[ibp] fa_build_image fails on resize2fs command

[Sylwester Brzeczkowski]

fa_build_image fails on resize2fs command with '-F' option.

I'm running it using a command:
sudo fa_build_image --image_build_dir /tmp/ibp3 --log-file fuel-agent-log.log -d --data_driver nailgun_build_image --input_data_file prov.json

When I tried to reproduce it manually, the same error appeared:

vagrant@solar-dev:/tmp/ibp3$ sudo resize2fs -F -M test2
resize2fs 1.42.9 (4-Feb-2014)
resize2fs: Unknown code ____ 255 while trying to flush test2

In fact it worked without '-F' flag which I think is unnecessary here.

I was working on Ubuntu 14.04 (vagrant)

-F option does not seem to be necessary here. resize2fs man says
"-F Flush the filesystem device's buffer caches before beginning. Only really useful for doing resize2fs time trials."

please try to remove this option from fuel-agent and run again. If it works, we probably need to remove it.

    [IBP] remove '-F' flag from resize2fs command

    '-F' flag is unnecessary and causes failures in case of
    using vagrant environment.
