Re: BTRFS Question

Hi
Tried that but did not quite work.

I get the following only:

[root@xxxxx ~]# btrfs filesystem show yyyyyyyyyyyyyyyyyyyy
Label: 'My_Data'  uuid: yyyyyyyyyyyyyyyyyyyyyy
       Total devices 1 FS bytes used 95.40GiB
       devid    1 size 1.81TiB used 98.04GiB path /dev/sde2

btrfs-progs v4.0

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.

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