[K12OSN] LTSP - NFS/CIFS

[Daniel Bramkamp]

Hi,

I am currently running a LTSP setup for 60 users. The /home directory 
and data is provided to the terminalserver via NFS. However, NFS is 
giving me headaches. Sometimes access to all files and directories on 
the NFS server is being denied. I cannot figure out why this happens. 
The problem arises very infrequently. I reinstalled the whole file- and 
terminalserver. The software on the servers is up to date now. The 
problem happened with the old installation, which was 2 years old, and 
it still exists in the new installation. The problem goes away after a 
few minutes and everything works smoothly again. The fileserver is also 
running Samba. User accounts are stored centrally in a LDAP database. 
UIDs/GIDs match on both servers. Users are in no more than 13 groups 
max.

1. Has anyone experienced similar issues with NFS?

2. Is it possible to use Samba/CIFS instead of NFS in a setup like this 
? Can anyone comment on possiblity, stability, etc. ? One of the nice 
things about using NFS is that I only need to mount the share once at 
system startup. Can something like that be archived when using CIFS and 
ACLs maybe ? Help would be very much appreciated.
Thanks in advance.
