CentOS 7 / RedHat 7 pxe boot fails with “ValueError: new value non-existent xfs filesystem is not valid as a default fs type”

Error:

When I tried to install a CentOS 7 server via pxe/netboot today, I encountered the following error:

ValueError: new value non-existent xfs filesystem is not valid as a default fs type

Pane is dead

Solution:

Use kernel, initrd and distribution files of the same release/update version.

Description:

This has nothing to do with the filesystem but with a difference between the kernel / initrd used for booting and the rest of the distribution. We keep the kernel and initrd files for tftpboot in a different directory then the distribution files. The distribution files got updated but the vmlinuz and initrd.img files in the separate directory did not, causing this error.

Error Linux

For me, the same error appeared because someone had added “xfs.blacklist=yes” to the kernel boot parameters in /tftpboot/pxelinux.cfg/default.

The only clue was found in dmesg on the half-booted machine.
