Well, I observed inexplicable resets of a node when partner was rebooted in twp node cluster with qdevice. No timers were changed. I have not investigated it in more details because first I could not find out was conditions triggered it and later I decided to use SBD with shared block device instead which seems to mostly work. According to manual page default for dpd_interval is 10 seconds (10000ms). So should not defaults be changed then? > Honza > > > > for pacemaker: pcs quorum device add sync_timeout=60000 timeout=20000 model > > net host=‘witness' algorithm=ffsplit > > > > Also I set -I 60 option (net timeout) to sbd. > > > > But effect is still exists: > > > > Logs, after one of the nodes «tuchanka1a» was powered off in 17:13:53. > > > > From server 'witness' with qnetd: > > > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug Client > > ::ffff:192.168.89.12:39144 (cluster krogan1, node_id 2) sent membership > > node list. > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug msg seq > > num = 7 > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug ring id = > > (2.4c) > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug > > heuristics = Undefined > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug node list: > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug node_id > > = 2, data_center_id = 0, node_state = not set > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug ffsplit: > > Membership for cluster krogan1 is not yet stable > > Aug 8 17:13:55 witness corosync-qnetd: Aug 08 17:13:55 debug Algorithm > > result vote is Wait for reply > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug Client > > ::ffff:192.168.89.12:39144 (cluster krogan1, node_id 2) sent quorum node > > list. > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug msg seq > > num = 8 > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug quorate = > > 0 > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug node list: > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug node_id > > = 1, data_center_id = 0, node_state = dead > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug node_id > > = 2, data_center_id = 0, node_state = member > > Aug 8 17:14:55 witness corosync-qnetd: Aug 08 17:14:55 debug Algorithm > > result vote is No change > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 warning Client > > ::ffff:192.168.89.11:47456 doesn't sent any message during 40000ms. > > Disconnecting > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug Client > > ::ffff:192.168.89.11:47456 (init_received 1, cluster krogan1, node_id 1) > > disconnect > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug ffsplit: > > Membership for cluster krogan1 is now stable > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug ffsplit: > > Quorate partition selected > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug node list: > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug node_id > > = 2, data_center_id = 0, node_state = not set > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug ffsplit: No > > client gets NACK > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug Sending > > vote info to client ::ffff:192.168.89.12:39144 (cluster krogan1, node_id 2) > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug msg seq > > num = 2 > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug vote = ACK > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug Client > > ::ffff:192.168.89.12:39144 (cluster krogan1, node_id 2) replied back to > > vote info message > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug msg seq > > num = 2 > > Aug 8 17:15:00 witness corosync-qnetd: Aug 08 17:15:00 debug ffsplit: > > All ACK votes sent for cluster krogan1 > > Aug 8 17:17:00 witness corosync-qnetd: Aug 08 17:17:00 warning Client > > ::ffff:192.168.89.12:39144 doesn't sent any message during 40000ms. > > Disconnecting > > Aug 8 17:17:00 witness corosync-qnetd: Aug 08 17:17:00 debug Client > > ::ffff:192.168.89.12:39144 (init_received 1, cluster krogan1, node_id 2) > > disconnect > > Aug 8 17:17:00 witness corosync-qnetd: Aug 08 17:17:00 debug ffsplit: > > Membership for cluster krogan1 is now stable > > Aug 8 17:17:00 witness corosync-qnetd: Aug 08 17:17:00 debug ffsplit: No > > quorate partition was selected > > Aug 8 17:17:00 witness corosync-qnetd: Aug 08 17:17:00 debug ffsplit: No > > client gets NACK > > Aug 8 17:17:00 witness corosync-qnetd: Aug 08 17:17:00 debug ffsplit: No > > client gets ACK > > > > From other node ‘tuchanka1b’.
