Thin provision NFS works only for instant VMDK

Hi guys,.

We have a host of ESXi 4.1 using NFS as a storage device. NFS is provided by the platform, Bluearc Mercury.

Whenever I create a new virtual machine, for Thin Provisioning option is checked but also gray outside. There is a line saying:

"Actual allocation policy will be determined by the NFS server.

I'll check the newly created VMDK and it's a thick disk, it consumes as much disk space I put for the disc size.

So, it makes me believe that the Bluearc Mercury does not support provisioning.

The strange thing happens after that I did a snapshot, another VMDK as server - 0001.vmdk was created, and it's the thin disk.

Someone at - it the similar problem?

Kind regards

Derrick

Showmanlkz,

On the BlueArc server, file systems are provisioned files, thin as VMDK files are created as "fragmented files".  Just a slight difference in terminology, but the effect is what you're looking for in what concerns the commissioning only the disk blocks that are actually used (thin provisioning).

If you have created a 10 GB VMDK file, but have only 5 GB of data on the inside, only pointers to these 5 GB of data blocks will be created.  Us will not pointers to blocks of empty data.  Standard orders will make reference to the metadata VMDK structure and will report on the 10 GB file.  In order for a command 'df' to show the use of real drive (5 GB), rather than the allocated size (10 GB), you must enable the "true fragmented file" mode.  Contact the BlueArc TAC for the real run command.

Snapshots are a completely different beast.  By default, they are only pointers to a point static instant copy.  However, if you use our new feature JetClone to create clones in entry level file, these files will be also thin provisioned, only as the clone diverges in content data from the original VM has been created between more and more.

  • EPMA works only for IIS?

    I used asked the same question before, and I think EPMA works only for IIS, but I want to use IIS and Apachy, and apachy is for most services, IIS is only for server size, for the configuration, I lost my way, should I need to set up manually? Now, I have confirgure EPMA with Apachy without IIS, a service does not start, please notify.

    I think you're getting confused with Apache and IIS. EPMA don't use Apache, it uses a combination of weblogic (if it's the choice application server) and IIS. Uses of the EPM parts on IIS are installed automatically, you have just to make sure you have you upward and running .net and .net enabled in IIS.
    Apache is used as workspace server plugin, IIS can also be used as a plugin.

  • ListView - multiple selection works only for StandardListItem

    Hello

    In the meantime, this ListView object are less contraingnant to use; I modified my UI to work as an example of application of Battambang.

    But I have another question

    I use a GridListLayout (such as sample app stamp collector) and my ListItem is a container custom instead of StandardListItem.

    Unfortunately multiselect Manager works only with StandardListItem

    In my case, the context menu is empty!

    RIM is able to provide a sample of collector of stamps with GridListLayout? and multi select Manager / work context menu? and to highlight the points of stamps feature works in multi selection mode?

    Nicolas

    Indeed, the DeleteActionItem is not visible all in Multi Mode. I also tested is not serious if it is set with GridListLayout or not and even deleteAction.enabled of adjustment.

    I have raised a question of public affairs to do this, https://www.blackberry.com/jira/browse/BBTEN-173 so, please vote for it when you get a chance.

  • Exchange 2010 - is thin provisioned supported or only zeroeager?

    It seems to be conflicting information anywhere on the internet.  When configuring storage for the newspapers and the Exchange databases, disks must always be zeroeager or are provisioed thin discs supported these days in VMWare?  MS say this extension dynamic disks are not supported, but which is under Hyper-V

    See attached PDF.

    Q: are there requirements around storage for my virtualized Exchange solution design?
    A: VMFS on iSCSI and Fibre Channel storage is supported, as are the physical maps and virtual-mode raw device. The use of thin provisioned disks or network - storage devices is not supported by Microsoft for virtualized Exchange deployments.

  • Control/sleep of PL/SQL loop works only for expected less than 90 minutes

    Hi all

    I was wondering could someone help me. I've written a procedure that checks to see if a condition is true, and if it ends successfully. If the condition is not true he sleeps for a minute and then try again. If a time-out value is filled the procedure raises an error. This timeout is passed into the procedure in a few minutes.

    My problem is that the procedure only works if the smaller numbers are passed. I tested with success in 1,2,5,10,20 and 30 minutes, but if I spend 90 minutes it is regularly indefinitely (I let it run for more than 2 hours before killing him).

    CREATE OR REPLACE PROCEDURE proc_wait_test (p_minutes_wait, INTEGER)

    IS

    var_start_date DATE: = SYSDATE;

    var_check_result NUMBER: = 0;

    BEGIN

    WHILE TRUE

    LOOP

    -fake check which returns always false just to test the concept

    SELECT count (*) INTO var_check_result FROM DUAL

    WHERE 1 = 0;

    IF (var_check_result > 0)

    THEN

    EXIT;

    ON THE OTHER

    IF (SYSDATE > = (var_start_date + (p_minutes_wait/1440))) THEN

    RAISE_APPLICATION_ERROR (-20000,' procedure has expired, waiting specified limit of ' | p_minutes_wait |) "minutes exceeded.");

    END IF;

    END IF;

    DBMS_LOCK. SLEEP (60);

    END LOOP;

    EXCEPTION

    WHILE OTHERS THEN

    lift;

    END;

    The procedure is designed to integrate into an existing solution, so I can't change the basic features. Database version 10.2.0.2

    Thank you very much in advance for any help.

    Hello Steve,.

    We have this kind of question here: Firewall silently kills idle connections more N minutes (and when there is a high load on the firewall, the "N" decreases aggressivly).

    In the "Workaround", we used "DCD" (dead connection detection) as clients of the server pings on the side of all the N minutes (we use 10), the original purpose of the CR is to interrupt the session side server if the client is gone. but we are interested in a "side effect": This causes a part of the network traffic it is enough to "cheat" the watchdog of firewall.

    Very easy to implement: the server side, in sqlnet.ora:

    SQLNET. EXPIRE_TIME = 10

    (active next time the other is started)

    vSphere 5 is backward compatibility with vSphere 4.x, which means that you can still manage and exploit the features/capblities of vSphere 4.x using the vSphere SDK 5. However, the features/capablities in vSphere 5 are available only if you have a vSphere environment 5 as the DRS of storage for example.

    File server is 2012R2 (not... simple DFS share.)

    BUT: if I connect to another virtual computer:

    -After a restructuring or

    -After logoff / log then on another virtual machine... because i ' ts floating pool or

    -in another virtual machine in another pool with the same configuration (pre-production)

  • Why DVD players does not work? Indeed, DVD player works ONLY playback,... but doesn't work NOT to the write/burn any DVD/Sony and Memorex, etc..

    Hello:

    DVD players, both came with the PC and MSI DVD - Rom I bought through the Internet works ONLY for playback of CD - r and DVD - r, but the two do NOT write/burn brand new DVD and CD - R, popping up in the middle of the screen,... Please insert the blank in the E floppy when I actually inserted in the DVD drive.

    I have uninstall and rebooted the PC, in the hope that readers DVD works OK,... but nothing helps.

    Wonder if the registry damaged for DVD player, or what other problems causing this problem?

    Any help on this would be greatly appreciated.

    Hello

    Have you checked if the CD/DVD drive you purchased is a recordable disc? If this is the case, there should be an indication (e.g., CD-RW/DVD-RW). You can also check for the indication Device Manager.

    If you have confirmed that it is indeed able to write on the discs, then try to activate the IMAPI. To do this please see the instructions below.

    1. click on start

    2. click on run

    3 type "services.msc" (without the quotes)

    4. in the window that opens, you select IMAPI

    5. right-click on it and select "Properties".
