Public bug reported:
Xubuntu 14.04.01 LTS, x86-64.
Linux akhenaten 3.13.0-39-generic #66-Ubuntu SMP Tue Oct 28 13:30:27 UTC 2014
x86_64 x86_64 x86_64 GNU/Linux
On this machine, "/var" volume is formatted with XFS. XFS is formatted
during the installation of Xubuntu.
/etc/exports has an entry to export "/var/www":
/var/www 192.168.10.0/24(rw,sync,no_root_squash,no_subtree_check,insecure)
The Linux NFS client can mount the NFS export but trying to access it returns
an error. (And incorrect message of it.)
mount akhenaten:/var/www /mnt/www
ls /mnt/www
This does not work. I have tried a few variations, and this is what I know.
(1) If you export the root of XFS volume ("/var" this case), it works.
(2) If you create a direcotry such as /exports/www, use "mount -o bind" to bind
/var/www with /exports/www and export it, the client times out.
(3) If the file system is EXT4, the NFS export works. (I copied the XFS /var to
another disk with EXT4 formatted volume, changed /etc/fstab and rebooted,
without any other changes.)
