About Linux software RAID
So, I got this stupid noob question but it's bugging me.
So, I have a ~200GB hard drive
~6GB for Linux OS (xubuntu) files and rest for "other stuff"
The other stuff is on a xfs filesystem, mounted at (root)/stuff/
Now I need to expand my HD space. And I'd need to have the /stuff/ expanded
I can temporarily move the files away from the /stuff/ and format/etc. if needed (BUT NOT FORMAT THE WHOLE OPERATING SYSTEM)
But still, is it possible to use only part of a HDD space on a software RAID setup?
I understand mdadm is used mainly for this thing.
So can mdadm create a RAID (I was thinking of using "linear" aka JBOD mode) that has both normal physical drive/drives and part/parts of a drive?
A PICTURE TO DEMONSTRATE IT (lol great paint skillz)
And the noobie question continues!
So, because my Linux computer is old and ******, it ofc doesn't support SATA nor SATA II hard drives
And buying IDE hard drives now would be kinda stupid - the technology is getting old (I might not be able to use the IDE hdd later on, on newer computers)
That's why I was thinking of getting a cheapish RAID controller (PCI) with SATA connectors. How well does xubuntu handle these?
And would the previous scenario be possible with it?
AGAIN, A GREAT PICTURE TO DEMONSTRATE THIS
If these aren't possible, what would you guys suggest?
And pls don't say "buy a new comp" coz this needs to be as cheap as possible.
THANKS IN ADVANCE FOR EVERYONE WHO HELPS ME (IF ANY LOL)
