[Gluster-users] Working and up to date guide for ganesha ? nfs-ganesha gluster-ganesha

[Travis Eddy]

I was mistaken...
Genesha wasn't working. Glusters NFS was still on. :-/
so i fixed that....

XenServer (7.1) can't seem to mount NFS-Genesha, nfs v3 or v4, or using the
xe command. (sr_backend_failure_73)

A Centos 7 box can, but not XenServer... I think thats the last nail :-/
back to the shelf Gluster goes sorry :-(, it works well for generic file
server purposes but now a storage server (or cluster) _must_ handle VM
images :-/ and with usable speed. I'll probably test it again in a year or
so. I keep coming back since I first tested it years ago (and deployed to a
few customers)  Gluster is cool.  maybe oVirt will have a more viable UI
then too. But I am testing  Proxmox  next so ;-).
