So, I did look at the 20 first ailure, removed all not related to
rebal-all-nodes-migrate.t and seen all were run on builder203, who was
freshly reinstalled. As Deepshika noticed today, this one had a issue
with ipv6, the 2nd issue we were tracking.
Summary, rpcbind.socket systemd unit listen on ipv6 despites ipv6 being
disabled, and the fix is to reload systemd. We have so far no idea on
why it happen, but suspect this might be related to the network issue
we did identify, as that happen only after a reboot, that happen only
if a build is cancelled/crashed/aborted.
I apply the workaround on builder203, so if the culprit is that
specific issue, guess that's fixed.
I started a test to see how it go:
Sysadmin, Community Infrastructure and Platform, OSAS
