[fuse-devel] SETATTR error: -38 (Function not implemented)

[andreas b. <ab...@gm...>]

Hi,

I am writing a new fs and have the problem that a binaray file could not copied.

The reason seems that the SETATTR functions is not implemented (but BTW it could not be set in the fuse_operations).


My call is 'cp -r  dtsmfs /mnt/tsm' where /mnt/tsm is my fuse fs.

Problem:

>   unique: 31, error: -38 (Function not implemented), outsize: 16

Any idea how to fix this?


Greetings -- Andreas
