We have experienced a problem with one of the servers in the cluster, VPS cannot access some data.
Update(s):
Date: 2016-06-22 11:18:14 UTC We have manually exported and imported both of the impacted PG on two new OSD.
Date: 2016-06-22 11:17:30 UTC The whole cluster is now reachable, more information to come.
Date: 2016-06-22 11:17:20 UTC A solution had been tested in a test environnement, we will use it on production.
Date: 2016-06-22 11:15:58 UTC 0.04 % of data in the cluster cannot be accessed.
If a VPS attempts to access this data, the cluster will not return any information, which generates errors on the VPS.
