I have a 300 gig hard drive that is mounted to /myth/video to hold my dvd collections. Everything is seen fine and the movies are seen when playing on the backend yet I cannot get the separate frontend to see the movie files. I followed the KMwiki guide and made a directory that was mounted to the backends /myth/ folder. When I browse through the folder the video directory is seen as if the separate hard drive wasn't there. Do I need to do something extra to get the NFS to see the hard drive mounted there?

You need another mount for the other file system. Make sure /myth/video is in your /etc/exports and then add another NFS mount like the one for /myth in the /etc/fstab file on the FE box.

Ok. Thanks for the info tjc. Just to make sure I just have to edit these two files:

On the backend /etc/exports file there is a couple commented out things and then

so I just add


and on the frontend /etc/fstab file i add


I have to reboot both machines dont I?

You don't have to reboot, you just have to restart the nfs services on the backend after you manually mount:



Let us know if this works. I remember trying to do exactly what you are doing and having trouble. This is how I ended up setting it up:

backend:


frontend:

No, that's like mounting a normal hard drive, you're trying to mount a share which is slightly different syntax. Instead of "partition mount-point", it's "server-share mount-point"

Thanks for your help guys. I took all your suggestions and got it working. KM community FTW lol

Ok Ive found a new issue. Everything works fine until I have to reboot the frontend. Then I lose the mounts. Here is the contents of my /etc/fstab file on the frontend:



There is also more below but it looks to just be floppy, cdrom, sb etc.
I can go into the command line and mount them no problems but did I type somethin incorrectly in the fstab so they are not mounted on boot?

Should be:

Also, make sure that your backend has a static IP, not DHCP...

Technically DHCP shouldn't be a problem iff you configure the DHCP server to always give the same IP address to your mythbox. This is a pretty standard feature on home routers.

Actually...

Actually... I think that should be:

Appreciate the suggestion, tjc, but that doesn't work for me

I'm sure it's just my naiveté, but if I try it this way it doesn't work. I have a similar setup. I purchased a 500GB sata and I didn't want to roll it up into my LVM, so I decided to just put my videos on it. I had to mount the drive outside of the /myth partition and create a symbolic link to it. If I tried to mount the drive inside the /myth partition I could access it on the backend but not on a separate frontend.

Again, maybe it can be done, but I couldn't figure it out...

Thanks TJC. Worked like a charm. Just noticed Kirk pretty much said the same thing a couple posts ago but in my mind its just going "well its an ext3 formatted drive so I must have to put ext3 in there " hehe

KM do you have NFS working on the backend?

I think you missed a step somewhere then. One the BE box where the drive lives you mount it like this in /etc/fstab:

In your /etc/exports on the BE box you export both directories:

On the remote machine you then can use something like this in your /etc/fstab there:

The nohide and crossmnt options for exports also do similar things with only one export and remote mount but can have some odd issues.

Reading man exports and man nfs is highly recommended. I did my first NFS setup something like 18 years ago and still check the associated man pages whenever I'm messing with this stuff.

So the "subtree_check" is what I was missing. Like I said, you could probably do it, I just didn't know how

Thanks for the tip. I'll probably leave my system as-is for now as it is working, but I'll probably change this in the next upgrade.

tjc,
I'm curious, in my reading of the exports manpage, it seemed no_subtree_check was more appropriate, but I find the manpage a bit vague. It says no_subtree_check "has mild security security implications, but can improve reliability in some circumstances" but it doesn't say what implications, or what circumstances improve reliability. Anyway it seems to imply that if you are exporting the entire filesystem then subtree checks are not needed, it then seems to contradict saying in examples that /homes should have checks disabled and /usr and /var should be enabled indicitating that the frequency of file renames is the deciding factor.
Anyway, and I apologize if I'm pulling this off topic, but what does subtree checking mean to you?
