Error: manifest has unsupported version: 2 (we support 4)

[leerspace]

Version information:

go-ipfs version: 0.4.12-rc2-
Repo version: 6
System version: amd64/linux
Golang version: go1.9.2

Type: Bug

Severity: Critical

Description:

The IPFS daemon fails to start after updating to v0.4.12-rc2. It fails with an error message saying

Initializing daemon...
Error: manifest has unsupported version: 2 (we support 4)

This looks like it might be coming from badger.

[leerspace]

It looks like the on-disk format for badger changed with #4364 and #4327. So this is probably expected.

[magik6k]

This is expected, there is a WIP tool for that - ipfs-inactive/badgerds-upgrade#1 - if you really want to, you may give it a try:

• Build it
• Make sure your daemon isn't running
• Make a backup of ~/.ipfs (or wherever your repo is)
• Run the tool

[magik6k]

Once ipfs-inactive/badgerds-upgrade#1 gets merged I'll add a better error message to badgerds.

[leerspace]

That seemed to work without issues as far as I can tell. I've only run it so far on a mostly empty repository, but I can now use v0.4.12-rc2 on it!

Is this expected to be something that automatically gets run when v0.4.12 is released (if an older badger datastore is detected)? Or will it be a manual upgrade?

[whyrusleeping]

@leerspace as badger is currently experimental, it will not be run automatically. Moving forward though, this sort of thing will likely be included as a migration between versions. Now that datastores are user-configurable we need to look into more advanced upgrade management.

[leerspace]

Thanks for the info. I won't wait for 0.4.12 with the expectation that it will be an automatic badger update and will instead update my nodes manually (using magik6k's badgerds-upgrade utility).
