Hi, I'm new to Gluster, so please forgive any ignorance on my part. I've tried reading over everything I could find to resolve this myself. I'm having an issue building executables on our gluster volume (there are some other similar issues as well, but we'll deal with this one first). I have the presta infiniband utilities extracted into a directory in my glusterfs volume and I'm attempting to build them. One of the source files, util.c (coincidentally, the first one referenced in the make file) fails to build. I get an error message: Catastrophic error: could not open source file "util.c" Some further investigating reveals the command that causes the issue: icc -I/opt/priv/openmpi-1.4.1/intel-10.1.018/include -pthread -L/opt/priv/mx/lib -L/opt/priv/openmpi-1.4.1/intel-10.1.018/lib -lmpi -lopen-rte -lopen-pal -lmyriexpress -libverbs -lpsm_infinipath -lnuma -ldl -Wl,--export-dynamic -lnsl -lutil -c util.c Catastrophic error: could not open source file "util.c" compilation aborted for util.c (code 4) And further, we see an strace of the command: ... 2717 6601 brk(0x957b000) = 0x957b000 2718 6601 open("util.c", O_RDONLY) = 3 2719 6601 stat64("util.c", {st_mode=S_IFREG|0600, st_size=14370, ...}) = 0 2720 6601 close(3) = 0 2721 6601 fstat64(2, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 1), ...}) = 0 2722 6601 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE| MAP_ANONYMOUS, -1, 0x1000) = 0xfffffffff0bce000 2723 6601 write(2, "Catastrophic error: could not open source file \"util.c\"\n", 56) = 56 2724 6601 write(2, "\n", 1) = 1 2725 6601 exit_group(4) ... We can also see that the file is indeed present: $ ls -l util.c -rw------- 1 brs users 14370 Apr 8 2002 util.c $ stat util.c File: `util.c' Size: 14370 Blocks: 32 IO Block: 4096 regular file Device: 18h/24d Inode: 4295774314 Links: 1 Access: (0600/-rw-------) Uid: (1229806/ brs) Gid: (10001/ users) Access: 2010-01-17 00:27:43.000000000 -0500 Modify: 2002-04-08 21:13:57.000000000 -0400 Change: 2010-01-17 00:27:43.000000000 -0500 If I extract the tar-ball in /tmp, a local ext3 fs, the compile line above works correctly. diff /work/b/brs/presta1.2/util.c /tmp/presta1.2/util.c also appears clean. Any ideas what is happening here? Is there an issue with mmap2() and glusterfs?
