Hi,
I do rsync based backups against a cephfs. If I do sync xattrs, rsync
tries to delete ceph-internal xattrs (e.g. ceph.dir.entries) which fails
with an error. xattrs does not get synchronized in this case.
IMO the problem is, that ceph's internal attributes are exposed to the
mounted fileystem (I can do "getfattr -n ceph.dir.entries *" on the
mounted cephfs and get results). So rsync sees these xattrs and tries to
remove it.
Example output:
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.entries")
failed: Operation not supported (95)
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.files")
failed: Operation not supported (95)
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.subdirs")
failed: Operation not supported (95)
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.rentries")
failed: Operation not supported (95)
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.rfiles")
failed: Operation not supported (95)
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.rsubdirs")

rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.rbytes")
failed: Operation not supported (95)
rsync: rsync_xal_set:
lremovexattr(""/backups/2016-05-31_00-09-32/etc/acpi/events"","ceph.dir.rctime")
failed: Operation not supported (95)
Kind regards,
Michael.
