i posted this also to linux-nfs, maybe this is a more appropriate place
as it's clearly a "user" problem
i'm trying to mount a NFS 4 share with "sec=sys" from a NetApp FAS3250
on a CentOS KVM guest. this doesn't work, the mount doesn't complete and
mount command is:
/bin/mount -v -t nfs -s -o vers=4.1,sec=sys 10.110.96.90:/home /home/cir
what i'm seeing in tcpdump is:
08:36:48.875019 IP 10.110.96.112.2456702824 > 10.110.96.90.2049: 212
getattr fh 0,1/53

ok 96 getattr ERROR: Request couldn't be completed in time
status of nfs services:
this happens with a centos 6 _and_ a centos 7 client (both KVM guests).
NFS 3 mount of the share doesn't work either.
other kvm guests (centos 6) on the same physical host can mount the
share with no problem.
the netapp admin tells me there's "no problem" on his side.
iptables is disabled of course.
what could be the problem on my (client) side?
could this be a kvm problem?
kvm host is centos 6.
network mode is "bridge".
network driver is "virtio".
thx for any advice
