Another ZFS NFS question

[teremalex]

Hello everyone, I've looked through all the questions about ZFS share through NFS and did not found any solution of my problem. I am creating ZFS share on freeBSD14 and then trying to mount it on MacOS. So here is the /etc/rc.conf

hostname="zfscheck"
ifconfig_em0="DHCP"
sshd_enable="YES"
ntpd_enable="YES"
ntpd_sync_on_start="YES"
moused_nondefault_enable="NO"
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="NO"
zfs_enable="YES"

nfs_server_enable="YES"
nfsv4_server_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"

Here is the /etc/exports

V4: /public

Here is the df

Here is the "zfs get sharenfs"

zroot/var/mail          sharenfs  off                      default
zroot/var/tmp           sharenfs  off                      default

So I have 2 datasets which are public_dataset and everyone_dataset which are mounted on the root of filesystem and they are "chmod -R 777" and these datasets are shared through NFSV4. When I try to mount it with Finder in mac with string "nfs://192.168.1.165" it mounts it always with "/" sign and always public_dataset. If I try to "nfs://1982.168.1.165:/everyone" it refuses to mount anything

When I try to mount it from console I'll get

mount -t nfs 192.168.1.165:/public /Volumes/public
mount_nfs: can't mount /public from 192.168.1.165 onto /Volumes/public: No such file or directory
mount: /Volumes/public failed with 2

Could anyone explain how to differentiate between 2 shares of zfs to mount only one of them

Here is the /etc/exports

Your /public is now the 'root' of your exports.

mount -t nfs 192.168.1.165:/ /Volumes/public

Make sense, thanks. And if I want to mount another dataset which is everyone_dataset, then what should I modify?

 

[SirDice]

I would create an /exports directory and put everyone and public under it. Then set V4: /exports, so you're exporting 192.168.1.165:/everyone and 192.168.1.165:/public.

Thanks a lot. I thought about it too - but is there any way to mount only specific dataset? I do understand that I can chmod and refuse some users to open specific folders

 

[SirDice]

but is there any way to mount only specific dataset?

Well, you can mount one or both, so I'm not quite sure what you're asking? Just because they're both exported doesn't mean a client system has to mount them all.
