My first question/explanation would be that you filled up the snapshot device. This is quite possible, as a yum install involves creating several copies of the actual files you end up installing. The way to see if this is what is happening would be to have another terminal open, and periodically watch the output of "dmsetup status". As new blocks are written to the rootfs snapshot device, you will see the snapshot filling up. If you get these IO errors even before the snapshot fills up, please try to post some more detailed output. In general, as discussed there are pros and cons with this method, and a unionfs method. I do think there are ways to work around the cons of this method in such a way that it is useful. For instance, I'll play around and see if I can prescribe a process of using yum that will get it to create all of its intermediate files in a native tmpfs (/dev/shm or the like) instead of the rootfs, so that they don't eat into the snapshot space. Likewise, now that I have my first actual tester, maybe I'll figure out some other creative ways to improve the method (I have some ideas I need to experiment with...).
