The source for frames 0 to 2 are not part of ceph, they are part of
glibc (libpthread).
This is what I normally do.
# apt-get install ceph-osd ceph-osd-dbg
# mkdir build && cd $_
# apt-get source ceph-osd
# cd ..
# gdb -d build/ /usr/bin/ceph-osd CoreDump
Something like that should work for you too (at least for the actual
ceph frames).

Hello,
I have a follow-up question. As the dbg packages in ubuntu, not like
rpm, don't have source code included, I also installed the source
package, and instruct gdb to find the directory with command
"directory /usr/src/ceph-14.2.7-75-g14b67dbc11", but it seems not
working:
(gdb) directory /usr/src/ceph-14.2.7-75-g14b67dbc11/src
Source directories searched: /usr/src/ceph-14.2.7-75-g14b67dbc11/src:$cdir:$cwd

could you help me with debugging in ubuntu environment?
Best,

Thanks for the reply. After some tinkering, I understand that
"make-debs.sh" intentionally remove *-dbg package building in normal
situations, quote "...and remove -dbg packages because they are large
and take time to build", so I comment out those lines:

now the script could generate *-dbg*.deb files as expected.
