RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit).

Description Micah Abbott 2016-04-29 20:02:17 UTC
Description of problem:
When running 'docker-latest-storage-setup' on an upgraded RHELAH, the service fails with the error:

/usr/bin/docker-latest-storage-setup: line 372: local: `docker-latest_devmapper_meta_dir=/var/lib/docker-latest/devicemapper/metadata/': not a valid identifier


Version-Release number of selected component (if applicable):
# rpm -q docker-latest
docker-latest-1.10.3-19.el7.x86_64


How reproducible:
Pretty consistently

Steps to Reproduce:
1.  Boot into RHELAH 7.2.3-1
2.  Upgrade to 7.2.4 and reboot
3.  systemctl stop docker
4.  systemctl start docker-latest-storage-setup


Actual results:
Apr 29 19:56:10 rhel-atomic-7.2-test systemd[1]: Starting Docker Storage Setup...
Apr 29 19:56:10 rhel-atomic-7.2-test docker-latest-storage-setup[11457]: /usr/bin/docker-latest-storage-setup: line 372: local: `docker-latest_devmapper_meta_dir=/var/lib/docker-latest/devicemapper/metadata/': not a valid identifier
Apr 29 19:56:10 rhel-atomic-7.2-test systemd[1]: docker-latest-storage-setup.service: main process exited, code=exited, status=1/FAILURE
Apr 29 19:56:10 rhel-atomic-7.2-test systemd[1]: Failed to start Docker Storage Setup.
Apr 29 19:56:10 rhel-atomic-7.2-test systemd[1]: Unit docker-latest-storage-setup.service entered failed state.
Apr 29 19:56:10 rhel-atomic-7.2-test systemd[1]: docker-latest-storage-setup.service failed.



Expected results:
'docker-latest-pool' LV created


Additional info:
I found that if I change the name of the variable 'docker-latest_devmapper_meta_dir' in the script to use all underscores 'docker_latest_devmapper_meta_dir', the script will run sucessfully.

Comment 2 Vivek Goyal 2016-04-29 20:54:08 UTC
Lokesh, we had discussed this one. We don't have to replace the variable name with docker-latest. Did you get a chance to make it working.

Comment 3 Lokesh Mandvekar 2016-05-02 18:19:23 UTC
upcoming fix...
