Hi all!
I made GlusterFS volume based on few HDD at few servers and I wanted to add SSD
based tiering. Write-back caching is problem for this case, because SSD are in
only one server, so its failure results in failure of all tier and data loss.
I want to disable write-back caching and write from client nodes directly to HDD
volume (cold tier). How can I do that?
My cluster is based on GlusterFS 3.10 and Debian 8.
Regards,
Bartosz
