Mount using fsspec.fuse.run with AzureDatalakeFileSystem filesystem on Ubuntu 18 not working #536

Open tomasro27 opened 3 years ago

Hi, I'm trying to mount an AzureDatalakeFileSystem (from adlfs python package) using fsspec.fuse.run. However, after calling the run method, I can't access the mount_point folder. For example, I used mount_point /tmp/test1/. It looks like mount was successful, but if I try to 'ls' on the parent directory, I get: "ls: cannot access 'test1': No such file or directory" If I cd into that folder, the folder is empty. And doing 'ls' inside that folder gets: "ls: cannot open directory '.': No such file or directory" The only way to get the folder back to a good state is to sudo umount /test1/

I looked around and some people suggest changing directory permissions. Others suggest editing etc/fuse.conf file to include user_allow_other. But to no avail.

There is no much documentation on using run(), but I successfully created AzureDatalakeFileSystem, and I can interact with this and see the contents of the filesystem. However, run() does not seem to properly mount. Any help or guidance here would be appreciated. Thanks

"No such file or directory" sounds like the mount did not in fact work. I'll try to find some time to try it in linux; though, honestly, fuse has always been little-used because the performance will be poor.

Thank you - let me know if you hit the same issue or not

I did not see this problem. However, I am not running with abfs (I don't have an account). It may be sensitive to how you use slashed ("/") in the root path you want to mount.
