Hi Ilya, hmm, OK, I'm not sure now whether this is the bug which I'm experiencing.. I've had read_partial_message / bad crc/signature problem occurance on the second cluster in short period even though we're on the same ceph version (12.2.5) for quite long time (almost since its release), so it's starting to pain me.. I suppose this must have been caused by some kernel update, (we're currently sticking to 4.14.x and lately been upgrading to 4.14.50) not sure whether this in is of some use..
