I’m running a small 3 node cluster, during an AHV upgrade to the latest version one of the servers failed to reboot so AOS started to rebuild trying to restore HA. After several hours rebuilding failed, looking at the logs I saw the message: “not enough space available”.
If I’m not mistaken a 3 node cluster can tolerate only one node down, but lets say the two running nodes had enough space, is it possible to restore HA? It basically means that after some time rebuilding, if one of the 2 remaining nodes fails, cluster is still up in a single node mode.
Just curious because it looked like AOS tried to rebuild HA despide only 2 nodes were up
