Expanding an Array - fact or fiction?

I have an XServe RAID with 7 drive modules. 5 of the bays are active and the other 2 are serving as spares. I’ve run out of space on the original 5 and want to add one of the spares to the original raid set. There seems to be some conflicting info between what Apple is marketing and real world experience. Apple’s marketing says you can easily expand the array. The discussion boards here say otherwise. You have to expand the array first, then merge the slices, which destroys all your data on the RAID. You then have to restore all your data from your backup. Has Apple taken too many liberties with their marketing?

This was my experience when I tried to add 500 GB of space to my existing array. Making the new (empty) drives available (pre-initialization?) took a lot of time, as did expanding the array over the new drives. At first, the new space was not appearing in Disk Utility...this was rectified after the Merge Slices operation, when Disk Utility reported the correct total size of the array device. The Expand/Merge did not destroy my original data, but it didn't expand the logical volume either...I ended up with a 950 GB HFS+ partition on a 1.4 TB array device. I presume that the new space is added as "unpartitioned" space that Disk Utility will not address.
Perhaps an OS that had more robust partitioning tools (like Linux) or a 3rd Party Utility like Drive Genius or iPartition could have merged that unpartitioned space with my existing volume, but I didn't want to start getting cagey with a production server array. We just reformatted and restored from a recent back up.
I think Apple should make stable non-destructive partition editing a priority for its enterprise class tools. I spent a lot of time expanding an array I ended up reformatting anyway. I could have just destroyed the array and started from scratch knowing I would have had to restore my data and broken even overall. Why offer Expand and Merge tools if they won't work with the array's default file system? Come on Apple!
I think I've got it. The RAID can be expanded
without destroying any data, but your operating
system may not recognize the expansion without
reformatting your drive or using some other
repartitioning software. Since my host system is a
Macintosh, in order to take advantage of the larger
RAID I must reformat the RAID. Seems like Apple
should come up with some software that can do this
for you. I think the instructions for expanding a
RAID should have a notice that you may have to
reformat your RAID to take advantage of the
expansion. It's taken my system over 24 hours to
expand the array and it's not finished yet. It
probably would have been faster to delete the array,
create a new one then restore my data from a backup.

  • Differences display Macbook versus Macbook Pro - fact or fiction?

    "There is a substantial difference between the quality of the display of the Macbook and the quality of the display of the Macbook Pro (both: late 2008)."

    whatever I have will be with me for the next 4-5 years...should I go with the non-retina because of this?
    It doesn't directly follow that you should limit yourself to the non-Retina, because it depends on how much storage you need. If the amount you need in the next 5 years is within the Retina storage amounts you can afford, then of course the Retina would work fine. Now, to work out what you would need in the next 5 years...

    Also do you think I will need 256gb or 500gb? which is more likely for me?
    We can't guess that for you, because it depends on your individual storage habits. You said you would need to store "music, pictures and word/powerpoint documents." You would need to start with what you currently store, and then have an idea of how fast you accumulate them. The numbers can vary widely depending on how fast you grow your music and photo collections, and the sizes of the files. For example, a person using a DSLR camera shooting 24-megapixel raw files will have a photo collection that grows in size much faster than someone who only stores JPEG files from a camera phone.
    I wouldn't worry about Word or PowerPoint files as those tend to be quite small. What consumes disk space the fastest is digital media: Music, photos, and videos. Especially HD videos. You can store maybe 100 Word files in the space taken up by a single music CD. A single 5-minute HD video can use up the same space as over 1000 Word files.
    Also, you will want to leave at least 50GB unused so that the system has enough room to manage temporary files like virtual memory and temp files, some of which can be rather large. If after you run the numbers you will need over 200GB or so, then you should be looking at the 500GB to avoid space issues. For most users, 256GB of total disk space seems to be enough though.

  • Order of loading Master Data - Fact or Fiction

    I understand that for loading Master Data for InfoCube 0FIAA_C01 (or any other) you should load starting from the lowest level.
    That means for every characteristic in the cube you have to check and see if any of the InfoObjects have Master Data attributes, and if any of those attributes have attributes, and so on. This quickly becomes a multi-level structure.
    Part of the tree structure for 0FIAA_C01 would look like:
    0FIAA_C01                                     
    ..........0COMP_CODE                              
    ....................0CHRT_ACCTS                           
    ....................0C_CTR_AREA                             
    ..........0ASSET_AFAB                                
    ..........0ASSET                              
    ....................0ACTTYPE                        
    ....................0BUS_AREA 
    <snip>
    So does that mean that 0bus_area should be loaded first before 0asset?
    Is this fact or fiction?
    If its a fact I am wondering what tools SAP has for determining the order of loading Master Data.

    Hi,
    My master data loads are largely in the area of HR.
    The only order I follow while loading master data is for a particular infoobject with regard to text, attributes and hierarchy - The order being text>>attributes >>hirerachy.  Frankly, I have not checked doing it otherwise.
    Across different master data infoobjects I see no need to have any order atleast in HR.  Generally speaking a master data object has data that has an independant existence as extracted from R/3 or other sources and not derived from any other master data object in BW.
    Master data as its name implies should not have referential integrity checks with other master data. 
    It would be good to know if someone has real experience to the contrary.

  • Slow burn vs Fast burn (which is better quality) fact or fiction

    Ok again I would like to know the official answer to this question because from the response last time, I'm not really confidence with the answer.
    IS IT FACT THAT IF YOU USE WAV BURNER AND BURN AT A SLOWER SPEED COMPARED TO FASTER SPEED THE QUALITY BECOMES BETTER BY PROOF?
    IF THIS FACT OR FICTION.
    SOMEONE PLEASE PROVIDE SOME LONG YEARS EXPERIENCE PROOF.

    Sorry, can't wait until someone clocks what I've said, 'cos I might be going out soon, so thought I'd write it up first...
    The difference between the HHB and the Mac burner is... nothing much. The actual tray and laser workings are probably the same in both units. The extra dosh for the HHB covers the casing, functionality and the convertors - it's basically a hardware version of WaveBurner, and we all know hardware versions cost more than software versions.
    Therefore, in my alleged test there should only be one of the four that shows any difference, and that's the real time recording via analogue. The other three, all remaining in the digital domain, irrespective of speed, should give the same results, because data is encoded in the same way, no matter how you do it. It would be interesting to see if there is any difference, but I doubt the equipment I've got would be sensitive enough to monitor it (or would allow me to zoom in and see the difference enough to post here). With that in mind, the human ear isn't going to hear it.
    The only REAL difference the speed option gives you is reliability of burning. The faster you get, the more prone it is of making an error in the burning process, but this can sometimes come down to the quality of the disc itself. Not all discs are the same, as I guess most people have realised to their horror at some point (data).
    Just a final note. I'm working with a voice-over artist for TV and radio, and the stations are happy to receive the files as MP3's via email. Who'd have thought that would happen when MP3 came out?!? Just goes to show people are putting a perspective on the quality standard for final use. But I'm still sending AIFF files though, MP3 makes me shudder as an original! And here we are worrying about CD quality...

  • Expanding an Array and the volume

    As of now it doesn't seem possible to expand an array and the associated volume without reformating the entire array. Does anyone know of any work arounds?
    I added a new drive to an array. RaidAdmin sees that the array is now 1.46 TB, but the Mac OS X server 10.4 that the xraid is attached still sees 1.09 TB
    Are there any work arounds for this? Or any hope of OS X upgrade that might resolve this issue? Whats the use of an expandable array if you need to copy off all data, back it up, and then reformate in order to expand a volume.
    From apple.com/support
    http://docs.info.apple.com/article.html?artnum=301443
    "At this time, Mac OS X and Mac OS X Server do not recognize the capacity of an expanded Xserve RAID until after the expanded volumes have been reformatted."
    thanks for any help

    I'm pretty sure you can expand the array and merge the slices without losing data.
    However, it would be absolutely foolish to do this without a full and proper backup. And in that case, I would strongly... STRONGLY... suggest that the best approach is just to dump the 4-disk RAID 5 and create a new 7-disk RAID 5. Faster and easier, and the OS won't have any problems recognizing or growing the volume... like it might with a volume you expanded.

  • Expanding an array

    I have expanded my RAID5 array... with one disk more...
    After manay hours thge result seems to be OK!
    But to finalize (complete) this I read on the documentation: "... select slicing, and merge the slices on the array vtaht you just expanded..."
    When I do thant "Advanced->Slicing" and I select this operation... A warning say to me that this action erase the entire Array (not just the disk merged)...
    Is this right?
    NB: Before to do do an expansion, I have tell to my favoirite apple support "can I expand an array without looose data? The response was..
    Modifying a RAID Array
    Once a RAID array is established, you can expand it by adding one or more drives to it.
    Expanding an array preserves the data on the original array. Be sure that your file
    system supports expansion. See “Expanding an Array” on page 38 for details on
    expanding an array.

  • Antivirus - fact or fiction?

    For those of us newer to OS X from PC's - do we actually need antivirus on OS X?
    Broad question but if using a solid router that is properly configured and tested, wireless with WPA and good comon sense on Internet and for file downloads, why would I need it?
    I always hear that so few if any viruses exist for OS X that antivirus is not really needed. I use my MBP at home and not on a corporate network, no open wireless hotspots or networks and am very careful about surfing and downloading files only from trusted sources.
    Obviously antivirus is always good but is it really needed in OS X?

    Also, to set the record straight, the argument that Mac users are not the target of attack because of "security through obscurity" is hardly a point you can attribute to my prior comments. On the contrary, the fact that the underlying OS for the Mac is publicly available means that anyone can review the code directly in an un-obscure and open way.
    The concept of a virus writer targeting a larger audience in the PC world holds true regardless of whether you are believe the 5% figure, or the 10% OSX adoption figure.
    The argument that one does not need anti-virus software in a world where so many computers touch the Internet (known to be a bad neighborhood) is similar to one who says they don't need to use protection because their country has less incident rates of HIV.
    Our world is a dangerous one, whether or not you use a Mac or a PC. Happy reading!

  • Fact or Fiction: Caching PreparedStatements implies better performance?

    Hi,
    I've read a number of sources that claim the caching of PreparedStatements
    (on the client) leads to better performance because it eliminates the
    overhead of parsing the statement each time the
    Connection.prepareStatement() method is called. I tend to think that this
    claim is largely database server dependent and to a lesser degree JDBC
    driver dependent and I wonder whether any noticable benefit would be gained
    on databases such as Oracle, SQL Server, or Sybase.
    Oracle already caches SQL statements and associated query plans on the
    server to minimise the amount of parsing. It does this on a server wide
    basis so that ALL connections/sessions can benefit from the previously
    parsed SQL that is being executed. It also does this independent of the
    client technology that is being used (ie. Java, PL/SQL, C++, Perl, etc.) and
    has done so long before the introduction of JDBC. Why the need to cache the
    PreparedStatements on the client if they are already cached more efficiently
    on the server?
    I would be surprised if any parsed representation of the SQL (ie. the query
    plan) existed within the client side at all, as query plans tend to be
    dependent on how the data is stored and indexed, hence closely related to
    the schema (not the client).
    I would be very interested in reading other peoples comments on this and I
    am especially interested in seeing any performance data to prove that
    caching PreparedStatement objects actually does lead to better performance
    and is not just a myth.
    Regards,
    Craig.

    Hi. You are correct that the benefit of a prepared statement cache will vary,
    depending on how the driver and DBMS interact with prepared statements,
    as well as how the application uses pooled connections. In a best case scenario
    where the application has a small set of frequently used statements, to Oracle
    (in spite of the fact that Oracle does some query caching anyway) we have
    seen and customers have reported 10-40% performance improvements.
    Oracle/OCI cursor retention is a possible reason. A worst case scenario
    might be an appliaction that makes lots of unique prepared statements from
    user input in such a way that alters the query plan, using our driver to MS
    SQLServer, a cache would be useless, and might even hurt a little. This is
    because the cache might never contain a statement for the current SQL, and
    searching would slow things down, and our MS driver doesn't implement
    PreparedStatements in a way that has the DBMS caching anything ever, so
    everything is sent for parsing like fresh SQL for every execution. Other
    more recent type-4 JDBC drivers for MS SQLServer do much better
    in this regard, and would play well with a cache.

  • Fact or fiction this sampler instrument

    So a rare erase & install today gave me the chance to allow more of my limited hard drive space figuring that the Logic + instruments total package can be installed now; everything goes good except the same problem arises: most of the Exs24 instruments will not load!
    So what gives, surely you guys can tell me why a 12 string daul guit. will load but none of the acoustics will when the App supp. libraries have them.
    All was installed -the garage band stuff. Logic Sound Libr. and Bonus Sound Libr. but the same result, the instruments are there but when the sampler tries to load them it comes up with this error for a certain .aif file [i ran the file through file find in the finder checked both discs and computer but 5D xx xx.aif isn't there at all]!
    Worse this happened in the beginning when there was a complete package of both the Sound and Sample libraries in App. Support where it should be. But then the instruments wouldn't load [this was originally when i got the program after trying the same file find then i just gave up assuming this is a package that has to be bought extra and if that's the case then this fiction done run out of luck with me and maybe this is a stupid question but it's still my belief that the best things in life are free without a fee.].

  • Customer Care Pro Department: Fact or Fiction

    Is this a real dept at Verizon?
    Here is my story:
    So my daughter’s iPhone 4 was stolen. I did online chat and
    visited a store and received conflicting information regarding replacing the
    phone. I decided to call customer care to see if I could get a definitive
    answer and honestly maybe a courtesy service (i.e. extend my current contract
    for an additional two years or use an existing $300 promotional credit I have on
    one of my lines toward the non 4g iPhone 4). Basically, I did nothing but waste
    my time.
    When I called customer care and sat on hold for 5 minutes or
    more, I explained my entire situation to the rep that answered. She offered all
    the standard options of buy a new phone at full retail, buy a phone from ebay,
    buy a $300 certified pre-owned iPhone, etc… I explained that none of those
    really sounded good to me and I wanted to know if there were possibly any other
    options. She said she could not do anything but would transfer me to someone
    who could. On hold again, then explained to another young lady the entire
    situation all over again. She said something could be worked out but it had to
    be handled by another dept and she would transfer me. CLICK and then I here an automated
    voice asking for my 10 digit number which I entered. Pressed whatever digit was
    appropriate and got the “Sorry this dept is closed” message. Frustrated, I call
    back and wait through the holding period again, explain what just happened and
    ask to be transferred. I am told there is no need for that, “Just tell me what
    is going on so I can get a good understanding.” AGAIN I tell the whole story
    and we review the options and she says “Well, let me put you on hold and see
    what I can do.” She never comes back. I hung up after 45min.
    Following morning (today) I live chat and ask for a different
    number than 800-922-0204 but apparently no other one exists. Call back, another
    holding period, explain EVERYTHING AGAIN, reviewed the standard options, and
    finally was told that I would be transferred to the “customer care pro dept”
    (finally got the name of this magical place). So of course I explain it all again.
    I even mention how the very first person I contacted (via chat) said that I
    should insure the phone since it is open enrollment. “Just be sure you don’t
    file your claim on the same call “ (the live chat person really included the winky face).
    The customer care pro said that definitely should not have been advised and apologized
    for that and all of the other misinformation that I had received but unfortunately, the standard
    options are my only options. I begged and pleaded for some type of exception or
    courtesy but got absolutely nothing.
    I then offered to purchase a tablet since I am in the market for
    one anyway. I understood that I would have to pay full price for the tablet and
    place it on the existing line of the stolen phone and change that monthly
    access from $40 to $10. Then I could activate a new line and get the two year
    contract price on one of the iPhones with $40 monthly access. If I were to do
    this, all I ask is that the activation fee be waived. “That is a standard fee
    that can’t be waived.” I asked if the upgrade fee was standard and was told yes
    but it was not something I was being charged. I then explained that I have had
    that fee waived before and she responded “You can’t expect that every time and
    what I meant was I am not going to waive it.”
    And that was the straw… I will be checking into moving all of my
    lines to another carrier especially since they are now offering rebates to
    cover early termination fees.
    Sad thing is Verizon didn’t technically do anything wrong other
    than suggesting I commit insurance fraud and mention offers that are not
    generally available unless you get the right person to authorize it. Their
    customer service is just going down the drain.

    No, here's the thing.  You DO get to post your rant on the forums.  However, others get to post their opinions, too, which might not agree with yours.
    You might not think that you posted with a sense of entitlement, but let me point out where you did.
    You asked for an exception.  You didn't get it.  You stated that "Basically, I did nothing but waste my time.', which implies that you were entitled to what you asked for.
    Then you stated " I have had that fee waived before" (which likely is inaccurate because the upgrade fee is new).  And again, your request was denied to which you posted, "And that was the straw… I will be checking into moving all of my lines to another carrier "  No sense of entitlement there??
    Verizon used to allow customers to "stack contracts", (ie enter into a new one before the old one was done and roll the old one into the new one) but they don't anymore.  But this resulted in people having longer and longer contract obligations which they then complained about as well.
    Here's my two cents on things that YOU could have done to avoid this.
    1. Have insurance on the phone.  Whether that be through Verizon/Asurion, or home owner's insurance, or some third party such as Square Trade. Or accept the responsibility for not having insurance which means that if the phone is lost or stolen or damaged, the user will have to take care of it out of pocket. Taking responsibility for oneself.
    2. You could have gotten one of the Certified Pre-Owned Devices that the rep was offering.
    3. You could have purchased a used device from a third party.
    4. You could have purchased the tablet as you described and added another line WITHOUT expecting the fees to be waived.
    I get it that you are frustrated, but some of it seems to be misplaced. 
    And I get frustrated when people post their angry posts simply because their unreasonable requests/demands don't get filled.  People, in my opinion, should be reasonable and responsible which means (again in my opinion) fulfilling the contracts into which they voluntarily enter under the terms to which they agreed without expecting waivers or exceptions.

  • SEO, Fact or Fiction?

    Our company met with an SEO specialist , some of their
    suggestions were things that I had heard before and made good
    sense. Some of the other suggestions I question how effective they
    might be. I'd like to get the opinions of some other
    designers/developers. Here they are:
    1. Making the title tag the first tag in the head section.
    Above meta tags.
    2. They suggested that by naming your pages like this: Mysite
    - Home, Mysite - About, Mysite - Contact; you could actually be
    penalized by Search Engines because they see every page starting
    with "Mysite" and consider it duplicate contact.
    3. Add keywords meta tag. Everything I've read has told me
    this tag is pretty much worthless.
    I'm not saying implementing any of these suggestions would
    cause harm. I am just curious as to how much positive effect they
    could have.

    I do not. My pages usually start like this -
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
    Transitional//EN"
    http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="
    http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html;
    charset=iso-8859-1" />
    <title>Untitled Document</title>
    or this -
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="
    http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html;
    charset=iso-8859-1" />
    <title>Untitled Document</title>
    I don't see how it could *possibly* make a difference where
    the <title> tag
    is within the head region, as long as it is validly placed.
    (I guess I should be using utf-8 encoding....)

  • Latest Virus Warning - Fact or Fiction?

    Hello every one. I just read a news article from a news service here in Australia about a new virus that is hitting Skype. This is the article if you want to read it
    [invalid URL]
    I personally am taking it very serious considering the number of people I have seen in the blogs here that are talking about being hacked or their accounts deleted.
    If I am not allowed to post links like this here, I apologise...but can SKYPE confirm that this is going on and if there are any fixes for it yet?????

    Please see-

  • Screen.message - Fact or Fiction?

    I would like to know if anyone has ever heard of or used Screen.message. According to my lecturer, it is a simpler form of JOptionPane, except you don't have to import it, it's just there already. I was hoping to use it to put two text outputs in one GUI. But the lecturer couldn't even make this program work.
    I would really appreciate some help, the only condition is that answer must be simple or the lecturer will smell a giant rat!
    Thanks! :-)
    // program to ask a user their car make/model & registration number
    // import the JOptionPane class
    import javax.swing.JOptionPane;
    // start of the class
    public class CarDetails {
         // start of method main
         public static void main (String args[]) {
              String carMakeModel;
              String carRegNo;
              carMakeModel = JOptionPane.showInputDialog(null, "Please enter your car make and model:");
              carRegNo = JOptionPane.showInputDialog(null, "Please enter your car registration number:");
              Screen.message("Your car make/model is" + carMakeModel);
              Screen.newLine ();
              Screen.message("Your car registration number is" + carRegNo);
              System.exit (0) ; // terminate application
         } // end of method main
    } // end of class

    According to my lecturer, it is a simpler form of JOptionPane, except you don't have to import it, it's just there already.This is only true of classes in the package java.lang and then, AFAIK, only in the System Classloader. In a really basic test, attempting to create a class in java.lang in your code will compile fine, but result in a SecurityException for "prohibited package".
    So, for this "Screen" class to exist it would have to be part of the jre (which it is not, at least not the Sun one and if some other copmpany is providing it as such it should be reported as that is a violation of the language specs), or it would have to be part of a third party jar and you would have to include this jar on your class path, and you would have to relax your security policies to allow it (and if you are going to allow java.lang to be raped in your security policies, then you have a potentially very large problem).
    And, truthfully, I don't even know if you can change the Security Policies to allow that particular action. Even if you can though, it is definately not reccommended to do so.
