My understanding is that snapshot creation involves a brief period when I/O to the origin LV is suspended: if lvcreate needs to page in something from that device, or needs to read, say, /etc/lvm/lvm.conf, or something, you'll get a deadlock. (Mind you this all seems fixable to me: before suspending, mlockall() lvcreate in memory, touch all its pages to force pagein, and do all other reading required. But I guess this just hasn't been done yet.) -- `He accused the FSF of being "something of a hypocrit", which shows that he neither understands hypocrisy nor can spell.' --- jimmybgood _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
