The drives holding our DDB are currently fluctuating between 85 and 95% full. We’re in the process of procuring larger drives to replace the ones currently in our mediaagent, but in the meantime…what happens if the drive holding our DDB hits 100% capacity?

Hi
Thanks for reaching out, once the minimum free space is reached (default and lowest is 5GB) it will place the partition offline.
Min Free space can be found in https://documentation.commvault.com/2023e/expert/93891_online_help.html
