RE: [dm-devel] /dev/dm-? and /dev/mapper/



device-mapper creates the /dev/dm-? names, I doubt you could get rid of
them.
LVM names are persistent, maybe instead of mount-by-label you could
change to mount the persistent /dev/VGname/LVname's

Subject: [dm-devel] /dev/dm-? and /dev/mapper/

Hi,

I don't know if this is the right place to ask ...

I use kernel 2.6.22 and debian etch.

If I create a vg and some volumes in it I get the

/dev/dm-?

and

/dev/mapper/<vg>-<lv>

devices nodes.

If I try to mount the filesystem via label, sometimes /dev/dm-? and 
sometimes /dev/mapper/<vg>-<lv> gets mounted.

That is the cause of some later errors in my setup.

The question is: how can I get rid of the dm-? (e.g. they should not 
be created at all) oder how do I the mount to stick to 
the /dev/mapper/... files?

TIA,
