Hello, We are running Luminous 12.2.2. 6 OSD hosts with 12 1TB, and 64GB RAM. Each host with a SSD for Bluestore's block.wal and block.db. There are 5 monitor nodes as well with 32GB RAM. All servers have Gentoo with kernel, 4.12.12-gentoo. When I export an image using: rbd export pool-name/volume-name /location/image-name.raw The following messages show up. The signature check fails randomly. The image is still exported successfully. 2018-01-24 17:35:15.616080 7fc8d4024700 0 cephx: verify_authorizer_reply bad nonce got 4552544084014661633 expected 4552499520046621785 sent 4552499520046621784 2018-01-24 17:35:15.616098 7fc8d4024700 0 -- 172.21.32.16:0/1412094654 >> 172.21.32.6:6802/6219 conn(0x7fc8b0078a50 :-1 s=STATE_CONNECTING_WAIT_CONNECT_REPLY_AUTH pgs=0 cs=0 l=1)._process_connection failed verifying authorize reply 2018-01-24 17:35:15.699004 7fc8d4024700 0 SIGN: MSG 2 Message signature does not match contents. 2018-01-24 17:35:15.699020 7fc8d4024700 0 SIGN: MSG 2Signature on message: 2018-01-24 17:35:15.699021 7fc8d4024700 0 SIGN: MSG 2 sig: 8189090775647585001 2018-01-24 17:35:15.699047 7fc8d4024700 0 SIGN: MSG 2Locally calculated signature: 2018-01-24 17:35:15.699048 7fc8d4024700 0 SIGN: MSG 2 sig_check:140500325643792 2018-01-24 17:35:15.699049 7fc8d4024700 0 Signature failed. 2018-01-24 17:35:15.699050 7fc8d4024700 0 -- 172.21.32.16:0/1412094654 >> 172.21.32.2:6807/153106 conn(0x7fc8bc020870 :-1 s=STATE_OPEN_MESSAGE_READ_FOOTER_AND_DISPATCH pgs=26018 cs=1 l=1).process Signature check failed Does anyone know what could cause this, and what I can do to fix it.
