Why is my program's core dump always zero bytes, when run on an NTFS partition mounted in Linux?

Question

I'm trying to get a usable core dump from code that I am writing. My source is on a NTFS partition that I share between Windows and Linux OSes. I'm doing the development under Linux and have set ulimit -c unlimited in my bash shell. When I execute the code in my project directory on the NTFS partition, and purposely cause a SIGSEGV or SIGABRT, the system writes a core dump file of zero bytes.

If I execute the binary in my home directory (an ext4 partition), the core dump is generated fine. I've had a look at the man page for core, which gives a list of various circumstances in which a core dump file is not produced. However, I don't think it's a permissions issue as all the files and directories on that partition have full rights (chmod 777).

Any help or thoughts appreciated.

Answer 1

Maybe you should check the this file (/proc/sys/kernel/core_pattern)

Answer 2

The directory where the application sits is a mount point to another linux machine. The core file can't be written to a mounted drive but must be written to the local drive.

You can create ram disk and put the core dump on the ram disk.
