Hi Rick, thanks for answering, but it seems there's a slight mis-understand=
ing.
* I have 3 NFS exports, mount version on client confirmed with "nfsstat -m":
V2: /data/amd64, mounts to root as ro
V4: /usr/local, mounts to same as ro
V4: /home, mounts to same as rw
* Root is being mounted as V2, not a problem for me. However, when I "ls -l=
a" /home or /usr/local (the V4 mounts), I see file ownership problem (numbe=
rs instead of actual user name). This is true for folders owned ANY user (r=
oot, me, etc):
drwxr-xr-x 106 32767 32767 date-time folder-name (always the same nu=
mber 32767)
* I turned on some debugging with "nfsuserd -verbose" and I can see:
added uid=3D0 name=3Droot \ added gid=3D0 name=3Droot
added uid=3D1001 name=3Dme \ added gid=3D1001 name=3Dme
added uid=3D350 name=3D_sabnzbd \ added gid=3D350 name=3D_sabnzbd
* Most Likely reason: The NFS-V2 export (client root /data/amd64 folder) is=
at the same time a Jail. This probably causes "some process number in the =
jail" not matching up with process number on Host, thus the failure to assi=
gn proper name to file ownership. My /etc/jail.conf:
pxe { name =3D pxe;
path =3D /data/amd64;
ip4.addr =3D 192.168.2.1; #subnet as /32 breaks tftp
host.hostname =3D pxe.me;
devfs_ruleset =3D 12;
allow.raw_sockets;
mount.devfs;
mount.fstab =3D /etc/fstab.pxe; }
* I start the diskless client system with below script. Any additional pxe =
service (dhcp, tftp, etc) is defined in /data/amd64/etc/rc.conf.
jail -c pxe
rpcbind -s -h 192.168.2.1
mountd -rnl -h 192.168.2.1
nfsd -ut -n 4 -h 192.168.2.1
nfsuserd -verbose
* Starting dbus/hald on client while nfsuserd is running results in:
a) added gid=3D556 name=3Dmessagebus \ added gid=3D562 name=3Dpolkit
b) No message about "nfs_getpages: error 13"
* If I don't run nfsuserd, or if I use NFS V2/3 for the /usr/local export:
a) File permissions on the non-root exports get displayed by name.
b) I see the "nfs_getpages: error 13" message.
* I did not try the "-maproot=3Droot" solution, because it does not address=
the problem of regular users (ie me) having incorrect file ownership under=
/home/me.
* File ownership under /var/run is correct because it's not NFS (it's MD)
I hope I was better able to explain the issue this time.
Regards.
