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:
When using the "part" directive in a kickstart file, --fsoptions isn't honored when used for a Btrfs filesystem.
How reproducible:
Specify valid filesystem options for Btrfs in the kickstart file.
Steps to Reproduce:
Create a valid kickstart file. For the section specifying the filesystem layout use:
part /boot --fstype="xfs" --size=200 --fsoptions="noatime,discard"
part btrfs.01 --grow --fsoptions="noatime,compress=lzo,autodefrag,discard"
btrfs none --label=rhel --data=single btrfs.01
btrfs / --subvol --name=root rhel
Actual results:
After installation, checkout the resulting fstab file. The fsoptions will have correctly propagated to the xfs partition but not the Btrfs one.
Expected results:
Anaconda should honor these additional options for Btrfs. **BONUS** Provide a way to specify then through the GUI during a non-kickstart installation.
Additional info:
As a workaround, I've been able to do the following with my ks file:
%post
# Fixup btrfs (shouldn't have to do this)
sed -i 's/subvol=/noatime,compress=lzo,autodefrag,discard,subvol=/g' /etc/fstab
mount -o remount /
btrfs filesystem defrag -r -clzo /
%end
There seems to be a similar bug for Fedora 20. I'm not sure if that classifies this as redundant. I wanted to make sure this was on the RHEL team's radar.
