I used ddrescue when I cloned my defective harddisk. There were several errors I wasnt aware of, but it worked

An interesting option is Xen. https://wiki.gentoo.org/wiki/Xen

An other option is to start with a simpler boot loader, lilo. Create an ext2 partition and place /boot there.

Why not temporary remove the world file. Then update your system. Then restore your world file, possibly in small steps.

Grub2win is a grub2 boot loader that is installed and administered via windows. Good if you want to multiboot several systems without annoying windows!

I get the same error also without discard option.

How is /sda11 connected?

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

/dev/sda11 is mounted as /sda11 in fstab

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

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

mount -v | grep /sda11 fstrim -v /sda11

When I replaced hdd, I simply did i full image backup. Removed hdd and installed ssd, restored from image backup. Last partition was expanded to fill the size of the new ssd. These step were run on linux on an external usb-stick. All systems, Windows inclusive, were succesfully moved to the new ssd ...

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

Thank you. Now it works

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.
stab.
Neddy and others will perhaps recommend device id using something other than /dev/sda2 ...

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

This works, but -t ntfs3, must be written:
mount -t ntfs3 /dev/sda2 /tmp1
mount -v ...

You have no "mount" command, but you can specify ntfs3 in /etc/fstab

cat /etc/fstab | grep ntfs3
/dev/sda2 /tmp2 ntfs3 noauto,prealloc,noatime,rw 0 0

mount /tmp2

mount -v | grep ntfs3
/dev/sda2 on /tmp2 type ntfs3 (rw,noatime,uid=0,gid=0,iocharset=utf8,prealloc)

Well, comparing apples and oranges, because ntfs-3g runs in user mode (FUSE, file system in user mode) and ntfs3 runs in kernel mode. Naturally a file system driver is faster in-kernel...

But is ntfs3 as compatible as ntfs-3g is in a real life scenario?
Ntfs3 is much better! I tested to write 800 ...

But it's still a huge difference! Is a filesystem driver in userspace so much slower?

Yes ntfs3 seems to be almost 4 times faster than ntfs-3g!

No, 2 GB in 5 s!

I have built 5.15.0-rc6 with ntfs3 support. We have no mount command for ntfs3 but /etc/fstab "works":

I run this script to clean the world: for i in `cat /var/lib/portage/world`

I think it is! Without busybox my system has no network!

Edit, emerge --info emerge --info:

RPI4, After update + depclean, busybox disappeared and no network started after that

emerge busybox, solved the problem...

I'm trying compile gcc and I get

I thought it meant space in /vat/tmp/portage so I mounted big enough space to it (hundreds of GiB)

So question is where does ...

Do you think grub2win might help that or is it just another way for the bootloader to see both OS's but from the Windows side?
grub2win loads grub via the windows bootloader, I think. I tested it under Virtual Box. It worked fine. I got a menu where I could choose between Windows10 and a Linux ...
