* I can't get the NFS server to run V4 only. I have:
sysctl vfs.nfsd.server_min_nfsvers=4
I start all NFS-related services manually (from script)
#!/bin/sh
rpcbind -s -h 192.168.2.1
mountd -rnl -h 192.168.2.1
nfsd -ut -n 4 -h 192.168.2.1
nfsuserd
/etc/exports has:
V4: / -network 192.168.2.0/26
/data/amd64 /data/amd64/boot/s386 -ro -network 192.168.2.0/26
/usr/local -ro -maproot=0 -network 192.168.2.0/26
/home -network 192.168.2.0/26
Running "nfsstat -m" from a PXE client gives me:
192.168.2.1:/data/amd64 on /
nfsv2,tcp,resvport,hard,cto,lockd,sec=sys,acdirmin=3,acdirmax=60,acregmin=5,acregmax=60,nametimeo=60,negnametimeo=60,rsize=8192,wsize=8192,readdirsize=8192,readahead=1,wcommitsize=1997092,timeout=120,retrans=2
192.168.2.1:/home on /home
nfsv3,tcp,resvport,hard,intr,cto,lockd,sec=sys,acdirmin=3,acdirmax=60,acregmin=5,acregmax=60,nametimeo=60,negnametimeo=60,rsize=65536,wsize=65536,readdirsize=65536,readahead=1,wcommitsize=1997092,timeout=120,retrans=2
192.168.2.1:/usr/local on /usr/local
nfsv3,tcp,resvport,hard,cto,lockd,sec=sys,acdirmin=3,acdirmax=60,acregmin=5,acregmax=60,nametimeo=60,negnametimeo=60,rsize=65536,wsize=65536,readdirsize=65536,readahead=1,wcommitsize=1997092,timeout=120,retrans=2
The PXE-booted kernel is compiled with: nfscommon, nfssvc, nfs, nfscl,
nfslock
On server side, in addition to the above, these are loaded as modules:
acl_nfs4.ko, nfsd.ko, nfslockd.ko
PXE client's /etc/rc.conf the only NFS-related entry is:
nfs_client_enable="YES"
PXE client's /etc/fstab is:
92.168.2.1:/data/amd64 / nfs ro 0 0
192.168.2.1:/usr/local /usr/local nfs ro 0 0
192.168.2.1:/home /home nfs rw,hard,intr 0 0
* Considering V2/V3 for NFS is getting dropped from code base, PXE clients
used to need max V3 as root and could not mount_root with V4. Has this
changed? If so, what services do the clients need to get V4 on root working
(RO, no RW)?
* There was a simple command to show from server-side what version of NFS
the exports were running, but I seem to have lost that. Any clues?
* Have any of these services become capable of running from inside a jail
environment? {rpcbind mountd nfsd nfsuserd} - it does not seem so, but just
checking.
Thanks and Regards.
