fstrim does not work with new ntfs driver

[Irre]

Kernel: 5.15.8-gentoo-x86_64
util-linux: 2.37.2-r1

mount -v | grep /sda11

Code: Select all

type ntfs3 (rw,noatime,uid=0,gid=0,iocharset=utf8,discard,prealloc)

fstrim -v /sda11

Code: Select all

fstrim: /sda11: the discard operation is not supported

Irre,

How is /sda11 connected?

It it really /dev/sda11 or it it mounted an /sda11 in the filesystem tree, or even both?

1st off, you're already mounting with discard, why do you care about trying to manually run fstrim?

2ndly, as Neddy asked is /sda11 a mount point, because that's what fstrim works on.

/dev/sda11 is mounted as /sda11 in fstab

fstrim -v /sda11 -- worked as expected with the ntfs3g driver

I get the same error also without discard option.

There are some (reported) problems with ntfs3 (not 3g) and fstrim, though discard (by itself) is supposed to work.
There are timers you can apply telling discard when to run.
