Which file system to choose?

Question

linux

Good afternoon Ol.
I cannot find a file system that satisfies the following conditions: it is

necessary to collect several disks of different types and volumes into one volume
;

The most suitable example is BeyondRAID or Ceph. The first commercial system, the second distributed and the mirror of the blocks - not optimal. You can try zfs raidz. But I think that the piece of iron - the old hp 160 - will not pull on the overhead costs for maintaining zfs.

Answer 1

What are the hardware requirements for zfs? The minimum to just turn on is 512 M of memory and a 32 bit processor. Minimum working - 64 bit processor (eg dual core Atom ( !!!!!!! )) and 1 GB of memory.
Do you have a Xeon server and are you still worried? :)
Feel free to implement, such servers will definitely last a couple of decades, I have one at work, it is already how old, and it is more alive than all the living. Yes, it's like a file washer already, but you don't need it anymore, there's a file storage and all the chiki farts :-D

Answer 2

GlusterFS?

Answer 3

I can not find a file system that satisfies the following conditions: it is
necessary to collect several disks of different types and volumes into one volume. Some
kind of fault tolerance of the file system and data in it is necessary.

What's a good question? To give an exhaustive answer to it, you need to answer another question - "Whose data will be stored there, your personal or business (left uncle-aunt)?"
If personal, then ext4 on the hardware you have will take out.
If this is business data, then the business must provide the equipment corresponding to its Wishlist and then demand something.
