Could you please check if libfio_ceph_objectstore.so has been rebuilt
with your last build?

Thanks for your suggestions.
I tried to build libfio_ceph_objectstore.so, but it fails to load:
```
$ LD_LIBRARY_PATH=./lib ./bin/fio --enghelp=libfio_ceph_objectstore.so
fio: engine libfio_ceph_objectstore.so not loadable
IO engine libfio_ceph_objectstore.so not found
```
I managed to print the dlopen error, it said:
```
dlopen error: ./lib/libfio_ceph_objectstore.so: undefined symbol:
_ZTIN13PriorityCache8PriCacheE
```
I found a not-so-relevant
issue(https://tracker.ceph.com/issues/38360), the error seems to be
caused by mixed versions. My build environment is CentOS 7.5.1804 with
SCL devtoolset-7, and ceph is latest master branch. Does someone know
about the symbol?

Besides already mentioned store_test.cc one can also use ceph
objectstore fio plugin
(https://github.com/ceph/ceph/tree/master/src/test/fio) to access
standalone BlueStore instance from FIO benchmarking tool.
Thanks,
Igor

Hi,
I'd like to run a standalone Bluestore instance so as to test and tune
its performance. Are there any tools about it, or any suggestions?
Best,
