Setup:
On one of the nodes, the `/etc/lvm/archive` contains 894035 files amounting to 3.5 GiB of space.
They appear to contain information about the LVM inside VMs:
lsblk for 3PAR Disk
Here are some statistics about the files inside `/etc/lvm/archive`.
First Column: Number of files inside `/etc/lvm/archive`
- 3 Node VE (8.3.5) Cluster with Ceph and additional 3PAR Storage (Fibre Channel exposed to the Host)

- I reduced the retain_days inside lvm.conf to 10 days but it does not seem to do any clean up
- Is it safe to delete data inside `/etc/lvm/archive/*` manually?
