I am having a bosh lite VM for testing purpose, and it's running out of space after several days.
And comparing to a new build, I can see the disk is used by "warden_cpi"
the clean VM: root(a)agent-id-bosh-0:/var/vcap/store/warden_cpi# du -sh ./* 1.7G ./disks 4.7G ./ephemeral_bind_mounts_dir 120K ./persistent_bind_mounts_dir 1.3G ./stemcells
VM running for several days: root(a)agent-id-bosh-0:/var/vcap/store/warden_cpi# du -sh ./* 21G ./disks 30G ./ephemeral_bind_mounts_dir 3.8G ./persistent_bind_mounts_dir 1.3G ./stemcells
It looks like the disk space is used by some cache objects are these cache objects are not delelted. Is there any script to clean them up?
