ansible-swapfile

This role configures a swapfile (/swapfile) with the (default) size of 512MB.

Dependencies

None.

Variables

  • swapfile_use_dd [default: False]: if set to False, fallocate is used to create the swapfile, otherwise, dd is used. You may need to set this to True if your filesystem does not support fallocate -- see Issue #3.

  • swapfile_size [default: 512MB]: the size of the swapfile to create in the format that fallocate expects:

    The length and offset arguments may be followed by binary (2^N) suffixes KiB, MiB, GiB, TiB, PiB and EiB (the "iB" is optional, e.g. "K" has the same meaning as "KiB") or decimal (10^N) suffixes KB, MB, GB, PB and EB.

    If swapfile_use_dd is set to True, swapfile_size must be set to the amount of megabytes to write, e.g. 512.

  • swapfile_location [default: /swapfile]: the location of where the swapfile will be created

Optional

The following variables are set to False by default and will not have any effect on your hosts. Setting them to any value other than False will update your hosts' sysctl.conf file.

  • swapfile_swappiness [default: False]: the swappiness percentage (vm.swappiness) -- the lower it is, the less your system swaps memory pages

  • swapfile_vfs_cache_pressure [default: False]: "this percentage value controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects."

Usage

- hosts: all
  roles:
    - kamaln7.swapfile

or:

- hosts: all
  roles:
    - { role: kamaln7.swapfile, swapfile_size: 1GB, swapfile_swappiness: 10, swapfile_location: /mnt/swapfile }

You can also set the variables described above in group_vars or host_vars (see defaults/main.yml).
