this could be due to many reasons. If your data is in a nfs mounted drive, restart nfs and it should fix the problem.

selinux: samba and nfs
I find “man samba_selinux” really well documented. All the common problems associate with samba selinux can be found there.
nfs and firewall issues
nfs can be setup easily using the GUI, ie
yum install system-config-nfs
The problem with nfs is that it uses certain random ports. If you have firewall enabled, you have problems. The trick is to fix the ports that nfs uses and simply enable those ports in the firewall. After checking up /etc/services, I chose a few ports that haven’t been used.
vim /etc/sysconfig/nfs
Comment off everything and and add these lines to it.
LOCKD_TCPPORT=30100 LOCKD_UDPPORT=30101 MOUNTD_PORT=30102 STATD_PORT=30103
then in the firewall
vim /etc/sysconfig/iptables
open the ports
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 111 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 111 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 2049 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 2049 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 30100 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 30101 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 30102:30103 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 30102:30103 -j ACCEPT
restart iptables and nfs and that should work.
* if you are configuring your firewall via the GUI, everytime you change the settings, it will wipe out your current settings. Remember to backup before doing it!!!
* Can check the nfs sharing status by using “showmount -e server”. If you cant get this command to work, something is wrong!
