[Samba] smbcontrol reload & close-share not working like previous version
Hello. I just upgrade my kernel, smbd and changed my smb.conf. (4.14.12-1-Arch" to "4.14.19-1-lts") "samba 4.7.4-1" But now, "reload smbd" and "close-share" can not drop connected users to share. Because of that I have to restart smbd service for destroy a share right now. But it was working previous version and I don't know what is wrong right now. As you know, restarting SMBD affects other shares. This is dirty way to an easy job. When I try to destroy a share I follow these steps: 1- Edit smb.conf "delete include line" 2- Delete samba share conf (what is included) 3- smbcontrol smbd close-share 4- smbcontrol all reload-config or "systemctl reload smbd" 5- zfs destroy dataset This steps not working anymore because user still won't disconnect share until service restart. When I close a share I need to take out users from the share because when they still use the share I'm getting "busy" error when I try to destroy dataset. Any advice please? *smb.conf* [Global] netbios name = DEV2 server string = %h Test Host workgroup = sm realm =sm.pvt security = ADS server role = member server idmap config *: backend = tdb idmap config *: range = 90000001-100000000 winbind cache time = 7200 winbind offline logon = yes winbind nested groups = yes winbind use default domain = yes winbind refresh tickets = yes idmap config sm.pvt: backend = rid idmap config sm.pvt: range = 20000-90000000 encrypt passwords = yes dns proxy = no strict locking = Auto oplocks = yes deadtime = 15 logging = file max log size = 51200 log level = 2 load printers = no printing = bsd printcap name = /dev/null disable spoolss = yes unix charset = UTF-8 case sensitive = auto guest account = nobody map to guest = Bad User obey pam restrictions = yes ntlm auth = no allow trusted domains = no client ntlmv2 auth = yes kernel change notify = yes panic action = /usr/bin/samba-backtrace dns update command = /usr/sbin/samba_dnsupdate acl allow execute always = true dos filemode = yes multicast dns register = no domain logons = no client use spnego = yes local master = no domain master = no preferred master = no template shell = /bin/sh template homedir = /home/%D/%U max xmit = 65536 max open files = 232040 strict sync = no include = /etc/samba/shares/ssdpool.test.cifs *Share conf:* [test] path = /ssdpool/test guest ok =no browseable = yes writeable = yes hide dot files = yes veto files = /.snapshot/.windows/.mac/.zfs/ use sendfile = no acl group control = yes map acl inherit = yes inherit owner = yes inherit permissions = yes inherit acls = yes vfs objects = acl_xattr streams_xattr aio_pthread acl_xattr:ignore system acls = yes write cache size = 131072
