- Check if zram is enabled:
|
|
|
|
`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:
|
|
|
|
`zramctl`
