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?
Try adding nohide as an option to /etc/exports. See exports(5) for more information about nohide and exporting filesystems with mount points.
Most interesting.
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
