FreeNAS, ZFS, User Quota, Samba

Task: Apply ZFS user quota to Smaba

Source:

zpool with samba user home folders: poolz2/samba/users

Allow request about quota for everyone:
zfs allow everyone userquota,userused poolz2/samba/users

Set usrer quota 120G for domain user : DOMAIN\username
zfs set userquota@"DOMAIN\username"=120G poolz2/samba/users

Tune SAMBA,  /usr/local/etc/smb4.conf:
get quota command = /mnt/poolz2/home/scripts/quota_get.sh %U %D

Reload SAMBA:
killall -HUP smbd 
Or change via GUI of FreeNAS
Example of GUI of SMB Services (FreeNAS11.2), add quota.

Soulution:

Script for get quota data: /mnt/poolz2/home/scripts/quota_get.sh
#!/bin/sh
rtype=$4
if [ "${rtype}" == -1 ]; then
 exit
fi
username=$1
if [ ! -z  "$username" ]; then
  domainname=$2
  requestpath=${PWD}
  DATASETNAME=`/bin/df -l ${requestpath} | /usr/bin/tail -n 1 | /usr/bin/awk '{ print $1 };'`
  info=`/sbin/zfs userspace -Hp ${DATASETNAME}  | /usr/bin/grep -i ${domainname}'\\\\'${username}`
  usedbytes=`echo ${info}| /usr/bin/awk '{ printf "%.f", $4/1024 };'`;
  quotabytes=`echo ${info}| /usr/bin/awk '{ if ( $5 == "none" ) { print "0"} else { printf "%.f", $5/1024 }  };'`;
  if [ "$quotabytes" != 0 ]; then
   echo 2 $usedbytes $quotabytes $quotabytes $usedbytes $quotabytes $quotabytes
  fi
fi
exit

Example of GUI of Sharing SMB (FreeNAS11.2).
Easy script for define default quota for all users. I plan run it just by cron.
#!/bin/sh

USERS_DATASET=poolz2/samba/users
DOMAINNAME=SOMEDOMAIN
DEFAULT_QUOTA=80G

/sbin/zfs allow everyone userquota,userused ${USERS_DATASET}
mountpoint=`/bin/df  -l ${USERS_DATASET} | /usr/bin/tail -n 1 | /usr/bin/awk '{ print $6 };'`
for file in ${mountpoint}/*; do
    USERNAME=$(/usr/bin/basename "$file")
    LOGON=${DOMAINNAME}\\${USERNAME}
    QUOTA=`/sbin/zfs get -H "userquota@${LOGON}" ${USERS_DATASET} | /usr/bin/awk '{ print $3 };'`
    #echo ${LOGON} : ${QUOTA}
    if [ "$QUOTA" == "none" ];then
        /sbin/zfs set "userquota@${LOGON}=${DEFAULT_QUOTA}" ${USERS_DATASET}
        #echo Was set default quota ${DEFAULT_QUOTA} for ${LOGON}
    fi
done

#/sbin/zfs userspace ${USERS_DATASET}
