Description Steve Hémond 2004-07-02 08:14:23 UTC
With dm-mod compiled in kernel, lvm2 tools (vgscan and vgcreate in my case) causes segmentation faults.

* Note that when using dm-mod as a module, it works smoothly.

Reproducible: Always
Steps to Reproduce:
1. Compile dm-mod in kernel (device mapper)
2. Emerge lvm2
3. Run vgscan

Actual Results:  
Segmentation Fault

Expected Results:  
vgscan should returns volume groups found.
vgcreate should create a volume group.

Kick it

I just went through the same thing on x86... would segfault when compiled in, but worked fine as a module.
