Hi,
Can someone help me understand the following situation? I have 3 nodes
using DRBD9 with one node added without storage.
Now, on the two hosts with storage I have this:
[root@server2-drbd ~]# drbdadm status
.drbdctrl role:Secondary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
drbd-mon role:Secondary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
server3-drbd role:Primary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
res1 role:Primary
disk:UpToDate
server3-drbd role:Secondary
peer-disk:UpToDate
[root@server3-drbd ~]# drbdadm status
.drbdctrl role:Primary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
drbd-mon role:Secondary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
server2-drbd role:Secondary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
res1 role:Secondary
disk:UpToDate
server2-drbd.blinc.co role:Primary
peer-disk:UpToDate
I would like to understand why, on server2, .drbdctrl role is secondary and
res1 role is primary, while on server3 .drbdctrl role is primary and res1
role is secondary.
I can switch res1 primary role between server2 and server3 without problems
but I can't do anything about .drbdctrl. Trying to change the role to
secondary on server3 doesn't return any error but it's just not happening.
Thanks,
Daniel
