Signals Data Factory - How to get the available disk space

The Problem

How can an administrator check the available disk space on their cluster

The Solution

There are kubectl commands that can be run to output the disk space—

To get the overall disk space:

Command

kubectl -n rook-ceph exec -it $(kubectl -n rook-ceph get pods | grep tools | awk '{print $1}') -- ceph -s

Example Output

cluster:
    id:     6d3c4e36-bb11-4e02-a05f-04e3fd3cb04a
    health: HEALTH_OK
  services:
    mon: 3 daemons, quorum a,b,c (age 2w)
    mgr: a(active, since 4M)
    osd: 3 osds: 3 up (since 3M), 3 in (since 4M)
    rgw: 3 daemons active (signals.store.a, signals.store.b, signals.store.c)
  task status:
  data:
    pools:   8 pools, 256 pgs
    objects: 300.59k objects, 674 GiB
    usage:   1.3 TiB used, 1.2 TiB / 2.5 TiB avail
    pgs:     256 active+clean
  io:
    client:   85 B/s rd, 8.2 KiB/s wr, 0 op/s rd, 0 op/s wr

To get the space on each available machine

Command

kubectl -n rook-ceph exec -it $(kubectl -n rook-ceph get pods | grep tools | awk '{print $1}') -- ceph osd status
