Seems to be very hard to type a few commands ?
Anyway, I can confirm something is wrong on openpli-7
# cat /etc/exports
/media/hdd *(rw,no_root_squash,sync)
# exportfs
/media/hdd <world>
# ps | grep nfs
508 root 0 SW< [nfsiod]
1466 root 0 SW [nfsd]
1467 root 0 SW [nfsd]
1468 root 0 SW [nfsd]
..
# showmount -e localhost
clnt_create: RPC: Program not registered
# /etc/init.d/nfsserver stop
stopping mountd: done
# /etc/init.d/nfsserver start
starting 8 nfsd kernel threads: done
starting mountd: done
exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/media/hdd".
Assuming default behaviour ('no_subtree_check').
NOTE: this default has changed since nfs-utils version 1.0.x
# /etc/init.d/nfsserver status
/usr/sbin/rpc.mountd (pid 4182) is running...
nfsd (pid 4180 4179 4178 4177 4176 4175 4174 4173) is running...
# ls -l /etc/rc3.d/S20nfsserver
lrwxrwxrwx 1 root root 19 Feb 14 21:45 /etc/rc3.d/S20nfsserver -> ../init.d/nfsserver
# showmount -e localhost
Export list for localhost:
/media/hdd *
And I can now mount /media/hdd from another PC.
I.e. (re-)starting nfsserver seems to have "fixed" it. Note the box was freshly started from deep-standby.
