I did a thing, have a quick Linux question

@Sparkum said in I did a thing, have a quick Linux question:
Are you able to group harddrives in a non raid format with linux?
Like a stablebit drive pool for linux kind of thing?
Versus making raid 0
I know that you're asking @dafyre but just use ZFS. Software raid on Linux in the modern world has very little overhead.

Why would you do this, when you could use MD Raid and have a highly resilient solution?

I've got my important media and my "who the heck cares" media.

the Who the heck media you could still put onto RAID0 array.

I'd rather lose 1 disk and 2TB versus lose 1 disk and 6TB

You raid 0 for speed
-
RAID0 would give you a lot of read/write performance while not caring if you lose a drive (as the data is gone anyways)

How many TB do you have that you can't lose?

I don't get this concept...
RAID0 you'd lose it all, no RAID you'd have no "protection" of a drive failing either.
So unless you mean to mirror the drives in a separate mechanism for protection, while not getting any benefit of RAID, you have a backup.
-
I'd say 8-10TB

and how much total? Also how quickly are you going to expand?
-
Well what are we talking here, for me it would be (atleast) 3 2TB drives, so you are saying make 1 giant 6TB raid 0 correct?
So 1 drive dies I lose 6TB
Or are you saying make 3 2TB Raid 0's so that if I lose 1 I only lose 2TB
Can I then make it appear to be one disk though?And please keep in mind there might just not be a linux thing I dont know.
For example in Windows I have stablebit drive pool pooling my drives so that if I lose 1 drive I only lose the data on that one drive.
-
Total (used and unused) I'm sitting at 22TB.
And I'd say I'm expanding fast enough that I felt I needed 22TB, have 6TB free, had prob 12TB+ free 6 months ago.
Offloading some junk to the cloud though currently.

My thought was if you have 2TB you can't lose out of 10, put everything in a raid 0 and then buy a small NAS backup for the 2 TB.

I'm just trying to understand what you are trying to do.
Without RAID, you won't be able to present multiple disks to any OS (unless it's FakeRAID and Windows) and show it as one drive.
-
My initial question was, is there a way to group harddrives in a non raid format. So yes, a fakeraid

There is, and FakeRAID is about as useful as RAID0 (if you want to protect the data).
Simply don't use it.
-
And maybe this is just me going from Windows to Linux, I admittedly don't know anything about how harddrives work in Linux
-
I'd do RAID1, or RAID 6... I've only got ~3TB of data, but only 2 x 3TB drives (one of them is my backup drive at the moment).
If I don't have a real RAID controller, I'd use mdadm for Linux. I've used it in the past, and it worked very well.
