Hello everyone,
For virtual machines I used two drives ada5 & ada6 in a pool called VMachines. Using TrueNAS-12.0-U8 standard tools I have created a Virtual machine (Ubuntu 21.1) and assigned Zvol "model_ca-59sqxf" on the VMachines pool. It's visible from "Storage" -> pool and from "Virtual Machines" -> edit -> disk menu. Then I attempted to create a manual snapshot using these steps: Storage -> Snapshots -> Add -> Dataset "VMachines/amodel_ca-59sqxf", I tried both, the default and Recursive option. After creating a couple empty files I rolled back the snapshot and all the files are still there so the snapshot didn't return the VM to the original status.
Could you please help me figure out what could cause this behavior? Do I have to stop the VM before and during snapshot / rollback?
