I was trying to check longhorn HA by doing one experiment on my cluster. Here the details what I am trying to do:
I am initiating one workload and in the volume section I am attaching longhorn PVC as a storage volume as 3 replicas, but whenever I turned off the instance(with IP 10.x.x.A) on which that workload Pod is running it, Either it won’t able to switch to different node (because it is failing to detach and attach PVC storage) though it has option on running other nodes in the cluster i.e. 10.x.x.B and 10.x.x.C. or
if I turned on the instance(with IP 10.x.x.A) that Pod is not able to run successfully until I manually redeploy it, though it is trying to switch from A to B but it is failing in attaching the PVC storage.
It look like something this:
Above scenario happens most of the time and sometimes it happen to do the things correctly. Any help or information is highly appreciated.
Longhorn Version: 0.5.0
Rancher Version : 2.2.4
Thanks and Regards
