Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Bug 2192618

Description jcastran 2023-05-02 14:11:26 UTC
Description of problem:
When xfs partitions are bind mounted, leapp treats each one as an individual xfs partition. If we have ftype=0, then leapp assumes each one needs an overlay which increases the amount of space needed in /var/lib/leapp.

This customer had 12 xfs partitions, but only 2 were valid. The other 10 were bind mounts. Leapp reported that we needed 36GB (With a 3G OVL size) in /var/lib/leapp but upon reboot, only used 6-7 GB (as the bind mounts were not in the fstab so do not mount upon boot).


Version-Release number of selected component (if applicable):
leapp-0.15.0-2.el7_9.noarch 
leapp-deps-0.15.0-2.el7_9.noarch 
leapp-upgrade-el7toel8-0.17.0-10.el7_9.noarch     
leapp-upgrade-el7toel8-deps-0.17.0-10.el7_9.noarch
python2-leapp-0.15.0-2.el7_9.noarch

How reproducible:
Everytime

Steps to Reproduce:
1. Have a system with ftype=0 on an xfs partition
2. bind mount any xfs partitions any number of times
3. leapp upgrade

Actual results:
====> * target_userspace_creator
        Initializes a directory to be populated as a minimal environment to run binaries from the target system.
2023-04-27 10:24:27.525 ERROR    PID: 12215 leapp.workflow.TargetTransactionFactsCollection.target_userspace_creator: Not enough space available for creating required disk images in /var/lib/leapp/scratch. Needed: 36864 MiB

Expected results:
We could base calculations off only whats in the fstab to avoid bind mounts. 
Or a warning that # bind mounts are present and affecting this size estimate.

Lowering the priority as it's expected to be a corner case.
