I considered that, but I would expect more nodes to be lost.

Okay, I set up active/ backup bonding and will watch for any change.
This is the network side:
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 output errors, 0 collisions, 0 interface resets
This is the server side:

I need to run some fiber, but for now two nodes are plugged into one switch and the other two nodes into a separate switch that are on the same subnet. I'll work on cross connecting the bonded interfaces to different switches.

The first thing I would do is get a second NIC and configure
active-passive bonding. network issues are too common to ignore in HA
setups. Ideally, I would span the links across separate stacked switches.
As for debugging the issue, I can only recommend to look closely at the
system and switch logs for clues.

No
bonding, single link. What else can I look at? I manage the network
too. I don¹t see any link down notifications, don¹t see any errors on
the ports.

I turned corosync output to debug. How can I go about
troubleshooting if it really is a network issue or something else?
Jun 09 13:06:59 corosync [QUORUM] Members[4]: 1 2 3 4 Jun 11
14:10:17 corosync [TOTEM ] A processor failed, forming new
configuration.
Jun 11 14:10:29 corosync [QUORUM] Members[3]: 1 2 3 Jun 11 14:10:29
corosync [TOTEM ] A processor joined or left the membership and a
new membership was formed.
Jun 11 14:10:29 corosync [CPG ] chosen downlist: sender r(0)
ip(10.70.100.101) ; members(old:4 left:1)
This is, to me, *strongly* indicative of a network issue. It's not
likely switch-wide as only one member was lost, but I would
certainly put my money on a network problem somewhere, some how.
Do you use bonding?
