[Gluster-users] Gluster tier in progress after attach
I see it still not promoting any files. Do we need to run any command to force the movement? This would be an issue if we need to expand disk as then we also need to detach existing tier and attach again and expect the data to be promoted to the hot tier. Regards, Jeevan.

Are those files being accessed? Tiering will only promote those that have been accessed recently.
