David Nalley created CLOUDSTACK-354:
---------------------------------------
Summary: Display of storage statistics is wrong.
Key: CLOUDSTACK-354
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-354
Project: CloudStack
Issue Type: Bug
Components: KVM, Storage Controller, UI
Affects Versions: pre-4.0.0
Environment: 4.0.0 - second release vote, CentOS 6.3 - KVM
Reporter: David Nalley
Priority: Critical
UI Statistics seem inversely calculated
UI is reporting local storage as having 100660162560 of 105689374720 bytes
consumed.
KVM node 1 has the following stats:
/dev/mapper/vg_supv-lv_root
50G 3.3G 44G 8% /
which is really 3436224 45548476 in megabytes
KVM node2 has the following stats:
/dev/mapper/vg_kvm2-lv_root
50G 1.5G 46G 4% /
which is really 1486956 47497744
Combining the two available MB figures comes up with 93046220 available, or
rather 94% free - rather than 95% consumed
Here is what virsh shows for one fo the local storage pools:
virsh # pool-info 11d434ae-d61a-44a3-8bb9-8eba8ac8b015
Name: 11d434ae-d61a-44a3-8bb9-8eba8ac8b015
UUID: 11d434ae-d61a-44a3-8bb9-8eba8ac8b015
State: running
Persistent: yes
Autostart: no
Capacity: 49.22 GB
Allocation: 1.42 GB
Available: 47.80 GB
And here is the response to a listStoragePools - which likewise shows almost
zero usage for the local storage pools
