Expanding storageΒΆ

Follow the steps below to extend a volume on a Plixer ML Engine hardware or virtual appliance.

  1. Add a hard disk to the hardware appliance or VM.

  2. Log in using the credentials plixer:plixer.

  3. Determine the device name of the new disk (usually /dev/sdb):

    lsblk

  4. Extend the volume that requires additional disk space:

    /home/plixer/ml/tools/mladmin.sh --extend <DEVICE> <VOLUME>

    Where DEVICE is the device name of the new disk and VOLUME is one of the following:

    • root - root partition

    • sibyl - models partition (/SibylData)

    • db - database partition (/var/db)

    • zookeepers - Kafka ZooKeeper partition (/var/kafka/zookeepers)

    • brokers - Kafka brokers partition (/var/kafka/brokers)

When done, the selected partition will be extended by the full capacity of the newly added disk.
