Which file system do you use and why?

Though not to start a flame war. I used ext2 on my Phison SSDs in my eeepc 900 and 701sd when installing linux with no swap. I have since sold the 900 and am selling the 701sd currently. I have had them and used them for quite a while and have never had a problem with this setup configuration.

Not all SSD drives are equal. I might catch flak for this but my reasoning was better safe than sorry. Costs too much for fubar.

Posting from a Linux install right now installed on a 128MB SD Flash card.

The SSDs in these machines are crap, no question, cheap and slow without the sophisticated mechanisms of modern SSDs. I still have a 701 and I wouldn't use journaling on that.

Sorry for the OT request, but how was the following report produced?

This is what the SSD in my main machine reports

Code:

  9 Power_On_Hours_and_Msec 0x0032   085   085   000    Old_age   Always       -       13164h+12m+59.350s
231 SSD_Life_Left           0x0013   100   100   010    Pre-fail  Always       -       0
241 Lifetime_Writes_GiB     0x0032   000   000   000    Old_age   Always       -       2866

As you can see, after 13000+ hours and 2.8TB written to it it still reports 100% life left.

Looks like a "sudo smartctl -a /dev/sda" or similar.

Note that not all SSD devices support attributes like "SSD_Life_Left", so ymmv.

Hi,

People should not mix information between SSD generations. Older SSD do not have the capability of new SSD. First the type of cell used to store on SSD is not the same as on older generation drives. Controller for newest generation SSD handle information differently than older controllers. Older designs did not provide/support TRIM which can be provided by current kernels for newer SSD.

I still have some older 2nd generation SSD Intel drives that are under continuous use with no issues. Prices are falling for larger capacity consumer SSD so I will get a few more for personal use. I like OCZ & Patriot drives for their durability, cost and use of SandForce controllers for new generations.

You can use ext4 without journal

Code:

mkfs.ext4 -O ^has_journal /dev/sdXYZ

I'd say it's better than ext2 because it has all the newer technology of ext4. ext2 is probably still good for compatibility though.

Do I do this prior to installation or can I still do it after slackware is installed?

ReaperX7 · 10-08-2013, 10:07 PM

You can do it before.

Prior. With mkfs command you are formating the partition.

What about TRIM support?

JFS has TRIM support since kernel 3.7, so that is not a problem.

I'm not running Slackware as I type this, but it doesn't matter because I use ext4 on the root and home partitions regardless of which distro I'm running at any given moment. I stick with ext4 because it has always worked well for my own needs. My /boot stuff gets mounted on FAT32 partitions because UEFI seems to like them.

I have to correct myself, I found a downside. JFS can grow the filesystem, but has no option to shrink it. I just wanted to shrink the file-system to make space for a new partition, but this is not possible. I think I will change the filesystem on this one again, but look into those options before I decide for which i go.

How do you deal with /boot/initrd-tree on FAT32 and symlinks inside /boot?

kooru · 10-10-2013, 03:47 AM

ext4 for all partititions but i want to try btrfs.
