EA’s are probably Extended Attributes. Not sure though whether this error means the client is asking, or that the server has the EA’s and doesn’t know what to dow ith them.
At a guess, it’s on the server side. i’d investigate that.
XFS uses an “attr” command; i dunno what other filesystems use, or if they support the EA’s.
