Error description

  • In AIX 7.1.2, a native wpar can be made with mkwpar using
a mksysb file. An error occurs when the mksysb file is
used
as a backup device in the command:

1. mksysb -i /jworkfs/mksysb.71-02-02.small
   Create a mksysb from the running system. No problem.

2. mkwpar -l -t -B /jworkfs/mksysb.71-02-02.small -g
datavg1 -n wpar1

Says:
mkwpar: Extracting file system information from backup...
mkwpar: 0960-355 Non-shared /usr and /opt file systems
must be mounted read-write.

And mkwpar fails here. The problem is reproducible.

A straight mkwpar in the system works though, with same
datavg, so the problem is when using the mksysb image:

# mkwpar -l -t -g datavg1 -n wpar1   --- This works.

Problem summary

Problem conclusion


    

  • Added suitable check in wpar code such that mkwpar command
should not fail before mksysb process actual File system
information.
