I had read that you can use lvm to “merge” 2 drives (hard) togather so that they can be used as one big drive. How would one go about creating a larger drive with mismatched sizes in manjaro architect
My hard drives are a 2tb barracuda and a 500gb Toshiba drive.
To sum it up in th end i would like a 2.5 tn drive to install manjaro on
Something like this is what you are asking for, just be aware that if you do this and one of the disks dies it’s probably bye bye data.
If data integrity is of some import you probably want lvm on top of raid.
If you do like in marelooke’s suggested link, the drives will not be in RAID. The space on all drives will be used as if it was one larger drive with all the individual drives as smaller pieces of the big logical drive. That is the difference in LVM between Physical Volumes (the actual hard drive) and Logical Volumes (what the OS sees as a drive).
So yeah you can use any number of drives of any size like that, since it does not have to read in stripes or chunks.

Thanks for your inputs
My suggestion would be (if you can avoid it) to never run JBOD (which is what this essentially creates) and use them as seperate drives, with symlinks for directories to present the space as being under the same “tree”.
That way, you’ll only lose the data on the failed drive, in the case of a disk failure.
If you can’t avoid it (because you need all of the space to be in the same folder), then that’s unfortunate, but if you can… avoid
