[SOLVED] nfs: copying file

jcky · 09-08-2009, 04:55 AM

I used suse v10 sp2 linux. I encountered a strange problem and need your kind help.
mount -o rw,soft,timeo=10 192.168.56.220(server_ip):/suse2 /nfs(local mount point)
When I want to cp a big file from server to local and simultaneously stop the nfsserver service of the server. The cp command is just hanging(ctrl+c no use!).And after more than 10 seconds, the cp command was still hanging. I used soft mount, but why it is still hanging ? It was said in the book that the system should give some wrong information like input/output error and then stopped working.
Please help me!

If its a real big file then its normal to stop responding for a while. It would take some minutes or so.

So wait for some time, after the copying is complete it will be back to prompt

Sorry, you may misunderstand my meaning.
Normally, the system should give some wrong information, because the nfsserver service was stopped and I used soft mount.
Thanks for your help!

If you want cp to continue the operation while nfs server restarts, this is a bit problem. Instead you can use scp to copy from server.

I thought you needed help because your finger was stuck on the ! key.

What I want to test is that rthe soft mount test could be ok. But failed.
Thanks for all.
Anyone can explain the problem?
Thanks!

Very strange!
I used scp instead of cp. Also failed.(soft mount)
And ps aux checked.
It showed S status on scp command. But when I used ctrl+c, it is still hanging.(i.e no use)
Who can help me!!!!!

what does hanging means? your whole system or just the console( I suppose just the console) ?

How big is the file and how much time did you wait ?

Check this page http://www.linuxtopia.org/online_boo...g-options.html . I reckon you need the 'intr' option as well.

Hi all,
Because the soft mount based on RPC. So if I closed the nfs server, the soft mount would not take effect. But if I stopped the network service or shutdowned the server that meant the rpc port was closed. The soft mount took effect.Last time, I misunderstod the meaning of soft mount so that I got confused. That is the problem.
