Sorry for the delayed reply Alexis, here's my DRBD conf global { usage-count no; } common { syncer { rate 15M; csums-alg sha1; al-extents 809; verify-alg sha1; } } resource r0 { protocol C; startup { degr-wfc-timeout 30; wfc-timeout 30; become-primary-on both; } disk { fencing resource-and-stonith; on-io-error detach; } handlers { fence-peer "/usr/lib/drbd/crm-fence-peer.sh"; after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh"; outdate-peer "/usr/lib/drbd/outdate-peer.sh"; split-brain "/usr/lib/drbd/notify-split-brain.sh root"; pri-on-incon-degr "/usr/lib/drbd/notify-pri-on-incon-degr.sh root"; pri-lost-after-sb "/usr/lib/drbd/notify-pri-lost-after-sb.sh root"; local-io-error "/usr/lib/drbd/notify-io-error.sh root"; } net { allow-two-primaries; cram-hmac-alg sha1; shared-secret "kalki"; after-sb-0pri discard-zero-changes; after-sb-1pri discard-secondary; after-sb-2pri disconnect; rr-conflict disconnect; } on server1 { device /dev/drbd0; disk /dev/sda3; address 192.168.0.92:7788; meta-disk internal; } on server2 { device /dev/drbd0; disk /dev/sda3; address 192.168.0.93:7788; meta-disk internal; }}
And I changed the OCFS2 configuration (Threshold=16 and idle=10secs time) which reduced my switch over time to 55secs when a primary node goes down. Not sure if this is correct, but it works :) Let know if anyone knows a better solution for reducing the switch over time.
