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@alpha:~# drbdmanage nodes Waiting for server: ............... No nodes defined root@alpha:~# drbdmanage ping pong root@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@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@alpha:~# drbdmanage nodes Waiting for server: . +------------------------------------------------------------------------------------------------------------+ | Name | Pool Size | Pool Free | | State | |------------------------------------------------------------------------------------------------------------| | 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
