APAR status

  • Closed as program error.

Error description

  • If a non-root user tries to copy file in a relative path,
where root is mapped to nobody, rcp fails.

$ pwd
/mygpfs/rsimon_files/c
$ rcp afile <hostname>:/tmp/bfile
rcp: /afile: No such file or directory

This happens in a case of gpfs/nfs mounted filesystem
where root squashing is enabled ie mapped to nobody.

Using absolute path works fine.
$ rcp /mygpfs/rsimon_files/c/afile <hostname>:/tmp/afile

Local fix

  • Use absolute path:

> pwd
/mygpfs/rsimon_files/c
> rcp /mygpfs/rsimon_files/c/afile <hostname>:/tmp/afile

Problem summary

  • If a non-root user tries to copy file in a relative path,
where root is mapped to nobody, rcp fails.

$ pwd
/mygpfs/rsimon_files/c
$ rcp afile <hostname>:/tmp/bfile
rcp: /afile: No such file or directory

Using absolute path in rcp command works fine.

Problem conclusion

  • When user tries to copy a file in the relative path,
the path name is expanded with correct current working
directory. This causes rcp to find the file and resolves
the problem.

Temporary fix
