[linux-lvm] can't make new filesystems?



LVM 1.0.3 on redhat linux 7.3 (2.4.18-3 kernel) on DELL PowerEdge 4600.

I'm cutting and pasting my whole problem below, sorry for the size, but
I'll describe it here in short:

Every time I remove a logical volume, I am then unable to create any new
filesystem within that volume group. The only way I can create another
filesystem is to blow away the VG and recreate it, then the problem is
fixed. The text below shows how I started with a good VG and 3 LV's in
that VG, then removed the LV, recreated an LV, tried to make a filesystem
on it and got an error. In fact I can't make any filesystem on the VG
anymore.

Any ideas? I'm doing it per the man pages, and the LVM manual I downloaded
from sistina.

I hope I can get this working, because if this is some bug, then there is
no way we can rely on it. But I must be doing something wrong, there is no
way something this bad could be a bug.

Thanks in advance,

Alex
