Hi
I am just learning about btrfs on my home system.
How do I know what kind of options where used to create a BTRFS filesystem?
I installed F21 from scratch and I created a BTRFS filesystem on a HDD. I think I created it with the "single" option.
Now I read that that is dangerous, I should have created it as one of the raids if I want to have data redundancy and protection vs bit rot (which is what I was looking forward to).
How can I verify it? Also, If I want to change it, can I do it IN-PLACE or do I have to reformat/recreate the filesystem?
Thanks for whatever help/illumination you might provide. I am catching up on btrfs, but I am not there yet.
