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:
Alasdair Kergon 2014-08-13 18:01:41 EDT
The man page says:
WARNING: The cryptsetup-reencrypt program is not resistant to hardware or kernel failures during reencryption (you can lose you data in this case).
ALWAYS BE SURE YOU HAVE RELIABLE BACKUP BEFORE USING THIS TOOL.
THIS TOOL IS EXPERIMENTAL.
When you run the tool it says:
WARNING: this is experimental code, it can completely break your data.
I'm wondering if that runtime message should be changed to match the man page i.e. to tell you that you MUST take a backup because if the process is interrupted for any reason you will need to restore from it.
Version-Release number of selected component (if applicable):
cryptsetup-reencrypt-1.6.4-1.el6
The utility 'welcome' message has been dropped out. In the man mage there's no longer remark about the utility being experimental, but warning about power/hardware failure implications still apply.
Retested with cryptsetup-reencrypt-1.6.4-2.el6, cryptsetup-reencrypt no longer warns about being experimental, this message has also been removed from its man page.
Moving to VERIFIED.
Since the problem described in this bug report should be
