While MMP is not particularly useful for desktop systems, it is a very useful feature for HA servers. While HA software such a pacemaker is supposed to prevent starting resources (e.g. mounts) several times, there can come situations where this does not work perfectly. Lustres ldiskfs already has MMP support for several years and I would like to know what is the blocker for ext4? Updating the MMP patches for ext4-git should be fairly simple.
