In the article 'Learning Linux LVM, Part 2' (http://www.gentoo.org/doc/en/articles/lvm-p2.xml), there is a link at the bottom for the 'Linux LVM FAQ' (http://www.sistina.com/cgi-bin/lvm-faqprocessor.cgi). Unfortunately, the link now redirects to a page on the 'Red Hat Global File System' (http://www.redhat.com/en_us/USA/home/solutions/gfs/), which seems to have nothing at all to do with LVM. I don't know what the original page was like, so I'm not really sure what to suggest as an alternative. The closest thing I could find on google was the 'LVM 2 FAQ' sub-section (http://www.tldp.org/HOWTO/LVM-HOWTO/lvm2faq.html) of the LVM How-To, which is already linked.
Since I can't find the old site of any replacement either, I'm taking the link off the doc. Seems like RedHat brought out Sistina... http://www.eweek.com/article2/0,1895,1417646,00.asp a long time back.
Fixed in CVS, thanks for reporting.
