Thanks for the fast answer! Is there any (other) way to get a complete list of extended attributes? Is there something documented - meaning what can I rely on in the future?

I have a strange problem with ceph fs and extended attributes. I have two Centos machines where I mount cephfs in exactly the same way (I manually executed the exact same mount command on both machines). On one of the machines, getfattr returns this:
[root@ceph-01 ~]# getfattr -d -m 'ceph.*' getfattr: Removing leading '/' from absolute path names # file: mnt/cephfs/hpc/home ceph.dir.entries="49" ceph.dir.files="1" ceph.dir.rbytes="77816237666910" ceph.dir.rctime="1575978038.0976848840" ceph.dir.rentries="6673312" ceph.dir.rfiles="6271408" ceph.dir.rsubdirs="401904" ceph.dir.subdirs="48"
and on the other I get nothing:
[root@gnosis ~]# getfattr -d -m 'ceph.*' /mnt/cephfs/hpc/home
No error message, just nothing.
The only difference is, that ceph-01 was kickstarted with Centos7.6 while gnosis was kickstarted with Centos7.7. Otherwise, both machines are deployed identically. getfattr is the same version on both. Kernel versions are ceph-01:5.0.2-1.el7.elrepo.x86_64 and gnosis:5.4.2-1.el7.elrepo.x86_64.
Does anyone have a pointer what to look for?
recent version kclient/ceph-fuse hide ceph.* xattrs from listxattr(2) syscall. these xattrs still can be accessed by their names. such as getfattr -n ceph.dir.rctime /mnt/cephfs/hpc/home
Thanks!
