+To report issues, please write **only** to difa.csi@unibo.it including a clear description of the problem ("my job doesn't work" is __not__ a clear description but is what we usually receive...), including jobID, misbehaving node(s), steps to reproduce, etc.

+===== 2025 =====
+==== 2025-05-09 ====
+  * slowness resolved (backup completed)
+==== 2025-05-08 ====
+  * generalized slowness: due to ongoing backup, access to /home is really slow. A concurrent check of the underlying RAID volume made it even worse. Check have been paused and backup is nearing completion, so the system should soon return to normality
+  * mtx12 is offline again due to RAM issues
+==== 2025-04-22 ====
+  * recreated missing reservations -- please check names with ''scontrol show res''
+  * mtx12 is (temporarily, we hope) down due to RAM issues
+==== 2025-04-18 ====
+  * Maintenance (nearly) completed. Two nodes are still down (gpu01 and gpu02), and some jobs migh have failed when scheduled on misbehaving nodes (bld17 and bld18, now fixed)
+  * **15:30 Update** all the nodes are currently working: don't break'em! Happy Easter!
+==== 2025-04-10 ====
+  * Created a reservation to avoid having running jobs during maintenance (**2025-04-16T10:00** to **2025-04-18T15:00**); we'll do our best to reduce downtime, so the cluster //might// come back online sooner than planned
+==== 2025-03-31 ====
+  * <del>We're experiencing issues with logins on bastion-nav from domain STUDENTI.</del> Fixed
+==== 2025-03-27 ====
+  * <del>/scratch and many nodes are currently down due to technical issues. We're working on it.</del> [9.00] Everything appears OK
+==== 2025-01-13 ====
+  * /archive is now **read-only** to avoid potential data loss during cluster move
 ===== 2024 =====
+==== 2024-12-18 ====
+  * Power sources are redundant again. There shouldn't be unexpected shutdowns till the "big one" on 2025-01-15
+==== 2024-12-17 ====
+  * Possibly unstable power source: rotative unit failed yesterday and is being worked on by CNAF. Some nodes powered off and have been restored. Uptime is currently not guaranteed in case of blackout.
