General :: Sharing An Ext3/ext4 Partition On External Drive?
Aug 30, 2011
is there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?This would mean that I need to have root privileges on every machine... which I may not have in some cases.I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive.
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
Recently my laptop broke down and wont start up. I'm currently trying to recover my files to my mac with an IDE to USB cable. It recognized my windows partition fine and I was able to get all my files off of that, but the majority of my stuff is on the ext4 partition that I have on it. Does anyone know how to access the ubuntu partition of this hard drive from my mac?
I am wondering if any of you technical guys would be willing to format my Western Digital external USB 1.5 TB Hard Drive to Linux EXT3. I am naturally happy to pay for your time and trouble and for postage. The WD drive is for storing video footage and will be connected to my Humax Freesat HD Digital TV Box(not a computer), and the Humax Box will only record high deffination programmes in EXT3 format. I've tried to do the job myself with my PC, but have failed to change my system to format in Linux.
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 have an Iomega External Hard Drive 1TB. Problem: Unable to write to Ext3 Partition. How I got here: Started off with going into windows and shrinking it's current NTFS partition down by 50GB. Then used an Ubuntu LiveCD to gain access to GParted and with that 50GB free I formatted it with an Ext3 system. It does this no problems. I then can't write anything to this partition? I've tried doing "chmod 777 /dev/sdb2" but it says Operation not Permitted.
EDIT: Need to be able to use it on YDL 6.2 on my PS3, YDL doesn't have NTFS write support and I want to transfer files larger than 4GB rendering Fat32 useless. No I'm not able to re-size or compress this large file.
I'm trying to format a 500 GB external drive with gparted in ubuntu 10.10 (I searched & didn't see this issue in the forum). I set up and formatted two partitions, one for fat32, and the other with ext3, which appears to format ok, but I can't use it. Both partitions show up and appear to mount, but the ext3 partition won't accept activity (make new folder, copy in files), while the fat32 partition works fine. Both partitions show up ok when I query in terminal "sudo fdisk -l"
I have an external USB drive formatted to EXT4.I can browse all folders without a problem. However, I can only see files under (I'm guessing this value) 400mb. Where a folder contains file(s) over that size, I cannot see the larger files. I am able to see smaller files in the same folder (eg jpgs).Looking at the properties of the drive, it says 584GB used. However, the "Contents" are only shown as 89GB and then a message saying "some contents unreadable".
I wanted to make a clone of my drive, so I tried the ole sudo dd if=/dev/sda1 of=/dev/sdg1 trick, but first I formatted the drive to the Ext4 format. I wish I would have understood that format a little more before I decided to format it that way. Now I can't access my drive at all. I read almost everything on the net about manually mounting it, but almost everything was in Fat, NTFS, or Ext3/2 format. I even read the Ubuntu documentation. I don't know if it's because my drive is in Ext4 format, or if I'm just not doing something right.
As you can see in the following picture, it recognizes the drive, yet I am unable to mount it. I am trying to access the 160 GB drive. I even tried to see if Windows would recognize it. No go. Today while lurking in the Ubuntu Forums I found a way to make a live .iso of my system (which I think is awesome). So now I want to reformat my drive and use it as storage once again. I think I will restore it to NTFS. I thought that the Ext4 format would work better in Linux (which I was wrong), but now I need Windows to recognize it as well, and it needs to be able to store files bigger than 4 GB (unless you have a suggestion on what to format it as).
I have a little ODROID C1+ ARM box with Debian Jesse installed on a SD card. I am trying to share an entire external USB NTFS drive to all clients (Windows 7, Android) on my network. I had this working until a few days ago when I reflashed an updated distro. Now I can't remember what black magic was involved. iptables is not installed and no firewall is active.I have installed Samba and Caja-share. I have edited the fstab
with the understanding that this would allow permissions to be assigned and saved for NTFS partitions. I then used chmod to assign everything on the drive to nobody:nogroup as I recalled this was necessary from when I last got it to work.SMB.config is currently set as
Code: Select allworkgroup = *edited* [Seagate 4TB] path = "/media/odroid/Seagate 4TB" writable = yes force user = nobody
with no other changes. The folder /media/odroid/Seagate 4TB has been created. I have right-clicked this folder and shared with Caja-share
Code: Select all[x] Share this folder Share name: Seagate 4TB [x] Allow others to create and delete files in this folder [x] Guest access (for people without a user account)
but so far all I get in Windows when I try to access the share is a prompt for credentials, which is what I want to avoid.
Tuesday night I wanted to make a backup of my Ubuntu ext4 partition via Clonezilla so I configured that an image had to be made and it would be saved on the NTFS external disk. But it said it needed 23 hours to create a 5gb backup, so I resetted my computer as this took too long. But after this, Ubuntu nor Windows recognized my drive.
I called Seagate and they told me after troubleshooting 30 minutes, that there is no option of fixing the drive and I had to send it to RMA. What could be wrong? Clonezilla works via a bootable ISO on Debian. The disk drive is still spinning. I already rebooted the external drive, but it's not working. In Linux the disk is no longer mounted and cannot be mounted:
Code: brw-rw---- 1 root disk 8, 16 2010-03-12 00:50 /dev/sdb brw-rw---- 1 root disk 8, 32 2010-03-12 00:50 /dev/sdc brw-rw---- 1 root disk 8, 48 2010-03-12 00:50 /dev/sdd brw-rw---- 1 root disk 8, 64 2010-03-12 00:50 /dev/sde
What could have happened? Would the data still be accessible on the internal drive? Did I just loose 1.5TB data that was stored on the external disk?
I have installed ubuntu to my pc. i made 3 partitions. one for system, one for data and one for swap. two of them were ext4. after some time i have reinstalled ubuntu again. but this time i didn't put to format the second partition, but just mount it using ext4. after that i cannot open my files. checked with gparted shows that 2GB used, but with df 188MB. and in properties writes ext3/ext4 filesystem. i used chown, chgrp but didn't help. please help, these data are ver important. i cannot lose them.
How can I format a USB hard drive to ext3/ext4 or whatever file format and have full permission to read, write and execute all files afterwards? When using the command line (as ROOT of course) mkfs.ext3 /dev/sdb? Restricts the rights to ROOT as does the procedure gParted. The man mkfs did not help much. Configuring the fstab- file is a bit of a hassle, so it would be nice, if there was an option to set the permissions "correctly" right from the beginning. Setting Ubuntu (I'm using Ubuntu 9.10) up, so that it mounts USB devices not as ROOT as default but giving all users all permissions seems to be really complicated, as a guy from my local LUG told me.
i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.
Computer hardware is not my bag. I accidentally installed ubuntu on external F drive, thinking it was C drive, unaware that ubuntu installs on drive with most available space. Installation involved partitioning the drive in about half. So, before I install it on C drive, I want to restore my F drive. I deleted partition using XP Disk Management tool and tried to use gParted on Parted Magic live boot cd to resize remaining partition that contains my data. But it doesn't seem able to expand the good partition to reclaim the 'unallocated' space. How do I accomplish this? Must I backup and reformat?
I have a problem with sharing files from external harddrive. If I create a share from my ubuntu home folder, I can access to it from my Windows 7 laptop. I also see shares created from external drive, but windows says I dont have permission to access in there.
I was in the process of installing Ubuntu 11.10, but got stuck choosing which file system to use. ext3 and ext4; which is better for a personal desktop? If ext4 is better, will it work well on my old PC (bought 3 years ago), or perhaps ext4 is not actually compatible with an old hard disk?
I have just purchased a 2TB drive for my server and I was trying to get an idea of the differences between these file systems or other file systems out there. What is the amount of space after formatting for ext4, ext3, and ntfs?
iMac (no internal drive/dead) --------- (Firewire) ------- [[MAC OS X]] | | |[code]...
I routinely use the firewire drive to boot MAC OS X.However, I would like to boot from the linux partition of the USB drive. This linux partition had linux installed on it from a live cd, and during that process, I told the installer to install GRUB on the usb drive (which happened to be /dev/sdd).My question is, how do I get this disk to show up during the iMac option-boot? Currently, only the firewire MAC OS X option shows up. I have read about rEFIT, but that appears to install it to the Mac OS X disk (would that still work?)...Also mentioned was installing rEFIT to the internal EFI system partition, but I don't know if that is wise.
I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?
Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?
I am keen to start using Ubuntu and have installed it on one of 4 partitions on my new 1 TB external HD. I got to the reboot stage where I was expecting a new boot screen where I could decide to use either XP or Ubuntu. But there is no mention of Ubuntu just XP and the volume I installed Ubuntu on has disappeared. I can find the other 3 volumes on My Computer.
I installed Fedora 15 5 days ago after using debian-based distros for a few years, and until now I've had the habit of sharing many files (mostly multimedia) on my home network, except since I'm the only one using Linux, I have to do it using Samba.In Ubuntu, Xubuntu and Linux Mint, this worked like a charm.
Two things have changed this week: I switched to Fedora 15 like I said before, and I bought a new USB external HDD. I previously used a 500 GB Western Digital, and changed for a 1.5 TB SAMSUNG which is linked to my station via USB. The drive works well and I cp'd the 450 gigs of the ancient drive within the new one without a problem.
Ever since I managed to set up fedora and GNOME 3 as I would like it, I've been trying to setup the network sharing via Samba, and that's a genuine 4-day long headache now.Thing is, yesterday, it worked. After setting everything right, creating an automount of the external HDD in a maybe-too-much permissive folder, allowing Samba through the firewall, getting to know that buddy called SELinux I had never met before and which I struggled to tame ; after setting everything up, it worked seamlessly, I streamed music from the Windows PCs of my network and began watching a film.
Except I had a problem which had nothing to do with Linux: letting the USB drive plugged in on startup prevented the BIOS phase from going well, and my station was stuck on my motherboard splashscreen. To fix this, I had to disable the USB Legacy in my BIOS. Did the trick. Yesterday night, I rebooted like that, and everything was fine.This morning, Fedora wouldn't boot. Since the new BIOS parameters didn't switch the drive on on startup, fstab was trying to mount a drive which wasn't there, and thus crashed, switching to emergency mode.Had to remove the ftsab line concerning the USB drive for Fedora to boot again.
Alrite, that's fixed, I thought ; I just changed the fstab options adding noauto,user, etc. and I thought it would be ok, but it ain't.It's now been 3 hours without me finding any clue as to how to get this working.
IMO, the problem comes from the fact that Samba is missing the right to access the drive. Samba seems to be OK: from the Windows station I can see my Linux station on the network map, I can access it entering the Smbuser I created for this, and the "ext-hdd" dir is present (that's the alias I used in the Samba config files), but when I try to access it, Windows says it can't access it.
I'll try to add as many pieces of information as possible that might be useful:
Code: [norfen@norfens-station ~]$ getsebool -a | grep samba samba_create_home_dirs --> on samba_domain_controller --> on samba_enable_home_dirs --> off code....
when I try to share files off of my external hard drive over my network; it says it is shared on my ubuntu machine but when I try to access the file on my windows machine it says I do not have permission.
I have an external USB hard drive at /dev/sdb1 (NTFS)
2 users: johnny, audio
for some reason this drive is mounted at /media/TREKSTOR_ with johnny as the owner. I can't seem to chown the drive to audio. If I unmount the device, and remount it, the owner is set to johnny again. I need to access this drive from the audio account.It's a 1TB drive, so I wouldn't be able to reformat it to EXT3 easily as it's almost 60% full.
How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?
I had a 500gb hard drive that I wanted to use on my Ubuntu system as a media storage drive. The drive originally had two partitions on it,one was a Dell Recovery partition and the other was a Windows Vista partition. Using the Palimpsest Drive Utility that comes with Ubuntu, I deleted both partitions,created a Ext3 partition using 100% of the space and copied my data to the drive. After I finally got fstab to load the drive, I found another problem. First of all, when Grub loads, two options it offers are:
Windows Vista (loader) on sdc1 Windows Vista (loader) on sdc3
Aside from that, 100% of the drive is not being used by the Ext3 partition.It is showing 434.6gb available on the drive. Fdisk is not showing any other partitions on this drive, so A) why are the Windows loader options showing up under Grub and B) why do I not have 500gb available?Here is a copy of the output fdisk -l:
Code: Disk /dev/sda: 80.0 GB, 80000000000 bytes 255 heads, 63 sectors/track, 9726 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes[code]....
I have a flash drive that I use to sync my work- and home-computers. Rsync has occasional issues syncing between FAT32 (which I use on my flash drive b/c it's universal) and EXT3.
I decided to create an EXT3 partition on the flash drive in an attempt to alleviate the rsync woes. My problem is that when I create the partition using GParted, Ubuntu auto-mounts it with Root as the owner. I had GParted check the drive, and it found no errors to repair.
One other weird thing is that the EXT3 partition shows 84.7MB being used immediately after creating the new partition.
The FAT32 partition mounts fine, is read/write, and only shows 4KB used after the new partition scheme.
I tried doing new partitions a number of times, with EXT2, EXT3, and EXT4 just to see if that mysteriously made a difference. Each time that partition would mount w/ Root as owner.
