It is a kernel problem, and not limited to LVM.  You need to log
in directly as root (no "su -") so that you don't have any ulimit
set for your shell.  Block devices moved into the page cache in
2.4.10, and were (incorrectly) affected by file size limits.  This
is fixed in 2.4.17-pre(something), or there is a patch to fix this
also (search for "setrlimit" on l-k).
