[linux-lvm] configuration question

[linux-lvm] configuration question

[Steven Lembark]

trying to get vg's out of dev for now -- devfs issues.

so i modify ./kernel/lvm.h replacing:

	#define LVM_DIR_PREFIX  "/dev/"

with 
	#define LVM_DIR_PREFIX  "/lvm/"

then configure and compile the code.

probem is that this doesn't seem to purge /dev/ from
all of the code.  is there some other location where
the lvm directory is defined or is this just a 
configuration bug [perhaps a known one at that]?

thanx.

It looks like there are few hardcoded /dev strings elsewhere
in the code. try a grep down the lib directory and change 
those too. I'll fix this in CVS.

The only one I still found was in tools/lib/pv_check_name.c.
Fixed that and checked it in.

The real constraint here is, that LVM stores the full pathname in the VGDA
and that there's no tool available today to change that information on the fly.

I implemented LVM_DIR_PREFIX a while ago as a helper to ease namespace
changes. But for sure there's still something to do (as it always will ;-)

i don't have any existing VG's -- problems with devfs trashed
them all.  main issue now is starting over w/ lvm & devfs in
separate namespaces until all of the kinks are worked out.

All right.
In this case you should give it a (not tested!) try with the recent change.

Please retrieve the software from the CVS repository by following the
instructions on our WEB site <www.sistina.com>.

Don't forget to apply the tag "LVM_0-9-patches" during checkout.
