RHEL 7.x: KickStart LVM provisioning issues
I have created a customized kickstart script to dynamically provision disk(s) based on some simple logic & a template. The errors are as follows: 'Unable to allocate requested partition scheme.' Please see attached screen shots at bottom of post to see that all disks are selected.
Looking at the anaconda.log It seems that errors start immediately following the 'is_valid_stage1_device(sda)' function call (which returns 'true').
stage1 device cannot be of type lvmvg
stage1 device cannot be of type lvmlv
I know some of the anaconda API has changed;
- A breaking change in 6.7 introduced issues with using --percent & --grow without the use of --size
- A regression bug affected the same configuration parameters in 7.0
This is experienced with RHEL versions 7.0, 7.1 & 7.2. The configuration shown below works fine with 6.5, 6.6 & 6.7.
Am I missing something in the API for LVM partitions? Any help, tips & resources is appreciated.
The following /tmp/disks configuration file is created based on the number of physical disks & system information with %include /tmp/disks.
# Zero the MBR zerombr # Clear out partitions for sda clearpart --all --initlabel --drives=sda # Create a /boot partition on sda of 500MB part /boot --size=500 --fstype="ext4" --ondisk=sda # Create an LVM partition of 172337MB on sda part pv.root --size=172337 --ondisk=sda --grow --asprimary # Create the root volume group volgroup rootvg --pesize=4096 pv.root # Create a memory partition of 31962MB logvol swap --fstype="swap" --name="swaplv" --vgname="rootvg" --size=31962 # Create logical volume for the / mount point logvol / --fstype="ext4" --name="rootlv" --vgname="rootvg" --size=102400 # Create logical volume for the /var mount point logvol /var --fstype="ext4" --name="varlv" --vgname="rootvg" --size=40960 # Create logical volume for the /export/home mount point logvol /export/home --fstype="ext4" --name="homelv" --vgname="rootvg" --size=10240 # Create logical volume for the /tmp mount point logvol /tmp --fstype="ext4" --name="tmplv" --vgname="rootvg" --size=2048 # Create new physical volume on sdb as pv.optapp.1 part pv.optapp.1 --size=78741 --grow --ondisk=sdb # Create new physical volume on sdc as pv.optapp.2 part pv.optapp.2 --size=100352 --grow --ondisk=sdc # Create new physical volume on sdd as pv.optapp.3 part pv.optapp.3 --size=100352 --grow --ondisk=sdd # Create new physical volume on sde as pv.optapp.4 part pv.optapp.4 --size=78741 --grow --ondisk=sde # Create a new volume group with all the physical volumes volgroup optappvg pv.optapp.1 pv.optapp.2 pv.optapp.3 pv.optapp.4 --pesize=4096 # Create a new logical volume for /opt/app mount point logvol /opt/app --fstype="ext4" --name="optapplv" --vgname="optappvg" --size=268639
Kickstart halts here
As you can see all disks are currently selected despite the error shown in the previous screen shot
When you look at the disks and what is valid for versions 6.5, 6.6 & 6.7 of RHEL enterprise they are all shown as not just being used but also that the root bootable partition is correct.
And a the error message is less than informative about why it is failing
