[DRBD-user] DRBD 8.2.5 to 8.3.0 upgrade with make PREFIX=/usr/local/drbd error: symlink(/usr/local/drbd/etc/drbd.conf, /var/lib/drbd//drbd-minor-1.conf): No such file or directory

[GAUTIER Hervé]

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

   syncer {
      rate 31M;
   }
}

resource drbd_resource1 {
   protocol C;

   syncer {

   disk {

   }
}
