General :: Cannot Copy File Over 16,843,020 Kb On Ext2 Or Ext3 Partition
Aug 26, 2010
i m not able to copy a file over 16 gigs on an EXT2 or EXT3 partition. Is there a way to do this. I even tried to split my iso file too. I splitted my iso file in 4 files then copy them on the ext2 or ext3 partition. But as soon as I was trying to join the files together it never went over 16 gigs. Actually it stops at 16,843,020 kb exactly. is there a limit for those partitions or is there an another way to see my 20gigs iso file in one piece?

I recently installed Linux to run a few Linux based tools on a disk images I have, and I can't seem to copy the disk image over to my ext3 partition.
The particular distibution I'm using is BackTrack 4 r2, which is Ubuntu based. I can't seem to find specifically which version of Ubuntu is being used. The disk image is 108GB. It is currently located on a NTFS partition on a SATA hard drive connected directly to the computer. The ext3 partition is located on a second SATA hard drive connected to the same computer. It has 200GB total. I do not remember exactly how much free space it had but "df -h" showed a lot more than 108GB. The computer has 4GB of RAM and I gave it 8GB of swap space.
At this point it has been running for more than 12 hours. This is far longer than I would expect it to take had I been copying the file under Windows. How ever I do not have much experience with Linux, so if it's supose to take this long please let me know. I am planning on letting it run until I wake up tomorrow.
"cp -v" hasn't been very verbose at all. The only sign I have that indicates the computer is still trying to do something is the HDD light on my chasis that has stayed lit this whole time.

I just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.

I would like to convert my /tmp and /boot partitions from Ext3 to Ext2 on my Arch Linux setup. I don't see any use in having journaling for either partition. I want to make sure that I have the right steps lined up so could someone verify that this is correct (from a live cd):
Code:
#sudo tune2fs -O ^has_journal /dev/sda7
#sudo e2fsck /dev/sda7
#sudo tune2fs -O ^has_journal /dev/sda5
#sudo e2fsck /dev/sda5
I then edit /etc/fstab to reflect these changes (ext3 to ext2 for both lines)
Does it matter what order I do it in (/dev/sda7 is /tmp and /dev/sda5 is /boot).

We are running debian off of an SD card and want to know what's best for /var?
- Plenty of room on 2GB SD card, so do we, make /var as large as possible (everything else is read only) to reduce block overwrites, or do we make /var as small as possible, hopefully reducing the load 'pdflush' places on the 200 Mhz system?
That said, why not ext2? Is there damage that can happen in /var due to insta-crash or power loss that will prevent proper system function? We heard ext4 is more optimized, but ext4 on 2.6.29, not sure.
If we must use a journaled file system for /var, then which is lowest load on system, or "better": jfs, ext3, jffs2 ...

I have ext3 partition mounted on /mnt/shared/ as follows
Code:
Permissions above are of the actual mounted fs.
Goal is to have all files created on the fs
1) to belong to group 'users'
2) to have this groups permissions set to rw (rwx for directories) so that all users who belong to group 'users' have full read/write access to data and everyone else to have only read access.
Now because of setgid bit (s) in group permissions every file created has group 'users' and additionally setgid bit is set for directories. Because every users umask by default (on my system) is set to 0022 all created files will have permissions 644 for ordinary files and 755 for directories.
Net result of above means that users A and B who both belong to group 'users' won't be able to modify files created by the other.
So how can I make files created on the fs to be created always with umask 0002 WITHOUT changing default umask for users that is used elsewhere (like in their home directory) ?

I am planning on dual-booting Windows XP and Ubuntu on a new laptop, and because I have a program that lets me mount an ext2 filesystem on Windows, I was thinking of installing Ubuntu with ext2 instead of ext3. I am concerned, however, that it might open up a security risk for my Ubuntu partition. Would this cause a problem? (In case it's relevant, I use AVG Free antivirus in Windows.)

I use 8GB USB sticks for backup of Ubuntu 10.04. I have had a variety of problems with ext3 format (security tar file not readable, etc) and have reformatted to ext2, so far without a problem.
But - am I missing something by not using ext3 (or even ext4)? Should I be sticking with ext3 and try to resolve the problems - bearing in mind that as the USB stick is my backup I need it to be secure!

I run an upgrade and an update on a lucid lynx beta 2. --- got no problems. but about the filesystems i have some questions because it seems for me that at every system boot the system will run an fsck. somtimes it's shown up, somtimes not. but in /var/log/messages and in syslog
I have always following messages ( occured in beta 2 too ).
But first before i continue - here my disk layout:
And here my filesystem types:
This is my problem because those values are seems to be static ! ( note: this partiton is mounted but not in use ) and last not least: the drive is an external usb scsi disk. but on the other side lucid lynx is running fine on my box.

I have a new Vertex2 Solid State Drive. When I try to install any distributions, formating the drive in EXT3 or EXT4 (or LUKS with EXT3, or EXT4). My hard drive times out during a copy process. (OpenSUSE 11.2 for example would crash after the 2nd file of X11. Debian got ~12% done when it crashed.)
DISTRO'S ATTEMPTED:
Ubuntu 10 - x64
Debian 5 - x64
PCLinuxOS 9 - x32
CentOS 5.4 - x64

I have a question, i accidentally formatted an lvm volume as ext2 after creating it. Then of course, we copied a ton of data to it before I realized it was ext2. (I guess ext2 was the default when using mkfs without a -t) Anyway - can I just use tune2fs -j on the LVM just like I would a /dev/sdx device?

I am student of MCS and working on final project. I am the user of windows xp. I am new in Linux. I am working on a project that titles "Hard disk data Recovery of ext2 and ext3 in linux". In windows, including dos.h and bios.h header files in program of c language I can send interrupt to bios and access most of the devices like parallel port, hard disks etc. But problem is that there is no bios.h and dos.h files in gcc. Now how can I access my hard drive using c program. How can I call int13h interrupt in linux or there is any other function in the linux to access the hard disk. In fact I want to access sectors of my hard disk using c language program. How can I do it?

I had to install a new disk drive in my PC a week ago because the old drive died. The new drive is a 160 gig drive. First I installed Win XP with S/P 3 and everything was fine. Then I installed Ubuntu 8.04 and the troubles began. Ubuntu resized the Windows partition down to 8.81 gig and used the other 137.44 gig for Ubuntu. When I booted into Windows I started getting nasty little messages about "not enough disk space". SOOoooo....... I booted using the Ubuntu install CD and ran "sudo gparted" in a terminal window. I tried to resize the ext2 partition but got an unknown error.
Then I ran fixmbr in Windows to get rid of grub. Then I tried running gparted again to delete the ext2 partition. Got an error that said "can't delete the partition because it's mounted". So I tried to unmount the partition but got a message that the command "unmount" could not be found. After that I installed Partition Magic in Windows and tried that. It sees the ext2 partition but says it's unsupported when I try to delete or resize it.
I ran fdisk but it doesn't see the Linux partitions either, so I can't delete them in that program. I finally tried to format the disk but now I have a 9 gig drive with nothing on it. How do I get those Linux partitions off the drive so I will have a 160 gig drive that I can start over with? I've spent 6 days this week reinstalling XP and all of my programs, and now everything is gone because Ubuntu decided to be a disk hog.

During the file system check of an ext3 partition at boot I get the following output:
The super-block could not be read or does not describe a correct ext2 filesystem. If the device is still valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate super-block:
I'm then forced to login in as root and given the following prompt:
I'm reluctant to do as advised by the output and run e2fsck -b because it is not an ext2 filesystem.
Although I can still enter runlevel 5, it doesn't seem to recognise mouse and keyboard input in KDE so my system is effectively redundant at the mo. For this reason any short term workarounds are welcome, but a fix is needed. This problem is part of a longer saga to do with recovering a Windows Vista installation which started failing to boot. I have used both Vista and SUSE tools to try and recover my bootloader to no avail, and this has been the result. If more detail about this is needed please ask and I can explain what I have done.

I was installing windows vista on my computer, so I backed up everything to a external drive which was formatted with ext2. I then proceeded to install windows vista. When I got to the partition section I tried installing windows vista to my raid 0. When it didn't work I decided that I would delete all my existing partitions and create a new one. Well in my haste I accidentally deleted my ext2 partition from my backup drive that was still connected. As soon as I realized what I had done I shutdown the windows install and disconnected my external drive. This is the current state of my drive from parted:
Model: WD 15EADS External (scsi)
Disk /dev/sdb: 1500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
I know that the drive only had one partition before and that it took up the entire disk and it was ext2 (maybe ext3).

This might be a longshot but i used to use the 4 bay NAS here Which formated the HDD JBOD array to EXT2 , Anyway i want to move to an 8 bay DAS now but i cant find an application to convert the partitions .
Partition magic says the partitions are unformatted and the partition id is set to linux raid auto . Is there any way to convert this partition to vanilla EXT2 so i can use partition magic on it ? Its a 4TB array so copying isnt possible.

I need to mount my ext2 partition with write permissions for an average user. Right now, I can only write to the volume using sudo or the root account.
/etc/fstab:
Code:
# Filesystem: Mountpoint: Type: Options: Dump: FSCK:
/dev/sda1 / ext4 defaults 1 1
/dev/sda5 swap swap defaults 0 0
[code]....
can't add the options uid=500,gid=500 to the ext2 volume because it says "bad option" I have 1 question. If you have a volume listed in /etc/fstab, and you try to mount it with different options than the ones listed in fstab, will it mount with the new options, or the fstab options?(e.x. if I try to mount /dev/sda6 with: mount-o auto,user,exec,rw,async. Will it mount with async or sync?)

I work with a Debian Squeeze on my laptop and I have a 160GB external hard disk. My hard disk was formatted FAT32, but I decided to format it using ext2. I formatted it using fdisk from command line and everything went well. Unfortunately, when I mount my hard drive(which is auto-mounted from Debian) it has got root both as owner and group. Then I can't write to it because I have no permission to do that. Is there a setting to create an ext2 partition which has as owner the logged system user in order to have right permission every time.

A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.

I got a new hard disk for my laptop and I want to move my Gentoo installation from old HDD to new.
Most simple guides recommend use of dd to copy the whole partition byte by byte.
I'm moving to the new drive because I don't have enough space on the old drive, so I don't want to simply clone the partition. Instead I need the destination partition to be bigger. Would dd work well in that case?
Assuming that I use same partition types on the new drive, would I be able to use simple cp with appropriate settings?

How to copy a Read-Only file in Linux and make the copy writable with a single cp command in Linux (Ubuntu 10.04)? The --no-preserve and --preserve seemed to be good candidates, except that they should "and" the mode flags, while what I am looking for is something that will "or" them (add +w mode).
More details: I have to import a repository from GIT to Perforce. I want that all Perforce depot files are Read-Only (that is how Perforce was designed), while all other files that were derived/copied from depot files are writable. Currently if a Makefile tries to copy a Read-Only file then the derived file will also be Read-only. This leads to build-errors when cp tries to overwrite Read-Only file second time. Of course the --force is a workaround here but then the derived file is also Read-Only. Also I do not want to mess with "chmod" after each "cp" command - I will do that only as the last resort.

i TOTALLY ****ed up my windows bootmgr, and, in some way, the linux partition too. I'd like to format the windows partition, but as all my info stays intact I'd like to conserve it that way. The only way I can think of, is to make a new ext2 partition on the same HDD y have windows ( I only have one HDD, so... ) and save the information there . Wich is the correct way to do so, without losing all my software and/or information??
Other details:
* Rright now, i don't have ubuntu installed on my pc ( I'm using a live cd ).
* I'm using ( or was ) win 7.
* The only partitions on my HDD is an ntfs ( 60 GB ) and an unallocated ( 240 GB )
