Description Corey Marthaler 2007-07-13 19:43:00 UTC

Description of problem:
vgck fails just like any other lvm cmd when there is an actual corruption. So
what's the point of this cmd? 

[root@link-08 ~]# vgck helter_skelter

Corrupt a vg by writing over a pv in that vg:
[root@link-08 ~]# dd if=/dev/zero of=/dev/sdf1 count=1000
1000+0 records in
1000+0 records out
[root@link-08 ~]# sync

[root@link-08 ~]# vgck helter_skelter

I have another bz for vgck so I'll see if I can't make this command do something more useful in the near future.

Comment 2 Dave Wysochanski 2010-05-17 12:13:11 UTC

No upstream fix in rhel4 - moving to rhel5.
