Can't remove ceph xattrs on linux

I had set xattrs for quota limits on CephFS $ setfattr -n ceph.quota.max_bytes -v 1100000000 /mnt/cephfs/data/ I can get value of this attribute $ getfattr -n ceph.quota.max_bytes /mnt/cephfs/data/ getfattr: Removing leading '/' from absolute path names # file: mnt/cephfs/data/ ceph.quota.max_bytes="1100000000" But then I try to remove quota, I had $ setfattr -x ceph.quota.max_bytes /mnt/cephfs/data/ setfattr: /mnt/cephfs/data/: No such attribute How can I remove this xattr?
