Does anyone have any experience or know of any reasons to avoid running a Riak cluster with different filesystems backing different nodes?
With all other cluster components (hardware, OS, Riak version, Riak backend [leveldb], etc.) being equal, I'm really interested in doing a comparison of a node backed by XFS and one backed by ext4. I wondered whether we could simply do an A/B test by swapping out the filesystem on one node in the cluster and observing the impact that this has. I can't come up with any reasons why this is a bad idea, other than the obvious risk of impacting performance if the new filesystem performs much worse.
