sporadic successfull mount of nfs with Stretch

[Stefan K <shadow_7@gmx.net>]

Hello,

we've some problems with Debian stretch which try to mount nfs4 shares at boot-time, sometimes it works and sometimes not. If its not mounting during start I can mount it after I login without problems.

A successfull (re)boot look like [1] and a (re)boot which doesn't mount the shares look like [2].

For me it looks like that it comes to a race condition and it try to mount it without a working networkstack. the /etc/fstab looks like:
srv-storage:/scratch              /scratch        nfs     defaults        0 2
srv-storage:/home         /data/home      nfs     defaults        0 2

I also try to use _netdev as mountoptions, but it didn't work.
Has anyone an idea how to solve this?

best regards
Stefan
