I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks. Partitioning is lvm over raid.
If i am using "logvol --grow i get "ValueError: not enough free space in volume group" Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available. (10 extents or 320Mb per created logical volume)
Following snippet is failing with "DEBUG blivet: failed to set size: 640MB short"
part raid.01 --size 512 --asprimary --ondrive=sda part raid.02 --size 1 --asprimary --ondrive=sda --grow part raid.11 --size 512 --asprimary --ondrive=sdb part raid.12 --size 1 --asprimary --ondrive=sdb --grow raid /boot --fstype="xfs" --device="md0" --level=RAID1 raid.01 raid.11 raid pv.01 --fstype="lvmpv" --device="md1" --level=RAID1 raid.02 raid.12 volgroup vg0 pv.01 logvol / --fstype="xfs" --grow --size=4096 --name=lvRoot --vgname=vg0 logvol swap --fstype="swap" --size=2048 --name=lvSwap --vgname=vg0
If i only add --maxsize=13164 everything is working. (but after install i have 640MB in 20 Free PE in vg0, for details see "after --maxsize install")
logvol / --fstype="xfs" --grow --size=4096 --name=lvRoot --vgname=vg0 ------changed to -----> logvol / --fstype="xfs" --grow --size=4096 --name=lvRoot --vgname=vg0 --maxsize=13164
Some interesting DEBUG lines :
should it be 11744 or there is 320MB overhead ?
Adding vg0-lvSwap/2048MB to vg0 vg vg0 has 9056MB free
320MB missing again, total of 640MB
vg vg0: 9056MB free ; lvs: ['lvRoot', 'lvSwap']
nice, i have 9056MB free in vg0 (640MB short but still ... )
1 requests and 303 (9696MB) left in chunk adding 303 (9696MB) to 27 (vg0-lvRoot)
wtf, who is counting what !!
failed to set size: 640MB short
Could anyone shed some light ?
P.S.
"after --maxsize install" ========================= If i limit root logvol with --maxsize=13164, after installation i get 640MB of free space (20 Free PE).
Missing 640Mb is free according to lvm : [root@c7-pxe-install ~]# pvdisplay --- Physical volume --- PV Name /dev/md1 VG Name vg0 PV Size 15.49 GiB / not usable 22.88 MiB Allocatable yes PE Size 32.00 MiB Total PE 495

And i can use it : [root@c7-pxe-install ~]# lvextend -L +640M vg0/lvRoot Extending logical volume lvRoot to 13.47 GiB Logical volume lvRoot successfully resized

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.

Just want to mention that this behaviour is already known bug
