- | Due to problems with the storage backend of an older virtualization cluster, there are currently massive problems when using some VMs, in particular: | ||
- | |||
- | * BigBlueButton Load Balancer (bbb.informatik.uni-bonn.de) | ||
- | * a central file server of the B-IT | ||
- | |||
- | as well as the machines | ||
- | |||
- | * vm-wuebbel-01 | ||
- | * sentry | ||
- | * mail-info4 | ||
- | * bbb4mm | ||
- | * leonov | ||
- | * inf1-srv-01 | ||
- | * login.bit.uni-bonn.de | ||
- | |||
- | The affected systems are immediately shut down completely in order to accelerate the repair of the affected storage backend. After repairs have been completed, the systems will be moved to a newer cluster in the short to medium term. | ||
- | |||
- | The central BigBlueButton IT service is also affected, the individual BBB servers are available (ongoing conferences are not affected), but new rooms cannot be opened or existing ones can be entered. I hope to be able to use the load balancer again tomorrow at the latest. | ||
- | |||
- | I apologize for the inconvenience, | ||
