We are testing running Ceph as a backend for Xen server acting as the client, and when a pool was created and mounted it as RBD in one of the client server, while adding data to it, we see this below error :
[939656.039750] libceph: osd20 10.255.0.9:6808 bad crc/signature
[939656.041079] libceph: osd16 10.255.0.8:6816 bad crc/signature
[939735.627456] libceph: osd11 10.255.0.7:6800 bad crc/signature
[939735.628293] libceph: osd30 10.255.0.11:6804 bad crc/signature
They are like 15 to 50 times in an hour when it happens, There are some hours when it don't happens there are 564 such errors since yesterday.
# uname -sr
# ceph -v
ceph version 12.2.0 (32ce2a3ae5239ee33d6150705cdb24d43bab910c) luminous (rc)
# cat /etc/*-release
CentOS Linux release 7.3.1611 (Core)
Any ideas why is this happening ?
