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:
Anaconda does not reserve free space on a Volume group when "volgroup --reserved-percent=##" is used.
Version-Release number of selected component (if applicable):
RHEL 8
How reproducible:
Everytime
Steps to Reproduce:
1. Create a kickstart with manual partitioning and specify a reserved-percent
clearpart --all --initlabel
zerombr
part pv.01 --size=1 --grow --ondisk=sda
volgroup vg0 pv.01 --reserved-percent=30
part /boot --size=500 --ondisk=sda --fstype=xfs
logvol / --name=root --vgname=vg0 --size=5000 --grow
2. kickstart the system
Actual results:
The volume group is completely consumed
Expected results:
the specified percentage should have been reserved
Additional info:
Kickstart installs with volume group snapshot capability is not possible With RHEL 8 at this time since it does not properly handle the "--reserved-percent". Please confirm/triage this issue.
Also note that "--reserved-space" is not possible in place as it actually produces an error on install... Not sure if that's an open ticket, but "--reserved-space" is not working as a drop in replacement.
If it helps, the logvol "--percent" does seem to work. This combo finally got me dynamic disk size usage+LVM+encryction+snapshot(via free VG sapce) in my kickstart:
# Partition clearing information
ignoredisk --only-use=sda
zerombr
clearpart --all --initlabel
# Disk partitioning information
part /boot/efi --fstype="efi" --ondisk=sda --size=600 --fsoptions="umask=0077,shortname=winnt"
part pv.314 --fstype="lvmpv" --ondisk=sda --size=1000 --grow --encrypted --luks-version=luks1 --passphrase=somepassphrase
part /boot --fstype="ext4" --ondisk=sda --size=1024
volgroup VGslash --pesize=4096 pv.314 --reserved-percent=5
logvol / --fstype="xfs" --percent=95 --name=lvslash --vgname=VGslash --label="slash"
logvol swap --fstype="swap" --size=12962 --name=lvswap --vgname=VGslash --label="swap"
