F11: SSD Optimizations?

Does anyone have any comments on optimizing Fedora 11 for SSD systems?

In Fedora 10 it was recommended to convert the default EXT3 filesystem to a non-journaling EXT2. What about with F11's default EXT4? It's my understanding that it's possible to use the EXT4 in a non-journaling mode but I don't know how that would be done. I presume that the boot partition would remain EXT3, and that should not necessarily be a problem?

There was also an F10 (and Linpus) SSD speedup mod to the grub.conf file that I presume would be appropriate in F11 as well? As well as some optimizations to /etc/fstab and etc/rc.d/rc.local. (see http://jorge.fbarr.net/2008/11/10/fedora-10-on-the-acer-aspire-one/).

I'll be interested in others' comments. I'm running an A110 with 8GB SSD and 512MB ram.

The F10 notes to which you refer include a bit on having to re-set the partitions to ext2 because, even if you select ext2 during install, this is ignored. From what I have read elsewhere, this is a quirk with the USB install.

I ran a DVD install from an external player and as part of the disk setup, I changed the partition types to ext2 and this stuck ao I did not have to fiddle around later.

With regards to the F10 optimisations for SSD (noatime, elevator and other conf settings - I put all this in place and everything's working. I did notice that the 'disk' (SSD) on my AA1 went 'full on' a few times for about 1 minute or so during the first couple of days but it has not done so since (I have 1.5GB RAM and it was not swapping) - I wonder if something was indexing man pages or something like that?

Overall I am very pleased with F11 on the AA1 - even running Gnome the system's pretty responsive. So far I have got the following running:

• VPNs by installing networkmanager-pptp
  aMSN
  Thunderbird
  RDP,VNC clients with tsclient,
  Twinkle SIP phone
  VLC
  mysql-query-browser for database work
  Bluefish editor
  Filezilla
  Gnome, XFCE4 and LXDE desktops with cubed workspaces

Right SD slot is working, but left one isn't - this is annoying as the click-lock on the right one is broken so I have to hold the cards in!
Wireless switch and LEDs are not working but I'm not in a rush for those.
I'm tempted to replace an old laptop with another netbook with a 10" screen -provided I don't have to buy Windows or I can get a refund

 

I've been using F11 for some time now (running rawhide until it came out). And i'm using ext4 because it's faster than ext2 and after install you can disable journaling on ext4 by going into init 1 and mount your filesystem to read-only, and then run: "tune2fs -O^has_journal /dev/sda<partition>"

 

can you explain in details.

Where is init1 and how to go there? others are clear to me

 

Init 1 means booting into singleuser, non-graphic, mode which is realy basic and starts only the necessary programs.
You can get there by going into grub when booting and doing a 1 time mod on the boot line.

Grub can be reached by holding the TAB key while booting. It will show you the boot menu and then you edit the fedora boot option, there you will see the 3 lines grub will load when booting. If you edit the second line (which loads the kernel) and add a " 1" at the end you will get into init1 when you boot this time.

 

I discovered a writeup similar to F10 install instructions for the AAO but for F11 which address some of my original question:
http://jorge.fbarr.net/2009/06/11/fedora-11-on-the-acer-aspire-one/
I now have F11 XFCE running on my 8GB SSD 512MB A110. Everything seems to work so far except for the wireless LEDs (and maybe the switch), and I had some initial audio problems before doing the changes recommended in the writeup above.
I haven't done anything about the journaling EXT4 yet though.

Yo,

I posted this on another thread moments ago, I followed the instructions on http://jorge.fbarr.net/2009/06/11/fedor ... spire-one/ and he explained how to disable journaling (too many disk writes for SSD)

I did it, because it took me no time and I would rather be safe than sorry, BUUTTT, I think this may be much ado about nothing,

IMO an SSD will have the same lifespan as an HD, a good one (99.9% of them) will outlast the computer, and a bad one will fail whenever.

 

i followed this how-to and got a wonderful F11xfce on my aspire.one!

the instructions on the page mentioned give full explanation on how to use the ssd version the best way.

fast boot, responsive, just the Fedora I'm used to but then small screen size. I just skipped the anti-journaling part because it gave trouble installing F10 from the same jorge.fbarr...

F11xfce for me is a great replacement for linpus. linpus is good and usable but not fully under my control (or it is hidden).

for half a year I am very pleased with Fedora 10 on my big laptop (acer aspire 1640). being a noob I must say Fedora and all the instructions on the net are very supportive leaving the other platform for ever!
