Hey all,

I want to start using btrfs on my san/nas and use that as a backend for my nextCloud. Before I had read up on btrfs I was thinking about using RAID1. I thought RAID1 would fulfill my two requirements:

• It would allow me to just pull out a disk and put in a usb dock and read its contents. (disaster recovery, or for my SO to just power down the server and get her data off if something happens to me).
• It would simply Mirror the data so a single drive can fail and everything is fine.

Now I read things on the documentation of btrfs and in some other places that the RAID1 implementation of btrfs is non-standard, in that is also has some striping functionality.

The image included is from the btrfs docs and it seems it also stripes, not just mirrors, when using 4 disks.

Now my question is: What is its behaviour when using 2 disks? Will this fullfill my two requirements? If not do you have any other recommendations? (I mean i could use zfs...)

A penny for your thoughs :-).

Hey all,

Edit: changed confusing wording based on dack's comment.

I have a problem. I'm building a SAN and I'm playing around with btrfs to learn more about how to use it.

I run into the problem where my sdd1 partition is recognized as swap filesystem. I don't understand whats going on here. I formatted all these drives through my usb-dock via my desktop. All the others are fine, so why is this one giving me problems? I tried removing it with parted amd recreating it as btrfs or ext4 doesnt seem to help.

Does anyone have any insight of why this is happening?

Hey all.

I need some advice on how to deal with the adhoc vs planned work. There are emails, tickets and verbal interruptions that need my attention. Additionally there is an incrr sing amount of meetings I need to attend. At the same time I want to focus on the development of the infrastructure for the planned work. I notice that all the interruptions are detrimental to both the planned and the adhoc work.

The fact that I have to switch my attention all the time and can't just focus starts to frustrate me. It also has to do with my adhd. I cant utilize my hyperfocus to finish the planned work, instead it stimulates the attention switching side of my adhd and cant get into the problem. I just notice I am not as effective as I was before I got this workload.

Do you people recognize this struggle? How do you deal with this?

Hey all,

I would like to get the above certifications. What resources did you use to study? I can't afford the official training and my employer doesn't want to pay for it.

Any and all help, and all tales of your experience is aplriciated.
