Disklabel can not label slices. For a project I had to work on receently
I hacked up a slicelabel tool that used libdisk (which can handle slices)
to initialize the disklabels in slices. The code for the slicelabel
command is quite short:
#include <sys/types.h>
#include <libdisk.h>
#include <paths.h>
#include <stdio.h>
#include <string.h>
static void usage(void);
static void label_disk(const char *name);
static void
usage(void)
{
fprintf(stderr, "Usage: slicelabel disk [disk ...]\n");
exit(1);
}
static void
label_disk(const char *name)
{
struct disk *disk;
if ((disk = Open_Disk(name)) == NULL)
fprintf(stderr, "Unable to open disk %s.\n", name);
else
Write_Disk(disk);
}
int
main(int argc, char *argv[])
{
int index;
if (argc == 1)
usage();
for(index = 1; index < argc; index++)
label_disk(argv[index]);
return(0);
}
