Hi folks, This chapter on sharding and how to configure it went into the RHGS 3.1 Administration Guide some time ago: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/chap-Managing_Sharding.html
If there's anything in here that isn't clear, let me know so I can fix it. It doesn't seem to show up if you search on the customer portal; I'll get in touch with JP Sherman and see what we can do about that.
