OpenSolaris : Exporting a ZFS filesystem with CIFS

November 11th, 2009 by Stephane Kattoor

If you need to export ZFS volumes through CIFS, follow this simple step by step procedure.

Step 1 : install the packages

(This step is optional if you already have them installed on the machine)

kattoo@backup3:~$ pfexec pkg install SUNWsmbskr
DOWNLOAD                                  PKGS       FILES    XFER (MB)
Completed                                  2/2       35/35      2.0/2.0 
 
PHASE                                        ACTIONS
Install Phase                                  90/90

At this point, you’ll need to perform a reboot (if you can’t afford that, check in the references for a link to the full procedure).

Step 2 : Join a WORKGROUP

kattoo@backup3:~$ pfexec smbadm join -w SAKANA
After joining SAKANA the smb service will be restarted automatically.
Would you like to continue? [no]: yes
Successfully joined SAKANA
kattoo@backup3:~$

Step 3 : Set passwords for users who will access the shares

Add the following line into /etc/pam.conf :

^?View Code TEXT

1 2	kattoo@backup3:~$ grep smb /etc/pam.conf other password required pam_smb_passwd.so.1 nowarn

Now reset the passwords for the users who will be access the shares :

^?View Code TEXT

kattoo@backup3:~$ pfexec passwd kattoo
New Password: 
Re-enter new Password: 
passwd: password successfully changed for kattoo

Step 4 : Share the filesystems

You can then share any zfs filesystem with the following :

^?View Code TEXT

1	kattoo@backup3:~$ pfexec zfs set sharesmb=on backup

To check what is exported, you can do this :

^?View Code TEXT

kattoo@backup3:~$ sharemgr show -pv
default nfs=()
zfs
    zfs/backup smb=()
	  backup=/backup
	  backup_roadrunner=/backup/roadrunner
	  backup_thekla=/backup/thekla
    zfs/storage smb=()
	  storage=/storage
kattoo@backup3:~$

Here, the backup_roadrunner and backup_thekla were automatically exported because the property sharesmb was inherited from backup.
