Description Alex Stupnikov 2024-04-09 14:51:54 UTC 
Description of problem:

Warnings are logged when os_brick is initialized inside some RHOSP container. For example, the following warning message was logged when copying image from volume
:
2024-04-08 18:06:25.177 20 WARNING os_brick.initiator.connectors.nvmeof [req-UUID ID1 ID2 - default default] Process execution error in _get_host_uuid: Unexpected error while running command.
Command: blkid overlay -s UUID -o value
Exit code: 2
Stdout: ''
Stderr: '': oslo_concurrency.processutils.ProcessExecutionError: Unexpected error while running command.


It is possible to reproduce https://github.com/openstack/os-brick/blob/unmaintained/wallaby/os_brick/initiator/connectors/nvmeof.py#L98-L111 manually:

[root@overcloud-controller0 ~]# podman exec -it glance_api_internal bash
bash-5.1$ findmnt / -n -o SOURCE
overlay
bash-5.1$ blkid overlay -s UUID -o value
bash-5.1$ echo $?
2


There is an upstream bug https://bugs.launchpad.net/os-brick/+bug/2045557


Version-Release number of selected component (if applicable):
RHOSP 17.1


How reproducible:
Please see description


Actual results:
Warning is logged because _get_host_uuid() logic is not ready to process overlayfs

Expected results:
_get_host_uuid() is able to process overlayfs and proceed
Comment 1 Brian Rosmaita 2024-05-09 14:17:07 UTC 
Being tracked upstream, but fix is unlikely to be merged as far back as 17.
Comment 2 Brian Rosmaita 2024-05-09 19:29:05 UTC 
Reopening ... got some feedback from dhill that this is a real annoyance for anyone reading the logs, so might as well backport it to 17.1.
