On Docker Swarm Manager host nodes status shown as ready and active
$ docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS ENGINE VERSION
mmbxdeerfwperedsbj6l8zr71f * svr-1 Ready Active Leader 20.10.7
kzc7jf7irsereed3kurcwqjb2j svr-2 Ready Active 20.10.7
ew0edluvz39aregd87ld0wnv2e svr-3 Ready Active 18.06.1-ce
On svr-3 host everything working fine. I have tried below services to solve on svr-2, Unfortunately couldn't help me.
sudo systemctl daemon-reload
sudo systemctl enable docker
sudo systemctl start docker
On Leader host mount part as follows.
docker inspect m64
"Mounts": [
{
"Type": "bind",
"Source": "/data/m64/",
"Target": "/root/.m64/"
},
I'm new to docker swarm i really appreciate if someone help me to solve this issue.
Issue was with svr-3 server volume /data/m64/, sym link was missing. have created symbolic link and problem solved.
