Often NFS in container does not work because of misconfiguration. This article contains known reasons of such problems as well as solutions for those.

Mount hangs[edit]

Symptoms[edit]

mount command hangs or takes a very long time to complete:

# mount <ip address>:/pub /data
(...hangs here...)

Reasons[edit]

  • Lockd is not running on the NFS server
  • Portmap (older) or rpcbind (newer) is not running on the NFS client
  • Networking is broken (e.g. scripts brought up default route but not IP address yet)

Solution[edit]

Two options are possible:

  • run lockd on the server
  • mount with nolock option

Links[edit]
