Do they get along well? Will I have to disable COW on postoffice and domain subvolume? Anyone here with experience in this matter? I am planning to upgrade my current setup which is GW2012SP4 running on SLES11SP4 to GW2014R2. I like the snapshot feature that btrfs has but I do not know if it will worth it only for that.

Another question I had is what differences are between GW2014SP2 and GW2014R2?

Best Regards,
