A good and a bad news

[Vincent ROQUETA]

Hello all,

Two news. 
First the bad : 
The umount problem I have seen on NFSv4 exists also on v3

The good one :
If I do a sync on v3, the problem disappear - Well, consider that is a read 
only test, closing the file it use.


mount -t nfs 129.183.140.144:/Backup/ /mnt/nfs/ ; read_s /mnt/nfs/ro 
20000000 ; umount /mnt/nfs
-> Return : /mnt/nfs: device is busy

mount -t nfs 129.183.140.144:/Backup/ /mnt/nfs/ ; read_s /mnt/nfs/ro 
20000000 ; sync ; umount /mnt/nfs
-> correct umount 

I join the read_s test program. (Read with an initial seek )

Have a nice day ...
Vincent
