NFS "all directories" not working

[Kai Timmer]

Hello,
I have a lot of ZFS datasets (one for every host) under /mnt/backups and I want to create only one nfs share so that all my hosts are allowed to mount their dataset.

So I created a share for /mnt/backups and checked the "all directories" box.

Now, when I try to mount /mnt/backups/host1 from a host, I get this:

Code:

root@test3:/home/kait# mount -vvv -t nfs -o rw,timeo=60,retrans=20,proto=udp,vers=3,bg,soft,intr freenas.local:/mnt/backups/host1/ /backup/
mount: fstab path: "/etc/fstab"
mount: mtab path:  "/etc/mtab"
mount: lock path:  "/etc/mtab~"
mount: temp path:  "/etc/mtab.tmp"
mount: UID:        0
mount: eUID:       0
mount: spec:  "freenas.local:/mnt/backups/host1/"
mount: node:  "/backup/"
mount: types: "nfs"
mount: opts:  "rw,timeo=60,retrans=20,proto=udp,vers=3,bg,soft,intr"
mount: external mount: argv[0] = "/sbin/mount.nfs"
mount: external mount: argv[1] = "freenas.local:/mnt/backups/host1/"
mount: external mount: argv[2] = "/backup/"
mount: external mount: argv[3] = "-v"
mount: external mount: argv[4] = "-o"
mount: external mount: argv[5] = "rw,timeo=60,retrans=20,proto=udp,vers=3,bg,soft,intr"
mount.nfs: trying text-based options 'timeo=60,retrans=20,proto=udp,vers=3,bg,soft,intr,addr=10.2.1.12'
mount.nfs: prog 100003, trying vers=3, prot=17
mount.nfs: trying 10.2.1.12 prog 100003 vers 3 prot UDP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 10.2.1.12 prog 100005 vers 3 prot UDP port 745
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting freenas.local:/mnt/backups/host1/

But this works:

Code:

mount -t nfs -o rw,timeo=60,retrans=20,proto=udp,vers=3,bg,soft,intr freenas.local:/mnt/backups/ /backup/

What did I miss?

That each dataset is its own filesystem.
