Urgency: Emergency
Affected services:
- Shared storage
- Shared hosting
- E-mail services
- VNC (console) access to virtual machines in BIT portal
Expected impact:
- Short-term unavailability of the above affected services
- Shared file system (CephFS) unavailable for a short time (possibly several times)
Customer intervention required: No
Reference number: 179244
Summary:
Modified software will be installed on the Ceph Metadata (MDS) servers. The CephFS cluster will not be redundant and temporarily unavailable at certain times during this maintenance.
Details:
This emergency maintenance is performed to patch a bug in the software. During maintenance, the shared file system, CephFS, will be temporarily unavailable at least once, but possibly several times. The MDS servers will be provided with modified software, which will require the servers to be restarted. These restarts will cause short interruptions. During the maintenance of the standby MDS server, the CephFS cluster is temporarily not redundant.
