lol, funny how typing something out/writing down a problem can help you solve it sometimes!
Anyway, just in case someone else gets the same error message "below nearest filesystem" when trying to mount NFS, I'm going to post the symptoms and the solution - no point wasting all this typing!
| Quote: | Hi, I'm having a problem mounting an exported directory from another computer (server) which on the server is mounted from secondary hard drive. Mounting other points off the server which do not contain mounts under it off of another device works fine.
my mount attempt:
| Code: | auron root # mount -v /mnt/backupDir
mount: server:/mnt/backupDir failed, reason given by server: Permission denied |
server says:
| Code: | Feb 20 04:35:53 mog rpc.mountd: authenticated mount request from auron:690 for /mnt/backupDir (/)
Feb 20 04:35:53 mog rpc.mountd: request to export directory /mnt/backupDir below nearest filesystem / |
but this works:
| Code: | mount server:/ temp -v
mount: no type was given - I'll assume nfs because of the colon
server:/ on /root/temp type nfs (rw,addr=192.168.1.5)
auron root # ls temp/
.fetchids dev home mnt razor-agent.log tmp
bin etc lib opt root usr
boot grub lost+found proc sbin var
auron root # ls temp/mnt/backupDir/
auron root # |
temp/mnt/backupDir/ should contain (this is obtained by ssh'ing into the server):
| Code: | mog root # ls /mnt/backupDir/
daily hello weekly |
my relavent fstab:
| Code: | | server:/mnt/backupDir /mnt/backupDir nfs auto,ro |
server relavent exports:
| Code: | | / auron(sync,rw,no_root_squash) |
server relavent fstab:
| Code: | | /dev/hdd1 /mnt/backupDir auto auto,rw |
| Code: | mog root # mount
/dev/hdb3 on / type ext3 (rw,noatime)
none on /proc type proc (rw)
none on /dev type devfs (rw)
tmpfs on /dev/shm type tmpfs (rw)
/dev/hdd1 on /mnt/backupDir type ext3 (rw)

I'm sure this used to work, but no longer does - what am I missing? what do i have to turn on to enable a computer to mount something "below nearest filesystem"?
Googling for "below nearest filesystem" turns up nothing (this forum as well).
I had a look in the source code, and this error is thrown when something like the devices are not equal...
Must I export that directory seperatly? |
omg, lol, I just thought of this idea as i was typing "Must I export that directory seperatly?" And it turns out that was what fixed it!
I just changed my exports to this:
| Code: | / auron(sync,rw,no_root_squash)
/mnt/backupDir auron(sync,rw,no_root_squash) |
And now I can mount it successfully!
However, ls'ing on temp/mnt/backupDir still show's up nothing,
But if i mount server:/mnt/backupDir directly to another location, I can get the listing and access it fine...
Hmmm, interesting.... |
