Can anyone help me out of a very stupid situation which is totally my fault (well almost).
I added another NFS shared via the GUI and for some reason it failed, not totally sure why as NFS has been running
fine for ages (over 70 days uptime!) the error message was complaining about duplicate entries in /etc/exports
So thinking that I could fix the problem. Checked /etc/exports and notice duplicate entries so removed those and then restarted the NFS-Kernel-Server and got the following error
Code
sudo service nfs-kernel-server start
Exporting directories for NFS kernel daemon....
Starting NFS kernel daemon: nfsdrpc.nfsd: Setting version failed: errno 16 (Device or resource busy)
nfsdrpc.nfsd: Setting version failed: errno 16 (Device or resource busy)rpc.nfsd: writing fd to kernel failed: errno 5 (Input/output error)
rpc.nfsd: unable to set any sockets for nfsdSo tried clearing the exports file, so it looks like this
Code
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
#Then checked hosts.allow
Code
cat /etc/hosts.allow
# /etc/hosts.allow: list of hosts that are allowed to access the system.
# See the manual pages hosts_access(5) and hosts_options(5).
#
# Example: ALL: LOCAL @some_netgroup
# ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
#
192.168.1.*
and hosts.deny
Code
cat /etc/hosts.deny
# /etc/hosts.deny: list of hosts that are _not_ allowed to access the system.
# See the manual pages hosts_access(5) and hosts_options(5).
#
# Example: ALL: some.host.name, .some.domain
# ALL EXCEPT in.fingerd: other.host.name, .other.domain
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
#
# The PARANOID wildcard matches any host whose name does not match its
# address.
#
# You may wish to enable this to ensure any programs that don't
# validate looked up hostnames still leave understandable logs. In past
# versions of Debian this has been the default.
# ALL: PARANOIDSo all good there (i think)
checked port map and no complaints

iF nfs-kernel-server 1:1.2.2-4squeeze2 support for NFS kernel server
rc portmap 6.0.0-2 RPC port mapperSo I save the very best bit and the most stupid, stupidly, stupidly, tried to remove nfs kernel server but rather than remove I chose the try purge and DIDN'T read the message properly :oops: and have accidental removed Open Media Vault.
The server is working and I can still access the data but fear that I might of really broke something. The server has 4 x 500g drives in a RAID 5 with an LVM on top.
So not sure what to do now as I can't reinstall Open Media Vault as it depends on NFS-Kernel-Server and that fails...
