Varnish working directory space requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Ensure that the varnish working directory as specified by the ``-n``
argument to ``varnishd`` has sufficient space to hold *buddy* and
*fellow* metadata (bitmaps). It defaults to ``/var/run/varnish``, but
is often changed by packagers to ``/var/lib/varnish``.
As a rule of thumb with rounded up numbers, the amount of space needed
in the working directory is roughly:
- 5 MB for each GB of memory cache
- 65 MB for each TB of disk cache
*Note* that this is **megabytes** for gigabytes of memory and terabytes of
disk.
