NTFS-3G automount with big_writes

Hi!

I've got a problem in locating place where I can set default options for mounting NTFS partitions (mostly - USB drives). I've been researching through the internet and found that NTFS-3G supports `big_writes` mount option which implies writing in larger parts instead of default 4kB. As I'm using my drives to carry large files without this option means really high cpu usage causing desktop to become unresponsive.

How can I overcome this situation? I was thinking about udev rule, but honestly - I don't know how I can specify that I want to handle only NTFS partitions. Maybe it is wise to use it by default in Arch?

Thanks!

Re: NTFS-3G automount with big_writes

I imagine that could be set in your automounter's configuration - but what are you using for automounting?

Re: NTFS-3G automount with big_writes

For what I'm seeing in htop - there is helper `udisks2`. I used what comes with Gnome, nothing changed. As far as I can see in Wiki - there is something that can replace it - Udev Automounting udisks wrappers, but I don't know what I should use as nothing is recommended.

Re: NTFS-3G automount with big_writes

Is big_writes an option you pass to mount/fstab? You can try udevil and customize the mount options for ntfs in /etc/udevil/udevil.conf.

Re: NTFS-3G automount with big_writes

@anonymous_user - yes it is. Currently I have to umount and mount again ntfs partition with -o big_writes (as remount is not supported). I'll try it, thanks a lot!

BTW. This option really decreases CPU usage when writing to ntfs filesystem. On my system (C2D T8300) it dropped from around 15% to ~1%!

EDIT: I'm not sure how I should replace udisks2 with udevil - I've installed the latter, but Gnome still seems to be automounting via udisks2. When I wanted to remove udisks2 - pacman warned me that dependencies will not be satisfied, so the package cannot be removed. Any ideas?
