well, I have 1PB of capacity for data disks and 3TB of capacity for metadata
(SSD).
With 512B inodes, this ration seemed to be quite ok, while with 4k inodes,
I run out of free space on SSD pretty fast. So I'm thinking about re-creating
file system with smaller inode size.
I don't think I will ever need encryption keys.
