I have two webservers running debian 7 (stable) with software RAID1 and DRBD 8.3.11.
On both servers there are the following shares, which should be connected:
On stella: /dev/md4 919014380 204664 872126436 1% /srv
On laura: /dev/md4 442143360 153168996 266514700 37% /srv
Later, the data of laura should be syncronized on /dev/drdb1.
The conf-file looks like:
resource r1 {
on stella {
device /dev/drbd1;
disk /dev/md4;
address 192.168.1.1:7789;
meta-disk /dev/sdb3[0];
}
on laura {
device /dev/drbd1;
disk /dev/md4;
address 192.168.1.2:7789;
meta-disk /dev/sdb2[0];
}
}
If I try to attach...
root at stella:/srv# drbdadm attach r1
--== Thank you for participating in the global usage survey ==--
The server's response is:
node already registered
1: Failure: (104) Can not open backing device.
Command 'drbdsetup 1 disk /dev/md4 /dev/sdb3 0 --set-defaults --create-device --on-io-error=detach' terminated with exit code 10
Could anybody help me please?
Martin.
