Hey guys.. I had a working Debian sid (server & client) nfs setup
until recent packages and kernel upgrades. After rebooting the boxes,
the client no longer sees any dirs or files in the shares. I booted
back into the previous kernel on both boxes but that didn't help. I
don't have a list of packages that were upgraded so I thought maybe
I'd just try to rebuild things from scratch but after tons of reading
and trying various things, its gotten me absolutely nowhere. I'm
hoping to find help getting even just a single share to work correctly
at this point. Based on everything I've read, the following should
work but doesn't. I'm not sure if the howtos and guides I followed
are outdated now, or something from the package upgrade is causing the
problem, or what.. Can someone knowledgable & experienced with nfs
please tell me if I've done something wrong in the steps below?
Any help is *greatly* appreciated!

I have a harddrive in my server that contains a dir I want to share
called "media". "media", all subdirs, and all files are owned by UID
1000/GUID 1000. All dirs are chmod 0755. "media" looks something like
this:
media/homevideos/vacation2017/*.mkv
media/music/*.mp3
media/musicvideos/*.mp4
The mountpoint on my client is also owned by UID 1000/GUID 1000, chmod
0755. Server and client are running Debian sid with nfs v3 & v4
enabled in the kernel. I don't use/want auto-mounting. Both boxes have
identical hosts.allow and hosts.deny files:
--------------------
hosts.allow:
ALL: 192.168.1.*
hosts.deny:
ALL: *.*.*.*
ALL: PARANOID
--------------------
on the server I do:
$ sudo mkdir -p /testhd/hd0
$ sudo mkdir -p /testnfs/sharehd0
$ sudo chown -R 1000.1000 /testhd
$ sudo chown -R 1000.1000 /testnfs
$ sudo mount /dev/sde1 /testhd/hd0
$ sudo mount --bind /testhd/hd0/media /testnfs/sharehd0
$ mount |grep "/test"
/dev/sde1 on /testhd/hd0 type ext4 (rw,relatime,data=ordered)
/dev/sde1 on /testnfs/sharehd0 type ext4 (rw,relatime,data=ordered)
At this point I can `ls -la` and see that both /testhd/hd0/media/* and
/testnfs/sharehd0/* have the same contents and still everything owned
by UID 1000/GUID 1000. I then create /etc/export and start the server:
$ echo "/testnfs
*(ro,fsid=0,no_subtree_check,insecure,all_squash,anonuid=1000,anongid=1000)"
|sudo tee /etc/exports
$ echo "/testnfs/sharehd0
192.168.1.0/24(ro,no_subtree_check,insecure,all_squash,anonuid=1000,anongid=1000)"
|sudo tee -a /etc/exports
$ sudo /etc/init.d/nfs-kernel-server start
So far so good?:
$ sudo rpcinfo -t 192.168.1.11 nfs
program 100003 version 3 ready and waiting
program 100003 version 4 ready and waiting
$ sudo showmount -e 192.168.1.11
Export list for 192.168.1.11:

Ok so now for the client-side:
$ sudo mkdir -p /testshare/share0
$ sudo chown -R 1000.1000 /testshare/share0
$ sudo showmount -e 192.168.1.11
Export list for 192.168.1.11:

$ sudo mount 192.168.1.11:/testnfs/sharehd0 /testshare/share0
$ mount |grep nfs
