Subject: Get "device is busy" when umounting  nfsv4 file
Date: Fri, 23 May 2014 10:14:29 +0800	[thread overview]
Message-ID: <537EAF05.2020900@gmail.com> (raw)

When using NFSv4 on Fedora 20 with latest kernel (3.15.0-rc6+), 
I can't umount the mountpoint after only an 'ls' operation.

[root@localhost ~]# cat /etc/exports
/nfstest        *(rw,no_root_squash,no_subtree_check,insecure)
[root@localhost ~]# mount -t nfs 127.0.0.1:/ /mnt/
[root@localhost ~]# ls /mnt/
nfstest
[root@localhost ~]# umount /mnt/
umount.nfs4: /mnt: device is busy
