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.

Solved: decided to avoid the funkyness this would invoke and just bought another drive. all good now👍

About a year back, I moved my internal 8tb and 4tb HDDs from my main Windows machine to my old PC-turned-Linux-server. They hold a bunch of bulk data like Youtube channel archives and torrents that are open to download.

I would like to do an in-place ext4 conversion, if possible. Currently I've just started shuffling data off to an SSD and the plan was to slowly shrink the NTFS partitions and turn the new space into ext4, 500gb at a time (size of the intermediary SSD), but it is taking an unbearably long time. Shrinking the 4tb partition in gparted has been running for 13 hours, with an estimated 22 hours remaining! And I'll have to do it 7 more times for the 4tb, and 16 times for the 8tb!!

Is there a better way to do this?

I'm not sure what the chances actually are, but that much rewriting and shuffling data, if it doesn't immediately result in data loss it is going to put a lot of wear on your drives. If your largest drive is 8 TB, I'd look for another 8+ TB drive so that you can copy the data and then reformat. Even a slow external drive is likely to be faster than what you're doing.

Yep, I've just ordered another 8tb to copy to and avoid the headache that could be a drive failure. And it'll certainly be faster, gparted is still giving a 13 hour ETA for the first resize! Thanks for the help!
