CentOS 5 :: Can't Write To NTFS: Volume Is Read-only?
Aug 22, 2010
I installed CentOS 5.5 32-bit with Gnome and want to use it as a file server. The volume I wish to share is a 1.5TB NTFS partition stored on a USB drive. I installed "ntfsprogs" and "fuse-ntfs-3g" to get NTFS support. However, I only have read access to the volume.
How can I fix this and get Read+Write to the NTFS drive?
After installing the "fuse" and "fuse-ntfs-3g" packages, my ntfs formatted thumb drive mounts read only, as follows:# mount.../dev/sdb1 on /media/disk type fuseblk (rw,noexec,nosuid,nodev,allow_other,default_permissions,blksize=4096)
As part of my testing, I need to find a tool that will write/read IO to a volume. I need it to fill the volume and then read and verify that the write was successful. hroughput stats would be a plus, but right now, IO verification is a must.I need the volume to write, read, verify, then repeat until the volume is full.Can anyone point me to a free tool that can manage this?
I have installed Ubuntu 11.04 64 bit desktop version on ext4 partition without swap. I have maximus iv extreme motherboard with 8 Gbytes RAM. Using 3 internal ntfs formatted hard drives and 3 external ntfs usb 2.0 hard drives.When I am trying to copy or move files FROM or TO any ntfs partiton it is 90 percent chance it is going to freeze.For copy/moving files I am using krusader run as ROOT or as user without root privilege or Nautilus as user without root privilege. It wasn't possible to switch to another terminal - it simply does not react on keyboard or mouse input and only hard reset is possible (scares me because of ntfs disks)From this point of view I have suspicious on ntfs driver but:I am completely beginner in linux and I am looking for help to navigate me how to investigate to find what is causing the problem eventually to solve it?
According to my experience it seems to does not matter if hard disk is internal or external connected through SATA II or SATA III or USB 2.0. I have tried to manipulate with ntfspartitions through the vmware or virualbox or truecrypt software or just do a simplecopy/move files - it have has always the same results - freeze. There is not possible to say how long it is going to work properly and when it is going to freeze - sometimes it's working hour, sometimes it's working couple of seconds - no matter if it is read or write operation/s within ntfs partition.
I have a Windows 2003 server with fiber attached volumes (NTFS) that I would like to mount readonly on a linux system to back it up to tape. The fiber device will allow me to present the volume R/W to one host and R/O to another, however, the R/O system doesn't see any of the changes made by the R/W server. In other words, how can I make a readonly volume refresh, scan for changes, or update without un/re-mounting it?
Is the "mount -o --bind" option what I want? From the MAN is doesn't seem right... the option "sync" seems slightly more promising but I think I'm just grasping at straws here. The best I have come up with is a cron job to unmount then mount the volume periodically.
I've installed two Linux distributions in my PC, Fedora12 and CentOS 5.5, and also Windows in a ntfs partition. I can operate windows partition in Fedora easily, however, I cannot find the windows partition in CentOS, furthermore, in CentOS all mobile hard drive that formatted as NTFS cannot be mounted.
I am new to Centos and linux in general. I have just got myself a Dell 1950 server with 2x 1T SATA2 hard disks in it. now the server comes with a PERC5i Raid card with 512Mb. Well I put these in raid 0 and the raid card initilzed the disks to 128 writeback and read ahead. When I loaded centos it did not recognize the dell layout so therefore wanted to initalize it again, so I done this as it wanted. Now I created a 80gb boot and o/s partition and a 100gb swap the rest was created into LVM space to run solus vmwear. But I found the raid 0 to be getting extreamly slow read and write speeds.
Example same disks Desktop PC max 214mb/s windows vista 64 Server with centos 104mb/s
Now I am not sure but I am told that I need to align the o/s with the raid card settings but I have no idea how to do this. How to do this in plain easy step by step instructions. I mean how to calculate it, how to format the disk this way, and what files to edit where if needed. I have spent hours trying to figure out why my raid 0 is slower than a single disk.
Reproducible with Firefox 3.6.6 (installed from Ubuntu 10.04 repository), on Dell D620, Ubuntu 10.04 Steps to reproduce:
1) start Firefox from command line "firefox -P"
2) create new Firefox profile on NTFS volume (mounted with NTFS-3g)
3) add NoScript extension (through extension manager Get Add-ons), restart Firefox as suggested
4) extension is not added to Firefox In case at step 2) profile is created on Linux volume, at 4) extension is added to firefox.I'm not 100% sure, but I think this bug is related to Firefox 3.6 update (no problems with Firefox 3.5). I did not make proper investigation, but I have feeling same problem applies to Thunderbird 3.1.This issue does not allow to share Firefox/Thunderbird profile on dual boot machine (Ubuntu/WindowsXP).
I Have Configure Samba server in Centos, I need give permission like for some user(5User) can able to read and write the particular folder, and again i need give some another user(6user) can only read permission for same folder.
What are the possible problem when Windows access the file from Ubuntu got Read Only even though have a full permission to read, write and execute the file? Ubuntu to Ubuntu accessing the file there is no problem only Windows got a problem.
Ubuntu 64 bit is installed on the hard disk with two partitions: one for Ubuntu, another is NTFS partition called Shared. Before upgrading to 10.04 Shared volume was available. To mount it, it was necessary to enter the password.After upgrading to 10.04, I see two volumes: Shared and Shared_. Places menu contains Shared item. When I click it, it opens without password, and shows /media/Shared_, with correct contents. Original Shared volume appears in the media directory:
root@alex-64:/media# ls -l total 12 lrwxrwxrwx 1 root root 6 2010-04-21 19:49 cdrom -> cdrom0 drwxr-xr-x 2 root root 4096 2010-04-21 19:49 cdrom0 drwx------ 2 root root 4096 2010-05-09 08:25 Shared drwx------ 1 alex alex 4096 2010-05-17 08:56 Shared_
Shared volume is empty. Can this be fixed? It is OK to work with Shared_ volume?
I have a system with a 2TB RAID level 1 installed (2 x 2TB drives, configured as RAID1 through the BIOS). I installed Centos 5.5 and it runs fine. I now added another 2x2TB drives and configured them as RAID1 through the BIOS.
How do I add this new RAID volume to the existing logical volume?
The task is to create a TrueCrypt file on a buddy's USB HDD and copy a bunch of my stuff to the file. He runs Win7 so disk has NTFS. He has data on it that I don't want to compromise. Disk then goes back to him to run under Win7.The disk automounts just fine. Here's the mtab line:/dev/sdb1 /media/OneTouch440Plus ntfs rw,nosuid,nodev,uhelper=hal,uid=1000.Read (as user) is no problem. It looks like I should (as user) be able to write to it but I can't. Permissions show user as owner but read-only and can't be changed by owner. I've tried an fstab entry and mounting from CLI but no luck. I have not tried to manipulate the disk files with chown/chmod out of concern I might compromise other files on the drive.
I did the opensuse 11.3 clean install and get access to my NTFS volume by opening Dolphin in SU mode (is any other way ?). VLC unable to play any file from that volume, but Kaffeine does. VLC works with no issues from my opensuse ext4 partition.
(Ubuntu 10.04) I would like to change to change the ownership of one of my storage partitions from root to dad - I am currently reading through as much Ubuntu documentation as I can but the process is slow. If I gksudo nautilus and select the drive, right click/properties/Permissions the owner is set to root. If I try to change the group ownership from root to dad it looks like it momentarily does it but it stays at root.
using Pysdm as a gui for fstab - but so far I have only found out how to allow other users to mount the volume not own it. My fstab entry for this volume reads as /dev/sdb6 /media/backuphd2 ntfs-3g group=dad,users,user,owner 0 0 - it looks to me that in terms of ownership, root = 0 0 Can I find out what the ownership of dad is in terms of numbers (e.g. owner 0 1 or owner 1 1) and then change the fstab entry?
I'm setting up a dual-boot system, and want users to be able to access their stuff regardless of what OS is currently loaded. Ideally, I'd like to set it up so that the same Firefox profile is used in both Windows 7 and Linux, as well as the same "home" directories, but I don't think that is possible. At best, I plan to use shortcuts and symbolic links to make it easy to navigate. In any case, is there any major problem with setting up both Windows and Linux to use the same partition for storing user's directories? The primary shared things will be Open Office/Microsoft Office documents and Firefox setups.
I haven't decided if I'm putting Ubuntu or Fedora on this system. I'm more familiar with Fedora, but need to increase my familiarity with Ubuntu. I'm going to go with whatever will give me the least hassles with the setup I just described. On the other hand, I'm unsure if I even need to make a dual boot. I have VMWare, and I'm not sure what advantages there are to making a dual boot over VMware in my case. The only advantage I can see is:
1. Having Linux as a boot option kinda forces me to actually use it once I choose Linux. Thus, I become more familiar with it, and need to reboot the computer in order to use Widows. 2. Linux gives me an emergency boot option is the Windows section gets corrupted beyond what chkdsk and the other emergency recovery options can fix. Counterbalanced by the ability to boot the old Vista OS that came with the computer. 3. The full resources of the computer are available to Linux. Not so much an issue today, but maybe in a few years. This is counterbalanced by the fact that all my games are in Windows, and I can't think of anything else I'd do with Linux that would put such demands on the system. Yeah, I might use it as a server, but that is more to LEARN how to set up and configure servers. I believe it is against Comcast Cable's TOS to run an permanent server with the necessary dynamic DNS registration.
I have no need for a permanent DNS server. If I need name resolution, I'd just put it in my hosts file. I already use that to block ads, so sharing it with all my systems is no problem. I don't have that many. So, the only reason I can really think of is to force myself to use Linux by booting Linux, rather than take the lazy way with Windows.
I want to copy a bunch of several hundred GB to a ntfs drive.Is it a bad idea to use two different Os's? Are the files written to the drive the same way? Is there a more likely chance for corruption using different Os's to write files?
I have 64GB USB stick NTFS formated. I'd like to exchange files much bigger than 4GB between windows and linux. FAT32 doesn't support files bigger than 4GB. Is it possible to mount NTFS RW under Debian Lenny?
Can Slackware 13.37 write on Win7's NTFS? I'm dual-booting and I've been thinking upgrading to Win7. I need to write to the Windows partition from Slackware and the NTFS-write compatibility will affect my decision.
I have a raid 5 array formatted with ntfs; My Ubuntu OS is not able to recognize the raid 5 array but my windows 7 OS can. I had this working before when I installed ubuntu via wubi but now since i installed it as a dual boot OS I am having issues trying to mount this raid 5 volume. So far i have tried reinstalling the dmraid, ntfs config manager, and storage device manager however nothing seems to help me recognize my raid 5 array.
P5N32 E-SLI PLUS MOTHERBOARD: RAID 5 ARRAY NTFS with NVIDIA's raid chipset that comes built in with motherboard.
You'd think that with two backups of all my data, which are syncronised twice weekly - that I'd be pretty safe. Fine and good until in a reorganisation of my documents folders,I delete a bunch of files - and don't notice until after I've run the backup - so they're deleted from the backups as well. Cue me beating myself around the head with the keyboard a few times about a week later when I realised.I'd advise against doing that if you have a keyboard like the IBM Model-M - it hurts.Okay, so I figure it's at least worth having a stab at recovering this data. The external harddrive's not had anything written to it since then, so is probably the best candidate. It's formatted as an NTFS volume (1.5Tb).
Now, I DO have a copy of R-Studio for Windows which I bought and paid for a few years agowhen XP managed to destroy itself and the file structure on the harddrive when it fell over installing SP2 (this was the event which lead ultimately to me switching to Ubuntu).I've found this to work quite well, though the initial scan does take a while.nfortunately, it does NOT seem to work from within Ubuntu through Wine. It runs, but can't see any drives. The only Windows environment I have access to now is Vista, andR-Studio seems to hang after running for an hour or so under Vista.
Are there any tools - preferably simple enough that I can get my head around them - which I can use from within Ubuntu to have a scrub through an NTFS drive to look for and otentially recover deleted data? I've found several tools which claim to recover things from ext3/4 drives from Windows - but not the other way around!There are a fair selection of filetypes involved here, some word documents, probably most of interest to me though are some old videos, mostly <5Mb taken on my old phone camera from university. Nothing really mission critical...but memories nevertheless.
I have successfully mounted my Win7 volume and my external hard drives NTFS volume as well. However, after modifying the fstab I seem to only be getting the win7 volume to auto-mount. Below is the contents of my fstab. /dev/sdf3 is not mounting. Again, it works no problem if I manually mount it.
Im trying to recover some data from my friends laptop, since it wont boot from the harddisk anymore. From the knoppix cd i can find harddrive but when i try to access it im asked for a password. However dont know the password I have tried the password from his windows login but that doesnt work. Is there another way to access the drive so i dont have to use a password? If possible i would like to avoid removing the harddrive from the laptop. The installed OS is win7.
