Hi There, I have a ceph cluster running on my proxmox system and it all seemed to upgrade successfully however after the reboot my ceph-mon and my ceph-osd services are failing to start or are crashing by the looks of it. ``` ceph version 17.2.6 (810db68029296377607028a6c6da1ec06f5a2b27) quincy (stable) 1: /lib/x86_64-linux-gnu/libc.so.6(+0x3bfd0) [0x7f10aba5afd0] 2: gf_init_hard() 3: gf_init_easy() 4: galois_init_default_field() 5: jerasure_init() 6: __erasure_code_init() 7: (ceph::ErasureCodePluginRegistry::load(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, ceph::ErasureCodePlugin**, std::ostream*)+0x2b5) [0x55b04c32c605] 8: (ceph::ErasureCodePluginRegistry::preload(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::ostream*)+0x9f) [0x55b04c32cbaf] 9: (global_init_preload_erasure_code(ceph::common::CephContext const*)+0x7c2) [0x55b04bdd9f92] 10: main() 11: /lib/x86_64-linux-gnu/libc.so.6(+0x271ca) [0x7f10aba461ca] 12: __libc_start_main() 13: _start() NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. ``` I am still quite new to Ceph and would like advice on how to troubleshoot this and get the services working again.
