[SOLVED] Can't see home folder on one NFS mount but can in another mount on another share
Hello,
I have a few Ubuntu 9.10 laptops I'm trying to learn NFS sharing with. I am just experimenting on this right now, so no harsh words about the security of what I'm playing with, please
toshiba-laptop:/home/woodnt/Homeschool on /mnt/mnt1 type nfs (rw,addr=192.168.1.54)
toshiba-laptop:/home/share/HomeSchool on /mnt/mnt2 type nfs (rw,addr=192.168.1.54)
toshiba-laptop:/HomeSchool on /mnt/mnt3 type nfs (rw,addr=192.168.1.54)
toshiba-laptop:/ on /mnt/mnt4 type nfs (rw,addr=192.168.1.54)
toshiba-laptop:/home on /mnt/mnt5 type nfs (rw,addr=192.168.1.54)
on the host machine, /bin and /home have the same permissions:
Code:
woodnt@toshiba-laptop$ ls -dl home bin
drwxr-xr-x 2 root root 4096 2009-12-22 23:21 bin
drwxr-xr-x 16 root root 4096 2009-12-23 20:45 home
also on the host machine /home/woodnt and /HomeSchool have the same permissions:
woodnt@luke-netbook:/mnt/mnt4$ ls -ld bin bin/bash
drwxr-xr-x 2 root root 4096 2009-12-22 23:21 bin
-rwxr-xr-x 1 root root 917960 2009-09-14 00:08 bin/bash
woodnt@luke-netbook:/mnt/mnt4$ ls home
woodnt@luke-netbook:/mnt/mnt4$
And I can see /bin, everything in /bin like /bin/bash, but not /home and any home contents.
I have the same GID and UID on both boxes (1000, not that that matters).
On the client with everything mounted as above, I can:
ls the contents of /bin, /home (via /mnt/mnt5), /, /home/woodnt/Homeschool/, /home/share/HomeScool, and /HomeSchool.
When I am on the mountpoint /mnt/mnt4 where the whole root directory is mounted and I " $ ls /mnt/mnt4/home " I get bupkis. Nada. Zilch.
Why can I see /home mounted on /mnt/mnt5 but not as a subdir of / when from the /mnt/mnt4?
I'm the same user in the same group logged into the same mountpoints on every one, but I can see inside the host /home when it is mounted directly, but not when it is mounted as root and cd'd too.
What gives?
Thanks for the help in advance,
Narnie

I set it up similarly on the same computer exporting only the root (/) directory. Same problem. Can't be a user/group problem or permission problem because it is the same user on the same computer/
The mount of root is to /mnt/mnt1
Notice the permissions below. I even cp -a /bin/bash /home just to have the same file with the same permissions and yet I can't see bash in /mnt/mnt1/home
Really crazy. This is duplicated on another pair of computers setups as well. not just this computer and the netbook above.
Is /home in a separate files system to / (root)? If it is then NFS exporting root only exports the root filesystem. I wasn't absolutely certain about this but NFSExports < Webmin < TWiki says:
Quote:
If an exported directory has mount points under it, files under those mount points will not be accessible by NFS clients. So if you exported the root directory / and has a separate filesystem mounted at /home , you would need to also export /home and clients would need to mount it in order to see the files under it.

Well, you are sure right. /home is on a separate partition.
That totally explains it. I wish I'd thought to say that part of the equation. Thank you for pointing this out.
