What did happen ?

We start to extend our cloud storage on Wednesday morning in preparation of our
planned Openstack upgrade. During the extension process two of seven storage
nodes had a hardware problem. At the same time we increased the number of

However,  the failure of two nodes and the high number of placement groups lead to a
dead lock, which must be solved manually.

Sorry for any inconvenience,
