Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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 Corey Marthaler 2011-02-08 21:04:27 UTC

Description of problem:
After making lvm aware of swap labels (bug 488354), it would be nice if the reverse was also implemented. If you have a valid LVM volume with data on it, and you deactivate it, and mkswap it, you lose that data. It would be nice if mkswap could detect valid LVM labels and verify that the operation to be preformed is what's really desired.


Version-Release number of selected component (if applicable):

Comment 2 Karel Zak 2011-03-18 09:09:02 UTC

It's unusual request, all our mkfs-like utils making a new FS without any care about the current content on the device. A small exception is mkfs.xfs where is necessary -f (force) to overwrite an old FS.

The requested change will also break backward compatibility. Sorry, closing.
