Scheduled maintenance of the MetaCentrum Cloud

20.6.2023 5-10PM - Scheduled maintenance of the MetaCentrum Cloud

Dear user of Cloud MetaCentrum [1],

There will be a reconfiguration of the Metacenter OpenStack cloud block storage in order to increase its capacity scheduled on Tuesday 20.6. between 5:00 PM and 10:00 PM CET.
From our experience we know that even little configuration change may cause a short outage (10-30 minutes) in relation with approximately 3K volumes that are now allocated. VMs operations will not be affected, the Main OpenStack API will be available as well as the Horizon UI, Cinder block storage and API will be temporarily unavailable preventing volumes creation.

We apologize for any inconvenience,

MetaCentrum Cloud team
