[dm-devel] LVM Multipathing

[shahid shaikh]

I tried it previously and now also. But it doesnt get me out of trouble.

That's why i tried the 1st FAQ. 
Can you please elaborate what can be wrong in all this stuff?

Thanks and Regards, 
Shahid Shaikh.

I was thinking about that part :

---


      3. LVM2 doesn't see my multipathed devices as PV, what's up ?

By default, lvm2 does not consider device-mapper block devices (such as 
a dm-crypt device) for use as physical volumes.

In order to use a dm-crypt device as an lvm2 pv, add this line to the 
devices block in /etc/lvm/lvm.conf:

types = [ "device-mapper", 16 ]

If /etc/lvm/lvm.conf does not exist, you can create one based on your 
current/default config like so:

lvm dumpconfig > /etc/lvm/lvm.conf

(tip from Christophe Saout)

... then again,

"you need to exclude the paths from the scaning"
