Using persistent volume in BuildConfig on OpenShift Container Platform

Issue

• We're facing an issue where, in a s2i build, the git clone is filling the /var/lib/origin filesystem on the node, leading to a nodefs event and triggering a pod eviction. /var/lib/origin is 5GB, and the git repository, including the .git directory, is taking around 90% of the storage once pulled. We are now wondering on whether it is possible to specify another build directory, for example use a persistent volume and doing a claim in the BuildConfig, where the git repository would be cloned ?
