Details about issue

I just can't get extended attributes to work with use_xattr. lsattr, chattr, rsync -aX all fail with some variety of "Function not implemented". I've looked through the Issues around implementing them (#460 #467 #471) and done some research, but I just get stuck with the same error.

I've used both the packaged EPEL s3fs-fuse and compiled from master, both have the same result.

The bucket filesystem works otherwise, I can add, update and remove files, change permissions, users etc. Just no xattr.

I've used the simpler s3fs command I provided above to make trying to get it work easier but I get the same error with either the fstab line or the s3fs (command) line.

# lsattr /mnt/bucket/test
lsattr: Function not implemented While reading flags on /mnt/bucket/test
# chattr +i /mnt/bucket/test
chattr: Function not implemented while reading flags on /mnt/bucket/test
# rsync -aX test /mnt/bucket/test
rsync: rsync_xal_set: lsetxattr(""/mnt/bucket/.test.GmyuLm"","security.selinux") failed: Operation not supported (95)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1178) [sender=3.1.2]

selinux itself is set to permissive for debugging so should not be an issue.

Edit: Apologies for confusing file attributes and extended attributes - not something I've really delved into before, but the above errors suggest neither work.

Many thanks

@snatella I'm sorry for my late reply.

This Issue seems to depend on fuse. I think fuse does not support lsattr / chattr.
