1.1.4. Known Issues/Workarounds

TrilioVault 3.5 GA release contains the following known issues which will be addressed in future releases

IssueID Summary Workaround (if any)
RHV-290 Global Scheduler when enabled after re-initialize and reconfiguration of TVM, the local workload schedulers are not auto-enabled
  • Keep Global Scheduler enabled.
  • Perform Re-initialize of TVM.
  • Perform Import all workloads.
  • Observe Backup tab –> Workload –> Policy tab –> “Next Snapshot Run at”
  • Next run shows the correct run time and backup job is getting triggered at the exact given “Next run” time.
RHV-288 Scheduler: Setting up a future date schedule is failing Select time of future scheduler date as more than current time.
RHV-287 Ansible playbook (tags daemon) fails if backup target (NFS) is already mounted on RHV host
  • Manually umount the nfs backup target from RHV host and then re-run the playbook.
  • Run the Uninstall Script on TVM as given
# cd /opt/stack/imageio-ansible
# ansible-playbook site.yml -i
  inventories/production/daemon --tags
  clean-daemon
# ansible-playbook site.yml -i
  inventories/production/proxy --tags
  clean-proxy

This will remove the NFS target mounts from all hosts
