I'm using gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-95) which I guess is the reason for those problems. For vgextend/vgreduce gdb told me, that in vg_extend_reduce "vg_name" pointed to 0x1. So i did a little debugging and therefore also inserting the line: int vg_extend ( char *vg_name, pv_t *pv, vg_t *vg) { printf("VG Name is %s\n",vg_name ); // this one return vg_extend_reduce ( vg_name, pv, vg, VG_EXTEND); } in vg_extend_reduce.c, the same in vg_reduce(). Without changing anything else, vgextend and vgreduce work for me now. Similar in lv_extend_reduce.c: int lv_extend ( vg_t *vg, lv_t *lv, char *lv_name) { printf("Extending %s\n", lv_name); // added this line. return lv_extend_reduce ( vg, lv, lv_name, LV_EXTEND); } I don't speak C too fluently, and I don't know if printf() does some implicit casting or something or if it's gcc 2.96, but maybe this information helps a bit in finding the mistake.
