General :: Looking For Best File System?
Jan 18, 2011
I'm looking for peoples opinion on which file system they use for their Linux platform and why?
I have used fat32, ext2,3,4 and I am currently back to using ext3.
I have been reading up on the subject. Opinions are diverse as they are plentiful.
Several websites I have found are interesting.
Ext3 and Ext4: Which file system to install? April 2009
Ext3 vs Ext4 April 2009
What is ext3?Oct2004
Wikipedia The ext4 or fourth extended filesystem ongoing
Heres a comparison chart of all the file systems. I had no idea there were so many :O
To be perfectly honest I can only understand bits and pieces of whats in these articles as they use some technical language that goes over this novices head. So I was wondering if someone could explain this in everyday terms that we all can understand?

I'm a little bit confused with partitioning the filesystem in Linux. the difference between creating the file system with fdisk and mkfs (when formatting the disk). I can't clearly tell my problem, so please look at this picture:

So 2 days ago everything was all fine on my machine. Has been for about a month, but all of a sudden as of yesterday I have no sound, I am seeing IRQ interupts on boot, During boot I am seeing file system is not clean, , and swap space is being used for the first time while doing normal task, etc. These are 2 new hard drives in RAID 1 with ReiserFS. I should have used a newer FS but thats a whole other argument.
Anyways here we go.
The system is Debian Lenny amd64
Physical RAM 4GB + 6GB swap
/var/log/messages
Code:
Feb 21 07:35:09 Sarah kernel: imklog 3.18.6, log source = /proc/kmsg started.
Feb 21 07:35:09 Sarah rsyslogd: [origin software="rsyslogd" swVersion="3.18.6" x-pid="3994" x-info="http://www.rsyslog.com"] restart
code....

I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.

my partitioning layout was as follows
Vista Recovery
Windows 7
GRUB
Extended
-->Fedora 12 (ext4)
so, I shrunk my recovery in Windows 7 successfully, and booted into my Fedora 12 live cd to run Gparted, and move the partitions so that the free space could go towards fedora, I did such, and then I couldn't expand the partition to my dismay. Next, I woke up this morning, tried to boot to fedora to run SSH, grub loaded, but when I tried to boot fedora, I got the "File system check failed" error, and when I tried 7, it just went to a blank screen with a single "_" in the top left-hand corner.

I have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab
Code:
/dev/sda3 /windows ntfs-3g defaults,nosuid,nodev,umask=000 1 0
Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.

I used the ext3 format when I formatted my partition prior to installing Ubuntu10.10. I had accidentally deleted a file and began the process to get it back. It wasn't critical but helpful to recover the file. To make a long story short I ran into to some unexpected road blocks. I tried to use PhotoRec to get the job done but with no success.
I'm just looking down the road in the event I might have to recover something important.If it would be better going back to the Fat32 file system I would rather do it sooner than later. Just as a side note I am dual booting between linux and windows.

I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.
"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"
Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).

My Redhat Enterprise Linux 4 with 6x partitions (/, /boot,/home, /usr, /var, /tmp) of 6.0 GB IDE Hardisk was working quite fine. I decided to create LVM on /home and /var partitions but due to some errors occured and I delete the /home partitions. That's why partition table altered. I then delete 4,5,and 6th partitions (/home, /var, /tmp) partitions and now try to create one by one but following error is coming:-

Have just assembled a new computer and thought I would install the 64 bit version of openSUSE 11.2 in a "Windows free zone". After a hiccup or two I have managed to get a system of sorts running but on trying to copy files from my old computer(via a memory stick) it tells me that Vfat is an unknown file system.On my old computer I am running 32 bit openSUSE 11.2 as a dual boot system with Windows XP and have no problems moving files between the two different file systems.Is it possible to get a 64 bit file system to read 32 bit file system drives and if so how do I do it?

I have downloaded DavMail and its currently living and running from my /home/user/Downloads/DavMail
in this folder is
davmail.jar
davmail.log
davmail.sh
Lib/
[Code]....
I need to put davmail in a better location than downloads but am unsure where to put it, Im guessing if I seperate some of the files/folders such as lib ill have to modify the davmail.sh file.
wheres the best location to keep this or should it remain in my home folder, I was going to put this in
/usr/local/bin
/usr/local/lib
But the jar count as a binary? the .sh certainly wouldnt.

I'm still to install Linux (waiting for a replacement of a bad DIMM) on my new box. It will probably be CentOS, following 'Rubberman's recommendation in forum/coffee-lounge/166195-distro-recommendation-development-use.html .
I assume (as I haven't installed Linux before) there could be a choice of file systems. Is there any recommendation on what I should/could use ?

I need to use MFix a open source program Therefore, because i don't have Linux on my computer i use Cygwin_NT-5.1 the latest version. From the help desk they told me that i need to configure a file to fit with my system. I just changed operation system to CYGWIN_NT-6.0 (instead of the command uname -s ; set opsys=$1. this was the only way i had an idea to do it, so i tell the programm that my sytem is a 6.0 but it isn't
then i wanted to install mfix and it gives me the error
../../model/make_mfix: line 119: syntax error near unexpected token '('
../../model/make_mfix: line 119: 'echo -n "Do you need debug version? (y/n) [no] "'
by looking in he make_mfix file it looks like this echo -n "Do you need debug version? (y/n) [no] "

i just installed Fedora 12 (via vbox 3.1.4). stupidly i started with 8G and, of course, ran out of space on the / filesystem. i added 8G to the drive which now shows as 17G.based on the below outputs, it looks like i have 8G more space available on the drive. based on reading other posts it looks like i need to use parted to increase the size but not sure how to do that.

Is there a way to use JFFS2 (or other journaling file system) on an HDD? I'm looking for a file system feature that doesn't overwrite previously written data on an HDD.
Reason I'm asking is I'd like to use the capacity of the HDD as a log of all written activity, with the ability to retrieve old files. i.e. all writes to the HDD would be sequential.

What are the directories and files in Unix file-system that has default user permission set. For eg. home directory of a user can't be seen by the other users on the system without his permission. In the same way what are the other directories that by default has user permission set at the time user account has opened. Eg. /etc,/bin or what
