Temat: [DNG] NFS rookie mistake?
Here is the story:
I needed to do some server maintenance so I issued $init 1.
After the maintenance was done I issued $init 5.
Everything was fine except no nfs-server-kernel running.
No problem.
Issue $sudo /etc/init.d/nfs-kernel-server restart
System response:
Stopping NFS kernel daemon: mountd nfsd.
Unexporting directories for NFS kernel daemon....
Exporting directories for NFS kernel daemon....
Starting NFS kernel daemon: nfsd
Not starting: portmapper is not running ... (warning).
Problem to be investigated LATER.
Issue $ /etc/init.d/rpcbind restart
System response:
Stopping RPC port mapper daemon: rpcbind.
Starting RPC port mapper daemon: rpcbind.
No problem.
Try nfs server again.
$sudo /etc/init.d/nfs-kernel-server restart
System response:
Stopping NFS kernel daemon: mountd nfsd.
Unexporting directories for NFS kernel daemon....
Exporting directories for NFS kernel daemon....
Starting NFS kernel daemon: nfsd mountd.
no problem.
So, Now it is LATER.
So obviously when I went to runlevel 1, rpcbind was stopped and
didn't come back up when I went back to runlevel 5.
Investigate:
/etc$ sudo find . -name *nfs-kernel-server
./rc2.d/S04nfs-kernel-server
./rc0.d/K01nfs-kernel-server
./rc1.d/K01nfs-kernel-server
./default/nfs-kernel-server
./init.d/nfs-kernel-server
./rc3.d/S04nfs-kernel-server
./rc4.d/S04nfs-kernel-server
./rc6.d/K01nfs-kernel-server
./rc5.d/S04nfs-kernel-server
Observation:
nfs-kernel-server gets killed at 0,1,6
and gets started at runlevels 2-5
/etc$ sudo find . -name *rpcbind
./rc0.d/K06rpcbind
./rc1.d/K06rpcbind
./rcS.d/S17rpcbind
./default/rpcbind
./init.d/rpcbind
./rc6.d/K06rpcbind
./insserv.conf.d/rpcbind
Observation:
The only time rpcbind is brought up is at system start.
RUNLEVEL 1 kills it.
Conclusion:
So either rpcbind shouldn't be killed at runlevel 1 or it should be
started prior to nfs-kernel-server on runlevels 2-5.
OR .....
I have no clue about something here.

Ken
