[pve-devel] applied: [PATCH cluster v2 2/3] RRD: fetch data from old rrd file if present and needed

[Aaron Lauterer]

the follow up changes in 2316ac8bcd19142f8253e13a2a5c427dc6cfac67 look good.
I built pve-cluster with the latest master and tested it with the not 
yet applied patches for the other involved repos in this series on my 
personal production machine.
Going through the summary pages of different resources still worked as 
in my earlier test.
