[pve-devel] [PATCH manager] fix #5293: ceph status: fix division-by-zero when calculating usage

[Christoph Heiss <c.heiss@proxmox.com>]

Fixes #5293 [0]. This happens when no OSDs are created yet and thus the
total space is 0, which leads to a division-by-zero.

Add a simple check if the total space is greater than 0.
