Installation of Wheezy on a Dell Latitude E6320 [SSD Only]
Hello dear Debian user reading me,
I've been struggling with this configuration for the past few days (2,5)
before I decide to post here. Hopefully this will be the right place?!
So here are the physical elements of my story:
Machine => Dell Latitude E6320
With a single SSD such as :
Model Family: JMicron based SSDs
Device Model: KINGSTON SVP100S2128G
Serial Number: <censored>
Firmware Version: CJRA0202
The Goal: Installation of Debian Wheezy on a single SSD (No HDD available)
Issue: Under 'heavy' file system activity like aptitude installation of
larger packet let say for instance Xorg or whatever. The system then
fall into a kind of lockup with numerous sda2 (ext4)I/O errors and even
powerdown button can't be used for the shutdown unless keeping it
pressed...Let says the fs goes into survive mode like ro and therefore
not much can be done then!
On next reboot everything seems OK unless attempting same intensive fs
manipulation.

Installation procedure:
Downloaded and burned to USB drive then booted a "Live" version
debian-7.7.0-amd64-netinst.iso.
DISTRIB_ID=Debian
DISTRIB_DESCRIPTION="Debian GNU/Linux installer"
DISTRIB_RELEASE="7 (wheezy) - installer build 20130613+deb7u2+b3"
X_INSTALLATION_MEDIUM=cdrom
USB Stick for install was formatted VFAT and burned as follow:
$ sudo dd if=debian-7.7.0-amd64-netinst.iso of=/dev/sdc
$ sudo sync
Customization on targeted machine based on
https://wiki.debian.org/SSDOptimization and other googled findings:
i.e.: fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation

tmpfs /var/spool tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
then applied change as well with
$ sudo update-initramfs -u -k all
added /etc/sysctl.d/local.conf such as:
root@Fr-pr-DellE6320:/etc/sysctl.d# cat local.conf
vm.swappiness=1
root@Fr-pr-DellE6320:/etc/sysctl.d#
Changed also defaulted RAMDISK configuration to reduce SSD write frequency:
root@Fr-pr-DellE6320:/etc/default# cat tmpfs | grep RAM
RAMLOCK=yes
#RAMSHM=yes
RAMTMP=yes
# the root filesystem (overriding RAMTMP).
root@Fr-pr-DellE6320:/etc/default#

If you went there, it's probably because you may have a good idea of
what need to be done to make it work. Hopefully this is doable, if it's
not and your advise is to use a HDD thanks in advance but I already saw
that similar comments elsewhere. I'm just looking for a working solution
with a single SDD ;-)
Many thanks, looking forward reading good news.

JL
