Title:
  mysqldump-lvm does not log enough on failure

Status in Holland Backup Framework:
  Triaged
Status in holland-backup 2.0 series:
  New

Bug description:
  When a snapshot is invalidated and mysqld crashes as a result, there
  is no information logged about what went wrong.  Only by correlating
  dmesg or other logging to the time when holland failed is it all clear
  that the reason a backup failed was due to snapshot invalidation (e.g.
  ran out of space allocated to the snapshot)

  holland lvm plugins really should always check the snapshot volume at
  the end and if lv_attr has an 'S' flag, we should verbosely log that
  the snapshot appears to have been invalidated.

  Further the mysqldump-lvm plugin should try to grab the last few lines
  of the mysqld error log to indicate what failed, if holland's spawned
  mysqld process is not running when we attempt to terminate it.
