Reason:
For the people that do not want to setup NFS server on windows but want to use windows share to store fog images.
Windows share that use CIFS/SMB mount will only work with user space NFS server such as unfsd3 or NFS-Ganesha
The regular kernel mode nfs_kernel_server does not compiled to support NFS re-export.
Assume you have a windows server with a share folder call fogshare and the share user is fog with the password fog. The FOG sever is on Ubuntu server.
sudo -i
#install CIFS support
apt-get install cifs-utils
#Backup images folder so you can copy .mntcheck file later
mv /images /images.old
mkdir images
chmod -R 777
#edit /etc/fstab to add the following line so windows share folder will mount to /images
//windows server IP or name/fogshare /images cifs username=fog, password=fog,noserverinfo,iocharset=utf8,file_mode=0777,dir_mode=0777,sec=ntlmssp 0 0
#backup /etc/exports
cp exports exports_nfs_kernal_server
#remove nfs_kernal_server
apt-get remove nfs-kernal-server
#add the unfsd3 server source to /etc/apt/sources.list
#add archive lucid apt source for unfsd3
#Lucid
deb http://old-releases.ubuntu.com/ubuntu/ lucid main restricted universe
deb-src http://old-releases.ubuntu.com/ubuntu/ lucid main restricted universe
#install unfs3
apt-get update
apt-get install unfs3
#unfs3 does not like a * in the /etc/exports
replace the * with internal network x.x.x.x/24
/images x.x.x.x/24(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images/dev x.x.x.x/24(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)
#backup exports for future use
cp /etc/exports /etc/exports_ufs3
#copy /image.old files to the new /images
#restart unfs3
/etc/init.d/unfs3 restart
This works on Ubuntu 14.04 and should work with other version as well.
