Thanks, Roland,
but it seems impossible to configure with drbdmanage a complete mesh
configuration with 2 interfaces (cross patch) for each node.
Here below the mails with Petra Trunner that confirmed me the manual
config is right. Must I connect the 3 nodes with only 1 interfaces
and the use of switches?
Regards,
Michele

Hi Michele,
yes, that's the right way how you've done it.
To your last question: not yet, but very soon.
Did you know? We have a DRBD mailing list
http://lists.linbit.com/mailman/listinfo/drbd-user
There, you can register and also take a look at the linked archive.
Regards,
Petra

Re: DRBD - your request
Dear Petra,
thank you for your reply, and I'm sorry to disturb you again, but in
the userguide you suggested I cannot find how to configure the
connection as indicated in DRBD9 userguide PDF at point 5.8 for
complete mash (I have 3 servers each one with 2 NICs dedicated to
DRBD, connected with cross cables.
Must I modify manually the drbdctrl.res created by DRBDmanage, adding:
# mpve1-2 have crossover links like 192.168.65.x
connection {
host mpve1 address 192.168.65.135 port 7012;
host mpve2 address 192.168.65.136 port 7021;
}
# mpve1-3 have crossover links like 192.168.67.x
connection {
host mpve1 address 192.168.67.135 port 7013;
host mpve3 address 192.168.67.137 port 7031;
}
# mpve2-3 have crossover links like 192.168.66.x
connection {
host mpve2 address 192.168.66.136 port 7023;
host mpve3 address 192.168.66.137 port 7032;
}
or there is a method with DRBDmanage (not clearly specified in the manual?
Thanks again for your kindness,
have a nice day,
Michele
Dear Michele,
I wouldn't create such cluster's config by hand, therefor we created
DRBDmanage. Have a look at the setup guide, it makes adding those nodes
to your cluster much easier than it was before:

Kind regards,

Hi all,
Here below the drbdctrl.res, manually configurated regarding connections:
No. You are not supposed to touch any resource files drbdmanage
generates, especially not the one it uses for its cluster database (aka
the control volume). These files get overwritten.
nodea:$ drbdmanage init IP_OF_INTERFACE_FOR_CLUSTER_COMMUNICATION
nodea:$ drbdmanage new-node nodeb NODEBIP
nodea:$ drbdmanage new-node nodec NODECIP
If you want to make life easy, ssh-copy-id nodea's ssh key to nodeb and
nodec.
