Hello @Alvian 


Thanks for raising the question, this error on Linux MA’s could be a few things.

Can you advise the version you are running of OS and Commvault?


Can you also try the following: 


  • Executing the command  ( ./3dnfsd -cn <client anme> -vm <instance>) and confirm the output.
  • If the Output results in the following error it means there is a missing symbolic Link: 

“error while loading shared libraries: cannot open shared object file: No such file or directory”

  • Running command: ln -s /usr/lib64/ /usr/lib64/ creates the symlink


Kind regards
