Hi,

I made a fresh install of Ceph Octopus 15.2.3 recently. And after a few days, the 2 standby MDS suddenly crashed with segmentation fault error. I try to restart it but it does not start. [...]

Can you please increase MDS debugging: ceph config set mds debug_mds 20 for the time it takes to reproduce. Then the core dump may also be helpful: https://docs.ceph.com/docs/master/man/8/ceph-post-file/ -- Patrick Donnelly, Ph.D. He / Him / His Principal Software Engineer Red Hat Sunnyvale, CA GPG: 19F28A586F808C2402351B93C3301A3E258DD79D
