Cookbook

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

Entware

• https://forum.qnapclub.de/thread/37886-howto-entware-ng-und-linux-pakete-installieren/?f=80&t=37886#p215810

autorun

• 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

• autorun.sh: based on http://www.welzels.de/blog/projekte/qnap-mods-tricks-und-projekte/optware-init-skripte-nach-booten-starten/
• installation for my 431p: (copy from https://wiki.qnap.com/wiki/Running_Your_Own_Application_at_Startup)

 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

• enable auto-start (re-do after FW update): http://www.welzels.de/blog/projekte/qnap-mods-tricks-und-projekte/optware-init-skripte-nach-booten-starten/

• 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

Raid sync speed

HDD spin down issues

• Why the hard drive of NAS does not go to standby mode?

• Probleme mit Festplatten-Standby

• Qnap QTS 4.3.3.0154 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:

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...)
