The build-id is dependent on the exact version/release of the package.
glusterfs-debuginfo-3.8dev-0.58.gitf692757.el7.centos.x86_64 does not
contain that build-id. There should be a different version of the
glusterfs packages that caused the coredump.

After enabling the yum repositoty for the nightly builds of the master
branch, I executed the suggested yum command:

    # yum --enablerepo='*debug*' install \
      /usr/lib/debug/.build-id/0c/ae3265b0e4eb0eb92890732b979886a34c5524

This went through, and asked me to install glusterfs-debuginfo with
version/release 3.8dev-0.12.gitaa87c31.el7.centos. You should be able to
downgrade the glusterfs packages (or install a clean system with that
version) and you can then look into the coredump.

Because 'glusterd --xlator-option *.upgrade=on -N' is the command that
failed, I guess that the core was generated during an update process. It
sound possible that the packages got updated because the failing of the
glusterd command was not fatal.

HTH,
Niels
