      Some sites have encountered issues with messages like:

      This issue can cause corruption on storage side. It can be fixed by reverting an upstream patch or adding a udev script (but we will change max_sectors_kb value while mounting time, so it still can be triggered even with this script). The better way is to handle this value in mount.lustre tool. I'll make up a patch for master first.
