Hi guys,
First of all: I'm really impressed with DRBD9, so good job!
My problem: drbdmanage completely breaks when one of the two nodes is down. Drbdadm commands still work perfectly fine (and I can still mount the LVs hosted on the online node).
My setup is quite simple: two Ubuntu 16.04 nodes using DRBD9, using drbdmanage (0.99.2. From the Linbit PPA.
After shutting down node bravo:
root at alpha:~# drbdmanage nodes
Waiting for server: ...............
No nodes defined
root at alpha:~# drbdmanage ping
pong
root at alpha:~# drbdadm status
.drbdctrl role:Secondary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
bravo connection:Connecting
volume1 role:Secondary
disk:UpToDate
bravo connection:Connecting
volume2 role:Secondary
disk:UpToDate
bravo connection:Connecting
I have not made .drbdctrl primary as Robert said here: http://lists.linbit.com/pipermail/drbd-user/2016-June/023002.html.
After starting the bravo node again:
root at alpha:~# drbdadm status
.drbdctrl role:Secondary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
bravo role:Secondary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
volume1 role:Secondary
disk:UpToDate
bravo role:Secondary
peer-disk:UpToDate
volume2 role:Secondary
disk:UpToDate
bravo role:Secondary
peer-disk:UpToDate
root at alpha:~# drbdmanage nodes
Waiting for server: .

| alpha | 51196 | 49132 | | ok |
| bravo | 51196 | 49132 | | ok |
+------------------------------------------------------------------------------------------------------------+
TLDR: drbdmanage completely breaks while drbdadm commands still work (including mounting LVs) when one of the two nodes is down.
Is there anyone who can point me in the right direction?
Kind regards,
Gerwim Feiken
