Kickstarting a JFS partition install in SL6.1

[mattward2k]

I'm attempting to cobble and kickstart a JFS partition for a KVM guest running SL6.1 on a host that runs SL6.1, in the same way I would ext4 or XFS. I'm using part and logvol to create partitions and logical volumes under LVM and simply setting --fstype=jfs; this works fine for ext4 or XFS but during the cobbled install on the guest, anaconda hangs at "Creating jfs filesystem on /dev/mapper/vg_main-lv_main". Does KVM require the host OS to have the JFS tools installed (i.e. mkfs.jfs) in order to format the partition as JFS, or is this just not possible through cobbler/kickstart, and will require downloading and installing the JFS tools after full OS installation and reformatting at that stage?

JFS is not installed in 6.x by default. You need to install the kernel sources and alter your configuration to add jfs file system support, then build and install the kernel. I had to do that myself in order to handle jfs file systems on some embedded boards that I support.
