kickstart configuration file

Description of problem:

Launched kickstart installation with partitioning scheme containing encrypted LVs (one of them for swap). All of the partitions/LVs are created as expected after installation, including encryption, however the swap LV isn't in use and there is no record for the swap LV in /etc/fstab.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 7.2

How reproducible:
Install Red Hat Enterprise Linux 7.2, create a PV containing: 1. LV for /, 2. encrypted LV for /home, 3. encrypted LV for swap (see the attached kickstart file)

Steps to Reproduce:
1.Install Red Hat Enterprise Linux 7.2 (see the attached kickstart file), create a PV containing: a) /boot (primary), b) LVM PV containing b1) LV for /, b2) encrypted LV for /home, b3) encrypted LV for swap (with the same passphrase for both LVs)

2. After reboot, check whether swap is in use (swapon -s)

3. Check the content of /etc/fstab

Actual results:
There is no record for the swap LV in /etc/fstab, nor is the swap LV active.

Expected results:
The swap LV should have been in use (should be listed in /proc/swaps or after running swapon -s) and there should have been a line describing the swap LV in /etc/fstab.

Additional info:
The same behavior could be seen as well with plain partitions (without LVM) - just comment out the logvol* and volgroup lines in favor of the part* lines in the kickstart config file.

I did a test install using Server ISO and according to kickstart, I have not found any issue that would lead to unused swap partition on encrypted LVM.

I would like to ask you for additional installation logs.

I used the kickstart you provided and on my test machine, the swap entry is in /etc/fstab as well as swapon -s returns:

Filename   Type       Size    Used  Priority
/dev/dm-3  partition  522236  0    -1

Hello Karel,

I did a test install again in my kvm setup and this time I've made one change in my kickstart file is, I have added '--passphrase=<password>' option as given below:

bootloader --append="rhgb quiet crashkernel=auto" --location=mbr --driveorder="sda" --boot-drive=sda
clearpart --all --initlabel
part /boot --fstype="ext4" --ondisk=sda --size=512
part pv.95 --fstype="lvmpv" --ondisk=sda --size=19967
volgroup VolGroup00 --pesize=4096 pv.95
logvol /  --fstype="ext4" --grow --size=10240 --encrypted --name=lv_root --vgname=VolGroup00 --passphrase=<redhat@123>
logvol swap  --fstype="swap" --size=512 --encrypted --name=lv_swap --vgname=VolGroup00 --passphrase=<redhat@123>

And I came across same issue. Please check below outputs from my test vm:

JFYI when I tested the same kickstart without '--passphrase' option then during the installation anaconda prompted for encryption passphrase and I got expected result. 

I am attaching anaconda logs when I faced this issue with '--passphrase' option in kickstart 'logvol' line. 

Let me know if you need anything from my end.

I was able to reproduce this after adding a passphrase to the logvol lines, and the patch from bug 1196200 fixes the issue. https://github.com/rhinstaller/anaconda/pull/659
