[pve-devel] [PATCH v2 storage 0/2] show storage-utilization per pool

[Alwin Antreich]

My goal behind changing the storage utilization for ceph is, that it shows
currently the global available/used storage space and calculates the usage
percentage based on it.
This is suboptimal in some cases, eg. multiple pools with different
size/min_size on the same root, recovery or the ceph pool is not residing on
all OSDs in the cluster.

To get a usage per pool basis, I use the librados2-perl bindings
(hence the update to v1.0-5), as the ceph command line tool doesn't work w/o
a config file and rados doesn't provide the necessary information on its
command line.

The storage status calculates a percent_used for ceph clusters prior Kraken,
in releases >= Kraken the percent_used is provided by ceph. The GUI, while not
using the percent_used, will show correct values, with the exception when a
recovery is running. The CLI uses the percent_used.
