You seem to have thought a lot about this kind of setup... so I have another question...
You mentioned a pool of servers in your description of how load might be managed on NFS... but if a user already has a desktop running on a specific server have you considered any mechanism that might allow them to be re-connected to the node that has their running desktop?.. I guess some kind of long term sticky session load balancer might work "most" of the time... but ideally you'd want to check which host has their session already open... but this seems like a very hard problem. Also, I notice there is an option to kill disconnected sessions... is there a way to kill them after a set period of time, James On 17/05/15 10:24, Gustavo Homem wrote: > Hi, > > Looks good. > > If you are running for desktops for multiple users I'd recommend some > resource sharing measures: > > http://blog.angulosolido.pt/2013/11/fair-share-user-scheduling-on-linux.html > > This is to prevent a smart-ass user bringing the whole thing down.
