Hi Felix,
Thanks for the suggestion. I have removed all of the target-* parameters, however this behavior is still present when failing over with the DRBD device. I did notice the following line in the log when attempting to failover: Jan 30 15:11:15 node2 lrmd: [1440]: info: RA output: (p_drbd_mount2:1:notify:stdout) drbdsetup 1 syncer --set-defaults --create-device --rate=1000M Jan 30 15:11:15 node2 crmd: [1443]: info: send_direct_ack: ACK'ing resource op p_drbd_mount2:1_notify_0 from 120:428:0:f84ff0aa-9a17-4b66-954d-8c3011a3441e: lrm_invoke-lrmd-1327957875-58 Jan 30 15:11:15 node2 crmd: [1443]: info: process_lrm_event: LRM operation p_drbd_mount2:1_notify_0 (call=79, rc=0, cib-update=0, confirmed=true) ok Jan 30 15:11:15 node2 kernel: [ 1075.519415] block drbd0: conn( WFBitMapS -> SyncSource ) pdsk( Outdated -> Inconsistent ) Jan 30 15:11:15 node2 kernel: [ 1075.519441] block drbd0: Began resync as SyncSource (will sync 0 KB [0 bits set]).

The node simply stays as slave, even though it is the only online node. Attempting to cleanup the ms_drbd_mount1 primitive does not resolve the situation, however I could set the DRBD device as primary using drbdadm primary mount1. After doing so I could then use cleanup ms_drbd_mount1 and it resumed bringing up the rest of the resources successfully.

Is there some pacemaker utility that gives more verbose information on why a resource fails to start? What does the digit after the resource indicate, e.g. the :1 or :1_stop_0 below: Master/Slave Set: ms_drbd_mount2 [p_drbd_mount2] p_drbd_mount2:1 (ocf::linbit:drbd): Master node2 (unmanaged) FAILED Slaves: [ node1 ] Failed actions: p_drbd_mount2:1_stop_0 (node=node2, call=94, rc=-2, status=Timed Out): unknown exec error Thanks, Andrew ----- Original Message ----- From: "Felix Frank" < [email protected] > To: "Andrew Martin" < [email protected] > Cc: "drbd-user" < [email protected] > Sent: Monday, January 30, 2012 3:07:08 AM Subject: Re: [DRBD-user] Removing DRBD Kernel Module Blocks Hi, On 01/29/2012 03:03 PM, Lars Ellenberg wrote: >>> I don't think DRBD should attempt to become primary when >>> > > you issue a stop command/ > And it does not.

Hum, difficult. I can't really tell the problem from what you posted. >From experience: Your config contains lots of "target-role" etc. parameters (probably from issuing crm resource start / promote ...). I have known some of these to prevent clean failovers under specific circumstances. You may want to try and get rid of all those target-* parameters as a first try. HTH, Felix
