Error description

  • alt_disk_mksysb fails to convert JFS to J2
    filesystems if the current rootvg has J2
    filesystems only.
    
    alt_disk_mksysb verbose output looks like:
    [...]
    Source boot disk is: hdisk1
    0: No mounted filesystems of type jfs.
    0: No mounted filesystems of type jfs.
    
    0: Cleaning up.
    0: Successfully completed converting image.data to
    jfs2
    0505-121 alt_disk_install: Error.
    [...]
    

Local fix

  • Restore the mksysb and then use alt_disk_copy for
    the JFS to J2 conversion.
    
    Or skip the space checking (-S) option.
    But ensure we have enough space for the mksysb,
    specially as J2 needs more space for the meta data
    than JFS does.
    

Problem summary

  • Failing error executing alt_disk_mksysb -T:
    
    Source boot disk is: hdisk1
    0: No mounted filesystems of type jfs.
    0: No mounted filesystems of type jfs.
    
    0: Cleaning up.
    0: Successfully completed converting image.data to
    jfs2
    0505-121 alt_disk_install: Error.
    

Problem conclusion

  • The fix is to add a test in jfs2j2 check_space() function to
    not calculate j2 inode size requirements when using a mksysb
    image.
