Arch kernel has LDM support?

Just a quick question: does the default Arch kernel support windows dynamic disks?  I believe the driver (or module or whatever) needed for this is 'LDM' .

I have a windows server that is aching to be converted to Arch, just need to make sure I can mount my media volume (spanned across two disks) if I do.

Cheers!

Re: Arch kernel has LDM support?

http://www.mjmwired.net/kernel/Documentation/ldm.txt says that LDM is enabled via the option CONFIG_LDM_PARTITION.

So, we do 'zcat /proc/config.gz | grep CONFIG_LDM_PARTITION'

and we get "# CONFIG_LDM_PARTITION is not set". This probably means no, but maybe yes. Try and see. If it doesn't work, the solution is trivial: edit the config (or config.x86_64) file of the kernel26 package in ABS so that line says "CONFIG_LDM_PARTITION=y", and 'makepkg -s' to make a new kernel package that can be installed with 'pacman -U nameofpackage'. You can even use tools like customizepkg to do this automatically in the future.

I would switch that Winblows technology for good old LVM, though

Definitely no.
