  • Moving a File While It's In Use -- How Does it work?

    - by Zaz
    I've noticed that on non-windows OS.... ie linux/mac i can do things like: - Send a zip to a friend over aim - Delete the file while it's in transfer And the transfer does not fail. Or, I can do operations like.. - start a movie - erase the file - the movie still plays to completion (read from disk, not just buffered in memory) Although the files are being "deleted", as i mentioned, they are actually being moved to a different location on the file system... ie a Trash directory or something. So it seems to me like the OS uses a pointer @ the file that is updated when it moves rather than accessing the files directly. Can anyone shed some light on how this AWESOME capability is actually implemented? I'm not even sure what to google to learn more about it. thank you.

  • What character can be safely used for naming files on unix/linux?

    - by Eric DANNIELOU
    Before yesterday, I used only lower case letters, numbers, dot (.) and underscore(_) for directories and file naming. Today I would like to start using more special characters. Which ones are safe (by safe I mean I will never have any problem)? ps : I can't believe this question hasn't been asked already on this site, but I've searched for the word "naming" and read canonical questions without success (mosts are about computer names). Edit #1 : (btw, I don't use upper case letters for file names. I don't remember why. But since a few month, I have production problems with upper case letters : Some OS do not support ascii!) Here's what happened yesterday at work : As usual, I had to create a self signed SSL certificate. As usual, I used the name of the website for the files : www2.example.com.key www2.example.com.crt www2.example.com.csr. Then comes the problem : Generate a wildcard self signed certificate. I did that and named the files example.com.key example.com.crt example.com.csr, which is misleading (it's a certificate for *.example.com). I came back home, started putting some stars in apache configuration files filenames and see if it works (on a useless home computer, not even stagging). Stars in file names really scares me : Some coworkers/vendors/... can do some script using rm find xarg that would lead to http://www.ucs.cam.ac.uk/support/unix-support/misc/horror, and already one answer talks about disaster. Edit #2 : Just figured that : does not need to be escaped. Anyone knows why it is not used in file names?

  • Are filesystem operations a function of the kernel?

    - by hydroparadise
    I suppose the question would be OS specific, so I'll take the following scenarios: Winodows (NTFS) OSX (HFS) Linux (ext2,ext3,ext4) Each operating system has it's default filesystem it operates os (OSX, I beleive, only has the one choice available). I've noticed some utilities out there for OS's to read different file systems (which obvisouly is NOT apart of the kernel), which got me thinking: Are filesystem operations a function of a driver (ie, potentially modular), or is it truly apart of the kernel?

  • What Filesystem should be used for a 4TB drive for both Windows and OSX compatibility? [closed]

    - by Nicholas Yost
    Note: I am aware of similar questions. The one's I seen here are for Windows, OSX, and Linux (which I do not need). I also can use Mountain Lion, which the other questions did not mention. I was going to use NTFS, but OSX Mountain Lion can only read that filesystem and not write to it for some reason. I want to use something native between OSX and Windows, as I don't want to risk losing the data over filesystem incompatibilities. I have USB 3.0 and want something that will allow files greater than 4GB. I do not mind installing a small set of drivers on the Windows machine(s), but I would strongly prefer to leave the Mac machine untouched. Thanks!

  • What is the best file system to use for a second hard drive when dual booting between WinXP and Win7

    - by Corey
    I am dual booting for legacy reasons, and I have a 2nd internal drive that I would like to use from both XP and 7. Should I go with the standard NTFS? (will the secuirty features be an issue, with different SIDs from the different users) Should I go with FAT32? Should I try out the new exFAT? Also, I curently have two of my 3 drives as "dynamic disks" and 1 spaned volume created on them. (i did this from XP) Win7 can see them/it fine. Is this an ok thing to do?

  • My external HD turned to RAW - How to recover my data?

    - by Matan Eldan
    I have an external HD (WD MyBook Essentials) with all of my backups (1TB) for some unknown reason, when I try to connect the drive (Tried several interfaces: eSATA/plugged it into my PC/USB) I get this message: "You need to format the disk in drive M: before you can use it" I've looked in disk management at the drive, and its listed in there - with the same full capacity. The file system under disk management now says RAW and that its healthy

  • Mac OS X - detect file system read

    - by quano
    I want to know what files a specific application is trying to access on my disk. I know that you can use fs_usage, but this outputs events from all applications. I know that you can target a single application, but only one that is already running. I want to detect all readfile-events an application is trying to do, ever since it is started. I don't want to miss out on any event. How do you achieve this?

  • Does "..." have meaning as a relative pathname? (EDIT: No.)

    - by Pup
    1. Is there a relative pathname/directory/folder meaning for the expression "..."? 2. What does "..." refer to in the context cited? I encountered the expression "..." when looking at the installation instructions for http://code.google.com/p/vim-win3264/wiki/Win64Binaries and it says the following (note bolded text): Unzip the zipfile into a directory whose name ends in vim, such as C:\Program Files\Vim, D:\vim, or C:\mytools\vim. This will create a vim72 subdirectory, containing all the files. Start a cmd.exe window, cd ...\vim\vim72, then run install.exe, the command-line installer. This will offer you a series of choices. You can probably just type d to "do it".`                                               Bonus points for listing all relative directory pathnames!

  • Permission to make symbolic links in Windows 7?

    - by karolrvn
    How to enable a particular user the possibility to create symlinks in Windows 7? I searched "Group Policy" and google, but haven't found it. BTW: Is there a way to search through everything in Group Policy Editor? The filters only seem to work on particular subtrees. Actually I never found anything using the filters. TIA

  • Does uwsgi workers share a common memory ? [ With Nginx ]

    - by Yugal Jindle
    I have configured my Nginx with Django uwsgi. When the django server starts, it reads a 5MB file from the hard-disk. Now, Without Nginx with Django default server python manage.py runserver = Runs immediately and starts serving pages. Problem: With Nginx as the server It takes very long time and several HTTP 504 before it start serving pages. So, How does uwsgi workers work with Nginx ? I have: 4 Workers 512 Threads each So, is the 5MB file getting read 512 * 4 times ? Is there a possible work around for this in Nginx / Uwsgi ?

  • What filesystem to use when using both Windows and Linux?

    - by MighMoS
    I will be buying a 2TB hard drive soon, and would like to use it as media storage. I would like to be able to read/write from both Windows (version 7, 64bit) and Ubuntu Linux, and I need support for files greater than 4GB in size (so I think this rules out FAT32). I'm using IFS drives at the moment to access my linux ext4 partitions, and I find it unstable. Does this mean NTFS? Is there something else I'm missing?

  • Which is the recommended filesystem for VMware Server / ESXi?

    - by elitalon
    We have a couple of servers in office with VMware Server as virtualization solution. We are planning an upgrade of our infrastructure. Some servers will remain with VMware Server, but we want to migrate some others to VMware ESXi. In both cases we are making a fresh install, and I wonder if there any suggestion/guidelines regarding the host filesystem and its partitions. EDIT: We are using local storage instead of SAN/NAS external storage, because we are not sure if it is worth it to use them given our office size/requirements.

  • Making many network shares appear as one

    - by jimbojw
    Givens: disk is cheap, and there's plenty lying around on various computers around the corporate intranet redundant contiguous large storage volumes are expensive Problem: It would be fantastic to have a single entry point (drive letter, network path) that presents all this space as one contiguous filesystem, effectively abstracting the disk and network architecture from the paths presented to users. Does anyone know how to implement such a solution? I'm open to Windows and non-windows solutions, free and proprietary.

  • Availability of big files on multiple servers

    - by Imises
    I have to handle many (1'000 - 30'000) big files ranging from 200MB up to 2GB. The demand for these files is variable (0 - 300 downloads / file). This is why a single file must saved on 2 or more servers. My servers are placed in different datacenters (France), with different size HDDs (750GB to 4TB). Currently I share the files using PHP and ncftpget / ncftpput, but it's very slow. I need a solution to handle balancing these files across 7+ servers.

    - by Tim
    My Ubuntu 8.10 crashed due to the overheating problem of the CPU. After reboot, under gnome, all the files cannot be removed, their properties cannot be viewed and they can only be opened, although all are still fine under terminal. I was wondering why is that and how can I fix it? Thanks and regards

  • Resize2fs at 81h and counting

    - by Adam
    Setup: 12x 1TB drives in a RAID6 (MDADM) crypt-setup running ontop of MDADM LVM running on the crypted drives EXT4 on the LVM Background: I added a new drive to the RAID (increasing from 11 to 12 drives), and 'bubbled' up through the layers (MDADM, etc...) to reizing the ext4 partition. This machine is used as a centralized repository for photography and as a backup server (for both Windows and Mac machines) so bringing it down to add the drive and wait for the resizing and everything wasn't really an option. So I started the resize operation several days ago. HTOP is reporting the resize2fs operation as running for 81h now. DMESG and syslog are both clear, and the drives are still accessable. The resize command reports it's started an online resize of the partition, so the process IS running, and it is burning through 100% of one of my cores. Question: Is it normal for the operation to take this long or has something gone horribly wrong? Where would I start looking for signs of trouble?

  • iso9660 filesystem when remade with a slight change blows its size by 100M

    - by user1458001
    I have an iso 9660 filesystem image in which I need to edit just one file. I copied the files using cp -avf. When the files reach the destination, the sizes increase. That must be due to the increase in block size. But when I remake the iso9660 filesystem using mkisofs -J -U -r the sizes of the files remain the same and just a small editing in a file leads to a blow up of about 100M in the newly created iso image. I think I'm missing some option there, but I'm not able to find out in the manpage and google search. Some quick help would be greatly appreciated as I'm stuck. My host filesystem is ext3..if that's required.

  • Solution for file store needing large number of simultaneous connections

    - by Tennyson H
    So I'm fairly new to large-scale architectures. We're currently using linode instances for our project, but we're brainstorming about scaling. We need a file store system than can deliver ~50mb folders (user data) to our computing instances in a reasonable amount of time (<20 sec), and scale to 10000+ total users, and perhaps 100+ simultaneous transfers. We are also unsure whether to network mount (sshfs/nfs) or just do a full transfer store-instance at the beginning and rsync instance- store at the end. I've experimented with SSH-FS between our little Linode instances but it seems to be bottlenecked at 15mb/s total bandwith, which wouldn't do under 10+ transfer stress let alone scale v. large. I also tried to investigate NFS but couldn't get it working but have little hope that it'll do within our linode network. Are there tools on other cloud providers that match our needs? Should we be mounting, or should we be transferring? Thanks very much!

  • Copy past speed very slow for a large number of files on Windows [closed]

    - by Arno2501
    I've run the following test I've created a folder containing 15'000 files of 400 bytes using this batch : @ECHO off SET times=15000 FOR /L %%i IN (1,1,%times%) DO ( fsutil file createnew filename%%i.txt 400 ) then I copy past it on my Windows Computer using this command : robocopy LargeNumberOfFiles\ LargeNumberOfFiles2\ After it has completed I can see that the transfer rate was 915810 Bytes/sec this is less than 1 MB/s. It took me several seconds to copy 7 MBytes Please note that this is very slow. I've tried the same with a folder with a single file of 50 Mbytes and the transfer rate is 1219512195 Bytes/sec. (yeah GB/s) instantaneous. Why copying large number of files take so much time - ressources on a windows filesystem ? Please note that I've tried to do the same on a linux system which runs on the same computer in a virtual machine (vmware player) with ext3 filesystem. I use the cp command and the copy is instantaneous ! Please also note the following : no antivirus I've tested that behaviour on multiple windows computers (always ntfs) i always get comparable results (transfer rate under 1MB/s avg 7-8 seconds to copy 7 MBytes) I've tested on multiple linux ext3 system the copy is always instantaneous for that amount (15000 files of 400 bytes) The question is about understanding what makes windows filesystem so slow to copy large number of files compared to a linux one for instance.
