So I'm about to go home and set up a btrfs mirror for my data.
To cut a long story short, (and since Zebra doesn't stop by here anymore :P) I'm not compelled to use ZFS, I also have only 2GB of ECC ram, so I dont want to have critical dismounts.
I wanted a COW filesystem. I wanted 'BitRot' protection.
Is anyone onboard with BTRFS?
I intend to simply take pairs of drives, and make mirrors.
I will then merge the mirrors using MergerFS (if I need to).
I will then use my 3X 1.5TB drives (they're older) as a triple parity RAID1, for my desktop backups (media will be on the single parity raid1's).
Am I correct in understanding that the RAID functions are all... invisible... to the end user (me)?
So basically; If i was to:
mkfs.btrfs -d raid1 /dev/sdb /dev/sdc /dev/sdd
Then all I have to do is mount EITHER, sdb, sdc, or sdd, and the RAID features are AUTOMATIC?
Repeating, I only need to MOUNT a SINGLE drive, and it JUST WORKS?
Is there a way to CONFIRM this to match my levels of paranoia?
Also, assuming I'm correct above.
Can I easily see which drives are paired with each other?
Last thing I want is to have sda,b,c,d,e,f,g,h,i,j,k,l,m,n; and have to manually remember which one went with which pair.
Expect MANY questions later on.
For some background, I was using OpenMediaVault and Snapraid, but I got nervoud after snapraid reported false metadata problems and rSync failed and required command line intervention.
Ive now decided, I like a GUI too much (to physically see a folder layout) to work from a web-gui, or a command line alone.
As such, I'll be installing a full install of Ubuntu Desktop LTS, and going from there.
HDD space is not a concern on the boot drive. It has a dedicated 320GB laptop HDD to do that.
I just got sick of trying to configure from 'web interfaces' which break so easily.
