Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 Flags
xfsdump archive produced using xfsdump-3.1.4-1.el7 with a bind mount none

Description Donald Douwsma 2023-08-25 07:05:02 UTC
Created attachment 1985232 [details]
xfsdump archive produced using xfsdump-3.1.4-1.el7 with a bind mount

Description of problem:

xfsdump/xfsrestore: suggest recovery for false roots may be possible using -x

Description of problem:

Some versions of xfsdump may produce archives that cannot be restored correctly
problems with bind mounts identified in Bug 1698057, a fix to restore these
archives was made in Bug 2034327.

This fix uses a new option `-x` to allow archives to be restored, unfortunately
for the case where an archive causes xfsrestore to fail with an assert there's
no direction given to the user that recovery may be possible.

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

 xfsdump-3.1.10-1.el9.x86_64

Steps to Reproduce:
Using the xfsdump attached to the bz

 mkdir /tmp/test
 xfsrestore -f bind_mount-xfsdump-3.1.4-1.el7.x86_64.dump /tmp/test

Actual results:
 xfsrestore: using file dump (drive_simple) strategy
 xfsrestore: version 3.1.10 (dump format 3.0) - type ^C for status and control
