I just finished installing Ubuntu Server 26 on my new 20 TB hard drive and transferring the files from my old 8 TB drive to this one (I was using Ubuntu Server 22). After I got everything working, my hard drive kept making noises while I wasn't doing anything. This command told me it was ext4lazyinit that was constantly accessing the hard drive : sudo blktrace -d /dev/sda -o - | blkparse -i - ext4lazyinit apparently zeroes-out stuff on the drive or something. I made this command line to make it go way faster (and that got rid of the noise) : sudo mount -o remount,defaults,init_itable=0 / "init_itable" says how many milliseconds ext4lazyinit should wait between doing work. "0" means "always work".
