(Get the code!)
I was able to get past this issue.
In my case, the ceph-mon was invoked by systemctl service file. So, I had to change the below property under the "[Service]" node of file: /lib/systemd/
- MemoryDenyWrite
+ MemoryDenyWrite
As per the system manpage[0]:
MemoryDenyWrite
Takes a boolean argument. If set, attempts to create memory mappings that are writable and executable at the same time, or to change existing memory mappings to become executable, or mapping shared memory segments as executable are prohibited. Specifically, a system call filter is added that rejects mmap(2) system calls with both PROT_EXEC and PROT_WRITE set, mprotect(2) or pkey_mprotect(2) system calls with PROT_EXEC set and shmat(2) system calls with SHM_EXEC set. Note that this option is incompatible with programs and libraries that generate program code dynamically at runtime, including JIT execution engines, executable stacks, and code "trampoline" feature of various C compilers.
This particular property was preventing the ceph-mon executable to run due to the above prohibitions.
After making the above change, I had to run
$ systemctl daemon-reload
And then restarting the service worked for me!
