  • How to add a mirror-disk to my OpenSolaris?

    - by Sanoj
    I have a machine with two harddrives. I have installed OpenSolaris on one of them and now I want to add the other one as a mirror-drive in my zpool rpool. I guess I have to format the second disk first and then add it to the pool. How can I do this?

  • Cannot install grub to RAID1 (md0)

    I have a RAID1 array on my Ubuntu 12.04 LTS and my /sda HDD has been replaced several days ago.

Anybody can resolve this issue? I have big headache with this.

  • Dedicated hard disk for Informix SE dbname.dbs files & dedicated ramdisk for /tmp files.

    - by Frank Computer
    INFORMIX-SE 7.2: I would like to dedicate a hard disk, exclusively for my dbname.dbs directory which holds all the .dat and .idx files, and create a ramdisk for my /tmp temporary files in order to improve performance. I would also like to strip down the OS from any unecessary files and processes to minimize overhead for my dedicated application. Is this a good idea and are there any roadmaps for accomplishing this?

  • Can I use one virtualbox disk for multiple machines?

    - by mxp
    I'm not sure what search term to use and skimming through the VirtualBox manual didn't help me either, so I ask my two questions here... My setup is this: PC with dual boot into Windows 7 and a Debian operating system (both 64bit). I've created a virtual machine (Kubuntu, 64bit) under Windows and put it's VDI file on a SMB share of my NAS. Then I created a VM under linux using the same settings for memory etc and assigned the existing VDI file to it. My idea was that I could use that virtual machine from Windows and Linux as well. (1) Is this generally something that should work without problems? I noticed that snapshots get me into trouble because they appear to be not visible from the other operating system: The snapshots I took after installing the guest system are not visible under Linux. That's why I shut down the VM after usage and not save its state while it's running. My current problem is this: I have used the VM under Windows first, then under Linux. Now it will only start on Linux. When trying this on Windows the guest OS detects some kind of hard disk error and fails to boot because it cannot mount its drive. Obviously the virtual hard disk won't fail so it must have something to do with me using it under Linux. (2) How can I fix that? Update: It also looks like any changes I made in the VM under Linux have been reset by trying to boot it under Windows. Looks like it's back to the latest snapshot. I'm confused... Update The answer to my first question can be found below. In short: It works, as long as you don't use snapshots. The answer to my second question is this: Under Windows set the VM back to the latest snapshot and then discard the snapshot so it gets merged. There should be no snapshots left at the end. If you have multiple snapshots, discard the earliest ones first (Snapshot 1, then 2, 3, ...). I'm not sure what happens if you start at the end (.., 3, 2, 1). This of course leads to some data loss since you revert all changes since the last snapshot. But at least the VM is usable again.

    - by Brenda D Thomas
    I recently reinstalled windows xp on my dell latitude d410 laptop, everything works fine as long as I don't shut down, when I do, I get a black screen with a list of choices, it gives me the option of trying to start windows normally or different safe modes, than a blue screen comes up and runs a check disk, it even ask me to pick a restore point the last time, which I did, I'm afraid to turn the computer off or restart it, what could be wrong?

  • VM Virtual guest machine disk defrag improves performance, myth or reality?

    - by jafin
    In operation of a virtual Vmware or Hyper-V guest typically advice is given to defrag the host and virtual disk images so to result in improved performance. Something like a cmd: vmware-vdiskmanager -d <file.vmdk> works great. Yet I can't find any qualitive evidence that suggest defraging inside the guest VM improves performance. Does anyone have advice or evidence that doesn't come from a commercial defragger's whitepaper that suggests inside guest defragging helps?

  • Why is Core Data not persisting these changes to disk?

    - by scott
    I added a new entity to my model and it loads fine but no changes made in memory get persisted to disk. My values set on the car object work fine in memory but aren't getting persisted to disk on hitting the home button (in simulator). I am using almost exactly the same code on another entity in my application and its values persist to disk fine (core data - sqlite3); Does anyone have a clue what I'm overlooking here? Car is the managed object, cars in an NSMutableArray of car objects and Car is the entity and Visible is the attribute on the entity which I am trying to set. Thanks for you assistance. Scott - (void)viewDidLoad { myAppDelegate* appDelegate = (myAppDelegate*)[[UIApplication sharedApplication] delegate]; NSManagedObjectContext* managedObjectContex = appDelegate.managedObjectContext; NSFetchRequest* request = [[NSFetchRequest alloc] init]; NSEntityDescription* entity = [NSEntityDescription entityForName:@"Car" inManagedObjectContext:managedObjectContex]; [request setEntity:entity]; NSSortDescriptor* sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES]; NSArray* sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptors release]; [sortDescriptor release]; NSError* error = nil; cars = [[managedObjectContex executeFetchRequest:request error:&error] mutableCopy]; if (cars == nil) { NSLog(@"Can't load the Cars data!

  • How to design data storage for partitioned tagging system?

    - by Morgan Cheng
    How to design data storage for huge tagging system (like digg or delicious)? There is already discussion about it, but it is about centralized database. Since the data is supposed to grow, we'll need to partition the data into multiple shards soon or later. So, the question turns to be: How to design data storage for partitioned tagging system? The tagging system basically has 3 tables: Item (item_id, item_content) Tag (tag_id, tag_title) TagMapping(map_id, tag_id, item_id) That works fine for finding all items for given tag and finding all tags for given item, if the table is stored in one database instance. If we need to partition the data into multiple database instances, it is not that easy. For table Item, we can partition its content with its key item_id. For table Tag, we can partition its content with its key tag_id. For example, we want to partition table Tag into K databases. We can simply choose number (tag_id % K) database to store given tag. But, how to partition table TagMapping? The TagMapping table represents the many-to-many relationship. I can only image to have duplication. That is, same content of TagMappping has two copies. One is partitioned with tag_id and the other is partitioned with item_id. In scenario to find tags for given item, we use partition with tag_id. If scenario to find items for given tag, we use partition with item_id. As a result, there is data redundancy. And, the application level should keep the consistency of all tables. It looks hard. Is there any better solution to solve this many-to-many partition problem?

  • How to R/W hard disk when CPU is in Protect Mode?

    - by smwikipedia
    I am doing some OS experiment. Until now, all my code utilized the real mode BIOS interrupt to manipulate hard disk and floppy. But once my code enabled the Protect Mode of the CPU, all the real mode BIOS interrupt service routine won't be available. How could I R/W the hard disk and floppy? I have a feeling that I need to do some hardware drivers now. Am I right? Is this why an OS is so difficult to develop? I know that hardwares are all controlled by reading from and writing to certain control or data registers. For example, I know that the Command Block Registers of hard disk range from 0x1F0 to 0x1F7. But I am wondering whether the register addresses of so many different hardwares are the same on the PC platform? Or do I have to detect that before using them? How to detect them?? For any responses I present my deep appreciation.

  • Booting Ubuntu EFI on Macbook Pro Apple Bootmanager

    - by user279771
    Following: http://www.rodsbooks.com/ubuntu-efi/ and https://help.ubuntu.com/community/UEFIBooting#Detect_.28U.29EFI_firmware_processor_architecture I have ubuntu booting on my macbook pro with both refined and the native apple loader working, however, I would like to get the "Improving the Boot Method" (i believe it is called the kernel efi stub loader) working with the Apple Boot manager (the article only explains for refined), but have found no articles explaining this. Can anyone help with this? Below is what I have: What I have is the following: /dev/sda apple partitions /boot ext3 (root) ext3 swap side notes: From what I understand, I should have had my boot partition as fat32/hfs+... I can always switch it or copy the kernel to the apple EFI partition. (I tried creating /boot as an hfs+ partition during installation but was unable. Even after installing hfsprogs, although I was able to create an hfs+ partition in gparted I couldn't use the partition as /boot in ubiquity).

  • Ubuntu confuses my partitions

    - by Diego
    I have 3 relevant partitions split between 2 disks, sda2: Windows 1 partition sda3: Ubuntu partition sdb1: Data partition I was using pysdm to add a label to my partitions and somehow I seem to have screwed up my installation. Now, every time I access the Data partition mounted in /media/Data I see the files in my Windows partition, and viceversa. I've tried unmounting and remounting correctly to no avail, it seems that wherever I mount sda2, if I access that folder I get the files in sdb1, and viceversa. Anyone know what may have happened and how to solve this? Update: This is the result of blkid: /dev/sda1: LABEL="System Reserved" UUID="C62603F02603E073" TYPE="ntfs" /dev/sda2: LABEL="Windows" UUID="00A6D498A6D49010" TYPE="ntfs" /dev/sda5: UUID="033cac3b-6f77-4f09-a629-495dc866866a" TYPE="ext4" /dev/sdb1: LABEL="Data" UUID="BCD83AE3D83A9B98" TYPE="ntfs" These are the contents of my ftsab file: UUID=033cac3b-6f77-4f09-a629-495dc866866a / ext4 errors=remount-ro,user_xattr 0 1 /dev/sda1 /media/Boot_old ntfs defaults 0 0 /dev/sda2 /media/Windows ntfs defaults 0 0 /dev/sdb1 /media/Data ntfs nls=iso8859-1,ro,users,umask=000 0 0

  • How can I install Ubuntu Saucy Server with BTRFS?

    - by Walter Souto
    So, a week ago I installed the latest beta version of Ubuntu Saucy Server in a MacMini using BTRFS as only partition to mount "/" on it (I know it's not recommended to do this, but it's not the point here) with no problems et al. Everything went just "naturally"... Now with the released image of 13.10 server, I just can't get any BTRFS partition done from installer. I'm getting a "Can't create filesystem" error whenever I try to create any BTRFS partition, like the 13.10 server final installer can't handle format BTRFS partitions... Am I doing something wrong? Or it's a bug in the installer? Is there anything that I can do to workaround this and get my BTRFS partition set on installation, or I'll need to work this after the installation. I can just leave some space left and create a btrfs partition later on, with Saucy already installed and proceed to use to LXC (which is my solo purpose to have btrfs), but anyway, why installer can't do btrfs anymore?

  • Demantra Partitioning and the First PK Column

    - by user702295
      We have found that it is necessary in Demantra to have an index that matches the partition key, although it does not have to be the PK.  It is ok   to create a new index instead of changing the PK.   For example, if my PK on SALES_DATA is (ITEM_ID, LOCATION_ID, SALES_DATE) and I decide partition by SALES_DATE, then I should add an index starting   with the partition key like this: (SALES_DATE, ITEM_ID, LOCATION_ID).   * Note that the first column of the new index matches the partition key.   It might also be helpful to create a 2nd index with the other PK columns reversed (SALES_DATE, LOCATION_ID, ITEM_ID). Again, the first column   matches the partition key.

  • Netbook partitioning scheme suggestions

    - by David B
    I got a new Asus EEE PC 1015PEM with 2GB RAM and a 250GB HD. After playing with the netbook edition a little, I would like to install the desktop edition I'm used to. In addition to ubunto partition(s), I would like to have one separate partition for data (documents, music, etc.), so I could try other OSs in the future without losing the data. What partition scheme would you recommend? I usually like to let the installation do it by itself, but when I try to that I can only use the entire disk, so I don't get the desired data partition. I wish there was a way to see the recommended default partitioning scheme, then just tweak it a bit to fit your needs (instead of building one from scratch). So, how would you recommend I partition my HD? Please be specific since I never manually partitioned before. Thanks!
