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). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
I was just playing around here w/ what I saw on the man page, but with a real (non bootable) snapshot

Comment 2 Bryn M. Reeves 2018-01-08 17:26:11 UTC 
OK. I think I see what's up here - for some reason the pacakged profiles are not being included in /boot for the lvm2-python-boom subpackage (the original Copr builds do include these files):

# rpm -ql lvm2-python-boom | grep boom\/profiles
/boot/boom/profiles
/usr/share/doc/lvm2-python-boom-0.8.1/tests/boom/profiles
/usr/share/doc/lvm2-python-boom-0.8.1/tests/boom/profiles/01f4a140de8c7cb9083be599e61d26bdff2c2c97-debian8.profile
/usr/share/doc/lvm2-python-boom-0.8.1/tests/boom/profiles/21e37c8002f33c177524192b15d91dc9612343a3-ubuntu16.04.profile
/usr/share/doc/lvm2-python-boom-0.8.1/tests/boom/profiles/28851f93a99cad97a0082fcd0270da994b2bff7a-newos1.profile
/usr/share/doc/lvm2-python-boom-0.8.1/tests/boom/profiles/3ee2c8b6e7b5043d305bc2850ba01f4838739a1b-nooptions1.profile
/usr/share/doc/lvm2-python-boom-0.8.1/tests/boom/profiles/3fc389bba581e5b20c6a46c7fc31b04be465e973-rhel7.2.profile
...

So although they are there in /usr/share/doc they are not usable (since boom stores all its configuration in /boot so that it is available to all OS instances).

If you still have the machine available, could you try a quick confirmation by just copying those files from /usr/share/doc/... to /boot/boom/profiles?

I expect the output of "boom profile list" is empty too.

So it should be just a simple packaging change to fix this problem but I'll also make sure we output a more helpful error message - I was expecting that to get caught already so there's obviously some bug there.

I believe this is also the problem in bug 1528018.
Comment 3 Bryn M. Reeves 2018-01-17 15:50:50 UTC 
The ugly backtrace is fixed in upstream release 0.8.2, which should be picked up in a build shortly and the remaining problem (missing profiles in /boot) should just be a simple packaging fix.
Comment 5 Corey Marthaler 2018-01-30 17:15:49 UTC 
Marking verified with the latest rpms. The tracebacks now appear fixed.
