IPFS repo cannot be stored on a NAS (SMB, etc.).

[madranet]

Version information:

go-ipfs version: 0.8.0 Repo version: 11 System version: amd64/darwin Golang version: go1.15.8

OSX Version: 10,14,8

Description:

As per title. IPFS worked fine with default setup [ie. storing data locally]. I then tried to move my repo to a NAS [mounted via SMB] by adding export IPFS_PATH=/Volumes/stuzbot/IPFS to my ~/.zshrc file and re-initialising.

Now, when I run ipfs daemon I get the following error:

Initializing daemon...
go-ipfs version: 0.8.0
Repo version: 11
System version: amd64/darwin
Golang version: go1.15.8

Error: cannot acquire lock: Lock FcntlFlock of /Volumes/stuzbot/IPFS/repo.lock failed: operation not supported

I've tried both reinitialising the repo from scratch at the new NAS location with ipfs init and also copying over the existing contents from the old default ~/.ipfs location. But I get the same error each time. I can see that, after running ipfs daemon a zero bytes repo.lock file is actually created in the repo directory but the error message still persists.

I have full read/write permissions for the NAS itself and for the directory I am trying to use as my IPFS repo.

Unfortunately, SMB doesn't support file locks which are required by go-ipfs. Furthermore, performance is likely going to be absolutely terrible if you want to put your entire repo on a remote machine so the likelihood of anyone trying to make this work in the future is pretty low.

If you want to do this, I recommend mounting your SMB directory under ~/.ipfs/blocks so that only the blockstore (where most of the data goes) gets stored on the remote machine.

As simple as that eh? That was what I wanted to know anyway. How to move the actual data onto an external HDD. I thought it might involve a lot of complex config jiggery-pokery. There's enough room on the Raspberry Pi to store the other 'stuff' but the actual file data needs to be somewhere else. I'll give this a go and see if it works.

Yep, as long as you're using the default datastore configuration (if you see a "blocks" directory, putting that directory on the NAS should do it).
