[solved]linux 5.15 and new ntfs driver

[Irre]

I have configured the kernel only to use the new ntfs3 driver. It works excellent, but how do I tell "mount" to use this new driver by default?

Code: Select all

mount /dev/sda2 /tmp1
mount: /tmp1: unknown filesystem type 'ntfs'  

This works, but -t ntfs3, must be written:

Code: Select all

mount -t ntfs3 /dev/sda2 /tmp1
mount -v | grep /dev/sda2
/dev/sda2 on /tmp1 type ntfs3 (rw,relatime,uid=0,gid=0,iocharset=utf8)

Put a line in your /etc/fstab file, specify ntfs3 as filesystem type, and you should be good to go.

A benefit of this is no need to list the device on the command line, because fstab has that information.

Neddy and others will perhaps recommend device id using something other than /dev/sda2, such as partition or filesystem UUID, as the device identifier. This is sound advice in the general case, but your system may be stable at assigning /dev/sda2 the way you expect.

Yes specifying ntfs3 in /etc/fstab works fine. But I want it to be default when I use mount for any (eg external usb disk) ntfs not specified in fstab.

Maybe an entry in /etc/filesystems will take care of things.

I take it you are trying to avoid only the "-t ntfs3" part of the `mount` command line.

Thank you. Now it works

I added an entry ntfs3 in /etc/filesystems, but I still can't mount a ntfs file system with sudo mount -t auto /dev/xxx /mnt or sudo mount /dev/xxx /mnt, the error message is:

mount: /mnt: unknown filesystem type 'ntfs'.

But if I run sudo mount -t ntfs3 /dev/xxx /mnt, it works.

How did you make it work?

My /etc/filesystems is as below:

Code: Select all

# /etc/filesystems
#
# This file defines the filesystems search order used by a
# 'mount -t auto' command.
#

# Uncomment the following line if your modular kernel has vfat
# support and you want mount to try vfat.
#vfat
ntfs3

# Keep the last '*' intact as it directs mount to use the
# filesystems list available at /proc/filesystems also.
# Don't remove it unless you REALLY know what you are doing!

/etc/filesystems is only needed when you have some fs-modules in your kernel built as module. If you have for example vfat static built in your kernel then it is not needed to activate it in etc/filesystems for finding it with "-t auto" (I have vfat static in my kernel + never touched /etc/filesystems => "-t auto" works for all my preconfigured lines in /etc/fstab).
