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.

Fixed In Version: kexec-tools-2.0.23-1.el9
Doc Type: Enhancement
Doc Text:
.`makedumpfile` now includes improved options to get an estimated `vmcore` size With this implementation, the `makedumpfile` utility now includes the following options which help to print an estimate for the dump size for the currently running kernel: * `--dry-run` performs all operations specified by the other options but does not write the output file. * `--show-stats` prints the report messages. This is an alternative to enabling bit 4 in the level provided to `--message-level` option. The following example shows the `--dry-run` and `--show-stats` usage: ---- $ makedumpfile --dry-run --show-stats -l --message-level 7 -d 31 /proc/kcore dump.dummy ---- Note that the dump file size may vary depending on the system state at the time of panic and the estimate provided by the options may differ from the actual state.
