  • Installed 11.10 on shared drive, when other partition mounted, HDD shown full

    - by Thebetpet
    I just partitioned a 500GB HDD 50%-50%. I installed ubuntu 11.10 on one half and copied a load of files onto the other. When I don't mount the other partition, it shows I have used 12.1GB and have about 240GB free. The second I mount the other partition, I can't copy any files over and get a disk full message. There is about 10-20GB Free on the other partition. Am I doing something wrong or is this a bug?

  • Swap space maxing out - JVM dying

    - by travega
    I have a server running 3 WordPress instances, MySql, Apache and the play framework 2.0 on 64m initial & max heap. If I increase the max heap of the JVM that play is running in even by 16m I see the 128m of swap space steadily fill up until the the JVM dies. I notice that it is only when I am plugging away at the wordpress sites that the JVM will die. I assume this is because the JVM is not asking for memory at the time so gets collected. I notice that when I restart Apache I reclaim about half of my swap and RAM. So is there some way I can configure apache to consume less memory? Also what could be causing the swap space to get so heavily thrashed with just 16m added to the max heap size of the JVM? Server running: Ubuntu 12.04 RAM: 408m Swap: 128m Apache mods: alias.conf alias.load auth_basic.load authn_file.load authz_default.load authz_groupfile.load authz_host.load authz_user.load autoindex.conf autoindex.load cgi.load deflate.conf deflate.load dir.conf dir.load env.load mime.conf mime.load negotiation.conf negotiation.load php5.conf php5.load proxy_ajp.load proxy_balancer.conf proxy_balancer.load proxy.conf proxy_connect.load proxy_ftp.conf proxy_ftp.load proxy_http.load proxy.load reqtimeout.conf reqtimeout.load rewrite.load setenvif.conf setenvif.load status.conf status.load

  • Erase just the free space on my hard drive

    - by Patriot
    I'm about to give away an older computer with just the Windows XP operating system intact and all other programs uninstalled. However, upon peeking at the "free space" with software called "Recuva", I notice lots of deleted things that could be recoverable. Some of these include sensitive data files, pdfs, and other personal items that I would not want retrieved. I ran a program called "Eraser" to try and overwrite that data, but it failed to do an adequate job. I also tried to do the job with "Glary Utilities" but it failed too. Short of installing a new, very cheap hard drive and re-installing the bare bones operating system, I'm out of ideas. EDIT - WOW!!! I was not really expecting this many GREAT ideas. My next question is this. If I go the DBAN route and truely wipe the hard drive, then restore my disc image (I use Acronis True Image) will it also restore the free space data? Does imaging just copy readable data? I have an old image of when the OS was first installed.

  • CouchDB crashes at startup when path to config file has space(s)

    - by Barry Wark
    I'm hoping to run CouchDB as a per-user Launch Agent on OS X. I'm using the coucdbx-core folder from the CouchDB Server.app as the base of my CouchDB deployment. I'd like each user to have their own couch instance (on a different port), necessitating separate config files for each instance. The logical place to put these files is in ~/Library/Application Support/ for each user. I can put the entire distribution in ~/Library/Application Support/my-app/coucdbx, and put the .ini at ~/Library/Application Support/my-app/local.ini. Starting couchdb as bin/couchdb -a ../local.ini (from ~/Library/Application Support/my-app/coucdbx) works great. But I'd like to save every user the ~50MB couchdbx and install the couchdbx-core in a shared location (e.g. within my app's .app bundle). When I do this, the path to the per-user config file contains a space, and I get the following error when starting CouchDB: $ bin/couchdb -n -a ~/Library/Application\ Support/us.physion.ovation/default.ini {"init terminating in do_boot",{{badmatch,{error,{bad_return,{{couch_app,start,[normal,["/Users/hs/prj/build-couchdb/build/etc/couchdb/default.ini","/Users/hs/prj/build-couchdb/build/etc/couchdb/local.ini"]]},{'EXIT',{{badmatch,{error,{error,enoent}}},[{couch_server_sup,start_server,1,[{file,"/Users/hs/prj/build-couchdb/dependencies/couchdb/src/couchdb/couch_server_sup.erl"},{line,56}]},{application_master,start_it_old,4,[{file,"application_master.erl"},{line,274}]}]}}}}}},[{couch,start,0,[{file,"/Users/hs/prj/build-couchdb/dependencies/couchdb/src/couchdb/couch.erl"},{line,18}]},{init,start_it,1,[]},{init,start_em,1,[]}]}} Is there any way to provide a config file at the command line, if that config file's path includes space(s)? Despite my best efforts in the mailing list archives, wiki and google, I haven't been able to find a solution or a definitive "it can't work". Any help greatly appreciated.

  • Shrink a Volume Group in LVM / Linux in order to install Windows on the freed space

    - by Stephan Kristyn
    I have a Volume Group with Unused space. This 40Gig should become an entidy in order to install Microsoft windows 7 on it. I do not have extra space on the drive - that is why I want to shrink the VG! LVG berta resides on sda2 and consists of lv_root lv_swap unused_space I want it to become lv_root lv_swap and have a seperate entidy made out of unused_space. Microsoft Windows 7 has to get installed on this entidy. I do not understand why Linux made simple things complicated. I utterly hate LVM and think its absolute bollocks. Useful Sources: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-system-config-lvm.html Edit: I found the answer. The necessary steps depict how complicated LVM really is. In my opinion it is best to avoiding LVM until pvresize matures as promised in its man pages. Answer: http://fedorasolved.org/Members/zcat/shrink-lvm-for-new-partition If you run into problems when you want to remove lvswap even if in resuce mode, then try swapoff /dev/vg_1/lv_swap lvchange -an /dev/vg_1/lv_swap

  • lvm mirroring space unavailable.

    - by Bryan Ward
    I am trying to migrate my data on lvm to two new disks, and setup mirroring between the two. I have successfully migrated all of the data to the first of the two disks, leaving the second one completely available as a mirror. I verified this using pvdisplay -m /dev/sd{g,h}1 --- Physical volume --- PV Name /dev/sdg1 VG Name vg PV Size 931.51 GiB / not usable 3.19 MiB Allocatable yes PE Size 4.00 MiB Total PE 238466 Free PE 82866 Allocated PE 155600 PV UUID v2nc3j-EFBR-QpuG-xgro-Rm59-fmu6-IB3QcR --- Physical Segments --- Physical extent 0 to 49999: Logical volume /dev/vg/videos Logical extents 0 to 49999 Physical extent 50000 to 99999: Logical volume /dev/vg/home Logical extents 0 to 49999 Physical extent 100000 to 129999: Logical volume /dev/vg/music Logical extents 0 to 29999 Physical extent 130000 to 155599: Logical volume /dev/vg/videos Logical extents 50000 to 75599 Physical extent 155600 to 238465: FREE --- Physical volume --- PV Name /dev/sdh1 VG Name vg PV Size 931.51 GiB / not usable 3.19 MiB Allocatable yes PE Size 4.00 MiB Total PE 238466 Free PE 238466 Allocated PE 0 PV UUID LuTrem-WcsZ-qw7l-2CDS-lLKI-wdq0-QEXhLf --- Physical Segments --- Physical extent 0 to 238465: FREE Then when I try to mirror the home logical volume for example, it says that I do not have sufficient space. I used lvconvert -m1 vg/home and the output was: Insufficient suitable allocatable extents for logical volume : 50000 more required Unable to allocate extents for mirror(s). This puzzling to me because it appears as if there is plenty of space on the second disk to mirror. Is there something I have done wrong here? Or is there a way to explicitly tell LVM where to put each leg of the mirror? I'm using lvm2.

  • Linux - preventing an application from failing due to lack of disk space [migrated]

    - by Jernej
    Due to an unpredicted scenario I am currently in need of finding a solution to the fact that an application (which I do not wish to kill) is slowly hogging the entire disk space. To give more context I have an application in Python that uses multiprocessing.Pool to start 5 threads. Each thread writes some data to its own file. The program is running on Linux and I do not have root access to the machine. The program is CPU intensive and has been running for months. It still has a few days to write all the data. 40% of the data in the files is redundant and can be removed after a quick test. The system on which the program is running only has 30GB of remaining disk space and at the current rate of work it will surely be hogged before the program finishes. Given the above points I see the following solutions with respective problems Given that the process number i is writing to file_i, is it safe to move file_i to an external location? Will the OS simply create a new instance of file_i and write to it? I assume moving the file would remove it and the process would end up writing to a "dead" file? Is there a "command line" way to stop 4 of the 5 spawned workers and wait until one of them finishes and then resume their work? (I am sure one single worker thread would avoid hogging the disk) Suppose I use CTRL+Z to freeze the main process. Will this stop all the other processes spawned by multiprocessing.Pool? If yes, can I then safely edit the files as to remove the redundant lines? Given the three options that I see, would any of them work in this context? If not, is there a better way to handle this problem? I would really like to avoid the scenario in which the program crashes just few days before its finish.

  • free up not used space on a qcow2-image-file on kvm/qemu

    - by bmaeser
    we are using kvm/qemu with qcow2-images for our virtual machines. qcow2 has this nice feature where the image file only allocates the actually needed space by the virtual-machine. but how do i shrink back the image file, if the virtual machine's allocated space gets smaller? example: 1.) i create a new image with qcow2 format, size 100GB 2.) i use this image to install ubuntu. installation needs about 10 gb, the image-file grows up to about 10GB. nothing unexpected so far. 3.) i fill up the image with about 40 GB of additional data. the image-file grows up to 50GB. i am ok with that :-) 4.) this is where it gets strange: i delete all of the 40GB data on the image, but the image-size still eats up 50GB. question: how do i free up that 40GB of data and shrink the image to the only needed 10 GB? thanks in advance, berni

  • Missing drive space in Server 2003

    - by Tim Brigham
    I have two drives used for SQL backups which for the last week have been acting strange - the free space indicated by windows is far off from what windirstat, etc indicates. There should only be about 60 GB of drive space used and there is about 160. This would match the utilization if the two last backup files were still residing on disk. SQL server is 2000, OS Server 2003 x64. Running on a VMware 5.0 cluster. OSSEC and McAfee for this system shows clean. My current plan is to temporarily attach one of these drives this drive to another VM for analysis. Is there anything more I should be looking at? There were a lot of pages on the net when I was looking for documentation on this issue but I haven't found this case described. EDIT: Unfortunately even a full reboot did not clear this behavior. I also used process explorer to look for open file handles. No dice.

  • Network external hard drive reports not enough free space

    - by mzhang
    I'm running an Ubuntu (10.04) Samba server on a local network. The server has a 50GB internal drive with only 24MB free. I've shared a folder /samba from that drive. I also have a 1TB NTFS external hard drive mounted to the system. There is a symbiotic link from the Samba shared folder on the nearly-full internal drive to the plenty-of-free-space external drive (i.e. /samba/external_hd). I wish to copy a 3.25GB folder into the (remote) external hard drive, via a Mac (10.6.8). The Mac reports (correctly) that there's 24MB free on the server, and so will not let me copy the folder on the Mac over to the external drive (dragging the folder into /samba/external_hd), failing with a "server does not have enough free space" error. However, it seems that I can still scp the folder into the external drive, via the symbolic link. Is there a reason as to why this is happening (and are there any ways to prevent it)? Is this even good practice (to mount a drive and link into the directory)?

  • Simple encryption - Sum of Hashes in C

    - by Dogbert
    I am attempting to demonstrate a simple proof of concept with respect to a vulnerability in a piece of code in a game written in C. Let's say that we want to validate a character login. The login is handled by the user choosing n items, (let's just assume n=5 for now) from a graphical menu. The items are all medieval themed: eg: _______________________________ | | | | | Bow | Sword | Staff | |-----------|-----------|-------| | Shield | Potion | Gold | |___________|___________|_______| The user must click on each item, then choose a number for each item. The validation algorithm then does the following: Determines which items were selected Drops each string to lowercase (ie: Bow becomes bow, etc) Calculates a simple string hash for each string (ie: `bow = b=2, o=15, w=23, sum = (2+15+23=40) Multiplies the hash by the value the user selected for the corresponding item; This new value is called the key Sums together the keys for each of the selected items; this is the final validation hash IMPORTANT: The validator will accept this hash, along with non-zero multiples of it (ie: if the final hash equals 1111, then 2222, 3333, 8888, etc are also valid). So, for example, let's say I select: Bow (1) Sword (2) Staff (10) Shield (1) Potion (6) The algorithm drops each of these strings to lowercase, calculates their string hashes, multiplies that hash by the number selected for each string, then sums these keys together. eg: Final_Validation_Hash = 1*HASH(Bow) + 2*HASH(Sword) + 10*HASH(Staff) + 1*HASH(Shield) + 6*HASH(Potion) By application of Euler's Method, I plan to demonstrate that these hashes are not unique, and want to devise a simple application to prove it. in my case, for 5 items, I would essentially be trying to calculate: (B)(y) = (A_1)(x_1) + (A_2)(x_2) + (A_3)(x_3) + (A_4)(x_4) + (A_5)(x_5) Where: B is arbitrary A_j are the selected coefficients/values for each string/category x_j are the hash values for each string/category y is the final validation hash (eg: 1111 above) B,y,A_j,x_j are all discrete-valued, positive, and non-zero (ie: natural numbers) Can someone either assist me in solving this problem or point me to a similar example (ie: code, worked out equations, etc)? I just need to solve the final step (ie: (B)(Y) = ...). Thank you all in advance.

  • Create a model that switches between two different states using Temporal Logic?

    - by NLed
    Im trying to design a model that can manage different requests for different water sources. Platform : MAC OSX, using latest Python with TuLip module installed. For example, Definitions : Two water sources : w1 and w2 3 different requests : r1,r2,and r3 - Specifications : Water 1 (w1) is preferred, but w2 will be used if w1 unavailable. Water 2 is only used if w1 is depleted. r1 has the maximum priority. If all entities request simultaneously, r1's supply must not fall below 50%. - The water sources are not discrete but rather continuous, this will increase the difficulty of creating the model. I can do a crude discretization for the water levels but I prefer finding a model for the continuous state first. So how do I start doing that ? Some of my thoughts : Create a matrix W where w1,w2 ? W Create a matrix R where r1,r2,r3 ? R or leave all variables singular without putting them in a matrix I'm not an expert in coding so that's why I need help. Not sure what is the best way to start tackling this problem. I am only interested in the model, or a code sample of how can this be put together. edit Now imagine I do a crude discretization of the water sources to have w1=[0...4] and w2=[0...4] for 0, 25, 50, 75,100 percent respectively. == means implies Usage of water sources : if w1[0]==w2[4] -- meaning if water source 1 has 0%, then use 100% of water source 2 etc if w1[1]==w2[3] if w1[2]==w2[2] if w1[3]==w2[1] if w1[4]==w2[0] r1=r2=r3=[0,1] -- 0 means request OFF and 1 means request ON Now what model can be designed that will give each request 100% water depending on the values of w1 and w2 (w1 and w2 values are uncontrollable so cannot define specific value, but 0...4 is used for simplicity )

  • Network Error: no buffer space available

    After some time of running fine, one of our Windows XP SP3 machines does not open some(!) new TCP/IP connections anymore. Putty says "Network Error: no buffer space available", IE won't open any new connections but e.g. network drive mappings still work, even new ones can be established. netstat does not show more open connections that usual, ping and dns lookups work fine. Any hints?

  • Windows 7 detects my 1 TB disk as a disk with only 31 MB space

    - by ZelluX
    I've added another 1 TB Western Digital disk on my computer (there is a disk with 250 GB already), and after booting to Windows 7, it recognise the disk, but in the Disk Management panel, it says the disk has only 31 MB TOTAL space, so is what it shows in the EVEREST information. And when I rebooted the computer and entered BIOS, it said the new disk has 0 MB disk capacity. Is there any way to fix this problem?

  • Missing HDD space - says 65GB used, selecting all folders shows 30GB used

    - by Igor K
    Hi Running Windows Server 2008, 74GB raptor drive and noticed we only had about 500MB left - yikes! So deleted some old backups we don't need, but can't track down where about 30GB seems to be taken up. If I go to C: and select all folders and go to properties, this comes to around 30GB but in My Computer I can see 65GB is used. How can I find out whats eating the space? Just IIS + MSSQL Express + Smartermail on the server

  • Explorer: programmatically select file/directory with space in the path

    - by Mike L.
    When I try to select a file or directory which has a space in its path in the Windows Explorer, it selects a completely different directory: explorer.exe "/select,C:\Program Files\foobar" I've tried it from Java with Runtime.getRuntime().exec(new String[] { "explorer.exe", "/select," + filePath }); and with the above command line. In both cases, the same result. What can I do to solve the problem?

  • Windows Live Messenger stops space bar working

    We have a classic ASP application that's under significantly more load than usual. We are from time to time been getting "out of memory" and "out of string space" in the httperr. We do not usually see these errors. For the moment we cannot change the application. Is there anything we can do to the IIS config which will help to reduce or stop these errors occurring ? The application pool is set to default values currently.
