#852 PR merged: Solving Multipath cannot load due to libaio missing in ramdisk

Labels: bug

When I boot on rear rescue (tested via grub menu) , I can't use multipath because libaio is missing in the ramdisk.

Here is my proposition for modification:

  • Correct LIB variable name to LIBS
  • Changing ${PROGS[@]} to ${LIBS[@]}
  • Using a local variable to find the directory where libaio is located (can be different depending to the Linux distro and arch; for example /lib/powerpc64le-linux-gnu/libaio.so.1 for ubuntu 16-04 ppc64le).

@gdha, you are right. I proposed the following:

  • Using sort -u to filter duplicate DIR
  • Create a VAR with concatenate DIR/libaio(if several different PATH has to be added)
    for libdir in $(ldconfig -p | awk '/libaio.so/ { print $NF }' | xargs -n1 dirname | sort -u); do
        libaio2add="$libaio2add $libdir/libaio*"
    LIBS=( "${LIBS[@]}" $libaio2add )

Your feedback are welcome.
