Hi,
if I understand this correctly, with the "keepalive-only" option only
one ganesha instance is supposed to be deployed:
If a user additionally supplies --ingress-mode keepalive-only a
partial ingress service will be deployed that still provides a virtual
IP, but has nfs directly binding to that virtual IP and leaves out any
sort of load balancing or traffic redirection. This setup will
restrict users to deploying only 1 nfs daemon as multiple cannot bind
to the same port on the virtual IP.
Maybe that's why it disappeared as you have 3 hosts in the placement
parameter? Is the ingress service still present in 'ceph orch ls'?
As I read the documentation[1] the "count: 1" handles that so what I
have is a placement pool from which only one is selected for deployment?
The absence of the ingress service is puzzling me, as it worked just
fine prior to the upgrade and the upgrade shouldn't have touched the
service spec in any way?

Zitat von Torkil Svensgaard <torkil@xxxxxxxx>:
Hi
Last week we created an NFS service like this:
"
ceph nfs cluster create jumbo "ceph-flash1,ceph-flash2,ceph-flash3"
--ingress --virtual_ip 172.21.15.74/22 --ingress-mode keepalive-only
"
Worked like a charm. Yesterday we upgraded from 17.2.7 to 18.20.0 and
the NFS virtual IP seems to have gone missing in the process:
"
# ceph nfs cluster info jumbo
{
"jumbo": {
"backend": [
{
"hostname": "ceph-flash1",
"ip": "172.21.15.148",
"port": 2049
}
],
"virtual_ip": null
}
}
"
Service spec:
"
service_type: nfs
service_id: jumbo
service_name: nfs.jumbo
placement:
count: 1
hosts:
- ceph-flash1
- ceph-flash2
- ceph-flash3
spec:
port: 2049
virtual_ip: 172.21.15.74
"
I've tried restarting the nfs.jumbo service which didn't help.
Suggestions?
Mvh.
