domainvip]
