filesystem statistics error -- cannot parse device '/dev/mirror/gm0p2'

Issue #672 resolved

created an issue

I have monit 5.24 and FreeBSD 11.1 and get this:

Oct  4 10:37:12 server4 monit[90215]: filesystem statistics error -- cannot parse device '/dev/mirror/gm0p2'
Oct  4 10:37:12 server4 monit[90215]: filesystem statistics error -- cannot parse device '/dev/mirror/gm0p4'
Oct  4 10:37:12 server4 monit[90215]: filesystem statistics error -- cannot parse device '/dev/mirror/gm0p5'
Oct  4 10:37:12 server4 monit[90215]: filesystem statistics error -- cannot parse device '/dev/mirror/gm0p6'
Oct  4 10:37:12 server4 monit[90215]: filesystem statistics error -- cannot parse device '/dev/mirror/gm0p7'
Oct  4 10:37:12 server4 monit[90215]: filesystem statistics error -- cannot parse device '/dev/mirror/gm0p8'

I think the issue started with monit 5.24 and possible related to https://bitbucket.org/tildeslash/monit/issues/666

    Monit 5.24.0 finds the PART and parent disk with no problem.

    Please can you send output of sysctl kern.geom.conftxt from your system?

    thanks for data, the problem should be fixed, please can you test the development snapshot?:

    wget https://bitbucket.org/tildeslash/monit/get/master.tar.gz
    tar -xzf master.tar.gz
    cd tildeslash*
    ./bootstrap
    ./configure
    make

    Thanks for your help. It works.

    As I use freebsd ports I want to avoid custom installation. So I did:

    cd /usr/ports/sysutils/monit
    make deinstall
    make fetch extract
    cd work/monit-5.24.0/src/device
    fetch https://bitbucket.org/tildeslash/monit/raw/b3ebff6bacb8c31c50b671920a8ff96a55a3b5ee/src/device/sysdep_FREEBSD.c
    cd /usr/ports/sysutils/monit
    make install
