I just tried rebooted that machine. The LVM setup seems mangled and it doesn't boot successfully. On #lvm on irc.freenode.net I was told that the kernels in Fedora don't yet support snap-shot which is the cause of the problem. I have been told that the lvm utility programs in FC3T1 correctly detect this (and presumably don't break the system). -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
