Omkar Dhayagude commented on HDDS-11772:
----------------------------------------
[~zitadombi] , I used below command to load data of total size 100 MB (1000
keys in total each of 100 KB):
{code:java}
# ozone freon ozone-client-key-generator --duration=15m --size=102400{code}
Also, after replication, this is the disk usage:
{code:java}
# ozone fs -du -v ofs://ozone1731569798/vol1/bucket1
SIZE DISK_SPACE_CONSUMED_WITH_ALL_REPLICAS
102400000 307200000{code}
After doing info on volume, here is result:
{code:java}
# ozone sh volume info vol1
{
"metadata" : { },
"name" : "vol1",
"admin" : "om",
"owner" : "om",
"quotaInBytes" : -1,
"quotaInNamespace" : -1,
"usedNamespace" : 1,
"creationTime" : "2024-11-14T11:14:39.060Z",
"modificationTime" : "2024-11-14T11:14:39.060Z",
"acls" : [ {
"type" : "USER",
"name" : "om",
"aclScope" : "ACCESS",
"aclList" : [ "ALL" ]
}, {
"type" : "GROUP",
"name" : "om",
"aclScope" : "ACCESS",
"aclList" : [ "ALL" ]
} ],
"refCount" : 0

> Ozone Used Capacity shown in Recon is not matching with the input data size

>
> Key: HDDS-11772
> URL: https://issues.apache.org/jira/browse/HDDS-11772
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Recon
> Reporter: Omkar Dhayagude
> Priority: Major
>
> *Steps to reproduce issue:*
> 1. Create a cluster
> 2. Go Ozone Recon & note down the original Cluster Capacity and number of
> keys, buckets & volumes.
> Hover over Cluster Capacity bar to see more details & note Ozone Used space.
> 3. The values are:
> * Cluster Capacity = ~984.4 GB
> * Ozone used = 1.7 GB
> * Volumes = 1 | Buckets = 1 | Keys = 0
> 4. From CLI start a freon workload for 15 mins to load data of size 100 MB
> 5. After 15 mins i.e. after finishing the WL and considering replication
> factor (RF = 3), disk space consumed for Ozone is 307200000 bytes = 300 MB.
> 6. Now go to Recon web UI & observe the previously noted parameters again.
> 7. Also check the volume/bucket/keys size from Recon > Disk Usage
>
> *Observed results:*
> 1. The values are:
> * Cluster Capacity = ~1 TB
> * Ozone used = 56.5 GB
> * Volumes = 2 | Buckets = 2 | Keys = 1000
> * Disk Usage: vol1/bucket1 = 97.7 MB
> Here, the ozone used space is increased from 1.7 GB to 56.5 GB, where we
> loaded only ~ 300 MB.
> 2. The before & after values have irrelevant difference and are inconsistent
> mathematically.
>
> *Expected result:*
> Ozone used capacity in Recon should match according to the input data loaded.
