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:

    "A linear volume aggregates multiple physical volumes
     into one logical volume."

"multiple" should be stated as "1 or more", no?

Logical_Volume_Manager_Administration(EN)-6 (2011-11-14-15:20)

That's true, you can have a logical volume with only one PV (and there are often good reasons for that), which makes this sentence technically wrong. But the focus of that whole subsection is (at an absolute beginner level) the concept that you can aggregate different pieces of hardware so that they look to the system as if they were one piece of hardware. A "logical" piece of hardware.

So it would be technically better to fix it, but there's a part of me wondering if that could possibly be confusing right at this point in the overview. I'm thinking I should make the change, but before doing that I will run this by a couple of other folks just to be sure that this doesn't confuse things -- or to see if I can make it accurate without confusing things, perhaps by adding other information about why you might want to have a logical volume containing only one PV.

Thanks for pointing this out.

Moving this to 6.4 because of when this arrived (after development freeze for 6.3). It doesn't seem show-stopping enough to exception.

The 6.4 draft of the LVM document now replaces the noted sentence with the following:

"A linear volume aggregates space from one or more physical volumes into one logical volume."
