Hi all, I have a cluster of 3 nodes, 18 OSDs. I used the pgcalc to give a suggested number of PGs - here was my list:
Group1 3 rep 18 OSDs 30% data 512PGs Group2 3 rep 18 OSDs 30% data 512PGs Group3 3 rep 18 OSDs 30% data 512PGs Group4 2 rep 18 OSDs 5% data 256PGs Group5 2 rep 18 OSDs 5% data 256PGs My estimated growth is to 27-36 OSDs within the next 18 months, after that probably pretty stagnant for the next several years. Thoughts? -Tony
