Hi List, I must be going mad or something, but got a really odd problem with NFS mount and a DVD rom. Here is the situation, /dev/md7 58G 18G 37G 33% /data which is shared out by NFS, (/etc/exportfs) This has been working since I installed the OS, Centos 4.4 I have a DVD on that is device /dev/scd0, which I can mount anywhere I like, no problem. However, the problem comes when I try to mount it under /data/shared/Photos/Archive1. It mounts ok, and I can see the data on it form the server, but I cannot see this data over the network on any NFS client when mounting /data/shared. If I mount /devscd0 as /mnt and export that, I can mount the over the network fine. If I take another device, /dev/md4 and mount in same place, (/data/shared/Photos/Archive1) i cannot see those files over the network either. I do this kind of thing not quite everyday on Solaris and it just works.. I know I must be missing something, but i'll be b*gger** if I know what. No messages in any /var/log/* file. Any ideas would be most appreciated? Cheers AM

Looked, and applied... no change.. these are the relevant lines in the /etc/exports /data/shared/ 172.16.1.0/255.255.255.0(sync,rw,nohide) /data/shared/ 172.16.4.0/255.255.255.0(sync,rw,nohide) (need to export to different subnets, anything else doesn't work) Cheers AM> _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
