issue in ceph_test_objectstore

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am hitting this issue when running ceph_test_objectstore with bluestore without bluefs.

Known issue or something wrong in configuration?

One suspicion is error of not able to find libsnappy.
