Thanks for your reply! Very helpful. The image I grabbed from the offial docs here: https://btrfs.readthedocs.io/en/latest/mkfs.btrfs.html#mkfs-section-profiles

I’ll do some testing with raid 1 to see if it behaves as I expect. The only way to be properly sure i guess.

Hey thanks! Thats it. mkfs.btrfs fixed it. Its weitd though that the other disks were recognized correctly.

Now I can go and experiment with raid setups

Ah my apologies, I used the word formatted incorrectly. I use parted to do: ‘’’ Rm 1 Mkpart primary btrfs 1 3,6T ‘’’

Parted then shows the btrfs filesystem. If I then quit and look at ‘lsblk -fs’ it shows me the table in my post. I think I do this right. Im going to remove the disk and see how it behaves on another pc.

Thanks, however language by its very nature is dynamic and changing. If enough people use adhoc in this way it will mean spontaneous ;-).

Care to try and answer my question?

Hey thanks for the rant! Very informative. I agree that one should know the fundamentals and not just focus on the cert. I need the cert for my career though. As I always say: Certs are for managers. Any half decent technical knowledgable interviewer will suss out if you know your stuff.

I’m doing microtik training in the autumn to get my network knowledge up. (Why do cisco if networks have standardization). I need the study guides or other resources because they ask about commands I rarely use, or if I use them its only one or two specific commands (i.e. i use ip addr but rarely ip link or ip netns. But having the RHCSA/E checkmarks next to your name does wonders for your marketability. ($€₱£¥ ;-))

I’ll drop you a dm for that copy.

Thanks for the advice. I’ll check those out :-).
