• Poor performance during copy/clone a VM disk

  Hello

  for several days, we try to find a solution to improve performance when the computer images virtual of one ESXi (free) to another.

  Our situation is as follows:

  We have 4 different servers ESXi running, must benefit from all the material according to the compatibility of the VMWares guide. Connected via gigabit, all virtual machines network has stopped, nothing else running on the network. All virtual machines are stored locally on SATA drives.

  Now we wanted to spend a bunch of computer images virtual of one ESXi for others - but regardless of what technique, we used, we have reached a maximum. Speed about 10 MB/s (which would take several days to transfer everything).

  We tried the following:

  -Enable SSH and SCP allows you to copy the files directly between servers (using several different encryption algorithms)

  -Use Veeam FastSCP for copy files directly

  -Connect through SSH on both sides and has used a combination of tar and netcat to push raw on the network files

  -Install ProFTPD and copy files via FTP

  For all of these methods, the write speed was never over the ~10MByte/s (often it is still slower). So we thought that the networking might have a problem, that's why we tried a few transfers the.

  But even a local "dd" to transfer data of 1 local disk to another was just as slow as the transfer of network... We tried this on all the different materials of ESXi we have, with the RAID on, off, etc.

  After some googling, we discovered that this should be a problem with the VMFS that really does not support the use of "standard" file system tools That's why we tried to find a way to use the ESX-internal tools to copy/clone VM images.

  We installed a NFS server 'between' 2 ESXi servers, i.e. both have the NFS share accessible. Copy of ESXi to NFS is incredibly fast (via vSphere client, operating at gigabit full speed) - but the copy of NFS to ESXi is slow again (as before ~10MByte/s). The last test we did was use the vmkfstools command line utility to clone from the NFS share on the local disk of VMFS. This seems to be a little faster (difficult to measure due to missing statistics, seems to be ~20MByte/s), but far from a quick fix.

  What is the mechanism to move a virtual computer image on a server ESXi? Is there a way to improve the transfer speed?

  Yes, he does. As I said, this problem (poor local disk IO performance observed in ESXi, but not in the virtual machine) can be eliminated only by 'mature' raid-controller with large onboard cache, usually 512 MB - 2 GB (or storage network, of course, but now we are talking about local drives).

  It does not matter if you have a local drive attached to the controller chipset or raid - without performance cache controller is just as bad. In fact, it can be even worse on raid-controller (without cache) If you use raid5/6 to parity calculations...

• Cannot remove security file Carbon Copy Cloner in El Capitan

  OS X on Macbook Pro 10.11.2.  I dragged Net Carbon Copy Cloner file to the trash and tried to empty the trash.  I get a series of error messages indicating that the various files may not be emptied because they are currently in use.  I tried to empty the Recycle Bin by using Terminal Server and freeware, Trash it! but receive the error messages that the action is not allowed.  I've never had such a problem before.  This represents nearly 5 GB of files that I can't remove.  Help, please.

  Open Carbon Copy Cloner, disable the SafetyNet feature, then clone again.

  all files that are not on your original drive will be deleted on the clone.

• Copy/clone DB for Oracle 11 g (need help)

  Hello guys,.

  I am a developer Oracle and prompt to convert the script to copy/clone oracle 9i and oracle 11g db. (without using RMAN)

  I spent using oracle9i db scripts and the steps are as follows

  (1) the control of the script file creation
  ALTER database backup controlfile to trace noresetlogs

  (2) creating the LINK for udump, cdump and bdump

  LN - sf/apps/oracle/diag/rdbms/SOURCEDB/SOURCEDB/bdump/apps/oracle/admin/SOURCEDB/bdump
  LN - sf/apps/oracle/diag/rdbms/SOURCEDB/SOURCEDB/cdump/apps/oracle/admin/SOURCEDB/cdump
  LN - sf/apps/oracle/diag/rdbms/SOURCEDB/SOURCEDB/udump/apps/oracle/admin/SOURCEDB/udump
  (2) take the info from the data path files in a file of source db
  Select file_name in sys.dba_data_files
  Union select sys.dba_temp_files file_name
  Union select name from v$ controlfile
  Union select Member from v$ logfile;
  (3) TURN OFF THE SOURCE DB
  (4) amending the control file

  CREATE CONTROLFILE
  ....
  LOGFILE
  DATA FILE
  RECOVER THE DATABASE
  -Database can now be opened normally.
  ALTER DATABASE OPEN;
  (5) changing the queue (STEP1) control replacing the SOURCE db DB TARGET
  Change the file data (from step2) 6) and copy of the DBfiles in the new location
  (7) COPY init.ora, init_batch.ora, init_tp.ora
  (8) run the file control (created from step 5)
  9) creating the LINK for (TARGETDB) bdump, cdump, udump
  LN - sf/apps/oracle/diag/rdbms/TARGETDB/TARGETDB/trace/apps/oracle/admin/TARGETDB/bdump
  LN - sf/apps/oracle/diag/rdbms/TARGETDB/TARGETDB/cdump/apps/oracle/admin/TARGETDB/cdump
  LN - sf/apps/oracle/diag/rdbms/TARGETDB/TARGETDB/trace/apps/oracle/admin/TARGETDB/udump
  (10) CREATE TARGETDB TO SPFILE
  (11) START UP targetDB

  Fortunately, I ran the same script for ORACLE11G it works and DB is also copied to 11G.

  Team,

  What worries me is... same scenario for 9i works very well in 11g means what's the features I can include for 11g (what I might have missed)

  NOTE: WITHOUT RMAN

  Please suggest.
  Oracle 11g backup/cloning is the same as 9i as steps above. ?  Please suggest I can include measures to which has the advantages of 11 g. (without RMAN)

  Please Guide

  It gave me 10 days to complete the script. I can't give the same script for the management team... I'm worried.

  I will include 11 g features in the script after that copy DB is finished.

  Please highlight from DB 11g features I can include

  Thank you

  S

  As mentioned earlier, all or the features to be added depends on many factors i.e. you have the use of this feature, are you allowed to use this etc etc. If you are a developer, someone see what features you used in any other 11g of your environment. Your script should do the part of cloning. Features added in the cloned part can happen later.

• Copy/Clone virtual computers to one ESXi host to another

  Hello world

  I am new to virtualization of questions and I would like to copy/clone VMs
  to an ESXi host to another, but I don't know what is the best way
  to achieve this is.

  The background is as follows:

  • Two identical ESXi hosts (hardware/software) running ESXi v5.1.
  • An active VM (Windows 2008 R2) on each host

  The goal is to have on the host 'A' sleep copy of the virtual machine
  running on host 'B' and 'B' have a copy sunset
  on "A".

  Ideally, the copy/clone should take place without turning off the virtual machine running and
  can be automated / on demand.

  I tried to clone a virtual machine running, and it seems to work but the VM cloned
  had lost the original network configuration.

  We want that exact copies of virtual machines ready to be awakened in the case of an ESXi
  loss of the host.

  Thank you for your help.

  Hey,.

  with licensing, I meant edition, standard, Enterprise, Enterprise Plus, to see what features are available to you. If you have answered the question

  With the server vCenter Server, shared storage and 2 guests with Standard license, you have everything you need for vSphere VMware High Availability (HA)

  Your virtual machines must be running on the shared storage. If the host fails, the virtual machine running on it will start automatically on host B. If you do not need to copy clone anything because the original VM starts right on the other host.

  Downtime virtual machine in case of a crash of the host will be the time for HA to recognize the crash (a few seconds) + at the same time that the virtual machine must start to a new host.

  As long as it's a normal file based Virtual Machine then yes CCC will save it however if it is the partition Boot Camp running as a Virtual Machine of the CCC do not back up the Boot Camp partition.  For this you need WinClone.

• Copy / Clone of database on different hosts

  Hello

• Test bench - selection of material resources

  Hi all

  I use TestStand 4.2.1 with LabVIEW adapter (LV 2009).

  I'm developing a test sequence which, for the time being, works on the sequential process model and will run later on the model of parallel processes. I also develop OI in LabVIEW for this test sequence. The test involves the use of an EMS and a NISE virtual device (I preferred, so far, using subVIs NISE in LabVIEW modules rather than integrated NISE TestStand facilities).

  (1) in order to select the resources of hardware device (EMS reference, name of virtual device NISE, NISE itineraries to be connected, etc.), I have a dedicated module for LabVIEW (VI) who runs first, in the configuration section. It is followed by other modules of "Open & configure ' for each material resource, it is a basic interface (dialogue) with drop-down lists that allow the user to select resources. However, if I want to use the parallel model for 4 DUT, it will display 4 these dialog boxes; also, in each race for each object to be measured, re-displays the dialog box.

  My question is: How can I switch handles/references to material to be configured for the IO sequence I'm building in LabVIEW? Should they be passed as parameters to sequence (params) for MainSequence? The operator must select resources only once, when he starts the IO; After that everything should work without needing to select again the device resources.

  (2) if I implement the model of parallel processes, how can I access variables of each socket (running in parallel to the test sequence), etc. At this point, I do this by using the 'testbed - Get property"Subvi (from the context of the sequence and the search string to the Subvi). In the case where I have 4 outlets running, how to sequence of each socket context? Or is there another way to access the properties? (I see "ThisContext.RunState.TestSockets" as variables in TestStand... is it a clue?)

  Thank you in advance for your help!

• How to copy / clone the parental controls on another account

  Is there a way to copy or clone parental control settings of an account limited for a new account?
  I'm going to set up individual accounts for my children and I find it very embarrassing repeatedly authorized programs list. It would also be useful to have the settings for synchronization if the settings for an account (if the settings have been changed) could be copied to another account.
  Any advice or pointers will be greatly appreciated!

  Toweri,

  Thanks for the reply. You can copy a user profile, however, you must enable the family settings again. Unfortunately, there is not a way to clone.

• Copy Clone VM on the remote host?

  We currently have a Vcenter configuration limited to 3 guests.  I am creating a system for disaster, assuming that our main centre of recovery should fail.

  So, I need to program a clone of the VM are held every week - but then I need to copy this clone to a remote host which is not in the same data center, although it IS on the same network.

  Is there a way to achieve side manually remove a host to Vcenter and adding remote host (4th) whenever I want to copy?

  If I copy the clone on an external drive, I have to copy it again to the remote host.  It is 2 instances of copy on the network and which can last for hours.

  I want to reduce it to a single copy and perhaps even automate it with a script, but I don't know everything that the CLI in ESXi.

  Any ideas are appreciated.

  Understandable, I thought you wanted to just copy of VMDK but a clone first takes a snapshot of the virtual machine. This removes the lock on the base VMDK. ESXi can run rsync, but it is not supported. It is perhaps a bit over your head because you have no experience with Linux.

  http://www.virtuallyghetto.com/2011/02/how-to-compile-statically-linked-rsync.html

  What you could do is however if sure the source host and destination have access to the same storage. Then plan a clone to the virtual machine, but leave it turned off permanently. In the case of DR, on the other host, go to the data store, select the virtual machine folder, right-click the .vmx and say file added to the inventory. You can then restart it on another host. Or the DR host only has local storage?

• How copy/clone a VM without saving it powered by?

  Hello

  Is it possible (for example PowerCLI etc.) that I can copy or clone a powered on virtual machine from a data store on our vCenter to another, without going through the new clone/copy saved as a virtual machine in the vCenter? I just need a copy exact a VM under tension, but without the inconvenience of having to remove the copy of dream of the inventory.

  Thanks in advance,

  Rasmus

  Follow this path.

  Take a snapshot of the virtual machine.

  Connection to one of the ESXi where the virtual machine is running and use

• How can I make a copy/clone of an existing virtual machine?

  I have VM Fusion 2.0.2 running on my MacBook.  I have several virtual machines running, and I would like to copy them and use it as a starting point for a new virtual machine.  I know how to take a control point, but what I want to do is to create a single independent computer separate from an existing machine.  is this possible?

  I have VM workstation 6 running on a PC and I know I can do it by cloning the virtual machine, I just want to make something similar.

  Licensing issues aside...

  With Virtual Machine to stop target, not suspended...

  CTRL-click on the entry of the Virtual Machine in the Virtual Library Target Machine and select Show in Finder and closing of the merger.

  CTRL-click on the target Virtual Machine in the Finder package and select duplicate and it will create a copy of the virtual computer target package in the naming convention of "copy" and you can rename the Package by selecting and pressing ENTER.

  Open Fusion and drag and drop the Virtual Machine copied/renamed on the Virtual Machine library package to how you can change the display name of the Virtual Machine library.

  The first time you start the virtual machine copied/renamed be sure to select "I copied it".

  Note: If you are using Windows then you will need to run NewSid to change the name of the computers and the security identifier.  Also if Windows and not a VLK version, you need to activate Windows again.

• Question for users of Carbon Copy clone or Super Duper!

  If you use SuperDuper or CCC! to make clones of your system drive, you can run a little experiment for me?

  With the clone disk connected, place your FCP in the trash. Do NOT drain.

  Try to re download the app on the App Store. You get a warning that the application is already installed?

  If you do not, stop downloading and backward the app from the trash to the Applications.

  Thank you very much.

  I moved from FCP - X in the basket, with the clone (s) to the reader of the CCC system mounted.

  Went to the app store and FCP - X showed with an install button. Clicked on install and download started.

  My clone (s) have different volume names, don't know if that makes a difference.
