  • How to mount read-only filesystem as read-write?

    - by Eric
    this is my problem. I have a USB drive which somehow was set as read-only. I want to set it as read write then format it. sudo chown -R eric /dev/sdb Seems to go through, but when I view the drive in Nautilius it says Error mounting: mount: block device /dev/sdb1 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful inf.o is found in syslog - try dmesg | tail or so. Thanks in advance!

  • Linux disk IO load breakdown, by filesystem path and/or process?

    - by Ryan B. Lynch
    Does anyone have experience with a tool that can provide an indication of disk IO load by filesystem path. I use to 'iostat' utility, frequently, to learn how much disk activity is taking place on a Linux host. 'iostat' provides a per-device breakdown, so you can see activity on a particular block device. But it doesn't go any deeper than that--you can't, for instance, query the write load generated by 'httpd' in the directory '/var/log/httpd/'.

  • How best to copy an SD card with corrupt filesystem to attempt recovery?

    - by pdbartlett
    I have an SD card with a corrupt filesystem, so wanted to clone it and attempt recovery on the copy (just in case of problems). I was thinking that dd-ing it Linux would be a sensible way to go, but don't really want to experiment in this situation. So if anyone has done this before then it would be good to know the exact approach that works. In case it helps, I have Ubuntu, OSX and Windows machines available. TIA, Paul.

  • Nokia 5800 - Where are contacts, sms and other non-media stuff on the filesystem ?

    - by AntonAL
    I have Nokia 5800 and want to import contacts, sms and other non-media(music, video) stuff to my Mac. I have connected to the phone via bluetooth with "Nokia Multimedia Transfer" application, which i downloaded from Nokia.com. I see the filesystem, that is devided to phone's memory and memory card. They are much configurations files on that filesystems, but i have not found the files, which stores the desired stuff (sms, contacts). Where are they ?

  • Virtualbox for Mac OS X - using an external USB drive, which filesystem is ideal?

    - by bencnscp
    Assuming that I am NOT going to add NTFS drivers that allow read+write of NTFS partitions, I was wondering if the choice of filesystem when I partition an external USB drive matters. The choices appear to be HFS+ vs. FAT32. For the time being, I simply created two half-sized paritions, one of each type. :) I plan to run various versions of Windows, and keep the VirtualBox files on the external drive.

  • Rsync to a WebDAV filesystem on OSX copies all files regardless of being changed or not.

    - by MarceloR
    I am trying to sync my (Mac) desktop, with an iPad and an iPhone. OSX mounts WebDAV as a native filesystem, but syncing results in all files in my directory structure being copied again. This occurs when I use rsync -a or even a simple rsync -r. Various iPhone OS apps use the WebDAV server in iPhone OSX to transfer files. This occurs on several apps I use including GoodReader.

  • Tracking down rogue disk usage

    - by Amadan
    I found several other questions regarding the theory behind my problem (e.g. this, this), but I don't know how to apply the answers to my machine. # du -hsx / 11000283 / # df -kT / Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/csisv13-root ext4 516032952 361387456 128432532 74% / There is a big difference between 11G (du) and 345G (df).

  • Running resize2fs on /

    - by user42363
    I'm trying to resize an ext4 filesystem on a Fedora 11 box. Using fsdisk and lvm, I was able to grow the partition and logical volume containing the filesystem. When I try to run resize2fs on the device containing the filesystem (/dev/sda2 in this case), I get: "Device or resource busy while trying to open /dev/sda2, Couldn't find valid filesystem superblock" I've tried this from a rescue disk that doesn't have the filesystem mounted, no joy. Maybe resize2fs doesn't know about ext4?

  • Can PyAMF support service deployment by way of the filesystem?

    - by Chris R
    I'm evaluating PyAMF to replace our current PHP (ugh) AMF services framework, and I'm unable to find the one crucial piece of information that would allow me to provide a compelling use case for changing over: Right now, new PHP AMF services are deployed simply by putting the .php files in the filesystem; the next time they're accessed, the new service is in play. Removal of a service is as simple as deleting the .php file that provided it, and updating it is correspondingly simple. I need that same ease-of-deployment from PyAMF. If we have to rewrite our installers to deploy these services, it'll be a nonstarter. So, what I need to know is, can PyAMF support new service discovery by way of the filesystem, can it support service upgrading and removal by way of same, and if so, what is the best way to set it up to do this? I'm open to any of the various server options; I can easily have cherrypy, django, whatever installed and running on its own, and even -- with a bit more sturm nd drang -- have mod_python or mod_wsgi made available.

  • How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

    - by moogeek
    Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!

  • Is it a good idea to use only a key to encrypt an entire (small) filesystem?

    - by Fernando Miguélez
    This question comes as part of my doubts presented on a broader question about ideas implementing a small encrypted filesystem on Java Mobile phones (J2ME, BlackBerry, Android). Provided the litte feedback received, considering the density of the question, I decided to divide those doubts into small questions. So to sum up I plan to "create" an encrypted filesystem for for mobile phones (with the help of BoucyCastle or a subset of JCE), providing an API that let access to them in a transparent way. Encryption would be carried out on a file basis (not blocks). My question is this: Is it a good idea to use only a simmetric key (maybe AES-256) to encrypt all the files (they wouldn't be that many, maybe tens of them) and store this key in a keystore (protected by a pin) or would you rather encrypt each file with an on-the-fly generated key stored alongside each file, encrypting that key with the "master" key stored on the keystore? What are the benefits/drawbacks of each approach?

  • Hyper-V Ubuntu 10.04, Filesystem suddenly becomes Read-Only?

    - by Daniel Upton
    We are running a Ubuntu 10.04 VM on a Hyper-V system, The VM is dedicated to running one of our web applications. We have enabled the Hyper-V drivers in /etc/initramfs-tools/modules like so: hv_vmbus hv_storvsc hv_blkvsc hv_netvsc And updated the kernel image like so: $ update-initramfs -u And all was good... until.. This morning i got a support request that our web application was throwing an error 500, so i checked the logs and nothing was there. Then I remembered that I had seen this on another of our ubuntu servers so I... $ touch foo.txt And my suspicions were confirmed: touch: cannot touch `foo.txt': Read-only file system Why is the filesystem randomly becoming readonly? Is this only in Ubuntu on HV? Is it a problem on RedHat or Cent?

  • Best filesystem for an external drive? ExFAT?

    - by GiH
    What is the best filesystem for use with multiple OS's? I saw this question but its old and doesn't take into account ExFAT. Here is what I know from my findings: NTFS - Can't write from Mac FAT32 - Doesn't support files larger than 4GB HFS - Only mac ExFAT - ??? I don't know much about this but it seems like it got rid of the 4GB limit of FAT32 and can be read on Windows, Mac, and Linux. Is ExFAT the best bet? I tried formatting the drive in ExFAT just now, but on Windows XP SP3 it was showing up as not formatted... It seems to me like FAT32 is still the best, but I wanted to see what other people had to say.

  • A space-efficient guest filesystem for grow-as-needed virtual disks ?

    - by Steve Schnepp
    A common practice is to use non-preallocated virtual disks. Since they only grow as needed, it makes them perfect for fast backup, overallocation and creation speed. Since file systems are usually based on physical disks they have the tendency to use the whole area available1 in order to increase the speed2 or reliability3. I'm searching a filesystem that does the exact opposite : try to touch the minimum blocks need by an aggressive block reuse. I would happily trade some performance for space usage. There is already a similar question, but it is rather general. I have very specific goal : space-efficiency. 1. Like page caching uses all the free physical memory 2. Canonical example : online defragmentation 3. Canonical example : snapshotting

  • How can I audit a Linux filesystem for files which have been changed or added within a specific time

    - by Bcos
    We are a website design/hosting company running several sites on a Linux server using Joomla 1.5.14 and recently someone was able exploit a vulnerability in the RW Cards component to write arbitrary files/modify existing files on our filesystem enabling them to do some nasty things to our customers sites. We have removed vulnerable modules from all sites but are still seeing some problems. We suspect that they still have some scripts installed and need a way to audit anything that has been changed or added in the last 10 days. Is there a command or script we can run to do this?

  • What is the best filesystem for storing thousands of files in one dictionary-like id-blob structure?

    - by Ivan
    What filesystem best suits my needs? Thousands or even millions of files in one directory. Good (ext4 & ntfs level or close) reliability (incl. fault tolerance) and access speed. No directories actually needed, as well as descriptive names, just a dictionary-like structure of id-blob pairs is all I need. No links, attributes, and access control features needed. The purpose is a file storage where all the metadata (data describing all the facts about what the file actually contains and who can access it) is stored in a MySQL database. As far as I know common filesystems like NTFS and ext3/4 can go dead-slow if there are too many files placed in one directory - that's why I ask.

  • What's a good tool for collecting statistics on filesystem usage?

    - by Kamil Kisiel
    We have a number of filesystems for our computational cluster, with a lot of users that store a lot of really large files. We'd like to monitor the filesystem and help optimize their usage of it, as well as plan for expansion. In order to this, we need some way to monitor how these filesystems are used. Essentially I'd like to know all sorts of statistics about the files: Age Frequency of access Last accessed times Types Sizes Ideally this information would be available in aggregate form for any directory so that we could monitor it based on project or user. Short of writing something up myself in Python, I haven't been able to find any tools capable of performing these duties. Any recommendations?

  • Is there a filesystem that is "friendly" to both windows and Linux?

    - by Somebody still uses you MS-DOS
    I'm planning to install Ubuntu 10.04 with Windows 7. (I'm new to Linux, have to use at work so I'm planning to install it at home to learn more) I plan to use a partition to my Windows system files (C:), a partition for my personal files that already exists (D:) and a new partition for Linux. What I want is to have a partition for my personal files that works across these systems - so, if I start with Windows or Linux, there's the same "Videos", "Pictures", "Projects" folders. Is it possible? Is there a hd filesystem capable of having writes from both systems without too much risk of corrupting or something?

I've read some horror stories of corruption, and would like to know from a sysadmin POV all the risks involved in such scenario.

  • How to calculate proper amount of inode/block sizes for a linux filesystem.

    - by Donatello
    I have an old reiser filesystem which I'm going to convert to Ext3. The problem I have is to determine the proper block- and inode-sizes for this partition. The partition is 44 GB large and has to hold 3,000,000+ files of sizes between 1 kb and 10kb, how can I figure out the best ratio of inodes and blocksize? The below is something I tried which seems OK but makes the copying files incredibly slow. mkfs.ext3 -t ext3 -c -c -b 1024 -i 4096 -I 128 -v -j -O sparse_super,filetype,has_journal /dev/sdb1 Thanks.
