Gluster users - May 2016 - Volume Tiering

Hi Lindsay,

Volume level data tiering was made fully supported in latest 3.7
releases, though an active effort is still going on to increase the
small file performance. You can find a starting point through the blog
post by Dan [1].

Let me know if you have any additional questions.

Thanks Mohammed, an informative read. When things have settled down a 
bit at work I'l setup a test volume to attach tiers to. Ironically, now 
we've migrated the production env to gluster, my ability to test is 
lessened  - can't tweak it arbitrarily now :)


Some questions:

- Does the hot tier replication level have to match the cold tier? i.e 
brick for brick?

- I presume the files are promoted across all bricks. i.e you can't have 
different files promoted per brick.

- With sharded volumes its the individual shards that are promoted?



thanks,
