Hi I'm looking for an advise on hot tier feature - how can I tell if the hot tier is working? I've attached replicated-distributed hot tier to an EC volume. Yet, I don't think it's working, at least I don't see any files directly on the bricks (only folder structure). 'Status' command has all 0s and 'In progress' for all servers. ~]# gluster volume tier home status Node Promoted files Demoted files Status --------- --------- --------- --------- localhost 0 0 in progress MMR11 0 0 in progress MMR08 0 0 in progress MMR03 0 0 in progress MMR02 0 0 in progress MMR07 0 0 in progress MMR06 0 0 in progress MMR09 0 0 in progress MMR12 0 0 in progress MMR10 0 0 in progress MMR05 0 0 in progress MMR04 0 0 in progress Tiering Migration Functionality: home: success I have a folder with .yml files (Ansible) on the gluster volume, which as I understand is 'cache friendly'. No matter how many times I read files, nothing is moved to the hot tier bricks. Thank you. -------------- next part -------------- An HTML attachment was scrubbed...

Hi, If it was just reads then the tier daemon won't migrate the files to hot tier. If you create a file or write to a file that file will be made available on the hot tier.
