Description Francois Palin 2023-10-26 15:48:33 UTC

Description of problem:

Running "openstack overcloud upgrade run --yes --tags system_upgrade --stack tpa-vim-c" fails for computesl-1 due to NFS mount for a VM on the host.

[tripleo-admin@abc-def-c-computesl-1 log]$ sudo grep -A9 inhibitor /var/log/leapp/leapp-report.txt
Risk Factor: high (inhibitor)
Title: Use of NFS detected. Upgrade can't proceed
Summary: NFS is currently not supported by the inplace upgrade.
We have found NFS usage at the following locations:
- NFS shares currently mounted:

Remediation: [hint] Disable NFS temporarily for the upgrade if possible.
