Invalid Oracle Cluster Registry (OCR) location.

Symptom:

 We clone grid home (CRS)  from other node .Details see oracle support Doc ID 1493677.1
  Try to reconfigure GI home with new nodes. We always get below error

 ./config.sh -debug -logLEvel finest 2>&1 | tee `hostname -s`.Grid_config.log

[INS-41321] Invalid Oracle Cluster Registry (OCR) location

Diagnose:

   Compare ZFS mount options with good ones. No luck.
   Compare ZFS shares on filer side with good ones.No luck.
   Modify OS privilege, chmod.....etc .No luck.

Solution:

   Finally we found the OS kernel version of the source GI home is different from the target
2.6.39-400.298.2.el6uek.x86_64 vs 3.8.13-118.20.2.el6uek.x86_64

  The clone files must be from same kernel level source home
