Hi Vincent,

We are working on supporting add and remove brick on a tiered volume. One patch is up in master branch towards this direction [1], which is still under review.

Till then , the work around to scale tier volume is to detach the tier, and then scale your cold tier, then reattach the hot tier after adding the bricks to hot tier.

Let me know if you have further queries

Hello,


Playing with Gluster 3.7(lastest), I would like to be able to add bricks to a hot tier.


Looks like not possible for now :

volume attach-tier: failed: Volume vol is already a tier.


I've seen similar request here :

https://bugzilla.redhat.com/show_bug.cgi?id=1229237

It's 3.1 and 2015


Anyone working on this must have feature  (at least to me)  ?

You know, data is growing, SSD are cheap and you want a bunch of them.


Vincent
