Pages written to these disks are compressed and stored -in memory itself. These disks allow very fast I/O and compression provides -good amounts of memory savings. Some of the usecases include /tmp storage, -use as swap disks, various caches under /var and maybe many more :) - -Statistics for individual zram devices are exported through sysfs nodes at -/sys/block/zram<id>/ - -* Usage - -Following shows a typical sequence of steps for using zram. - -1) Load Module: - modprobe zram num_devices=4 - This creates 4 devices: /dev/zram{0,1,2,3} - (num_devices parameter is optional. Default: 1) - -2) Set Disksize - Set disk size by writing the value to sysfs node 'disksize'. - The value can be either in bytes or you can use mem suffixes. - Examples: - # Initialize /dev/zram0 with 50MB disksize - echo $((50*1024*1024)) > /sys/block/zram0/disksize - - # Using mem suffixes - echo 256K > /sys/block/zram0/disksize - echo 512M > /sys/block/zram0/disksize - echo 1G > /sys/block/zram0/disksize - -3) Activate: - mkswap /dev/zram0 - swapon /dev/zram0 - - mkfs.ext4 /dev/zram1 - mount /dev/zram1 /tmp - -4) Stats: - Per-device statistics are exported as various nodes under - /sys/block/zram<id>/ - disksize - num_reads - num_writes - invalid_io - notify_free - discard - zero_pages - orig_data_size - compr_data_size - mem_used_total - -5) Deactivate: - swapoff /dev/zram0 - umount /dev/zram1 - -6) Reset: - Write any positive value to 'reset' sysfs node - echo 1 > /sys/block/zram0/reset - echo 1 > /sys/block/zram1/reset - - This frees all the memory allocated for the given device and - resets the disksize to zero. You must set the disksize again - before reusing the device. - -Please report any problems at: - - Mailing list: linux-mm-cc at laptop dot org - - Issue tracker: http://code.google.com/p/compcache/issues/list - -Nitin Gupta -ngupta@vflare.org |
