I created 3 partitions on my usb stick, one is vfat, one ist ntfs and one is ext4.And i formated them like this:
Code:
mkfs.vfat -F32 /dev/sdg1
mkfs.ext4 /dev/sdg2
[code]....
I need to allow non-root users to read/write on an ext3 partition.
Below is the relevant output from fdisk -l
Code:
The partition in question is /dev/sda4 and it is mounted as /Data (setup during installation).
With the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages
I switched a external 500GB usb HD from FAT to ext4, because the box it's on no longer has windows.It mounts fine and I can read it - but not write.I have some inkling as to what to do, but prefer your opinions first.

I had 5.4 machine. Upgraded to 5.5 today via yum upgrade. All went fine. Rebooted. Wanted to convert root partition to ext4 (I have three partitions: /boot, / and swap). All of them on software RAID 1 (root is /dev/md2). I did the following for converting
yum install e4fsprogs
tune2fs -O extents,uninit_bg,dir_index /dev/md2
nano /etc/fstab # I indicated here that my /dev/md2 is of ext4

Is there guide for converting ext3 to ext4 on Fedora? I use Fedora 12 which is regularly updated. How safe is procedure for data, I have only one ext3 partition on disk which has one ntfs and that ext3 partition (and also one small swap partition).

- What is Fedora's position on MONO & MoonLight?
- I will be leaving /home on my 600+ BGB HDD, but root, /usr & swap will be on my SSD- will there be any potential issues?
- What format should I use (Ext3, Ext4, XFS...) for my SSD?
- Any recommendation of rpm repo's I should add?

i want to give some permission to non root users so that they can mount drives without need of root password.
View 2 Replies View RelatedI just noticed on my Ubuntu machine (ext3 filesystem) that removing write permissions from a file does not keep root from writing to it. Is this a general rule of UNIX file permissions? Or specific to Ubuntu? Or a misconfiguration on my machine? Writing to the file fails (as expected) if I do this from my normal user account.Is this normal behavior?Is there a way to prevent root from accidentally writing to a file (Preferably using normal filesystem mechanisms, not AppArmor, etc.)
I understand that root has total control over the system and can, eg, change the permissions on any file.My question is whether currently set permissions are enforced on code running as root. The idea is the root user preventing her/himself from accidentally writing to a file. also understand that one should not be logged in as root for normal operations.
It has crashed or failed to install on a known good system for the 5th time now. I have never had that problem with fedora before. I am now installing with ext3 instead of ext4. I am hoping for better success with it and will update. I was able to try MinGW with WINE before the first crash and I liked what I saw there. Only hoping to be able to get a good install this time.
View 2 Replies View RelatedIs that possible, I mean when I upgrade F10 to F11 with yum upgrade is there a way to 'upgrade' the filesystem to ext4 for example (with the exception of boot partition)? Or I have to reinstall fedora like new?
While changing the filesystem can I do it by parts? what I mean is for example: I have 2 partitions like '/' and '/home' with ext3, so I backup data in '/home', change '/' to ext4 then mv files from '/home' to '/' and change '/home' to ext4 and finally mv those files from '/' to '/home'. Is that possible?
I upgraded F10 to F11 successfully.
Then I convert the / partition filesystem by the following steps:login as root user in multi user mode read [url], and execute tune2fs -O extents,uninit_bg,dir_index /dev/mapper/VolGroup01-LogVol00 modify /etc/fstab, change the type of / to ext4
reboot
(because fsck say running it on a mounted filesystem can cause filesystem damage, so i decide to reboot to single user mode first. maybe it's a mistake here) try to boot F11 to single user mode, failed
reboot from a SystemRescueCD-1.2.0 LiveCD
run e2fsck -fpDC0 /dev/mapper/VolGroup01-LogVol00 in SystemRescueCD-1.2.0 LiveCD, no error reported
reboot
try to boot F11 normally(multi user mode), but it failed at: EXT3-fs: dm-0: couldn't mount because of unsupported optional features (40).
I tried rescue mode of Fedora-11-i386-netinst.iso after these steps above. The / partition can be found and mounted to /mnt/sysimage correctly. I can read/write files in / partition, and i can even yum new softwares in rescue mode, but it just can't be mounted when booting.

I have vista and opensuse 11.2 on my computer, the problem is i can't open ext3 partitions from vista but i can the other way. I tried Ext2fsd but the linux partition is always in a read only mood even when i change this option. Also, all folders are empty I downloaded the program as admin and compatable with XP SP2.

My System was working fine in the morning..what happened i dont know and i m very confused about this situation
Anybody know how to make an ext3 or 4 partition start up at boot with only the owner and its group having read and write access permissions.I don't want 'others' to have folder access. This is what i have done. / etc/fstab:/dev/sdb5/media/Data ext4 owner 1 2 The folder starts on the boot since it has been allocated a folder as u can see. Next i changed the the ownership and the group ownership of the folder:chown johnny:johnny /media/DataThe problem is that other users can few my partition since 'others' have read access. How do i change that to zero access?

View 5 Replies View Relatedi have a fedora 11 server which can't access the ext4 partitions on lvm logical volumes on a raid array during boot-up. the problem manifested itself after a failed preupgrade to fedora 12; however, i think the attempt at upgrading to fc12 might not have anything to do with the problem, since i last rebooted the server over 250 days ago (sometime soon after the last fedora 11 kernel update). prior to the last reboot, i had successfully rebooted many times (usually after kernel updates) without any problems. i'm pretty sure the fc12 upgrade attempt didn't touch any of the existing files, since it hung on the dependency checking of the fc12 packages. when i try to reboot into my existing fedora 11 installation, though, i get the following screen: (click for full size) a description of the server filesystem (partitions may be different sizes now due to the growing of logical volumes):

except he's talking about fake raid and dmraid, whereas my raid is linux software raid using mdadm. this machine is a headless server which acts as my home file, mail, and web server. it also runs mythtv with four hd tuners. i connect remotely to the server using nx or vnc to run applications directly on the server. i also run an xp professional desktop in a qemu virtual machine on the server for times when i need to use windows. so needless to say, it's a major inconvenience to have the machine down.
