I am having trouble getting lvcreate to work.
I've been able to create the PV and VG, but lvcreate always core dumps with a
seg fault. I've confirmed that I have the same code level in the
kernel and tools (1.0.1-rc4). I've tried compiling the tools with gcc
(v2.96) and egcs (v2.91.66), but both fail. I'm running a 2.4.14 kernel,
lvm as a module, and glibc-2.2.4-19.
The problem seems to be with a corrupt lvol
name from what I see in the gdb output I've attached.
Any help would be great.
