ReaR: cannot create rescue ISO when using the NetBackup method

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux (RHEL) 7.6
  • rear-2.4-2
  • netbackup

Issue

  • When using the NetBackup method BACKUP=NBU, ReaR prints error messages then fails
    /usr/lib/udev/rename_device requires additional libraries
        libglib-2.0.so.0 => not found
    /usr/lib/udev/udev-kvm-check requires additional libraries
        libglib-2.0.so.0 => not found
    /usr/openv/netbackup/bin/goodies/bpconverttouch requires additional libraries (fatal error)
        libstdc++.so.6 => not found
        [...]
    /usr/openv/netbackup/bin/goodies/support/versioninfo requires additional libraries (fatal error)
        libstdc++.so.6 => not found
        [...]
    [...]

Resolution

Update to rear-2.4-7.el7 shipped with Advisory RHBA-2019:2273 or newer.

Root Cause

Two issues can be seen:

  1. ReaR doesn't include standard libraries due to already finding it in the NetBackup path /usr/openv

  2. ReaR includes too many NetBackup binaries from /usr/openv making ReaR's ISO verification fail
