Fedora :: F11 Not Seeing CentOS Data On Shared Partition?
Sep 3, 2009
I created an ext3 partition to be able to share data or files between CentOS 5.3 and F11 (and possibly other distros...) on /dev/sda5. I created the folder under /mnt and edited fstab and it's mounting ok and it lets me write to the drive.
But it's only seeing the files I wrote to it in F11, not the files or folders I created in CentOS; not even the text files created in gedit. I read some messages on here, and made myself the owner of the folder (data2share) and rebooted and it's still not seeing the files.
Might it be because F11 is using ext4 and CentOS is using ext3 ?? To test that theory, I started my external usb drive that's also formatted ext3 and it's seeing those files just fine. So I'm stumped.
Here's the output from /sbin/fdisk -
Code:
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I am installing a custom 8.04 live disk (basically, a mirror of my whole system with user data intact, sans all non-OS files) from a USB key with remastersys for the .iso creation, and UNetbootin for the bootable USB on a brand new 120GB PATA WD HDD. Both do nicely so far, so I have a working livedisk to use until I need to install Ubuntu to the drive.
I had a pure linux box, but I need to add XP with dual booting now- I have to use Autodesk Inventor 2010 software for my college class on my laptop, so I don't drive 30 miles to use the 1 computer lab equipped with that software. I'm not new to Linux, but I am new to more in-depth partitioning. I've taken the lead and looked into things- read this good guide, among others:
HTML Code: http://www.psychocats.net/ubuntu/partitioning and noticed that there is a way to more deftly use partitions so that personal files can be shared access and write between Windows and Linux partitions- with this: HTML Code: http://www.fs-driver.org/ Ubuntu is still my main OS, but being able to access all my media/data files between the 2 systems would be nice. Problem is, until now, I've put everything on a single partition because I didn't know better. Now I do, but am a bit confused with all the guides as to what's most efficient, especially in my case where full RAM speed is crucial to running a single program.
Here's what I know I need to do: 1. The Windows XP install I know needs from 20-30GB for Inventor 2010 LT to work well. I don't need anything else in XP spacewise- it's just being added for Inventor. 2. I'd like to create a separate /home partition for Ubuntu this time to save my user data, making future upgrades much more painless (I will be getting Lucid soon). How that works when upgrading, though, I don't know yet..
3. I'd like both OSes to share all my personal files (docs, pics, music, Inventor design files) if it is an efficient choice that works without problems.
4. Finally, because 2GB is minimum for Inventor to run decently, I need to maximize the speed of my RAM for it- from my reading, these so-called "swap" partitions can somehow be added for buffering this- people seem to sugguest the swap be half the size of the RAM for fastest speed, and some say add separate /usr or other partitions. I'm not clear on what would be most efficient for me.
I have limited HDD space- because of my laptop's BIOS, this single 120GB drive is the biggest I can get on my laptop, so efficient partitioning would make a huge difference for me. Before this, a 60GB HDD was in this. I'd like to see some added space for my data storage, but still keep things as fast as possible for Inventor when I use it, and Ubuntu.
I'd like the final layout to have a Windows partition (will start out as XP and will become Win7 when I can afford yet another copy), a partition for Ubuntu, and a shared Data partition that I can use for all my files between both OSs. I think this should be fairly straight forward with Linux on a Primary partition with / and swap. Only thing is, from what I've read (and yes I know this is a bit old school) it might be a good idea to put in a /Home partition so that I can reinstall new upgrades and maintain settings. But I don't want to max out my 4 primary partitions so I can use a 4th partition as a kind of sandbox for OS testing without using VirtualBox all the time.
This leaves me in need of some advice, I've never used Fdisk and I was planning on just using the Ubuntu installer to do all of this, but I don't know if I can create /Home as a logical partition in the main Ubuntu partition and still have the benefit of being able to reformat /root without losing /Home. I might have just confused myself, because no matter how many guides and How Tos I read I still don't really get extended partitions, I understand logical vs. primary but extended is...confusing. I need the Ubuntu partition to be bootable, so it needs to be a primary partition...I think. Unless I can have: /boot, /, swap, and /Home...
Also, if Ubuntu can read NTFS, and Win7 can read Ext3, what should a do with /Data? Or should I just go with FAT32 and be done with it. (It's a big HDD btw, 640 GB, so /Data will be fairly large)
I need to mount a bsd/386 partition on my hard drive to recover data. I am running the latest CentOS 5.3, downloaded and installed in the last week.My searches have turned up a mount command, that does not work.
[root@new-host-2 ~]# mount -t ufs -o fstype=444bsd /dev/sda3 /mnt/bsd mount: unknown filesystem type 'ufs' [root@new-host-2 ~]# mount /dev/sda3 /mnt/bsd
[code]...
So, is there a patch to get mount -t ufs working?is there a patch to get bsd/386 filesystem type? have not build a kernel before, so I would like to avoid that, but I will attempt it if I have no other options.
I'm trying to achieve my dream (but indeed not perfect) boot scenario: dual-boot OpenSUSE and Fedora with shared /boot, /home and SWAP partitions. First I installed OpenSUSE (sda3 on my layout below) with separate /boot (sda2), /home (sda5, encrypted) and SWAP (sda6), next I installed Fedora on /dev/sda1, and pointed it to mount sda2, sda5, sda6 with respective mount points, without formatting. I proceeded with the installation without installing new GRUB bootloader (overwriting an existing one).
It was successfull and now I'm back in OpenSuSE trying to edit menu.lst file (under /boot/grub) to make GRUB boot Fedora.
I attached a copy of menu.lst I cooked up for now. OK, it's a mess. Life would be allot easier if I didn't have a separate /boot partition, as I could just chainload, but it's no longer possible (or is it?). May be I needed to specify the resume device or problem is in initrd? below are the contents of /boot:
I am using Centos 5.2, and I installed all of the available gnome and gnome development libraries available via the "add software" menu item. Still, when running some programs, I get the following error message:
"error while loading shared libraries: libzvt.so.2: cannot open shared object file: No such file or directory"
If I understood it correctly, libzvt.so.2 is part of some gnome libs... where to find and how to install them?
In the process of preupgrading to FC12. Towards the end of the process I get a warning that my /boot partition isn't big enough (12 recommends minimum of 300Mb).
Is there a tool I can use to resize my existing partitions WITHOUT data loss? I've been using gparted up to now for sorting partition stuff, does that maintain data when resizing (assuming I run from a boot CD or USB rather than a running system)?
By mistake I formatted an ext3 partition on my external hard-drive. Now it has turned into a vfat filesystem. Is their any chance of recovering the lost data?
During a recent request to install fedora 11, I ran into an interesting problem. It seems that between fedora10 and fedora11, the developers switched from fdisk, to parted for creating the initial pre-mke2fs partition table creation.
It looks like the implementation of this is broken, as it's writing the partition table with overlapping cylinder boundaries. While this can sometimes be ignored, it can in certain cases cause significant data corruption.
On an installation I took it through, using the latest installation media, in both manual & automatic partition creation, the layout looked like this:
The last two partitions turn out fine, for some reason. However, those two partitions should not have overlapping cylinders. After my very first installation, the system was completely unbootable, and not even fsck wouldn't rescue it. If this is possible, then that means that a system that's been online for months or even years could simply drop out of functionality simply due to a byte or two of system-critical data falling on that last cylinder. Considering that a lot of the time kernel data ends up on /dev/sda1 (commonly the /boot partition), this is something that should not be ignored.
I have a home directory which is mounted on the LVM partition,How can i reduce the size of LVM partiotion without loosing the data on home directory...whenever i use lvreduce command it show me a warning mesg that the whole data will be lost...reducing the size of LVM partition without loosing my home directory data.
I'm actually not a Linux newbie, but I'm DEFINITELY no expert either... I'm trying to copy all my data(approx 50 GB) from a usb drive(western digital 250GB) with ntfs partition in one go... The problem is that it only fails for big transfers... works fine for smaller transfers like 1Gigs or less... I have just one internal hdd partitioned into two ext3 partitions.. so I have sda1(Primary.. mount pt /), sda2(swap) and sda3(mount pt /piyush)... The usb drive comes up as sdb(sdb1).. just has one ntfs partition... I've also installed the ntf-3g drivers.... but doesn't seem to work... I've also noticed that when the machine hangs and I try to shut down, it fails and I get a message again again... (sdb1- no sense detected) or something like this... don't remember the exact message... will post the exact one if no one is able to figure out what's wrong...
I have written an application which has more than 6 threads.Two threads share a common linked list. Out of two threads one thread reads the linked list node and other thread writes to linked list node.I am using pthread_mutex_lock() API to achieve synchronisation between having access to common linked list. The problem is the first thread which reads the linked list accesses the mutex faster making other thread to starve.
I want both the thread to have an access to mutex. It should not happen that always first thread locks, releases and relocks it. The first thread almost require to access the link list every 5 msec which is causing second thread not to gain the mutex.How should I fix this? For information, I am running this application on PXA270 ARM platform.
i have installed nfs server on my redhat machine.when i want to mount shared data from client(suse)machine the following error occur. "mount.nfs: mount to NFS server '10.3.31.146:/home/usbtest' failed: System Error: No route to host" both machines ping each other successfully.
I have just spent dome time using gparted to sort out my partitions. I have a vista partition, a fedora one and a big chunk of unallocated space I wish to use as my data drive.
I want to move my ~ folder to the new partition and have windows/vista access the folder and write to the Documents, Downloads folders etc.
What is the best format to use?
Also I plan to start backing up my partitions to a server, for instance using g4l to save a linux image (maby a windose one too). Is there any benifit in keeping all the hidden files (ones starting with period '.') i.e moving the whole ~ folder or would I be best off leaving the ~ dir and moving the folders I know i use such as ~/Downloads, ~/Documents etc?
And how should i preform the move of all these files? 'mv'? do i need to add any special options?
I just installed F13 x86_64 on a system that used to be running Windows 7.
The boot drive is a SATA drive attached to the motherboard which is working fine.
However, my data drive is an NTFS partition filling a 3.6TB SATA raid.
It's GPT--Gparted sees 3 unknown partitions, and gdisk shows:
Code:
How do I mount this in Fedora 13? I had intended to shrink the NTFS partition so that I can create an ext4 partition to move the data to. Will this be possible?
I've got a LOT of valuable data on this drive, and nothing else big enough to store it.
We want to fix our data folders structre in Samba, for example our folders would be like as Data/Group A/2010 /A.We want all our users can work only in folder A and no one can create any files in data, GroupA, 2010 folders. Similarly no one can delete these basic folders. However users can create further folders in A as required.
I've been using Ubuntu 10.10 for just under a week. Recently, a partition called 'Data' has disappeared, and all my music and documents along with it. The folder is not to be seen in Places or on my desktop. My only way of finding it is to go to terminal. But when I try to open it there I get an error saying I don't have permission to read it. In Puppy Linux and SliTaz I can easily find the partition and read it. What should I do to bring it back in Ubuntu?
I usually repartition a disk by backing up, deleting the partitions, formatting them and repartition. I just did a 200 gig backup (so i am safe) and i want to join 2 (ext3) partition together, sdb1 (data4) and sdb5 (data5) into one big partition. Is there a way to do it without scraping the data in sdb5 (data5). It would save me from rewriting the data back to that new partition (200 gig is time consuming).
I have a separate ext4 partition which contains all my data (music, movies, etc). When I delete files from this partition it is very slow because it copies files from my data partition to the Trash folder in my home partition. How can I avoid this? Can't the trash be configured so that it uses a trash folder in each partition instead of copying files to another partition (which is slow).
I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.
I've created quite a predicament with my desktop installation and would prefer to be able to salvage it instead of having to reformat/re-install Ubuntu.
Quite a lot happened and here's my best recollection:
- My Ubuntu installation stopped working and I could not get the desktop to load.
- I backup up my entire home directory by creating a zip file along with other small zip files. I used Alt + Del + F1 to get the CLI to do this.
- I then did different things trying to get the desktop to load.
- I did a apt-get upgrade, to try and get it to work; this was not sucessful.
- Working through several dependency issues I finally got sudo apt-get ubuntu-desktop upgrade to work, but it did not finish completely. I started to get out of memory errors. I am assuming this was because too much hard drive space was taken up by the zip files I had created
-I could not boot and do anything properly after that. Every attempt to modify the filesystem (to free up space) results in an error "Read Only File System". The root file system was not being mounted and I would see root@none on the CL
- Looking on the boot loader I now have Ubuntu 9.10 2.6.24-generic installed
- I burnt a new installation of Ubuntu 10.4 LTS
- Using Live CD I tried to see if I could free up some space and get the system back to more stable state,
However this was NOT sucessful. I tried to mount my drive by sudo mount -t ext3 <dev> <dir> but I keep getting the following error: error while loading shared libraries: /lib/libsepol.so.1: cannot read file data: Input/output error
When i work in Ubuntu on a dual boot system with a shared NTFS data-partition where Windows is hibernated, and then reboot and continue working in Windows from the hibernated sesion, strange things happen. Files disappear, files that i worked on suddenly have the content of another file.
Our application uses a dynamically loaded shared object library (codec library) to compress and decompress audio streams.
There happens to be several static and global variables in this shared object library. Hence it is not possible to process two interleaved unrelated media streams using this shared object codec library because each stream corrupts/changes the contents of these static/global variables.
Is there a way through which a context save (save contents of data segment of shared object) and a context load (load previously saved contents of data segment of shared object)operation can be performed on the shared object library. This way the context for each media stream can be saved and loaded before and after processing the "other" media stream respectively.
i already reserved the space for the partition, from what i have read so far, it has to be FAT32 or NTFS. also my major question is how i would be able to point both OS to save my files to the 3rd partition i am creating for sharing. cos in my experience, windows likes to store files in its home partition without even giving u an option to see other partitions in ur system, ubuntu at leastb allows me see the other partitions on the drive.
I am dual booting windows 7 and ubuntu 10.04 using grub. I am using a 1tb samsung hard drive. Ubuntu has 750gb and windows has 250gb. I want 500gb of my HD to be FAT32 so I can put all of my music, pictures, and videos on it. I don't have more than 100gb used on either partition.
I have done quite a bit of searching and browsing, but I can't find a good step by step guide to do this. I am guessing I need to figure out how to use fdisk?
I was wondering if theres a way to create a folder that would be accessible when I boot with windows or ubuntu? Is there some shared location I can place this folder?
Just a general question: If I have /home on a separate partition, is it possible to mount that /home partition on multiple distributions (Ubuntu, SuSE for example) on the same PC?
I dual boot, in the process of installing Windows 7 & Fedora 13 on a new drive. Back in the day when it was risky for the newbie to read/write NTFS, I created a "shared" FAT32 partition. Even though the later Fedoras could read/write NTFS fresh out of the box, I have kept the "shared" partition for my important files (email, documents, digital camera pics).
Now that I'm installing Win7 and Fedora 13 on a new hard drive and I'm partitioning my disk, I'm scratching my head trying to decide how I should format this partition. I was considering the FAT32 again, but I'd like 50GB, not just 32. At the same time, I'm thinking of making the size sacrifice because, and maybe this is just carryover from the olden days and groundless, I have an irrational worry about using NTFS for my most important files.Maybe someone could assuage my fears. Is it just as safe, at this point, for files to be on a NTFS partition and run under Fedora as they are under FAT32?
I used to have three partitions: Win7, Fedora 12 and a NTFS-Storage-Partition.Now I had to reinstall Win7, it doesn't see any files on the storage partition;Windows shows the whole rest of the disk including the linux partition as one drive with 7gb of 80gb free, I can also open it but then there is nothing in it.Linux is still working and everything on the storage partition is still there and accessible in linux.any suggestions? do i have to tell windows the partitions or does it have to do a scan or something?
Installed fedora/configued samba, shared printer and i am not able to access shared printer from any of the fedora machine. I am able to access the printer /shared folder from windows machine. I dont know the process of cups installation.
