zramctl

linux

Setup and control zram devices. Use `mkfs` or `mkswap` to format zram devices to partitions.

Options (4)

-i, --ignore-caseboolean

Check if zram is enabled

Example: lsmod | grep {{[-i|--ignore-case]}} zram

-f, --findboolean

Find and initialize the next free zram device to a 2 GB virtual drive using LZ4 compression

Example: sudo zramctl {{[-f|--find]}} {{[-s|--size]}} {{2GB}} {{[-a|--algorithm]}} {{lz4}}

-s, --sizeboolean

Find and initialize the next free zram device to a 2 GB virtual drive using LZ4 compression

Example: sudo zramctl {{[-f|--find]}} {{[-s|--size]}} {{2GB}} {{[-a|--algorithm]}} {{lz4}}

-a, --algorithmboolean

Find and initialize the next free zram device to a 2 GB virtual drive using LZ4 compression

Example: sudo zramctl {{[-f|--find]}} {{[-s|--size]}} {{2GB}} {{[-a|--algorithm]}} {{lz4}}

Check if zram is enabled

lsmod | grep [-i|--ignore-case] 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 [-f|--find] [-s|--size] 2GB [-a|--algorithm] lz4

List currently initialized devices

sudo zramctl
