Alright. All in due time. It is not that I have gazillions of such large
files laying around or even the amount of storage capacity available. I
intend to format an external 4TB NVME SSD with encrypted BCacheFS. And for
testing copy over 1 TB of data from an external 2TB NVME SSD to it and see
how that goes.
I am happy that BCacheFS went into the mainline kernel and I rather see
things done right than fast.
Have a Happy New Year.
Best,
