    lsmod | grep -i zram
     
  • Enable zram with a dynamic number of devices (use zramctl to configure devices further):
     
    sudo modprobe zram
     
  • Enable zram with exactly 2 devices:
     
    sudo modprobe zram num_devices={{2}}
     
  • Find and initialize the next free zram device to a 2 GB virtual drive using LZ4 compression:
     
    sudo zramctl --find --size {{2GB}} --algorithm {{lz4}}
     
  • List currently initialized devices:
