I’m a new Linux user, I’ve an SSD and using BTRFS File System.
I saw this post : "PSA: Linux 5.16 has major regression in btrfs causing extreme IO load" - #74 by ajgringo619
But I don’t know the exact steps on how to properly edit the fstab file, I did this :
sudo mount -o remount,noautodefrag /
sudo nano /etc/fstab
Changed autodefrag to noautodefrag in every subvolume.
And rebooted the machine. But the btrfs-transaction process is still writing 2MB per second on the disk.
Can anyone please tell me the exact steps to edit the fstab file ?

That should be all you need.

I’m not sure if I followed the right steps because “btrfs-transacti” is still running.

You have a btrfs system so btrfs-transactions should still be occurring…

OK, but can you tell me if these steps are right ?
sudo mount -o remount,noautodefrag /
sudo nano /etc/fstab
Changed autodefrag to noautodefrag in every subvolume.
Reboot

That should be fine.
You can verify it with findmnt -ln | grep btrfs
