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.

Expected results:


Additional info:

lvm2-2.02.95-6.el7.x86_64

where can I get the thin_check and thin_dump?

lvm2 currently does not have dependency on

device-mapper-persistent-data

which must be installed separately

Since not all users are going to use thin - dependency here is tricky - we need to came with some better solution - i.e. check before  lvcreate if tools are avaialble)

We'll have a dependency when this becomes supported, but not while it's tech preview (as we shouldn't install a pure tech preview package for everyone by default).

Thanks all for the clarification.

I am putting thin_check_executable = "" to the global{} in lvm.conf to skip this check.

Is it expected to be TP still in RHEL 7 GA?

> Is it expected to be TP still in RHEL 7 GA?

No, should be fully supported.

In that case, I don't see any reason not to add the dep in the RHEL 7 packages.

lvm2 build that requires device-mapper-persistent-data has already been automatically imported from Fedora to RHEL7 as lvm2-2.02.97-1.el7.
