Disk 415104829 (SSD) was added yesterday. I also added one ssd to 2 nodes tonight. The new ssd’s are very busy right now.

Hello @kfr- 

Garbage egroups is data that is no longer in use by the system but that is still taking up space. Due to the way the Nutanix file system works, it is expected to have a small amount of garbage on the cluster. However, the system is periodically cleaning up garbage egroups in the background via Curator scans.

Things that need to be check:

  1. Make sure you are on the latest NCC version (4.0.1), as the thresholds for this check were adjusted in NCC 3.9.0 and above for improved accuracy.
  2. Make sure you are on the 5.10+ AOS version.
  3. Make sure the curator service is running. You can check this using two commands:
    • nutanix@cvm$ cluster status
    • nutanix@cvm$watch -d genesis status
  4. Garbage details are found using nutanix@cvm$curator_cli display_garbage_report this command.

Please let me know if you have further questions.
