From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2+) Gecko/20010706 Description of problem: You would expect clearpart --all to work regardless of the current contents/condition of the boot sector. It doesn't. For example: cat /var/log/messages > /dev/hda; sync; reboot -f -n dd if=/dev/urandom of=/dev/hda bs=4086 count=50; sync; reboot -f -n Will make it so a clearpart --all will not work correctly. How reproducible: Always Steps to Reproduce: 1. Screw up the boot sector 2. Reboot and try to do a kickstart with clearpart --all Additional info: Here is my workaround in my kickstart.ks: %pre # Fix complaining anaconda about foobared partition table # you would think that "clearpart --all" would take care # of it, but it doesn't, so here is the workaround mknod /dev/hda echo -e "d\n4\nd\n3\nd\n2\nd\n1\nw\n" | fdisk /dev/hda
Right. clearpart --all only affects the partitions on the disk...not the master boot record. I think what you are looking for is the 'zerombr yes' tag. This should reinitialize the boot record. Refer to http://www.redhat.com/support/manuals/RHL-7.1-Manual/customization-guide/s1-kickstart2-options.html for more information about zerombr.
I am using "zerombr yes" as well, eg: zerombr yes clearpart --all Red Hat 7.0 and earlier worked fine, this is a new change with 7.1.
Jeremy check this against our current tree please.
This works fine in our current tree.
