Galera Cluster Gcache

[Yoong Kin Meng]

  Hi All,

if i setup a 3 nodes galera cluster for mariadb, let say node1, node2 & node3.

1. Node1 make transaction and commit

2. the transaction replicate to node2 and node3.

3. node3 apply successfully, however node2 suddenly reboot and havent apply.

4. let say node2 gcache.recovery=no, so when try to join back the cluster, by right should choose which node as donor ?

if choose node1 as donor, i sure it will use state transfer IST, cause the transaction still in node1 galera cache.

if i choose node3 as donor, will it perform IST or go for SST ? 

Is that galera cache in node1 will copy over and save 1 copy in node2 and node3 ?
