On Thursday 22nd June, between 09:00 and 12:00 the following system interventions are scheduled:
1) Expansion of network subnet used by JASMIN unmanaged cloud:
Brief interruption to network connectivity for all virtual machines in the JASMIN Unmanaged Cloud.
2) Kernel updates to virtual machines in the Managed infrastructure.
This affects ALL jasmin-login, jasmin-sci, jasmin-xfer and project-specific VMs as well as service hosts (affecting CEDA services running on these hosts). Machines will be rebooted after a kernel update has been applied, resulting in a brief loss of connectivity or service operation. Machines will be updated in batches, with system broadcast messages to logged-in users issued shortly (10 mins) before each reboot.
We apologise in advance for any inconvenience caused by this essential maintenance work.
CEDA / JASMIN Team
