RAID array filesystem recommendations in c/selfhosted@lemmy.world

Do you need to do some maintenance to keep the data in the array intact?

I read of some btrfs scrub commands and md checks and such, but I am unsure how often to do them, and what they actually do.

Thanks for the info!

Could you elaborate on btrfs on top of md raid?

This one seems the most likely solution for me.

Powerloss might happen as I don't have a ups.

And when it comes to mdadm, it just happens to be the first and only redundancy tool I know. I am however open to learn and try new things.

ZFS seems interesting, but: I read that ZFS would require quite a lot of RAM, and I was going for 32 GBs only, would it be enough?

What are the advantages of this over mdadm raid and bcache?

Are there some advantages of btrfs over raid? I understand how raid works but btrfs for redundancy is foreign to me.

RAID array filesystem recommendations (sopuli.xyz)
 

I am planning on creating a home server with either 2 (RAID1) or 3 (RAID5) HDDs as bulk storage and 1 SSD as bcache.

The question is, what file system should I use for the HDDs? I am thinking of ext4 or xfs, as I heard btrfs is not recommended for my use case for some reason.

Do you all have some advice to give on what file system to use, as well as some other tips?

R on Debian (sopuli.xyz)
 

I am thinking of moving to linux (Debian seemed to suite me) from Windows. I have used lubuntu and and ubuntu somewhat before, but their use has been very limited.

My main use would be to do statistical programming on R and Python. Does Debian have all the CRAN packages I can install on Windows? What about packages on Python? Does Debian suite me at all or should I look elsewhere?
