Hello all, after upgrading Centos clients to version 8.4 CephFS ( Kernel 4.18.0-305.3.1.el8 ) mount did fail. Message: *mount error 110 = Connection timed out* ..unfortunately the kernel log was flooded with zeros... :-( The monitor connection seems to be ok, but libceph said: kernel: libceph: corrupt full osdmap (-2) epoch off xxxxxxxxxxxxx of yyyyyyyyyyyyyyy After client VM restore with Kernel 4.18.0-240.22.1.el8_3.x86_64 everything runs well. Did someone recently upgrade clients to Centos 8.4?
