Hello, I am trying to set the extended attribute to a newly created created directory (call it "dir" here) using setfattr. I run the following command.
setfattr -n ceph.dir.layout.stripe_count -v 2 dir And return: setfattr: dir: Operation not supported I am wondering if the underlying file system does not support xattr. Has anyone ever run into similar problem before? I deployed CephFS on Debian wheezy. And here is the mounting information: ceph-fuse on /dfs type fuse.ceph-fuse (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other) Many thanks, Kevin On Mon Dec 15 2014 at 1:49:15 AM PST John Spray <john.sp...@redhat.com> wrote: > Yes, setfattr is the preferred way.
