load module from the system module area.
To load a module from a filesystem path, the module name must contain at
least on path separator character (/), to load a module from the system
module areas, the name must not contain a path separator character:
modload ./mymod.kmod # loads mymod.kmod from the curren directory
modload mymod # loads mymod.kmod from the system module area

of these really ancient partitions and you're about to run disklabel, you
can easily run fdisk first and change the partition type to NetBSD.)
As it stands, the code will munch FreeBSD installs under some
circumstances, which is really not acceptable behavior.
The code, along with the kernel support that's been disabled by

sysinst, should prboably be removed entirely after -6 is branched.

I plan to replace gpl2 licensed dmsetup command with our dmctl tool in near

With libdm in tree we can now write RUMP atf test suite for dm driver to
ensure LVM subsystem stability as time goes.

that while modstat and modunload and builtin modules work exactly
the same as in the host case, modload loads file system kernel
modules from the rump kernel namespace. By default, archs which
have rump support for the kernel kernel ABI have the host module
directory mapped into the rump kernel namespace at the same location
(/stand/...). Therefore, if the *host* module directory is populated,
"rump.modload foo" will work as expected. Otherwise, RUMP_MODULEBASE
can be used to point to the module directory.

The server must of course have some disks configured. Let's say
we have this simple server with disks as a few sparse host files:
main()
{
rump_init();
rump_pub_etfs_register("/disk1", "./disk1.img", RUMP_ETFS_BLK);
rump_pub_etfs_register("/disk2", "./disk2.img", RUMP_ETFS_BLK);
rump_pub_etfs_register("/disk3", "./disk3.img", RUMP_ETFS_BLK);
rump_pub_etfs_register("/disk4", "./disk4.img", RUMP_ETFS_BLK);
pause();
}
And we run the server:
mainbus0 (root)
Kernelized RAIDframe activated
/disk1: hostpath ./disk1.img (97 GB)
/disk2: hostpath ./disk2.img (97 GB)
/disk3: hostpath ./disk3.img (97 GB)
/disk4: hostpath ./disk4.img (97 GB)
We can then configure the raid against the server:
> ./raidctl -c theraid.conf raid0
And lo, we have evidence of a level1 raid in the server dmesg:
raid0: RAID Level 1
raid0: Components: /disk1 /disk2 /disk3 /disk4
raid0: Total Sectors: 409599744 (199999 MB)
