Hi!
I can confirm this.
--grow on LVM partition is broken for raid+lvm kickstart installs.
bootloader --location=mbr --driveorder=sda,sdb --append="net.ifnames=0
crashkernel=auto rhgb quiet"
zerombr
clearpart --all --drives=sda,sdb --initlabel
part raid.1 --asprimary --size=200 --ondisk=sda
part raid.2 --size=1 --grow --ondisk=sda
part raid.3 --asprimary --size=200 --ondisk=sdb
part raid.4 --size=1 --grow --ondisk=sdb
raid /boot --fstype=ext4 --level=RAID1 --device=md0 raid.1 raid.3
raid pv.1 --level=RAID1 --device=md1 raid.2 raid.4
volgroup vg0 --pesize=65536 pv.1
logvol swap --name=swap --vgname=vg0 --size=4096
logvol /tmp --fstype=ext4 --name=tmp --vgname=vg0 --size=4096
--fsoptions="noexec,nosuid,nodev,noatime"
logvol / --fstype=ext4 --name=root --vgname=vg0 --size=10240 --grow
--fsoptions="defaults,noatime"
Such partitioning scheme is now working. Anaconda is complaining about
"ValueError: not enough free space in volume group"
Buf if I remove --grow from last logvol - everything is ok.
I don't understand what I'm doing wrong, such kickstart works
flawlessly for C6 installs.
