Description

Operation of CEPH in a mixed cluster consisting of little and big endian nodes triggers CRC inconsistency during OSDMap incremental update in
OSD::handle_osd_map().
Initial check revealed that the OSDMap::crc is not equal to the OSDMap::Incremental::full_crc
and the OSDMap::crc is not properly calculated in the "void OSDMap::encode(ceph::buffer::list& bl, uint64_t features) const" function.
A typical warning message "failed to encode map" is logged (see the screensot in the attach).
