  31       <div class="body">
  32         <p>Today I switched to
  33 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
  34 new laptop</a>.  I've previously written about the problems I had with
  35 my new Thinkpad X230, which was delivered with an
  36 <a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
  37 GB Intel SSD disk with Lenovo firmware</a> that did not handle
  38 sustained writes.  My hardware supplier have been very forthcoming in
  39 trying to find a solution, and after first trying with another
  40 identical 180 GB disks they decided to send me a 256 GB Samsung SSD
  41 disk instead to fix it once and for all.  The Samsung disk survived
  42 the installation of Debian with encrypted disks (filling the disk with
  43 random data during installation killed the first two), and I thus
  44 decided to trust it with my data.  I have installed it as a Debian Edu
  45 Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
  46 server at home using Kerberos and LDAP, and will use it as my work
  47 station from now on.</p>
  48
  49 <p>As this is a solid state disk with no moving parts, I believe the
  50 Debian Wheezy default installation need to be tuned a bit to increase
  51 performance and increase life time of the disk.  The Linux kernel and
  52 user space applications do not yet adjust automatically to such
  53 environment.  To make it easier for my self, I created a draft Debian
  54 package <tt>ssd-setup</tt> to handle this tuning.  The
  55 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
  56 for the ssd-setup package</a> is available from collab-maint, and it
  57 is set up to adjust the setup of the machine by just installing the
  58 package.  If there is any non-SSD disk in the machine, the package
  59 will refuse to install, as I did not try to write any logic to sort
  60 file systems in SSD and non-SSD file systems.</p>
  61
  62 <p>I consider the package a draft, as I am a bit unsure how to best
  63 set up Debian Wheezy with an SSD.  It is adjusted to my use case,
  64 where I set up the machine with one large encrypted partition (in
  65 addition to /boot), put LVM on top of this and set up partitions on
  66 top of this again.  See the README file in the package source for the
  67 references I used to pick the settings.  At the moment these
  68 parameters are tuned:</p>
  69
  70 <ul>
  71
  72 <li>Set up cryptsetup to pass TRIM commands to the physical disk
  73     (adding discard to /etc/crypttab)</li>
  74
  75 <li>Set up LVM to pass on TRIM commands to the underlying device (in
  76     this case a cryptsetup partition) by changing issue_discards from
  77     0 to 1 in /etc/lvm/lvm.conf.</li>
  78
  79 <li>Set relatime as a file system option for ext3 and ext4 file
  80     systems.</li>
  81
  82 <li>Tell swap to use TRIM commands by adding 'discard' to
  83     /etc/fstab.</li>
  84
  85 <li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
  86
  87 <li>Run fstrim on every ext3 and ext4 file system every night (from
  88     cron.daily).</li>
  89
  90 <li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
  91     to 50 to reduce the kernel eagerness to swap out processes.</li>
  92
  93 </ul>
  94
  95 <p>During installation, I cancelled the part where the installer fill
  96 the disk with random data, as this would kill the SSD performance for
  97 little gain.  My goal with the encrypted file system is to ensure
  98 those stealing my laptop end up with a brick and not a working
  99 computer.  I have no hope in keeping the really resourceful people
 100 from getting the data on the disk (see
 101 <a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
 102 Thus I concluded that adding the discard option to crypttab is the
 103 right thing to do.</p>
 104
 105 <p>I considered using the noop I/O scheduler, as several recommended
 106 it for SSD, but others recommended deadline and a benchmark I found
 107 indicated that deadline might be better for interactive use.</p>
 108
 109 <p>I also considered using the 'discard' file system option for ext3
 110 and ext4, but read that it would give a performance hit ever time a
 111 file is removed, and thought it best to that that slowdown once a day
 112 instead of during my work.</p>
 113
 114 <p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
 115 this is already done by Debian Edu.</p>
 116
 117 <p>I have not yet started on the user space tuning.  I expect
 118 iceweasel need some tuning, and perhaps other applications too, but
 119 have not yet had time to investigate those parts.</p>
 120
 121 <p>The package should work on Ubuntu too, but I have not yet tested it
 122 there.</p>
 123
 124 <p>As for the answer to the question in the title of this blog post,
 125 as far as I know, the only solution is to replace the disk.  It might
 126 be possible to flash it with Intel firmware instead of the Lenovo
 127 firmware.  But I have not tried and did not want to do so without
 128 approval from Lenovo as I wanted to keep the warranty on the disk
 129 until a solution was found and they wanted the broken disks back.</p>

 150         <p>A few days ago, I wrote about
 151 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
 152 problems I experienced with my new X230 and its SSD disk</a>, which
 153 was dying during installation because it is unable to cope with
 154 sustained write.  My supplier is in contact with
 155 <a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
 156 replacement disk to try to fix the problem.  They decided to send an
 157 identical model, so my hopes for a permanent fix was slim.</p>
 158
 159 <p>Anyway, today I got the replacement disk and tried to install
 160 Debian Edu Wheezy with encrypted disk on it.  The new disk have the
 161 same firmware version as the original.  This time my hope raised
 162 slightly as the installation progressed, as the original disk used to
 163 die after 4-7% of the disk was written to, while this time it kept
 164 going past 10%, 20%, 40% and even past 50%.  But around 60%, the disk
 165 died again and I was back on square one.  I still do not have a new
 166 laptop with a disk I can trust.  I can not live with a disk that might
 167 lock up when I download a new
 168 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
 169 other large files.  I look forward to hearing from my supplier with
 170 the next proposal from Lenovo.</p>
 171
 172 <p>The original disk is marked Intel SSD 520 Series 180 GB,
 173 11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW:

 185
 186 <p>The only difference is in the first number (serial number?), ISN,
 187 SA, date and WNPP values.  Mentioning all the details here in case
 188 someone is able to use the information to find a way to identify the
 189 failing disk among working ones (if any such working disk actually

 243       <div class="body">
 244         <p>Half a year ago, I reported that I had to find a
 245 <a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
 246 for my trusty old Thinkpad X41</a>.  Unfortunately I did not have much
 247 time to spend on it, and it took a while to find a model I believe
 248 will do the job, but two days ago the replacement finally arrived.  I
 249 ended up picking a
 250 <a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
 251 with SSD disk (NZDAJMN).  I first test installed Debian Edu Wheezy as
 252 a roaming workstation, and it seemed to work flawlessly.  But my
 253 second installation with encrypted disk was not as successful.  More
 254 on that below.</p>
 255
 256 <p>I had a hard time trying to track down a good laptop, as my most
 257 important requirements (robust and with a good keyboard) are never
 258 listed in the feature list.  But I did get good help from the search
 259 feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
 260 allowed me to limit the list of interesting laptops based on my other
 261 requirements.  A bit surprising that SSD disk are not disks according
 262 to that search interface, so I had to drop specifying the number of
 263 disks from my search parameters.  I also asked around among friends to
 264 get their impression on keyboards and robustness.</p>
 265
 266 <p>So the new laptop arrived, and it is quite a lot wider than the
 267 X41.  I am not quite convinced about the keyboard, as it is
 268 significantly wider than my old keyboard, and I have to stretch my
 269 hand a lot more to reach the edges.  But the key response is fairly
 270 good and the individual key shape is fairly easy to handle, so I hope
 271 I will get used to it.  My old X40 was starting to fail, and I really
 272 needed a new laptop now. :)</p>
 273
 274 <p>Turning off the touch pad was simple.  All it took was a quick
 275 visit to the BIOS during boot it disable it.</p>
 276
 277 <p>But there is a fatal problem with the laptop.  The 180 GB SSD disk
 278 lock up during load.  And this happen when installing Debian Wheezy
 279 with encrypted disk, while the disk is being filled with random data.
 280 I also tested to install Ubuntu Raring, and it happen there too if I
 281 reenable the code to fill the disk with random data (it is disabled by
 282 default in Ubuntu).  And the bug with is already known.  It was
 283 reported to Debian as <a href="http://bugs.debian.org/691427">BTS
 284 report #691427 2012-10-25</a> (journal commit I/O error on brand-new
 285 Thinkpad T430s ext4 on lvm on SSD).  It is also reported to the Linux
 286 kernel developers as
 287 <a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
 288 report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
 289 (SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
 290 Lenovo forums, both for
 291 <a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430
 292 2012-11-10</a> and for
 293 <a href="http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147">X230
 294 03-20-2013</a>.  The problem do not only affect installation.  The
 295 reports state that the disk lock up during use if many writes are done
 296 on the disk, so it is much no use to work around the installation
 297 problem and end up with a computer that can lock up at any moment.
 298 There is even a
 299 <a href="https://git.efficios.com/?p=test-ssd.git">small C program
 300 available</a> that will lock up the hard drive after running a few
 301 minutes by writing to a file.</p>
 302
 303 <p>I've contacted my supplier and asked how to handle this, and after
 304 contacting PCHELP Norway (request 01D1FDP) which handle support
 305 requests for Lenovo, his first suggestion was to upgrade the disk
 306 firmware.  Unfortunately there is no newer firmware available from
 307 Lenovo, as my disk already have the most recent one (version LF1i).  I
 308 hope to hear more from him today and hope the problem can be
 309 fixed. :)</p>

 383 7.1+edu0~alpha3, based on Debian with codename "Wheezy".</p>

 385 <p><strong>About Debian Edu and Skolelinux</strong></p>
 386
 387 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
 388 Skolelinux</a>, is a Linux distribution based on Debian providing an
 389 out-of-the box environment of a completely configured school
 390 network. Immediately after installation a school server running all
 391 services needed for a school network is set up just waiting for users
 392 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 393 environment is prepared using PXE, so after initial installation of
 394 the main server from CD, DVD or USB stick all other machines can be
 395 installed via the network. The provided school server provides LDAP
 396 database and Kerberos authentication service, centralized home
 397 directories, DHCP server, web proxy and many other services. The
 398 desktop contains
 399 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 400 than 60 educational software packages</a> and more are available from
 401 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 402 and Xfce desktop environment.</p>
 403
 404 <p>This is the fourth test release based on Debian Wheezy. Basically
 405 this is an updated and slightly improved version compared to the
 406 Squeeze release.</p>
 407
 408 <p><strong>Software updates</strong></p>
 409 <ul>
 410   <li>Dropped ispell dictionaries from our default installation.</li>
 411   <li>Dropped menu-xdg from the KDE desktop option, to drop the Debian
 412     submenu.  It was not included with Gnome, LXDE or Xfce, so this
 413     brings KDE in line with the others.</li>
 414   <li>Dropped xdrawchem, xjig and xsok from our default installation as
 415     they don't have a desktop menu entry and thus won't show up in the
 416     menu now that menu-xdg was removed.</li>
 417   <li>Removed the killer system to kill left behind processes on
 418     multi-user machines, as it was no longer able to understand when a
 419     X display was in use and killed the processes of the active users
 420     too.</li>
 421   <li>Dropped the golearn (from goplay) package as the debtags in wheezy
 422     are too few to make the package useful.</li>
 423 </ul>
 424 <p><strong>Other changes</strong></p>
 425 <ul>
 426   <li>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
 427   <li>Multi-arch i386/amd64 USB stick ISO available.</li>
 428   <li>Got rid of ispell/wordlist related debconf questions that showed
 429     up for some language options.</li>
 430   <li>Switched to using http.debian.net as APT source by default.</li>
 431   <li>Fixed proxy configuration on Main Server installations.</li>
 432   <li>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
 433     d-i is doing it.</li>
 434   <li>Made sure root and user passwords were not left behind in the
 435     debconf database after installation on Main Server installations.</li>
 436   <li>Made Roaming Workstation dynamic setup more robust and added draft
 437     script setup-ad-client to hook a Roaming Workstation up to a
 438     Active Directory server instead of a Debian Edu Main Server.</li>
 439   <li>Update system to install needed firmware packages during
 440     installation, to work properly in Wheezy.</li>
 441   <li>Update system to handle hardware quirks (debian-edu-hwsetup).</li>
 442   <li>Corrected PXE installation setup to properly pass selected desktop
 443     and keymap settings to PXE installation clients.</li>
 444   <li>LTSP diskless workstations use sshfs by default, allowing them to
 445     work without adding them to DNS and NIS netgroups for NFS access.</li>
 446 </ul>
 447 <p><strong>Known issues</strong></p>
 448 <ul>
 449   <li>No mass import of user account data in GOsa (ldif or csv)
 450     available yet (698840).</li>
 451   <li>Artwork not enabled for all desktops.</li>
