    Subject[QUESTION] NFS and new kernels.
    Date
    Hello, list,

    I use the NFS couple of years, so i think, i know what am i doing.
    I have 7 servers, that boots from NFS, using nfsroot.
    Now i plan to replace the NFS server, to completely newer system, and i get
    seriously strange messages.
    The general problem is i cannot mount any NFS shares, at all, after i
    upgrade the kernel the FC4-based kernel(2.6.11) to 2.6.16-rcX.
    I have spend some days to read mans, faqs, howtos, mailing list, but did not
    find any interesting.
    This tells me: i am the stupid. :-)

    The general problem, is this:

    (client)[root@st-0001 root]# mount: 192.168.0.2://mountpoint failed, reason
    given by server: Permission denied
    (server)[root@NetCenter log]# mount: localhost://mountpoint failed, reason
    given by server: Permission denied
    (client)[root@st-0001 root]# showmount -e 192.168.0.2
    /mnt/EXT 192.168.2.*
    /mnt/EXT/NFS/ROOT (everyone)
    /mountpoint st-0001
    etc...

    [root@st-0001 root]# rpcinfo -p 192.168.0.2
    program vers proto port
    100000 2 tcp 111 portmapper
    100000 2 udp 111 portmapper

    100005 3 tcp 1013 mountd


    (server "NetCenter")
    Feb 4 03:42:47 NetCenter rpc.mountd: mount request from unknown host
    127.0.0.1 for /mountpoint (/mountpoint)
    Feb 4 02:09:03 NetCenter rpc.mountd: authenticated mount request from
    192.168.2.50:728 for /mountpoint (/mountpoint)
    Feb 10 19:51:09 NetCenter mountd[26698]: authenticated mount request from
    st-0001:894 for /mountpoint (/mountpoint)
    ...

    [root@NetCenter log]# cat /proc/fs/nfs/exports:
    # Version 1.1
    # Path Client(Flags) # IPs
    /mountpoint st-0001(rw,no_root_squash,async,wdelay)

    The additional problem is, i cannot add, to this file all line in the
    /etc/exports.
    Only the named hosts.
    The exportfs -ra did not add, the * host.

    Before i upgrade the nfs-utils-1.0.8-rc2, the old exportfs did not add
    anything!

    The firewall, is off, on both systems.
    The /etc/hosts.allow and deny are both empty.

    What have i missing?

    Thanks,
    Janos
