Merge pull request #3958 from simplesurance/swappiness 
fix: disable swap for executor_linux allocations
 2018-03-13 10:10:22 -07:00
Fabian Holler e6af051c93 fix: disable swap for executor_linux allocations 
A comment in the nomad source code states that swapping for
executor_linux allocations is disabled but it wasn't.

Nomad wrote -1 to the memsw.limit_in_bytes cgroup file to disable
swapping.
This has the following problems:

1.) Writing -1 to the file does not disable swapping. It sets
    the limit for memory and swap to unlimited.
2.) On common Linux distributions like Ubuntu 16.04 LTS the
    memsw.limit_in_bytes cgroup file does not exist by default.
    The memsw.limit_in_bytes file only exist if the Linux kernel is
    build with CONFIG_MEMCG_SWAP=yes and either
    CONFIG_MEMCG_SWAP_ENABLED=yes or when the kernel parameter
    swapaccount=1 is passed during boot.
    Most Linux distributions disable swap accounting by default because
    of higher memory usage.
    Nomad silently ignores if writing to the memsw.limit_in_bytes file
    fails. The allocation succeeds, no message is logged to notify the
    user.

To ensure that disabling swap works on common Linux kernels, disable
swapping by writing 0 to the memory.swappiness file.
Using the memory.swappiness file only requires that the kernel is
compiled with CONFIG_MEMCG=yes. This is the default in common Linux
kernels.
