To all users of the Supercomputer Systems:

File access to the Storage (home, LARGE0, LARGE1) from the computing nodes of the System D/E has occasionally been causing a long waiting time since the end of January.
The problem was temporarily resolved by eliminating the defective devices during temporary maintenance on 2/16, but the problem is recurring. We are very sorry for the continued unstable operation.

To address this issue, including changes to the network configuration between System D/E and Storage, we will conduct urgent system maintenance again as follows.
The end time has not been accurately estimated and will be announced if any changes occur.

Maintenance Period: 1:00 p.m. on Fri. February 24, 2023 - 10:00 a.m. on Tue. February 28, 2023
Systems to be suspended: System D/E/G, Cloud system, and Storage

All running jobs will be re-executed following this maintenance.
Jobs for which re-execution is prohibited will be forced to terminate,
so please re-submit the positions after the system starts the operation.

We apologize for any inconvenience caused and ask for your understanding and cooperation.
