"fuse: panic in handler for Setattr" after copying file to mounted remote filer

[jonathonf]

I might be doing something wrong here, but here goes...

I have a weed server -ip="10.0.0.1" -ip.bind="10.0.0.1" (Debian Buster) with a complete security.conf (following https://github.com/chrislusf/seaweedfs/wiki/Security-Configuration) and set of keys and PEMs in $HOME/.seaweedfs. I have copied $HOME/.seaweedfs to a client machine (Manjaro) and mounted with weed mount -filer="10.0.0.1:8888".

Both are using the 1.58 binary release.

When I copy a file to the mounted FS, on completion the client process panics:

Trying to access the file results in an IO error:

$ file file.txt
file.txt: cannot open `file.txt' (Input/output error)

Thanks for reporting! It is a code bug, not your fault. Fixed just now.

[chrislusf]

you can use 1.59 release now.
