  • Partial-stroking / Short-stroking / Half-stroking Hard Drives?

    - by Daniel Magliola
    Could anyone here explain to me what is implied by this term? (I've seen the same thing mentioned with the 3 terms). At first when I read about it, for some reason I understood that it was some way of splitting the bytes across the platters of the disk, which sounded like a good idea and obviously doesn't make sense, because that wouldn't cut disk size in half (and disk are probably already splitting bytes across platters)... The best I've come to understand is that basically instead of creating one partition for the whole size of the disk, you create 2 partitions, and use only one of them, either the one in the "center" or the one in the "rim" of the platters, and since one of the two is faster (people didn't seem to agree on which one was faster), that makes everything better. Am I understanding this correctly? Has anyone tried this with their drives and had a good outcome? Thanks!

  • Resize a RAID 1 volume on OSX Snow Leopard - how? (Note: software raid)

    - by Emmel
    I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OSX 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable...), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

  • Defragment a file or folder? Windows 7

    - by acidzombie24
    Is there a built-in way to defragment a folder? I am using VM Player so I would like my 3 GB disk image to be defragmented if possible. FYI my disk partition that the image lies in has 12 GB left and has roughly 90% of the disk used. I probably would not need a defrag but I would like to do it if it's possible.

  • Safer RAID5 rebuilds using partially failed disks?

    - by arcticmac
    There have been lots of articles posted recently about how RAID5 is dangerous because of long resilver times, and in particular because of increasing chances of encountering a URE during the resilver. Obviously this is a significant concern. However, it seems that in many cases of interest (as long as you're keeping some kind of eye on your disks), when it comes time to rebuild the array, the disk that I'm replacing is still mostly readable. If you try to explain this predicament to the average layperson, they are typically very confused as to why you have two almost completely functional disks but can't produce one working array. It seems to me that there ought to be some way to take advantage of this to make rebuilds safer, as long as I'm willing to have the RAID5 be read-only for a couple of days while it rebuilds. Conceptually, what I have in mind looks something like this: When a disk fails, immediately take the RAID5 offline or mount it read-only Attach a new disk (either in a spare bay, or externally via eSATA) and begin rebuilding it to replace the failed one. If known, perhaps start with the stripes in which the failure occurred, to minimize the chances of losing those if another disk fails. In the event that a second disk experiences a URE or other failure during the rebuild, try to source that data from the disk that is being replaced. Presumably if this happens, more rebuilding would be necessary. When complete, shut down the server, swap the replacement drive into the original bay if desired, and bring the array back up. Obviously such a process would not be appropriate for applications where uptime is critical or data loss cannot be tolerated, but it seems to me that this could help considerably to improve the reliability of RAID5. I assume that there's not a good way to implement a recovery like this at present, given that I haven't seen any indication of tools that are designed to do this, and that it seems like it would be rather obtuse to work out manually. Are there also technical issues with it that I haven't thought of (I'm still fairly new to RAID stuff)? Any thoughts on how hard something like this would be to implement (e.g. in linux md raid)?

  • What does ESXI server do

    - by Mirage
    I installed ESXI server on my machine hoping that it will be similar to workstation where i can install virtual machines. But when i installed it , it shows one screen with no options for making virtual machines. If can't make virtual machines from ESXI , then what is it used for. I formatted my Harddisk just for ESXi but then again had to install windows and then VM workstation.

  • Reduce the I/O priority of Windows Backup (Windows Server 2008 R2)

    - by HelloSam
    I have a PostgreSQL running on Windows Server 2008 R2 x64 box. And I have scheduled a backup everyday from the RAID 1 DB disk to a dedicated standalone disk. They are SAS 15k on Dell PERC 6i. I am using the built-in Windows Server Backup for purpose. The problem is, whenever the backup process is kicked in, the database performance is hogged. I would say almost a 10x of performance reduction. From the resource monitor, the disk queue is in the double digit range when backing up, and less than 1 during the day. The disk activity is like ~30-50MB/s during backup, so I guess the hardware is acting normally, though wbengine.exe takes up most of the portions. I think reduce the IO priority of the backup process would be an answer, but I couldn't find a way to. Tuning process CPU priority does not seems to help.

  • Natively boot Virtualbox Image

    - by isync
    I am faced with a Windows hardware/software problem left over from another person. It's on me to resolve. It's a mission critical setup. The situation is: I've got a physical server machine with: -Disk C:\ (one disk) containing a basic install of Windows Server 2008 R2, formerly Win Vista Pro, now gone. -Disk D:\ (software Raid) containing a VirtualBox disk image of a configured Windows Server 2008 R2 running SQL Server R2 among others. What shall I do now? Migrate all the stuff from the configured VM to the basic but natively installed C:\ Windows Server 2008 R2 (with the possibility of breaking stuff)? Or, Setting up the machine to "natively boot" the VM with the help of bcdedit.exe (something I've read about, what I've never done, what I don't know of if it works, if it hits performance, or if it is stable for production) For me, being old skool, I am in the process of de-virtualising everything (option 1). But I'd be happy if someone suggests I am ok to go down the "natively boot" route.

  • P2V using Acronis True Image Home 10 and Windows 7

    - by Anthony
    I have a full system image using Acronis True Image Home 10 and want to run it as a virtual machine on Windows 7 Professional. I have created a virtual machine but Windows Virtual PC doesn't allow access to a USB external hard disk when booting from the Acronis Recovery CD. I've copied the backup onto the host machine and I can access it via the network using the Acronis boot CD but I'm wondering if there is an easier way? Does any other free Virtual Machine software support USB devices during boot (i.e. I can restore a backup image from the USB hard disk directly)

  • DPM 2010 iSCSI Mirror

    - by Thermionix
    We're using DPM 2010 for exchange backups, The backup Disk(s) are iSCSI attached drives from multiple NAS boxes. We'd like to mirror iqn.2009-07.com.example.example:RAID.iscsi4.vg0.iscsi05 onto iqn.2012-3.com.example.example:RAID.iscsi4.vg0.iscsi05 DPM 2010 requires the disk for itself and handles volume creation, Therefore we can't just create a mirrored volume in Disk Management. DPM itself doesn't seem to have any ability to mirror the Disks in its storage pool. Any tips on how to mirror the volumes from one drive to the other?

  • 2nd Bootable partition P2V conversion

    - by Vendoran
    I have a dual boot machine (Win7 RC and Win2008) and want to migrate one of the partitions (Win2008) into a Virtual Hard Drive and the be able to use it in VPC or Virtual Server (not Hyper-V). The ways I've seen via Linked Virtual Disks or WinImage take the entire physical drive instead of just the partition. Any ideas? Thanks in Advance, --Aaron

  • VMware and Windows Activation

    - by Peter M
    Yesterday I installed Slysoft's Virtual CloneDrive in order to mount an iso for some software installation on my host system (XP Pro SP3) This morning I fired up VMware and made a linked clone of an existing XP vm in order to do some software testing. This is the sort of thing that I do all the time, and the base XP vm that I clone was activated a long long time ago. The surprise today was that the newly cloned vm was no longer activated and XP cited major changes in hardware as the reason. I repeated the test with a full clone of the base system and got the same message. I then started up my base vm and it seemed to be activated, yet another vm (which I fully cloned from the base vm a long time ago) now started reporting that XP was not activated. At this point I guessed that Virtual DriveClone might have been the source of my hardware differences so I uninstalled it and rebooted. After this I made a new linked clone and full clone of the base vm and XP did not complain about not being activated. So I seem to be back to where I was before installing Virtual DriveClone with the exception that that one particular XP vm continues to complain about activation (even though 4 or 5 other XP vm's are fat and happy) Now to my questions: Why would adding Virtual CloneDrive to the host system affect XP activation on the vm's? From their point of view I would have thought that the environment had not changed as I had not enabled any new hard drives in their systems. Or is adding a hard drive to the host system enough to upset XP activation? Since this event, one of my fully cloned vm's is still reporting that XP is not activated even though I have removed Virtual CloneDrive. Is there anyway to convince XP that it is on the same system as yesterday? Or are my only options to do an activation or restore the vm from a previous backup?

  • How to share internet connection on Mac os x to Virtualbox vm's using Host-only

    - by redben
    In one line : is the following possible : Airport <- osx bridge - vbox-Host-only - vm's On a mac os x, i have virtual box with a virtual machine. For now i have configured 2 interfaces for my virtual machine eth0 is normal bridge for my vm to acces the internet (when airport is connected) eth1 is set to host-only so i can access my vm from the host when there is no wifi/aiport is down. So basically it's like Adapter 1 when there is Wifi, Adapter 2 when there is not. I'd like to have only one configuration to make it simpler. I thought i could just keep the Host only configuration, and on the host (os x) go to internet sharing and select "share from airport" to vboxnet0 (the vb virtual interface). Only to find out that vboxnet0 dosn't show up in the interfaces list on os x preferences. I know that on a linux host you could install something called bridge-utils and use that to bridge the two insterfaces. Is there any thing like that for Mac ?

  • Force Finder to log in as Guest to a SMB share

  • cloning a kvm guest os to a vmdk file

    - by Bond
    I have a production environment where I am having 4 Guest OS running on a Ubuntu server which uses kvm. These OS are in an LVM based setup.I want these Virtual Machines to be in a vmdk format also.Where people would do experiments with these Virtual Machines so this in a vmware environment (or it can be Xen too) would be different from the kvm server.I would not have any control on that other environment so I want to give people vmdk images of these virtual machines. The production Virtual Machines will still keep running on kvm server but the VMs on which experiments would be done would be of type vmdk.(vmdk is a constraint) Here is output of lvscan ACTIVE '/dev/abcd/lvm1' [100.00 GiB] inherit ACTIVE '/dev/abcd/lvm2' [150.00 GiB] inherit ACTIVE '/dev/abcd/lvm3' [50.00 GiB] inherit ACTIVE '/dev/abcd/lvm4' [100.00 GiB] inherit I was reading man page of qemu-img and what I understand is I need to first create a qcow image file which I need to populate and then convert that to a vmdk file. Is that understanding correct? Now suppose /dev/abcd/lvm4 is the virtual machine with which I am going to start this experiment.I can shutdown the production VMs for some time to do this. So is the following way correct to go on server 1 (where kvm is running) qemu-img convert -c -f raw -O vmdk /dev/abcd/lvm4 /backup/lvm4.img or it will affect the lvm4 on kvm server 1. I do not want the VM running on original server to at all loose its any of the content but also have a vmdk file for each of the Guest OS on kvm. Before I proceed with any of the above things on the production machine I just want to make sure that I am doing the correct thing so I asking here.

  • Hyper-V 2012 and P2000 SAS SAN

    - by user155950
    Hi I am having major problems setting up a Hyper-V 2012 cluster on a P2000 SAS SAN. Running System Center VMM 2012 SP1 I am unable to see any storage to create my cluster. Has anyone had experienced anything similar? Under fabric and storage I can't add the P2000, all I can do is use storage spaces in server manager to create a storage pool and virtual disk. This allows me to create a file share which I can add to VMM but I still can't see any disk to create a cluster. I am just about at the point where I want to tear my hair out wipe the servers and stick VMware on them because I know it works as I have set several systems up like this in the past. The Hyper-V servers can see the storage and in server manager on my management machine it seems to know both servers can see the same disk. VMM is running on the same machine and it can't see any disk. Help..... Thanks Mike

  • md5sum repeatedly gives different checksum for same file on same machine

    - by Joel
    I have a very small and quite old hard drive disk, about 32G. On to this disk I have copied a largish tar file, about 5G. When I run md5sum to generate a checksum on this file I repeatedly get different results (on the same machine and the same file). This obviously should not happen. If I repeat the experiment with a much smaller file, as expected the checksum is the same each time. I can only assume that because the large file is spanning most of the disk, and it is an old drive, I am experiencing a lot of read errors on the hard drive - and it needs replacing? Could there be any other good reason for this? Something I can do to fix the problem other than buying a new disk? Update: sha1sum also produces inconsistent results.

  • Windows OEM vs retail difference

    - by tjameson
    My laptop has an OEM version of Vista Home Premium 32-bit. I need to reinstall Windows, and I've made sure that disk I have downloaded is the same as the one on my system (32-bit Home Premium). Is the retail version the same as the OEM? I only have a retail copy but I have an OEM license. Will I have any problems reactivating my copy of windows? Note, my HW hasn't changed. Note: I saw this post already, but I don't have an OEM disk: Installing XP with out manufacturers original XP restore disk, possiable with OEM disk?

  • Postfix tutorial inconsistency

    - by Desmond Hume
    I'm following this tutorial to setup a Postfix/Dovecot mail server with Postfix Admin as a web front end. As regards directory structure for virtual mail users, the author of the tutorial writes: Virtual mail users are those that do not exist as Unix system users. They thus don't use the standard Unix methods of authentication or mail delivery and don't have home directories. That is how we are managing things here: mail users are defined in the database created by Postfix Admin rather than existing as system users. Mail will be kept in subfolders per domain and account under /var/vmail - e.g. [email protected] will have a mail directory of /var/vmail/example.com/me. But when he gives instructions about configuring Postfix Admin, he suggests this to be contained by Postfix Admin's config.inc.php: // Mailboxes // If you want to store the mailboxes per domain set this to 'YES'. // Examples: // YES: /usr/local/virtual/domain.tld/[email protected] // NO: /usr/local/virtual/[email protected] $CONF['domain_path'] = 'NO'; Is there an inconsistency?

  • How do I remove a USB drive's write protection?

    - by nate
    I have a SanDisk Cruser Blade USB stick that suddenly seems to be write protected. I tried running DiskPart but after I write the command "attributes disk clear readonly" it displays this: Microsoft DiskPart version 5.1.3565 ADD - Add a mirror to a simple volume. ACTIVE - Marks the current basic partition as an active boot partition. ASSIGN - Assign a drive letter or mount point to the selected volume. BREAK - Break a mirror set. CLEAN - Clear the configuration information, or all information, off the disk. CONVERT - Converts between different disk formats. CREATE - Create a volume or partition. DELETE - Delete an object. DETAIL - Provide details about an object. EXIT - Exit DiskPart EXTEND - Extend a volume. HELP - Prints a list of commands. IMPORT - Imports a disk group. LIST - Prints out a list of objects. INACTIVE - Marks the current basic partition as an inactive partition. ONLINE - Online a disk that is currently marked as offline. REM - Does nothing. Used to comment scripts. REMOVE - Remove a drive letter or mount point assignment. REPAIR - Repair a RAID-5 volume. RESCAN - Rescan the computer looking for disks and volumes. RETAIN - Place a retainer partition under a simple volume. SELECT - Move the focus to an object. It's like when you type help at the DiskPart prompt, so how do I get past this? This problem started when I plugged the stick into a laptop which had viruses, if that's any help.

  • collectd:Monitoring server not showing clients

    - by Quintin Par
    I have setup a monitoring server with the following setup. <Plugin network> Listen "0.0.0.0" "25826" </Plugin> Now my clients are sending data to the monitoring server(verified through tcpdump). Even the collection folder shows that the data is being dumped /var/lib/collectd/rrd [ec2-user at x rrd]$ ll total 4 drwxr-xr-x 11 root root 4096 Nov 20 17:53 x-web-1.y.com [ec2-user at x rrd]$ I have also verified with find . -mmin 1 to see if its being constantly updated. [ec2-user@x rrd]$ find . -mmin 1 ./x-web-1.y.com/interface-eth0/if_errors.rrd ./x-web-1.y.com/interface-eth0/if_packets.rrd ./x-web-1.y.com/interface-eth0/if_octets.rrd ./x-web-1.y.com/disk-xvda1/disk_time.rrd ./x-web-1.y.com/disk-xvda1/disk_ops.rrd ./x-web-1.y.com/disk-xvda1/disk_octets.rrd ./x-web-1.y.com/disk-xvda1/disk_merged.rrd But when i look it up through collectd-web, I don't see the clients What might be wrong in my setup?

  • Test server on a local network with XAMPP

    - by hopscotch1978
    Hi, I'm not very proficient with networks and could use some help. I've got a Win 7 desktop with XAMPP which acts as my local dev machine. I've configured a virtual host on the desktop which I'm able to access fine. If I'm understanding things correctly, the virtual host uses port 80 (<VirtualHost 127.0.0.1:80>). I've just tried to configure a separate Win XP laptop on the local wireless network to connect to the main desktop for testing purposes. I've added the IP address and virtual host name to my Hosts file on the laptop. My virtual host is imaginatively named "virtualhost1". When I type this into my laptop browser, it connects correctly to the main desktop and I get the XAMPP welcome screen. But I can't seem to get to the actual site, just the XAMPP welcome screen. It kind of jumps the browser to http://virtualhost1/xampp/. I think it's a port issue of some sort but I have no idea how to resolve it. I would get the same XAMPP welcome screen on my desktop if I omitted ":80" from the virtual host declaration. On my main desktop, typing "virtualhost1" to the browser address bar gives me the site correctly, not the XAMPP welcome screen. Help would be appreciated. Thank you.
