Projekt Qnap

History of my QNAP TS-419PII

• Started with 2 disks WD20EARX as RAID1 2012-01-14

• Added another WD20EARX at 2012-01-31

[2 disk raid1 to 3 disk raid5 failed?]

• Discovered high Load_Cycle_Count. This fix needs optware QPKG

ipkg update
ipkg install make
ipkg install gcc # neded?
cd /tmp
wget http://dfn.dl.sourceforge.net/project/idle3-tools/idle3-tools-0.9.1.tgz
tar xzvf idle3-tools-0.9.1.tgz
cd idle3-tools-0.9.1
CC=gcc make
./idle3ctl -g105 /dev/sd[abc]

./idle3ctl -s300 /dev/sdc
# unplug sdc, wait for qnap to ack
# replug sdc, wait for resync to finish
# repeat for sda and sdb

• no smartctl (only get_hd_smartinfo) and the one provided by ipkg just segfaults -> compile my own

ipkg install grep 
ipkg install gawk 
ipkg install optware-devel # needed?
export PATH=/opt/bin:$PATH
wget http://heanet.dl.sourceforge.net/project/smartmontools/smartmontools/5.42/smartmontools-5.42.tar.gz
tar xzvf smartmontools-5.42.tar.gz
cd smartmontools-5.42
./configure
make
make install
# -> same problem, try dev trunk (later try older version?)
cd /tmp
svn co https://smartmontools.svn.sourceforge.net/svnroot/smartmontools/trunk/smartmontools smartmontools
cd smartmontools
./autogen.sh
# -> fails because perl does not work. Seems ipkg is missing libperl. Reported on freenode #nslu2-general

build 5.38 from tar and execute smrtctl works (5.39 - 5.42 do not)

• missing home directory

mkdir -p /share/homes/joachim
chown joachim /share/homes/joachim
ln -s /share/joachim /share/homes/joachim/share
cp /root/.profile /root/.bashrc /share/homes/joachim
# edit ps1 and add /opt/bin to PATH in .profile

• no sudo

ipkg install sudo
# copy admin lines in /etc/passwd /etc/shadow for root
add file /opt/etc/sudoers.d/joachim with content "joachim ALL = (root) ALL" and permissions 0440

• perl is missing libperl

# use perl from other repo
wget http://ipkg.nslu2-linux.org/feeds/optware/cs05q1armel/cross/stable/perl_5.10.0-6_arm.ipk
# fix md5sum to quiece ipkg
md5sum perl_5.10.0-6_arm.ipk # -> db8d74945234dd9cfb0b848c7601e6fe
vi /opt/lib/ipkg/lists/cs08q1armel # find line "Package: perl" and replace the md5sum
ipkg install perl_5.10.0-6_arm.ipk
