Issue with Convoy-NFS causing docker problems

Good day all. We woke up today with docker down on one of our hosts and we can’t seem to get it started again.

We keep seeing convoy-nfs errors as shown below. We are not even using convoy at the moment, although we tried it out on this server months ago.

Any ideas on how this can be fixed?

Thanks in advance!

I had once problem too with convoy and i had to remove some old files in:

/var/lib/rancher/convoy

Maybe…but better make a backup before.
