Subject: ceph-docker-prs: Moving image{s} directories to shm
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=bf55ee3e19d1fee16e2a2e2c33b40e846b3a35de;p=ceph-build.git

ceph-docker-prs: Moving image{s} directories to shm

On the CI, the root disk is pretty slow (20-30MB/sec).
This patch is about moving the big directories into /dev/shm to speedup the builds.
We can count up to 7GB of storage that doesn't it the cold storage but RAM (~9000MB/sec).
