Hi,

I am currently trying to implement an option to utilize Ceph’s Bluestore as an backend for the storage framework JULEA, but I am currently stuck on an error when I’m using ObjectStore::create to initialize the ObjectStore.

I’m initializing Ceph beforehand using the global_init, but on calling of ObjectStore::create(https://github.com/JCoym/julea/blob/3866a3cc2edfda6a09ee84808c7ea5c4195d2aa6/bluestore/julea_bluestore.cc#L61) I get a SegFault from a mutex function of Ceph.

I have currently no idea what causes this error, so I would be glad if someone has an idea what I’m missing.

Thanks,

Johannes
