[DRBD-user] drbd can not connect to the other peers after a hardware crash

[Denis Alligand]

Hello Everyone,


I was trying to make some test on drbd after a dister recovery.

i have the following problem:

When i simulate an hardware crash (bassically by swiching off the power),
when the server gies up again, it is unable to connect to the other peers
still alive.


My configuration:

2 Dell Poweregde 2950 with perc6 raid 1systeme (2*300 G SAS 15K HD)


Version:

 cat /proc/drbd
version: 8.0.11 (api:86/proto:86)
GIT-hash: b3fe2bdfd3b9f7c2f923186883eb9e2a0d3a5b1b build by root at marion,

as you can see the peer in unknow state but i have no way to have it back to
a uptodate or inconsitent state.

at boot up time I have the nasty message that tells me the server is waiting
for another peers, but i am sure the peers is up and running.

Even when i boot both node at the same time i can not connect them together.

Of course it uses to work with the same configuration,

no problems occurs when i made a hearbeat stop on one node or when i plugged
of the network cable, it only happened when i made a hardware crash.

I want to have it back again, i tested on another 2 servers ans the only way
i found so far was to format enre-install the server.

i guess there is a lock somewhere, but i have no clue where to find.

Any help?

configuration is quite simple:

global {
  usage-count yes;
}
common {
  protocol C;
}
resource r0 {
   syncer { rate 60M; }
  on karine {
    device    /dev/drbd1;
    disk      /dev/sda4;
    address   192.168.0.3:7789;
    meta-disk /dev/sda3[0];
  }
  on marion {
    device    /dev/drbd1;
    disk      /dev/sda4;
    address   192.168.0.4:7789;
    meta-disk /dev/sda3[0];
  }
}



regards,

Denis
