Hello @khinhvuphiduong, thank you for taking the time to report the bug. Im working on trying to reproduce it, but working with volumes requieres also some extra configuration, can you please share all the job file? Also if you have any configuration regarding the use of volumes on the agent specs, we could use that one too.
