Hi DRBD gurus, I have used drbd for a while and but I have not played with it extensively.
I want to retire a machine configured as secondary node for drbd and configure a new server instead, which is basically similar to "Dealing with permanent node failure". Since these machine have live data, I want to be extra cautious about reconfiguring this. Here are the steps that I will do, please let me know if there is any mistake anything missing in the procedure. I am running drbd 8.3.8 on CentOS 5.6 systems. 1. On secondary node, stop the drbd processes /etc/init.d/drbd stop 2. On the primary node, modifying /etc/drbd.conf of new nodes IP and disk backends re-configuring/re-starting the firewall (iptables) to allow new node for drbd traffic reloading drbd for the new configuration file. /etc/init.d/drbd reload 3. On the new node, copy the /etc/drbd.conf file from primary host modify and restart firewall load drbd kernel module, preparing disks corresponding to the /etc/drbd.conf initializing disks, drbdadm create-md resource0 drbdadm attach resource0 drbdadm syncer resource0 drbdadm connect resource0 and for resource1, ... Is there anything missing or wrong above? Thank you very much for your help. -- Zhi-Wei Lu Bioinformatics Core Genome Center University of California, Davis (530) 752-2698 _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
