bareos-fd: symbol lookup error: /usr/lib/bareos/plugins/cephfs-fd.so: undefined symbol: ceph_create

The environment is:

OS: Debian 10.4 

Ceph: "ceph version 14.2.9 (2afdc1f644870fb6315f25a777f9e4126dacc32d) nautilus (stable)

Bareos: 19.2.7 (16Apr20) Linux-3.10.0-1062.18.1.el7.x86_64,debian,Debian GNU/Linux 10 (buster)

Don’t have any experience with this. But undefined symbol means a dynamic linker issue. The plunging looks like it can’t find some ceph library. 

Find what library provides ceph_create make sire it’s installed on the host with the fd. If it’s there check the environment that the fd starts in LD_LIBRARY_PATH env var includes that path. Might start the fd manually with that env to test before getting into init/systemd debugging. 

Sometime etc/ld.so.conf Is used In place of the variable.

Hi Brock,

the needed library is installed, under "/usr/lib/libcephfs.so.2.0.0", the both variables have this directory included, but the filedaemon didn't find it.
