#209006 — sporadic successfull mount of nfs with Stretch

Subjectsporadic successfull mount of nfs with Stretch
Message-ID<y0Azn-4nV-1@gated-at.bofh.it>
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

Wonder what would happen if you used the IP address instead of the 
srv-storage?

Following on Keith's suggestion: If replacing the hostname with the IP
address doesn't help, look at the error rates on the network interfaces.
Especially look for speed mismatches in the Ethernet config at the 2 ends.

I use defaults,retry=5,_netdev - never had an issue with this. I must admin
I still use init and not systemd. But when testing with systemd I do not
recall having problem. I think I switched back to init after the mounts
were setup. If using systemd, check your dependencies.

I solved this issue by installing the latest backport kernel

So my question would be, did logs indicate that Ethernet autonegotiation
failed with the new-old-bad drivers, but succeed with the backport level?
