Description

On CentOS 7 which has "systemd-run" binary exists, when we use /etc/init.d/ceph to start ceph daemons, we do find that do_cmd_okfail in ceph_common.sh sets "ulimit -c unlimited", but after the daemon receives a signal, like 11(SIGSEGV), no core file generated.

If we add the "ulimit -c unlimited" in systemd-run cmdline as follows, everything will be OK.

cmd="$SYSTEMD_RUN -r bash -c 'ulimit -c unlimited;$files $cmd --cluster $cluster --setuser ceph --setgroup ceph -f'"

BTW, we have set /proc/sys/kernel/core_pattern properly.
