Re: [ClusterLabs] Antw: ringid interface FAULTY no resource move
I modify configuration of drbd but still nothing. I not mention the clusters are on hp blades machines. I plug out connection on switch by disabling port. But still nothing :( , maybe add something like this to crm will do? ocf:pacemaker:ping \ params host_list="172.17.10.81 172.17.10.89" multiplier=100 name=ping_d \ op monitor interval=5s timeout=5s \ meta target-role=Started Rafal #cat drbd.conf global { usage-count no; } common { syncer { rate 100M; } protocol C; handlers { fence-peer "/usr/local/lib/drbd/crm-fence-peer.sh"; after-resync-target "/usr/local/lib/drbd/crm-unfence-peer.sh"; } } resource b1 { startup { wfc-timeout 0; degr-wfc-timeout420; } disk {. on-io-error detach; fencing resource-only; } on csb01A { device /dev/drbd2; disk/dev/sda2; address 255.255.255.1:7791; meta-disk internal; } on csb01B { device /dev/drbd2; disk/dev/sda2; address 255.255.255.9:7791; meta-disk internal; } W dniu 2016-05-05 o 16:29, Ken Gaillot pisze: On 05/05/2016 07:43 AM, Rafał Sanocki wrote: for what? cluster working good when i stop pacemaker, resources go to second node, but when connection is lost nothing happend.

Once you use shared storage, databases, and such, the risk is much greater -- a reconciliation nightmare at best, complete data loss at worst.

Thank you very much, I'll try now to set up.
