Predix Edge OS Release Notes 2.1.0

These are the enhancements and known issues for Predix Edge OS, version 2.1.0.

New Features

This release contains the following new features:

General
When upgrading Predix Edge OS, the latest versions of system containers (e.g., PETC and Predix Edge Broker) are included in the upgrade file.
OVA
VMware tools are now included in the OVA image.
Raspberry Pi 3 B+
A beta development Predix Edge image for Raspberry Pi 3 B+ is now available.
Note: This image is not for production use. It is to be used only as a reference or demonstration tool.
  • Supported I/Os:
    • 2.4GHz and 5GHz IEEE 802.11.b/g/n/ac wireless LAN, -- CLI only, not configurable via PETC.
    • Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps).
    • Full-size HDMI.
    • Four USB 2.0 ports.
  • Considerations:
    • We are shipping this as a 64-bit OS, portability to 32-bit applications will work, but we do not currently support 32-bit as a platform.
    • Minimum supported SD card size is 4GB, however, a minimum of 8GB is recommended.
    • Note that this system has no real time clock (RTC), meaning the device’s clock will be unreliable until it synchronizes with an NTP server.

Resolved Issues

The following issues were resolved in this release:

  • Automatic disk resizingfailure for VMware virtual machines.

Known Issues

This release has the following known issues:

General
  • Large container deployments may time out if running QEMU without KVM enabled.
  • The only supported virtual disk controller for VMware VMs is IDE; SCSI and SATA are not currently supported.
  • Changes to the system proxy are not propagated into deployed applications. If changing the system proxy settings after deploying applications, the applications need to be stopped and restarted for proxy settings to be propagated into the application.
  • Under high logging conditions, the system consumes more memory due to caching of logs. GE recommends restarting the system.
OVA
  • When using VMware Fusion 10, switching networks in the host system may cause Predix Edge OS VMs to change their IP address (e.g. 192.168.0.5 to 192.168.0.6).
Raspberry Pi 3 B+
  • Once an imaged SDcard has been used to boot a specific Raspberry Pi board, it cannot be used to boot another board. The MAC address and model are written to the SDcard on first boot; from that point on, the SDcard is unique to that board.
    • E.g., you would encounter this issue if you booted a device, then removed and duplicated that SDcard. Devices running both the original, and all the duplicates, would come up with the same address.
