Hello, Follow up. I think this is possible in Red Hat Enterprise Linux itself. Might be working itself in Fedora as well, See the following steps. [root@localhost ~]# lvm lvm> pvcreate /dev/vdc Physical volume "/dev/vdc" successfully created lvm> vgcreate newvg /dev/vdc Volume group "newvg" successfully created lvm> lvcreate -L 100M -n pushpendra newvg Logical volume "pushpendra" created lvm> exit Exiting. [root@localhost ~]# lvdisplay --- Logical volume --- LV Path /dev/newvg/pushpendra LV Name pushpendra VG Name newvg LV UUID Lmjbtf-gR5p-11yG-7V4w-hI81-jl3O-Itb7Kd LV Write Access read/write LV Creation host, time localhost.localdomain, 2014-07-03 12:47:26 -0600 LV Status available # open 0 LV Size 100.00 MiB Current LE 25 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2 [root@localhost ~]# pvdisplay --- Physical volume --- PV Name /dev/vdc VG Name newvg PV Size 8.00 GiB / not usable 4.00 MiB Allocatable yes PE Size 4.00 MiB Total PE 2047 Free PE 2022 Allocated PE 25 PV UUID h0WL7R-ld25-A1ak-aR7Q-UmL8-ZJQE-9KsHGZ [root@localhost ~]# vgdisplay --- Volume group --- VG Name newvg System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 2 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 8.00 GiB PE Size 4.00 MiB Total PE 2047 Alloc PE / Size 25 / 100.00 MiB Free PE / Size 2022 / 7.90 GiB VG UUID 6Nl6md-dfu4-Cvai-rEZv-1hI7-XVn1-cEgWEh If the lvm commands are used in %pre script, It will work. - Pushpendra This works from kickstart with 'part pv.02 --onpart=vdb'. The following was used to create PV /dev/vdb on a libvirt (KVM) VM, RHEL 6.6. host: # cat /var/www/html/ks6.cfg ... # Partition Information zerombr part /boot --fstype=ext4 --size=100 --asprimary --ondisk=vda part pv.01 --size=100 --grow --asprimary --ondisk=vda volgroup vg00 pv.01 logvol swap --vgname=vg00 --size=512 --name=swap --fstype=swap logvol / --vgname=vg00 --size=4096 --name=root --fstype=ext4 part pv.02 --onpart=vdb volgroup appvg pv.02 logvol /app --vgname=appvg --size=1024 --name=applv --fstype=ext4 --grow --fsoptions="defaults,noatime" ... # virt-install -n vm8 -r 1024 --vcpus 1 --disk /VirtualMachines/vm8.img,size=8 --disk /VirtualMachines/vm8-1.img,size=2 -l http://download.devel.redhat.com/released/RHEL-6/6.5/Server/x86_64/os/ -x "ks=http://192.168.122.1/ks6.cfg" [root@localhost ~]# pvs PV VG Fmt Attr PSize PFree /dev/vda2 vg00 lvm2 a-- 7.88g 3.38g /dev/vdb appvg lvm2 a-- 1.97g 0 [root@localhost ~]# lvs LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert applv appvg -wi-ao---- 1.97g root vg00 -wi-ao---- 4.00g swap vg00 -wi-ao---- 512.00m This feature really seems to be present. My bad that I didn't find the way to implement this. Thanks to Donald for finding the better way. --onpart works great than that of --ondisk I confirmed that with the following kickstart file. ================================================================== install text cdrom lang en_US keyboard us network --bootproto dhcp onboot=yes zerombr bootloader --location mbr --driveorder=vda,vdb timezone America/Denver auth --enablemd5 --enableshadow selinux --disabled rootpw redhat firewall --disabled skipx clearpart --all --initlabel reboot part /boot --fstype=ext3 --size=200 --ondisk=vda part pv.01 --size=1000 --grow --ondisk=vda part swap --size=1000 --fstype=swap --ondisk=vda volgroup myvg pv.01 logvol /home --vgname=myvg --name=homevol --size=500 logvol / --vgname=myvg --name=rootvol --size=1000 --grow part pv.02 --onpart=vdb volgroup appvg pv.02 logvol /app --vgname=appvg --size=1024 --name=applv --fstype=ext4 --grow %packages @base -kexec-tools -NetworkManager ================================================================== And the output was as follows ================================================================== [root@localhost ~]# pvs PV VG Fmt Attr PSize PFree /dev/vda3 myvg lvm2 a-- 6.81g 0 /dev/vdb appvg lvm2 a-- 7.97g 0 [root@localhost ~]# vgs VG #PV #LV #SN Attr VSize VFree appvg 1 1 0 wz--n- 7.97g 0 myvg 1 2 0 wz--n- 6.81g 0 [root@localhost ~]# lvs LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert applv appvg -wi-ao---- 7.97g homevol myvg -wi-ao---- 512.00m rootvol myvg -wi-ao---- 6.31g . ================================================================== This makes me think that the Feature request is no more valid. - Pushpendra Chavan |
