[Gluster-users] Convert to Shard - Setting Guidance

[Gustave Dahl]

I am looking for guidance on the recommend settings as I convert to shards.
I have read most of the list back through last year and I think the
conclusion I came to was to keep it simple.  

 

One: It may take months to convert my current VM images to shard's, do you
see any issues with this?  My priority is to make sure future images are
distributed as shards. 

Two:  Settings, my intent is to set it as follows based on guidance on the
Redhat site and what I have been reading here.  Do these look okay?
Additional suggestions?
