This is related to escalation CSO-30344. While testing Anaconda installation for Titanium Server, we found that if the disk has gpt partitions and 4K sectors, wipefs gets suck in an infinite loop, resulting in the installation hanging indefinitely. This is due to a known wipefs issue: https://bugzilla.redhat.com/show_bug.cgi?id=1145312 More details are also available at: http://www.spinics.net/lists/util-linux-ng/msg09932.html ** This was tested with Anaconda version in WRL6 RCPL13.
