IC44058: CLEARCASE:VOBs CAN ONLY BE EXPORTED FOR NON-CLEARCASE ACCESS ONCE ON A LINUX 2.4 SYSTEM YPBINDPROC_DOMAIN: Domain not bound

APAR status

• Closed as Permanent restriction.

Error description

• Linux 2.4 series kernel platforms don't allow a ClearCase NCA
  export <view-tag/vob-tag> to be
  exported if the sob-tag has already been exported with another
  view.
  Ex. Of this entries in  /etc/exports.mvfs
  /view/nca_view1/var/tmp/NCAVOB1 -o dubvar(rw)
  /view/nca_view2/var/tmp/NCAVOB2 -o dubvar(rw)
  /view/nca_view3/var/tmp/NCAVOB3 -o dubvar(rw)
  /view/nca_view1/var/tmp/NCAVOB3 -o dubvar(rw)
  /view/nca_view1/var/tmp/NCAVOB2 -o dubvar(rw)
  /view/nca_view3/var/tmp/NCAVOB1 -o dubvar(rw)
  only the first three are exported and the last three are not.
  
  The error is:
  export_mvfs: Exporting all
  YPBINDPROC_DOMAIN: Domain not bound
  
  
  This is due to a limitation in how the NFS kernel exports
  work in the Linux 2.4 series kernels.
  This cannot be fixed in ClearCase.
  However, the Linux 2.6 series kernels will work with multiple
  views
  exporting the same VOB.
  Support is currently available for  SLES9 which has a
  2.6.5-based kernel.
  SLES9 SP1 includes fixed support for the "fsid=" flag.
  

Local fix

• Upgrade to a 2.6.5 kernel or
  only put one /view/vob entry per vob in the
  exports file.
  

Problem summary

• ClearCase running on the Linux 2.4 kernel only allows export of
  one view per VOB.
  

Problem conclusion

• This bug cannot be fixed in ClearCase; it is a limitation, in
  the Linux 2.4 kernel, on how NFS exports work.
  

Temporary fix
