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

Try "man btrfs-filesystem" for details, but "btrfs-filesystem show"<br>
as root should show the specs for all btrfs filesystems on your machine.<br>
