Solutionthis is a clasic problem that you have when you issue a hardcopy of nfs .
when the nfs server goes down the mount point hang , and some command will be hang , the most common is bdf .
to solve this issue you can do a few things :
1. start the nfs server and the problem will disapper .
2. reboot the server ! yes , sorry
if you want to avoid this kind of problem do a soft mount of nfs that will not cause you this problem .
or you can you autofs or automounter .

Re: bdf hangs on other mahines when nfs server was shutdown
Its a feature.
If machinea has an nfs mount on machineb and machineb is down, of course bdf will hang.
If the nfs mount is:
/nfsmount
umount /nfsmount
Then bdf
The problem may go away.
Because you have a stale nfs mount, you may need to stop/start /sbin/init.d/nfs.client before the bdf hangs.
Your system is acting normally. Bring up server2 and all will work well.

Re: bdf hangs on other mahines when nfs server was shutdown
NFS is treated as a real disk, so yanking that disk out of service is just the same as yanking out a mounted hard disk. Now automounter or autofs can help the situation but NFS should be used with caution on production machines.

Re: bdf hangs on other mahines when nfs server was shutdown
Stop the NFS cli├Г┬лnt and start it when the NFS server is back, this will solve your bdf hang.
