-Starting 2nd phase of migration from Alma Linux 8 to Alma Linux 9.  See [[../migration/alma9/plan#gradual_migration_of_compute_and_logininteractive_nodes]] for the details. This introduces the following changes:+  * gpu1.hb.hpc.rug.nl and interactive1.hb.hpc.rug.nl and the Digital Lab H100 node have been migrated to Alma Linux 9.
  
- * The special reservation for Alma 9 nodes has been removed and they are now part of the general pool +===== 2026-09-28 =====  
- * We will migrate more compute and GPU nodes to Alma Linux 9 + 
- * We will start migrating half of the login, interactive and interactive GPU nodes to Alma Linux 9. We have started with reinstalling interactive2.hb.hpc.rug.nl+  * All regular nodes have been migrated to Alma Linux 9. Thus, there are no more generally accessible Alma Linux 8 compute nodes left. The only exception pending migration scheduling is the private ''dl-h100gpu1'' node. 
 + 
 +===== 2026-09-15 =====  
 + 
 +  * All GPU nodes, except those in private partitions, have been migrated to Alma Linux 9 
 +  * All big memory nodes in the himem partition have been upgraded to Alma Linux 9 
 +  * The regular and parallel partition contain a mixture of Alma Linux 8 and Alma Linux 9 nodes. Reservations are in place for the these nodes to update the rest of these in several batches. 
 + 
 +===== 2026-09-07 =====  
 +  * login2.hb.hpc.rug.nl, interactive2.hb.hpc.rug.nl and gpu2.hb.hpc.rug.nl have been reinstalled with Alma Linux 9 
 +  * All partitions now contain a mixture of nodes running Alma Linux 8 and 9
