Hi again,

Well, I don't know what is this /var/lib/drbd directory, but here is a patch in order to take in account the "make PREFIX=" command

Tell me if it is OK for you.

And so, last question, what is the aim of this directory ? I have seen drbdadm create symbolic link to the configuration file, but why ?

Hi !
On a test machine, DRBD 8.2.5 was running, built from source with "make all && make install" Configuration file is /usr/local/drbd-8.2.5/etc/drbd.conf
DRBD module is /lib/modules/uname -r/kernel/drivers/block/drbd.ko
User DRBD tools drbd{adm|meta|setup}are in /sbin
I have got a symbolic link /usr/local/drbd -> /usr/local/drbd-8.2.5
Then I stop DRBD, put the 8.3.0 source in /usr/local/drbd-8.3.0 and replace the symbolic link /usr/local/drbd -> /usr/local/drbd-8.2.5 with /usr/local/drbd -> /usr/local/drbd-8.3.0 I have built DRBD 8.3.0 from source with "make PREFIX=/usr/local/drbd all && make PREFIX=/usr/local/drbd install".
Configuration file is in /usr/local/drbd-8.3.0/etc/drbd.conf (same as before)
DRBD module is /usr/local/drbd-8.3.0/lib/modules/`uname
-r`/kernel/drivers/block/drbd.ko
User DRBD tools drbd{adm|meta|setup}are in /usr/local/drbd-8.3.0/sbin
At the installation I can see a new empty directory: /usr/local/drbd-8.3.0/var/lib/drbd
What is this new directory ?
Old module is always installed in /lib/modules/uname -r/kernel/drivers/block/drbd.ko but not used. Now I use insmod /usr/local/drbd-8.3.0/lib/modules/uname -r/kernel/drivers/block/drbd.ko and /proc/drbd show me 8.3.0 PATH=/usr/local/drbd/sbin:$PATH in order to get first the new user tools
Starting DRBD 8.3.0, using the resource defined under the 8.2.5 version, all is OK, but when I issue the following commands, I have got:

So, I think my symbolic link /usr/local/drbd -> /usr/local/drbd-8.3.0 is the problem, but I don't understand why ?
I can't find any information about this new var/lib/drbd directory. Thank in advance for any clue.
If it can help, here is my /usr/local/drbd/drbd.conf
