What was the last change?
This can have multiple root issues, mostly Network.

 

[pille99]

the change i try to do was to change from sdn vxlan to evpn.
i changed the physically NIC as a vLan but it wasnt proper working. than i did the previous update. and since the ceph osd cant be seen again.

in the syslogs are shown

i have no idea from where the timeout is coming from. all ips are pingable

Do you use Jumbo Frames?
You can check with large Ping Packets.

ping to all and from all interfaces are now with the result in top. this config was running the last half year. why it doesnt work anymore ?
i changed to standard value (removed the value) and try again
the ping with
root@hvirt01:~# ping -M do -s 8972 10.10.12.11
PING 10.10.12.11 (10.10.12.11) 8972(9000) bytes of data.
8980 bytes from 10.10.12.11: icmp_seq=1 ttl=64 time=1.56 ms
8980 bytes from 10.10.12.11: icmp_seq=2 ttl=64 time=0.995 ms
is working. strange

fugg me - with 8972 mtu its working again.

i made to much changes at the time like create sdn, made the latest updates, and some changes on the network (just not the mtu value - because it was working). it must be of the new updates. maybe somebody else can confirm that
