From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Migrating Linux install from old SSD to new SSD with different filesystem (dandroid.app)

submitted 1 year ago by [email protected] to c/[email protected]

Hi all,

I currently have a Linux install from an old 256GB SATA SSD that I inherited. It was originally used as a swap drive in another person's RAID server for about 7 years, then it was given to me, where I put my own Linux install that I have been running for about 5 years.

About a year ago, I acquired a new computer that has an NVMe SSD. It originally ran windows, but I dropped in my SSD with my Linux install, installed grub on the NVMe SSD, and booted to the old SSD.

I am mildly concerned about with this SSD being so old, it could crap out on me eventually. I remember that being a topic of discussion when SSDs first hit the market (i.e. when the one that I am using was made). So I was thinking of wiping the 1TB NVMe SSD that is currently unused in this computer and migrating my install to it. Now, I know I could copy my whole disk with dd, then expand the partition to make use of the space. But I was wondering if I could change the filesystem to something that had snapshots (such as btrfs).

Is it possible to do this, or to change filesystems do I need to create a new Linux install and copy all the files over that I want to keep?

-x (alias --one-file-system) means "don't cross filesystem boundaries"; is that what you meant? Or did you mean -X | --xattrs?

Edited because I wrote some things before that were incorrect.

Yep, that's so you don't end up potentially copying /dev, /sys, /run or any other mounted partitions.
