Description

ipfs daemon --mount

does not work. I have seen similar issues reported here but I couldn't find this exact same issue.

kubo is installed through the Manjaro repositories. I have also tested this with the v0.26.0 binary downloaded from Github and a colleague confirmed the issue.

I have created /ipfs and /ipns and the folders belong to me

$ ll / | grep ip                                                                         
drwxr-xr-x   2 gkraemer gkraemer 4.0K Feb 12 22:17 ipfs
drwxr-xr-x   2 gkraemer gkraemer 4.0K Feb 12 22:17 ipns

after launching ipfs daemon --mount, something gets mounted in these folders

$ ll / | grep ip                                                        
d--x--x--x   1 root root    0 Feb 14 21:13 ipfs
d--x--x--x   1 root root    0 Feb 14 21:13 ipns

trying to access anything from these folders tells me "No such file or directory".

I have tried setting user_allow_other and changing the permissions of the directories while unmounted and mounted but to no avail.

How are you running kubo? Are you running ipfs daemon as root (shouldn't be needed), the folder permissions changing looks suspicious.

3ri4nG0ld commented 9 months ago

This feature could be reimplemented using "ipfs filestore", I don't know if something similar is already thought of, or if you plan to keep the --mount, but both methods would seem useful to me.

I don't run kubo as root.

Basic checklist for FUSE-mounting IPFS:

"ipfs config --json Mounts.FuseAllowOther true" (= JSON '"Mounts":{"FuseAllowOther":true,')
"user_allow_other" in /etc/fuse.conf (not commented out with "#" at the start of the line)
/ipfs and /ipns mountpoints owned by a basic or non-root user - those folders should exists (run "sudo chown user /ipfs /ipns")
something published to IPNS - seems you gotta have an IPNS record for your peerID to mount IPFS (run "ipfs daemon &", "ipfs name publish baf...", "ipfs shutdown", then the mount command which is "ipfs daemon --mount &")
running a 64-bit computer (doesn't work in 32-bit ones)

I know you said that you already did some of these things, but you didn't comment on the other things. Oh wait, I see that you posted '"FuseAllowOther": false,' - and that's almost certainly your problem.

Author input needed to mark this issue as solved?

Thanks for looking at this. I followed the steps and get a different error now:

It didn't work because you tried to publish a file to IPNS. You can only publish a folder to IPNS (I didn't write that in my steps). Run something like this (folder contains darkhttpd web server source code): "ipfs name publish /ipfs/bafybeiawvadz46hpwl2hw2darjone46gvajm7td4dgowjpdvz5f5eee7qi".

Above in this thread, I said that mounting IPFS doesn't work in 32-bit computers. That's not entirely correct. It didn't work in a specific ~decade-ago version of a certain Linux distro. This month I saw that I could mount IPFS in a 32-bit computer which is basically running a liveboot of the latest Debian. (Now my problem is that I cannot run Tor and torsocks in said 32-bit computer, even after hours of trying to fix it.)

Thanks for taking the time to debug this for me! It works now for me.
