Comment 6 Xingxing Xia 2022-04-20 04:38:27 UTC
Increasing Severity because several QEs observed and reproduced this 4.11-cluster-dead issue after about 10 ~ 11 hours since fresh clusters were installed, see #forum-qe channel https://coreos.slack.com/archives/CH76YSYSC/p1650427961844569?thread_ts=1650379744.641499&cid=CH76YSYSC after I raised it for wider discussion and input.

Comment 20 Mike Fiedler 2022-04-20 13:29:41 UTC
Marking this as a TestBlocker since it prevents running a cluster > 12 hours

Comment 37 ge liu 2022-04-24 02:26:43 UTC
we have prepared cluster and waiting for its status after 12H
