Nowadays it's even reasonably (but not entirely) portable: struct statfs has a f_fsid member. The magic number for Lustre is "#define LL_SUPER_MAGIC 0x0BD00BD0" (defined in lustre_user.h). The magic number for GPFS is ... 0x47504653 I guess? On Darwin, the f_fsid is a short, so these magic numbers might get truncated. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
