Hi all,
I am trying to setup 3-node cluster but constantly one of the nodes fail
to sync with master. Here is what I do:
1. I create 3 VMs with CentOS 7.2 minimal (`3.10.0-327.el7.x86_64`)
2. I install DRBD9 RPMs I have built myself from following tags: drbd:
9.0.9, drbd-utils: 9.1.0, drbdmanage: 0.99.10
3. I setup SSH passwordless authentication between all 3 nodes
4. I setup hostname and add all hostnames to /etc/hosts on each node
5. On master, I run `drbdmanage init [MASTER_IP]`
6. On each slave I run `drbdmanage add-node [SLAVE_HOSTNAME] [SLAVE_IP]`
...and what happens is that first slave synchronizes with master
properly but the second one hangs in "Connecting" state and is marked on
master as "StandAlone":
.drbdctrl role:Primary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
node-10-9-4-137 role:Secondary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
node-10-9-4-192 connection:StandAlone
According to user's guide, this should work out-of-the-box but somehow
it doesn't. Am I missing something? Should I do some pre-setup that's
not mentioned in the user's guide?
I've collected output from drbdadm, drbdsetup, dbus-monitor --system and
syslog, if anyone would be willing to help me with this I have put the
logs on github:
- master:
https://github.com/localghost/issues/tree/master/drbd/node_does_not_sync/before_adjust/10.9.4.119/logs
- slaves:
* successful:
https://github.com/localghost/issues/tree/master/drbd/node_does_not_sync/before_adjust/10.9.4.137/logs
* failing:
https://github.com/localghost/issues/tree/master/drbd/node_does_not_sync/before_adjust/10.9.4.192/logs
Thanks,
Zbigniew Kostrzewa
