We use 64-bit RHEL 5.8, kernel 2.6.18-308.11.1.el5. We want to put Oracle installation files on a shared NFS server. But runInstaller always fails with "Error in writing to directory /tmp/OraInstall..." message, even though /tmp has space and the said subdirectory can be written to. We *can* run OUI successfully if we copy the installation files to a local filesystem.

The message is catch-all (according to one Oracle note). So we suspect some mount options are not up to Oracle's standard. We tried different ones, mainly "rw,bg,nointr,hard,timeo=600,wsize=32768,rsize=32768,nfsvers=3,tcp" and that plus "noac" (based on Note:553283.1). The error does not change. An strace is done as follows:

• BEGIN ----------- $ strace -o /tmp/abcd -f ./runInstaller -ignoreSysPrereqs

  ---

Please run the script rootpre.sh as root on all machines/nodes. The script can be found at the toplevel of the CD or stage-area. Once you have run the script, please type Y to proceed

Answer 'y' if root has run 'rootpre.sh' so you can proceed with Oracle Clusterware installation. Answer 'n' to abort installation and then ask root to run 'rootpre.sh'.

---

Has 'rootpre.sh' been run by root? [y/n] (n) y

----------- END ----------- The strace output near the error has these lines:

25078 dup(2)                            = 5
25078 fcntl64(5, F_GETFL)               = 0x8002 (flags O_RDWR|O_LARGEFILE)

25078 fstat64(5, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0 25078 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xfffffffff7f70000 25078 _llseek(5, 0, 0xff8f0ac0, SEEK_CUR) = -1 ESPIPE (Illegal seek) ...

25078 write(5, "\n", 1)                 = 1

25078 write(5, "Error in writing to directory /t"..., 181) = 181 25078 write(5, ": Invalid argument\n", 19) = 19

Apparently, stderr (file descriptor 2), duplicated to descriptor 5, goes through a seek. It's not even seekable as far as I know.

Any input is appreciated. It's not a big issue. Just something nice to have.
