[Gluster-devel] iSCSI

[Prasanna Kalever]

Hi Francis,


The tcmu-runner is not available as a pre built package in Ubuntu distro,
so you need to build it on your own, honestly I have not tried this on my
own but the suggested solution should solve it for you.

glfs is supported from initial version of tcmu-runner, so you can take up
any latest version of it.

perform cmake . -Dwith-glfs=true followed by make

that's not all, you need to manually copy the systemd unit files
(tcmu-runner.sevice) the respective directives and copy the handlers (in
our case 'handler_glfs.so' to /usr/lib/tcmu-runner/) and other required
conf files


take a look at the fedora rpm spec, which should be a way to follow
[...]
%install

make install DESTDIR=%{buildroot}

mkdir -p %{buildroot}%{_mandir}/man8/

install -m 644 tcmu-runner.8.gz %{buildroot}%{_mandir}/man8/



%post -n libtcmu -p /sbin/ldconfig



%postun -n libtcmu -p /sbin/ldconfig



%files

%{_bindir}/tcmu-runner

%dir %{_libdir}/tcmu-runner

%{_libdir}/tcmu-runner/*

%{_sysconfdir}/dbus-1/system.d/tcmu-runner.conf

%{_datarootdir}/dbus-1/system-services/org.kernel.TCMUService1.service

%{_unitdir}/tcmu-runner.service

%doc README.md

%license LICENSE

%{_mandir}/man8/tcmu-runner.8.gz





%files -n libtcmu

%{_libdir}/*.so.*



%files -n libtcmu-devel

%{_includedir}/libtcmu.h

%{_includedir}/libtcmu_common.h

%{_libdir}/*.so
[...]


list of things you need to do:
1. do the path changes in the systemd unit file tcmu-runner.service and
copy it to /lib/systemd/system/
2. copy the libraries to respective paths
3. mkdir and copy handler_glfs.so to /usr/lib/tcmu-runner
4. copy the tcmu-runner.conf   to /etc/dbus-1/system.d/
5. copy org.kernel.TCMUService1.service to /etc/dbus-1/system-services/
6. make sure target_core_user is loaded and target.service is running
7. run systemctl start tcmu-runner.servie

Hopefully that should work!

Looking forward for your update.

Cheers,
