Hi all,
We are working on use CEPH to build our HA system, the purpose is the system should always provide service even a node of CEPH is down or OSD is lost.
Currently, as we practiced once a node/OSD is down, the CEPH cluster needs to take about 40 seconds to sync data, our system can't provide service during that.
My questions:
- Does there have any way that we can reduce the data sync time?
- How can we let the CEPH keeps available once a node/OSD is down?
BR
