   In 1.7.0 and later, new tablets are assigned a disk group consisting of

  -with enough data directories for a full disk group, all data directories are
  -used. When a data directory is full, Kudu will stop writing new data to it and
  -each tablet that uses that data directory will write new data to other data

  -full, and will resume writing to those data directories if space has become

   If Kudu does crash because its data directories are full, freeing space on the
   full directories will allow the affected daemon to restart and resume writing.
  
positive.code: 
  While in this state, the affected node will avoid using the failed disk,
  leading to lower storage volume and reduced read parallelism. The administrator
  should schedule a brief window to <<change_dir_config,update the node's
  directory configuration>> to exclude the failed disk.
  
  When the disk is repaired, remounted, and ready to be reused by Kudu, take the
  following steps:
  
  . Make sure that the Kudu portion of the disk is completely empty.
  . Stop the tablet server.
  . Run the `update_dirs` tool. For example, to add `/data/3`, run the following:
  +
  [source,bash]

  UNIX user, typically `kudu`.
  
  . Establish a
    <<minimizing_cluster_disruption_during_temporary_single_ts_downtime,maintenance
    window>> and shut down the tablet server.
  
  . Run the tool with the desired directory configuration flags. For example, if a
    cluster was set up with `--fs_wal_dir=/wals`, `--fs_metadata_dir=/meta`, and
