[linux-lvm] core dumped



Hello
I am having a lot of problems using a Redhat 7.1 with kernel 2.4.14 + lvm 1.0.1-rc4.


When I exec vgscan in my /var/messages a lots of "invalidate: busy buffer" strings appears.

Then, I do a "vgchange -ay" and I can create a PV and a VG. But at the moment that a exec lvcreate, it fails with a "core dumped".

Here are my logs:

root Homer sbin]# ./lvcreate -L948M -n test /dev/vol -v

What appears at /var/messages:


invalidate: busy buffer
invalidate: busy buffer
invalidate: busy buffer

Who can solve this problem???
What's the best kernel version to use with lvm???

Thanks!
