Thanks also for your response, I have tried you suggestion of: /home/user/media/ 192.168.2.0/24(rw,insecure,crossmnt,no_root_check,no_subtree_check) but got an error that 'no_root_check' was unknown, so i suppose just a type and meant was: /home/user/media/ 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check) but still it does not work, not only on ubuntu but also not on xbmc (openelec/rpi) ----- Original Message ----- From: J.

I have a server on the network with 20 different harddisks on this system that contain all my media. I have directory "/home/user/media" on my server into which i "mount --bind" all the media i want to be accessible on xbmc (on the pi) or on other computers on the local network.

After installing NFS I tried simple exports (one folder without any sub directories that have no 'mount --bind' in them) and accessing them works fine. So now I thought to export the '/home/user/media' directory but using the samba setup as described from above does not work. Ideally, I would like to have to nfs mount only '/home/user/media' and have all the 'mount --bind' folders accessible on the server also accessible on all clients. > Rather then using the xbmc/pi mentioned above I use my laptop with ubuntu to test the export mounts as a client. In samba it was enough to share the parent folder, in this case '/home/user/media' and everything below that share would be visible but as i understand this is not the case in nfs, I need to specify each sub directory that is 'mount --bind' (from a different file system) in the export. No, it should actually be sufficient just to export the parent. Also, we don't recommend fsid=0 any longer. Also, "async" should be avoided. So just: /home/user/media/ 192.168.2.0/24(rw,insecure,crossmnt,no_root_check,no_subtree_check) and you mount that with "mount myserver:/home/user/media /mymountpoint". (Note the "crossmnt", which tells the server to export all the children automatically.) If that doesn't work you've probably found a bug. I'd recommend reporting that to Ubuntu, and/or here if you can reproduce with recent kernel and nfs-utils. --b. > > my export file: > /home/user/media/ 192.168.2.0/24(rw,insecure,fsid=0,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Movies 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/show_33 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/show_34 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations/show_1 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations/show_2 192.168.2.0/24(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > > I also have tried 'crossmnt' instead of 'nohide' as I'm using a subnet and that appears to be problematic at times. > /home/user/media/ 192.168.2.0/24(rw,insecure,fsid=0,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Movies 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Series 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Series/show_33 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Series/show_34 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations/show_1 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations/show_2 192.168.2.0/24(rw,insecure,crossmnt,no_root_squash,no_subtree_check,async) > > Same result. > > I also have tried 'nohide' and then specified only the client IP instead of subnet info. > /home/user/media/ 192.168.2.101(rw,insecure,fsid=0,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Movies 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/show_33 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/show_34 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations/show_1 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > /home/user/media/Series/Animations/show_2 192.168.2.101(rw,insecure,nohide,no_root_squash,no_subtree_check,async) > > Also does not work. > > In all the above scenarios I manage to mount on client side: > sudo mount -t nfs 192.168.2.3:/home/user/media/ /home/jarvis/Videos/xbmc > > but when i try to mount in any of the above described scenarios i get timeout e.g.: > > sudo mount -t nfs 192.168.2.3:/home/user/media/Movies /home/jarvis/Videos/xbmc/Movies > > What I would want is to only mount the parent export on the client side, e.g.: > sudo mount -t nfs 192.168.2.3:/home/user/media/ /home/jarvis/Videos/xbmc > and have all directories/files that are available on the server side under '/home/user/media/' to be available on client side under '/home/jarvis/Videos/xbmc' as I have with samba at the moment > > how to achieve this? > -- > To unsubscribe from this list: send the line "unsubscribe linux-nfs" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
