Struggling with disk space or performance?

The ideal way to improve storage space to 15+ PetaBytes (PB), and transfer rates in excess of 80 GB/s: http://www.isilon.com/nl-series
Any practical experiences to share?
BTW, the NL designation is double-Dutch for 'Near Line'.

  • PXI-1031 Realtime no longer working with labview. "Insufficient disk space to perform backup"

    The realtime labview project was working until a couple weeks ago and the only error that is being shown on the PXI is this error message.
    "NI Configuration Manager: Insufficient disk space to perform backup" Everything before that looks like it's starting up just fine. I recently removed the hard drive and deleted the 4gb network log file because it seemed that a 4gb file on a fat32 file system was probably causing the problem. After doing this the project worked when I tested it but others in my lab said that it was broken again the next day.
    Any help would be greatly appreciated because I'm not all that familiar with the equipment.
    Solved!
    Go to Solution.

    In this situation, we actually want the PXI controller to be in safe mode. When the controller is reformatted, it will stay in safe mode until the proper software has been installed. Software installation is done from within safe mode, so being stuck there is a good thing.
    The networking issues you’re seeing are independent of the controller being in safe mode. Most likely, the network settings were not retained during the reformatting, and your computer needs to reconnect with the device. First, make sure that your computer is set to obtain its IP address automatically. In Windows 7, this can be configured by going to the Network and Sharing Center and clicking on Change adapter settings. From there, right click on Local Area Connection and select Properties, then select Internet Protocol Version 4 (IPv4) and click Properties. In this Window, make sure that Obtain an IP address automatically is selected.
    Once this is configured, remove your PXI controller from the chassis and flip the IP reset switch to ON. Put the controller back in the chassis and connect the PXI directly to your computer via an Ethernet cable. When you turn your PXI chassis back on, the chassis and computer should find each other and configure themselves to be on the same subnet. From there, you can set your desired network settings and install the necessary software.
    If this doesn’t work, the next step would be to check for any firewalls or antivirus that may be running. These could potentially interfere and block communication.

  • Acrobat X Pro Error when Save As JPEG: Insufficient Disk Space to Perform Operation

    Using Acrobat X Pro when trying to save a PDF as an Image - JPEG format, the Acrobat application fails with an error: "Acrobat could not save a page in this document because of the following error: Insufficient disk space to perform the operation (Page 1)". Please help with a solution to this problem. The problem is not because of insufficient disk space on my PC.

    Thank you for the reply.
    Please can you help with the location of the TEMP folder and which temporary files to delete (file type/extension). Each of the these folders include an "Adobe" Folder. Each "Adobe" folder size is less than 1MB.
    I am using Windows 8.1 Enterprise 64-bit. I have the following Adobe Acrobat applications installed: Distiller X, X Pro and Reader XI. Is this combination perhaps causing the problem?

  • Insufficient disk space to perform full backup

    Hi to all
    i'm trying to backup my acs 5.2 "backup acs repository repository  application acs" but acs gives me a critical error.

    how do i lower the data witdow in ACS view?
    thanks in adv
    Antero

    Hi
    the problem is solved now, i've openned a TAC and the cisco Guy told me how to solve it.
    in summary you need to have root access to ACS and then erase de acsview database and put a clean one.
    my acsview db has grown to 175GB., this was caused by  the misconfiguration of acsview database doesn't being backuped and the  purgin was, in this case, not being also done.
    so Brian if you hav e the same problem then you need to open a TAC case.
    Thanks

  • Deduplication: There is insufficient disk space to perform the requested operation

    Hello,
    on my Win2012R2 Fileserver is a 550GB disk with userdrives.
    I startet Data Deplication but after 100 Optimized Files the job stopped and I cannot start it again.
    If I check the Event Log I find:
    Data Deplication could not initialize change log under \\?\Volume{ID}}.... The error code was 0x8056530a, There is unsufficient disk space to perform the requested operation. (Event ID 4119)
    Then I tried to unoptimize the files with Start-DedupJob -type Unoptimization -volume "E:" but I got another error:
    HRESULT 0x8056533a, This kon will not run at the scheduled time because it requires more memory than is currently available.
    On the 550GB disk I have about 140GB free diskspace.
    The server have 8GB RAM and use 2,3GB at the moment.

  • NI Configuration Manager: Insufficient disk space to perform backup

    Hi,
    I'm having an issue with my PXI-8110 controller running LabVIEW Real-Time 10.0.1.  On start-up, I receive a message is displayed saying "NI Configuration Manager: Insufficient disk space to perform a backup"  This message just appeared.  Upon starting an FTP session I was able to see that there is only 181 megs of data on the hard drive.  In MAX, when I view the system settings of the remote PXI controller, it says that there are 0 bytes available.  I'm not sure why this is the case.  I'm not able to deploy any Veristand projects to the controller as a result.  Has anyone experienced this problem?
    Thanks,
    Cosimo

    Hello WillPwr,
    I have now had 2 different systems develop this exact error.  After the first occurrence, I assumed that it was a problem with the HD and replaced it.  Now, I am starting to worry that there may be an issue with the file management routines in LabVIEW RT.  I understand how to fix the issue, but do you have any idea of what causes the issue.  In my application, I create a temporary file to store DAQ data then save the data to a log file.  After a test is complete, the log file is transferred to a "Host" computer and the process is started again by the user when they initiate a new test.  My question: can the continuous creating and deleting of temporary files be causing the file management in the RT system to become corrupt?
    It is annoying for a customer to have to go through the process of formatting the hard drive and re-installing the software.  Not to mention that it makes the software appear to have issues...  Which it may have, but I have been very careful to close and open new files as to not develop open file references.
    Any Thoughts?
    Big Ev.

  • I am having trouble with disk space,

    I am having trouble with disk space, I am always getting the error message that I need to delete files on my start up disk, I am all out of space. I cant even save a file to my desktop without getting the message, Is there a way I can free up space. I am not very computer savvy, being a pensioner I  cannot afford expensive options.  I was familiar with the old apple imac, but I was given a macbook pro for my birthday, and am trying to work it out.  I use it mostly for photos and web.

    Jillian,
    I'm assuming this is a second-hand machine.  If it is brand new, get it to Apple because it's their problem, not yours.
    First thing you should do is go to Programs: Utilities: Disk Utlity and choose "Repair Permissions."  If you don't have the OS X system disk (a DVD) go ahead and verify the Disk. It can't fix itself, so to speak, but can tell you if there is a problem.  iIf you have the OS X system disk then boot off the disk, go to Disk Utility, and run Repair Disk.  Assuming all is OK:
    You don't need to download any programs to get started on figuring out why all your space is gone.  Try this first:
    Oh, when deleting, especially at first, you may have to move only small folders or even files, of 100 MB or so to the trash, then empty the trash.  As the free space increases, you can trash progressively larger files.  To delete files, the computer needs to create even more files to tell it what files it is deleting before it deletes them.  I know, go figure.;)
    It would not be a bad idea, and is in fact a very good idea, to run the disk utility "Repair permissions" after every half-dozen trash/empty trash cycles and then restart the computer.
    The basic plan is to search for unreasonably sized folders. 
    From the Finder:
    Open a window, click in the window and then:
    Go to menu item View. (If you click on the desktop instead of a window, you'll get a different set of view options, none of which is the one you want.)
    Click on it and move the cursor to the bottom choice, Show View Options (alternative Apple (Command)-J).  Make sure the checkbox "Calculate all sizes" is checked. If it isn't, check it and then click on "Use as default" When checked, it will show you the size of a folder.  If it was unchecked, don't be surprised if nothing seems to be happening as it will take awhile for the computer to calculate the size of, literally, thousands of folders.  But some will start to show up right away. If you open a new window and don't see any folder sizes, Repeat the Show View Options routine above and if Calculate all sizes is checked, just wait.
    I've heard you Aussies enjoy a beer or two.  If your Mac has to calculate all the folder sizes, this might well be a good time to have a cold one or two, as it will take some time.
    Go to the root level, which is "Computer" or "_Your Disk Name_," generically Macintosh under Devices in the sidebar.
    Make sure you are in list view and can have the size column visible.  Click on it (turns blue-grey) and it will sort by size, large to small or the reverse.  Click again to reverse the sort order.
    On my 10.6.8 machine, I have
    98 GB under Users.
    22 GB under Applications. If you only have the Apple-supplied applications, you probably have between 4 and 6 GB here.
    Library is 24.5 GB
    System is 4.6 GB
    Other than a few trivially small files or folders, that should be about it for the root level.
    If you have two System files, you shouldn't, and will need to get rid of one.  Ask for advice before deleting one or the other.  If you have a, "Previous System," or "Old System," -- can't remember the language, you can proably safely delete it if you are satisified with how your computer is working. 
    The Library is a candidate for bloat.  Some applications, especially those that manipulate audio or video, store the bulk of their code, generally resources of one type or the other, in the Application Support folder. For instance, I have a 10.5 GB folder of Live Type in my Application Support folder.  Honestly, I don't know what program it is for, but don't care because I upgraded to a 3/4 TB drive.  In contrast, on my 10.7.1 computer, which has little more than the Apple supplied software on it at this point, uses only 1.5 GB for Application Support.  The support folders will remain even if the program itself is deleted.  As a general rule, I wouldn't bother checking out anything under 300 MB or so.  Any folders over that, you should note for possible deletion _but_ be sure to ask someone with more knowledge about this what it is used for before deleting.  If it is used for some program that isn't on your machine, meaning the program has been deleted, you can safely delete it.  If the program is still on the machine, decide if you will use that program and, if not, delete the program and its application support files.
    My next largest folder in the Library is Audio at 2.7 GB.  I have audio editing programs, so that makes sense. You probaby have one also, but shouldn't be over 500 MB or so.
    Next is Printers at 1.4 GB.  This is a good place to clear up space.  You'll see folders with various printer brands.  Do you have a Brother printer?  No?  Trash it.  Just keep the folder with your printer brand and the PPD folder and trash the rest.  If you want to get real fancy, open your brands folder and delete the files for every model other than the one you have. 
    My next largest is Fonts at 490 MB.  Leave that alone. In fact, unless Fonts is something insane like 2 GBs, stop deleting from the Library.
    Go to Users.  There could be between one and more than one user.  (Fudge of an answer there.)  There is no such thing as a guideline for user folder size.  Is there a previous user?  If so, check with them and see if you can delete it.  I have a "dummy" administrative - level user that can be used for some esoteric rescue operations and it takes up a trivial 33 KB or something like that while my own account is pushing 100 GB.
    You'll see several folders, Music, Pictures, Desktop, etc.  This is stuff you or the previous user have created.  If you don't want it, delete it.  You will also see, aha! another Library folder.  There shouldn't be many folders over 100 MB here except for Mail and our friend Application Support.  I get a lot of mail, rarely delete any, and have carried it over from 10.3 and measures out at 3.7GB.  Still, if its someone elses mail and you don't want it, you can delete it, but again, check with more knowledgable people as there are probably some files and folders you absolutely should not delete, others that you should delete from within Mail, and some you can manually delete. 
    My Application Support Folder weighs in at 1.4 GBs, of which 1.2 GBs is for Final Vinyl.  That's a lot.  Sneaky sucker stored some untitled audio files in there.  Bye! OK, now the Application Support folder is down to 145 MB.  So, I'd say anything much over that should be investigated for possible deletion.  Close up Library and move on.
    Downloads may be very small or very large.  Depends on how meticulous the previous user was in deleting or moving to a more appropriate location.  Ask them if there is anything they want, and if no, delete it.
    My Application folder has Zero KB because I always install at the root, administrative level.  If there is anything there, figure out if you want to use it or not.  If not, trash it.
    Overall:
    1) Don't sweat the small stuff.  The days are long gone when searching a hard drive for a 100 K file to delete is worthwhile.
    2) Start small.  A disk that full is going to be pretty touchy, so once you have identified a bloated folder, go inside of it and trash the smaller files and folder, then empty the trash, then delete a few more files, empty the trash, etc. 
    3) Don't forget to periodically Repair Permissions and restarting the computer.
    4) If you are unsure about whether a folder or file can be safely deleted, ask someone knowledgable or just knock off for the day and hit it again tomorrow.  Seriously, an unanswerable question you have might well be answered by sleeping on it and attacking it the next day.
    5) As Douglas Adams wrote: DON'T PANIC!
    Best of luck!

  • Help with disk space!

    i need some serious help with disk space... so im on itunes today and it says i am running out of disk space and need to delete some files... i deleted every song in my itunes library and it stills gives me this message. i cannot download anything... i dont know what to do to clear up a large amount of disk space... please help. thanks!

    Just some obvious questions first ...did you delete the song from itunes or from a playlist? Did you empty the trash yet ..as deleted files will go to your trash but still take up space until their actually deleted from here.
    Doing a simple 'Get Info' (control + click) on certain files and folders will let you know how much space they are using. This app. also works nice in letting you know where all your space is being used...

  • Problem with disk space

    I am realtively new to using Solaris 10 6/06 and have the next problem:
    I have an Intel 4 laptop runing both Solaris and Windows XP. I mounted a FAT32 partition to share data between the two OS. Both systems access the partition just fine.
    My HDD has 80 GB capacity. I assigned 28 GB to the Windows NTFS partition, 32 GB to the shared FAT32 and the rest (about 17GB) to Solaris.
    My problem is, I started installing applications on Solaris (Sun Studio 11, Java Studio Creator 2, Netbeans IDE 5.5, MySQL Community Edition...), and while performing one of the installations, I got an alert saying I was running out of disk space. I quit installation and went to the file browser (I'm using the Java Desktop System) to check disk usage.
    Every folder (excluding de /D directory, which corresponds to the mounted FAT32) indicates that I have only 346.7 MB of free space!!!. Oddly enough, if I select, right-click and choose properties for all directories in the file system (excluding /D again and /devices), I get Contents: 206388 items, totalling 6.6 GB... remarkably less than the 17GB assigned originally. (NOTE: the /devices directory was excluded because it contains the links to the HDD devices, and "appears" to have a size of 8589934684.0 GB, which is obviously impossible.
    Any help or ideas would be very appreciated.

  • Need Help With Disk Space Issue

    I am trying to free up some disk space on my MacBook Pro. Here is what I have in terms of usage of personal files:
    Music: 24.7 gb
    Pictures: 9.92 gb
    Documents: .379 gb
    Applications: 9.25 gb
    This totals 44.249 gb
    My capacity is listed as 111.47 gb. The problem is that I am showing only 11.96 gb available. I don't understand why there is so much gab between what is listed above and the capacity. I realize the System files, Application Support, etc. use a fair amount, but it still seems like I should have more space. I have run Onyx to clear caches, optimize, etc., and that has helped, but only marginally. Are there large files somewhere I am not aware of? I have an iDisk, but I have iDisk Synching off, so there should not be a copy of it on my computer, unless tere is an old oe lurking somewhere. Thanks a lot for any suggestions.

    I'll give a very plain answer :P
    My Movies folder has a 10 gb size, my Library folder has 5.83 gb, my root Library has 10.89 gb, my System folder has 4.2 gb. I believe there is much more than the basic folders that eats your HDD away.
    I don't know if my folders size are normal, but I do know that adding only your basic folders won't give you the real amount of disk used. In my case I have 20.92 gb of space. I would also look the size of the Downloads folder and the Mail folder (in your home/Library/Mail I have 3.5 GB in one account only!)
    Hope this helps!
    One last thing, not so long ago I saw a post about someone who found a file that was huge, the file was because he let the computer working overnight testing if it ran correctly by letting chess computer vs computer play all night. The game created an enormous file (I believe it was the nbook.db file in username/Library/Application Support/Chess/)
    OR... use what Matt Clifton recommends jajaja... seems like a better idea :P

  • Disk space (a "vs. iPhoto" question)

    I'm a current user of iPhoto '08 but tried Aperture 1.5 in the past. I ended up reverting rather than purchasing the full version of Aperture because it seemed that iPhoto made better use of disk space than Aperture, due to Aperture's need to create a separate preview image. Plus with iPhoto I could click on a photo and see a representation of the full quality image, while in Aperture the previews are significantly lower quality.
    Has anything changed in Aperture 2.0? With a library of 13,000 JPEGs, which program is more efficient with disk space?
    Now let's say I switch over to shooting RAW images, which I would like to start doing more. Does that change anything?
    Needless to say I am assuming Aperture 2.0 is fully compatible with Leopard and Time Machine. That was another concern I had with 1.5.

    After you import your photos into iPhoto, you can delete the originals. In other words, if you have a folder full of images, and drag it to iPhoto, it will import them and make a copy of them. Then just delete the source folder. iPhoto makes multiple copies of photos - an original, a thumbnail version, and then a modified one that includes the edits that you make to the image. That way, you can always revert to the original version of the photo. It only makes a modified copy IF you have MADE modifications to the photos.

  • Exp/imp no data just structure uses a ton of disk space

    I am attempting to migrate a schema from one db instance to another and have run into a problem with disk space. All I want to migrate is the structure. So I am exporting with out the data. Yet the tablespace datafiles grow to a size as if they actually held data. I don't have the disk space for this and would like to know if there is a way around this problem. Also, can anyone provide some insight into why the space would be taken up even though no data is being imported.
    I am not a DBA but our DBA suggested I include a compress=n parameter. However, this doesn't appear to solve the issue.
    Thanks,
    Jason

    Go Google for "Databee" and then search their home page for the DDL Wizard
    OK, forget that: just go visit http://www.ddlwizard.com/
    (It is tricky to see on their home page).
    Feed it your row-less export dump files and turn them into a bunch of 'create xxxx' statements. Edit those statements so they aren't asking for stupid INITIAL extent sizes. Run those statements. Then do a standard import using ignore=y. That will get your tables created empty and small and the subsequent import will get all your other schema objects back.
    The DBA that suggested compress=n is on the right track: compress=y will mean import will seek to create empty tables as big as the fully-populated table currently is, pre-allocating all the space it thinks the table will eventually need given the amount of data that might, one day, be inserted into it.
    Compress=n will seek to create the table with the smallest requested extent size and no more than that: row inserts will make it grow big later on, but that growth is left to happen when it needs to happen.
    The only other potential fly in the ointment is, as someone else said, the fact that if you're importing into a tablespace that has been created 'extent management local uniform size 100M', then the mere fact of creating a completely empty table will cause 100M of space to be consumed. You would be much better off making sure your tablespaces are created 'extent management local autoallocate': then you start of with small space allocations and only get bigger when you really need it.

  • Disk Space Issues

    Does anyone out there have best practice insights on how to deal with disk space issues on the database server?  Can we copy the files onto different drives and then rename the drives?  Will everything with the BPC application sync up again?

    Hi Grant,
    I once had to move the SQL database files from one drive to another. The only thing that I did was 'Detach the SQL database' in Enterprise Manager, move the files and 'Attach these files again. Everything else was automatically changed.
    You can attach/detach using sql statements or using the graphicall user interface from SQL.
