 # Migration from old GPFS to new CephFS
+!!! warning "Important"
+    We will remove access to `/fast` on most cluster nodes following September 30th.
+
 ## What is going to happen?
 Files on the cluster's main storage `/data/gpfs-1` aka. `/fast` will move to a new file system.
 That includes users' home directories, work directories, and work-group directories.
