Correct, but even increasing the max_connections in your MySQL configuration may not be enough. Look at your system ulimit, or in or around /etc/sysconfig/limits.conf where a system-level governor is defined for max_connections (on centos). Cheers, -E On Thu, Aug 17, 2017 at 3:32 AM Arne

Looking for a Workgroup or BoF at the Boston Summit where we can discuss the design and use of a Ceph-backed OpenStack cloud environment for research computing with protected data (e.g., NIH GDS, HIPAA, FedRAMP, etc.). If anyone thinks this is a fit for their group, let me know. Cheers, -E --

[Openstack-operators] status of encrypted volumes in RBDDriver (Cinder)

2017-02-28 Thread Evan Bollig PhD
Does anyone have LUKS encrypted volumes running on Ceph RBD? I have not found any recent (2017) updates on whether this is functional. >From what I understand, it was waiting for the release of QEMU 2.6.0 (which is out now). If functional, what major/minor version of cinder is needed? Any
