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.

The RHEL-6 deployment guide should explain the reserved space capability for kickstart installs.  Customers wanting to plan for upgrades to the next major release should be using LVM and reserving space in their volume group so that upgrades will work in the future.  The amount of space reserved varies, but should allow for a snapshot to be taken of the root filesystem.

Thank you very much for taking the time to file this bug, David. The Deployment Guide, however, does not describe LVM, nor does it document kickstart installation. The Deployment Guide does mention LVM snapshots, but only as a part of the description of the fs-snapshot plug-in for Yum. And from the errata description, it looks like it would make more sense to document this in the Installation Guide. Please, correct me if I am wrong.

Comment 4 David Cantrell 2014-06-23 12:14:33 UTC

If the Installation Guide is appropriate, that's fine with me.  I do not completely understand the difference between the Installation Guide and Deployment Guide.  I'll reassign it to Installation Guide.
