My collection of hints, tips and tricks (supporting my memory and maybe also helping others) - some links are in German, some in English



  • a manual autorun.sh should not be necessary - /etc/rcS.d/QS109Entware-ng should start Entware-ng, and /opt/etc/init.d/rc.unslung starts all /opt/etc/init.d/S* scripts
 ubiattach -m 6 -d 2
 /bin/mount -t ubifs ubi2:config /tmp/config
 vi /tmp/config/autorun.sh
 chmod +x /tmp/config/autorun.sh
 echo .
 echo "unmounting /tmp/config..."
 umount /tmp/config
 ubidetach -m 6
  • manual start (if auto-start does not work):
    • SSH: /share/CACHEDEV1_DATA/.qpkg/Entware-ng/Entware-ng.sh start
    • Desktop: open Entware-ng App in QNAP

HDD spin down issues

  • Qnap QTS write to disk at least every ~30 minutes ( setcfg -> dirtied inode ... qid_persistent.conf) on md9 )
Qnap seems to known this problem - see https://forum.qnapclub.de/thread/40517-3-sammelthema-probleme-mit-festplatten-standby-1-beitrag-beachten/?pageNo=12

Move Samba tdb_path to ramdisk

(Permanently) move samba's tdb_path to ram disk -> avoid hdd spin up due to .tdb file update

 [/] # /sbin/setcfg "Samba" "tdb_path" "/"                              
 [/] # /etc/init.d/smb.sh restart                                
 Restarting SMB services:
 Shutting down SMB services: smbd nmbd.
 Shutting down winbindd services: winbindd.
 locks path was set to /share/CACHEDEV1_DATA/.locks

Firmware downgrade

4.3.3 caused too many problems for me , so I downgraded to 4.2.5 (http://qnapsupport.net/qnap-firmware-downgrade/):

  • HDD did not spin down - at least not for long (setcfg wrote to disk every ~30 minutes)
  • LAN conenction frequently lost (less frequently after disabling cloudlink, but still happened...)
