DRBD - block device replication solution for HA cluster mainly
one of the choices for SDS
I am a member of openSUSE Japanese user group. I was openSUSE.Asia Summit 2017 local committee and 2018 global committee. I introduced Portus in Japanese Open Source Conference Tokyo 2018 spring and some articles. I also introduced Kubic. I am using openSUSE in my house since openSUSE 13.1.
No video of the event yet, sorry!
This talk explains HA cluster used by DRBD. DRBD is block device replication software developed by LINBIT and licensed by GPLv3. HA cluster is usually an expensive fee for device and controller software. DRBD can make HA cluster low cost because it is opensource and can use general devices.
Volumes can become the single point of failure. but DRBD can cover it. and we can use it by manage controllers like drbdmanage or LINSTOR. LINSTOR has not been yet supported in openSUSE. but, LINBIT quitted development of drbdmanage. and announced developing LINSTOR. so I explain LINSTOR to provision HA cluster. I wish openSUSE will support LINSTOR. and I think basic philosophy is same.
HA cluster used by DRBD is more usable. DRBD can use with pacemaker and Corosync, with kubernetes. and more. this talk introduces them. pacemaker and Corosync can manage clusters. pacemaker and Corosync change active node when detecting a failure. DRBD support kubernetes by Kubernetes Flex Volume plugin.
I remark easy step to setup HA cluster with DRBD. so attendee can learn how to setup HA cluster with easy way and HA cluster background philosophy.
