Share local storage

Hi,
According to the online help:
Note
In Oracle VM, sharing a local physical disk between VMs is possible but not recommended.
Can someone know how to share a local storage device ? Because it is something I would like to test ;-)
Thank you,
Yacine

My physical disk is in fact a SAN LUN (but need a third party driver) which explain why I want to share a local storage with all my OracleVM dom0 (all of them can see and have access to the LUN) and store my guests VDI on it.If you're using a SAN LUN, this is not local storage, it's shared storage. Oracle VM will automatically format this with OCFS2.
I'm not familiar with ASM but correct me if I'm wrong it is "just" a volume manager (like LVM2) ? Could I use ASM like I use LVM2 with my Xen/KVM open source installations : I mean create a LV for each guests VDI and avoid using a cluster aware FS (like OCFS2) ?ASM is used by Oracle Database for data storage. It is both a logical volume manager, a redundancy engine and a filesystem. It cannot be used outside of database. You cannot use ASM for Oracle VM. You also cannot use LVM with Oracle VM, as it is not cluster aware. You must use OCFS2 and the Oracle VM UI to configure an Oracle VM pool.

  • VSphere 6, can't use FT with local storage

    Hi guys,
    Now that I have figured out that when turning on FT without shared storage results in no datastores being shown in the FT dialog box in the web client, I've run into a different problem (thus the new discussion topic).
    When I turn on FT for a VM that is on local storage, I am now able to select the datastores, but when I select local storage for the secondary VM, I get a bunch of errors that tell me the secondary host can't reach the .vmx file (of course - that's why I needed the shared storage - for these little files). Shouldn't FT be copying the .vmx file and whatever else it needs to be shared to the right spot, since I've told it where that is? Do I need to move my VM to shared storage, then move my VMDKs and stuff to local storage manually?
    Here's a screenshot of the dialog:
    Here's the current hardware setup:
    ESX1:
    - IP: 192.168.220.51
    - Datastores: ESX1-LocalStorage and NFS
    ESX2:
    - IP: 192.168.220.52
    - Datastores: ESX2-LocalStorage and NFS
    My primary VM for FT is on ESX2, and trying to get my secondary on ESX1.
    Thanks!

    The availability guide isn't accurate (I'll work on getting it corrected). The requirements for FT storage are:
    - Shared storage: FT config file, tie-breaker file, primary VM vmx file
    - Local storage: all other files (VMDKs, etc).
    The limitation with this however is that FT can't move or replicate your VM files to a new location, so if the host where the primary VMs VMDKs are stored is unavailable FT won't be able to spin up a new secondary.
    Example:
    3 hosts (A, B, C)
    Primary VM running on A - VMDKs stored on local storage
    Secondary VM running on B - VMDKs stored on local storage
    If host A fails, the secondary on B will take over and become primary. However, until host A comes back on-line FT will not be able to create a new secondary.
    Does this make sense?
    Hi, gs_khalsa,
    That does make sense. It isn't all that I think people were hoping it'd be. I think a lot of people were envisioning setting up 2 or 3 hosts in a small environment with no shared storage, and using FT as a share-nothing setup that would ensure a VM never goes down as long as at least one host is alive and the VM isn't corrupted. It's 99% there, but the need for shared storage (that is presumably HA storage, since we don't want the storage to be our single point of failure) for 3 little files kills the vision. FT not being able to spin up a new secondary on a 3rd host seems like it could have been done, too, since FT obviously knows how - it just doesn't automatically assume it should use that 3rd host. Maybe it's more complex that it sounds to actually achieve. At least we have multiple vCPU support now, which is a big step forward. Maybe these smaller milestones will come about in sub-version upgrades *crosses fingers*.
    By the way, I appreciate your responses - they've been very helpful in understanding how what I thought the new FT was and where that idea is off target. Thank you.

  • Adobe Flash Player Settings Local Storage dialogue box

    An 'Adobe Flash Player Settings Local Storage' dialogue box has recently began appearing (since upgrading to latest version of FP) whenever I play a vid e.g. on YouTube. It gives a URL (not always the same one) and says it 'is requesting permission to share info on your computer' with two buttons for Allow and Deny. With all the recent concerns about hackers getting in on the back of plug-ins and add-ons such as Flash Player, I've been clicking Deny. Is it safe to 'Allow' and is this part of the Adobe FP software? If its not safe and my computer has been compromised, what can I do to clean my PC? Many thanks.

    You can control the way Flash behaves using the Global Settings Manager. The panel you see there are the actual settings on your own machine. Use the menus on the left to load other panels. The Help files explain what each setting does.

  • Content to local storage

    I would like to request to move our ItunesU site for mnstate.edu moved to local storage. I would like to request separate public and private content. Can you let me know the correct procedure in doing both of these requests.

    Curt, Shannon ...
    Lemme disambiguate your questions. Let's tackle public/private sites first.
    To request a public site (with a public feature page), send an e-mail to: [email protected] and ask the iTunes U gurus to set one up for you. Public sites and public feature pages are described in the iTunes U admin guide as well as here:
    http://discussions.apple.com/ann.jspa?annID=602
    "Logically" and "structurally" speaking, a public site and a private site are pretty near identical. The only differences between them are the appearance of the public site's welcome page (the "public feature" page as it's called in the documentation) and the intended use of the public site (that is, to be the place where readily-accessible public content goes). Another thing to note is that your private site and your public site share the same storage on Apple's servers (if you choose to let Apple host your content) ... taken together, they cannot exceed more than 500GB.
    Note that in either (or both) a private site and a public site, you can host content on local servers ... this is, on servers controlled by your school and not by Apple. The way that Apple manages this is that you setup RSS feeds for your content and tell Apple to link those feeds to tabs ("groups") within iTunes U courses. Apple refreshes RSS feeds every night ... so if you update something locally, it likely won't appear in a course tab until "tomorrow". However, you can force an immediate RSS refresh through the web service. Also note that the amount of content you can host locally is only limited by the amount of money your school is willing to spend on hard drives. Apple cannot request that this storage be increased because it's something internal to your institution.
    You do not need to send Apple a request to allow you to host content locally ... just go into your iTunes U site and setup a course tab. Tell the tab that it takes content from an RSS feed (by filling in the info the tab requests) and you're done.
    Hope this was helpful.

  • What is "local storage" in Safari 5.1.7

    Why is it in Safari 5.1.7 that it always takes a couple of reset Safari's to actually clear out local storage? Everything else always clears out, just local storage will pop back in ...

    Might be the security fixes >  Safari 5.1.10 for Snow Leopard

  • I'm try to buy a movie from iTunes with my I pad 3 and it tells me there is not enough local storage and when I go to my local storage there is a lot on free storage I also restarted my ipad but still the same prob what do I do?

    I'm try to buy a movie from iTunes with my I pad 3 and it tells me there is not enough local storage and when I go to my local storage there is a lot on free storage I also restarted my ipad but still the same prob what do I do?

    5GB is typically not enough space to download a movie.  Often, movies take from 3 - 5 GB to begin with.  The only option you have is to delete more things from your iPad.  You can remove unused Apps, pictures, music, text message (messages with pictures can take up a lot of space), email messages, books, magazines etc.

  • How do I download a movie to my phone?  when I click 'rent' through itunes, I get a message that there is not enough available local storage, but I can manage my local device storage usage in 'Settings'.  I have activated icloud, but this has not helped.

    I always do my Rentals with the itunes program on the computer.
    Make rental from itunes store. It will show in movies under library, DO NOT click to play it. Plug in the device to the computer. Click the name of the device on left. Click on movies. There is an  option to copy to the device. Sync. obviously you still need space on ipad to put rental but you can have it take computers hard drive space until you need it.

  • Local Storage on IPad and Iphone is missing IOS7

    Hi,
    I have a Jquery Mobile app working fine in IOS6, upgrading to IO7 on the Ipad and Iphone the app is crashing when returning lists of data that previously worked. Our app works exclusivley with the local storage code in all modern browers allowing offline usage. Seems like the IOS7 upgrade is disrupting this somehow. I
    cannot see the Local Storage icon in the web developerm, I am expecting this.
    I can load around 40 list items into JqueryMobile, after that Safari crashes and the Wed Developer disappears. Any thoughts welcome.

  • HT4191 iPhone Local Storage "My iPhone" - How do you create this folder for use by the Notes app on a iPhone or iPad?  If I want to keep some notes only on my device and not in a cloud environment associated with an e-mail account.

    iPhone Local Storage "My iPhone" - How do you create this folder for use by the Notes app on a iPhone or iPad?  If I want to keep some notes only on my device and not in a cloud environment associated with an e-mail account.  I've seen reference to the  "My iPhone" local storage put no mention on how you create this folder or access this folder within the Notes app.  I realize storing information in a local storage like this provides no syncing between other iDevices but that is exactly what I'm looking for.  I'm running iOS7.0.4 on a iPhone 5S, and a iPad Air.  Any help would be greatly appreciated.

    If you go to Settings > Notes > Default Account you will see "On My iPhone" as the default account and the only choice if you have not enabled syncing Notes in Settings >iCloud or Settings > Mail, Contacts, Calendars. If you have enabled syncing you can still select "On My iPhone" as the default account. When you are in the Notes app you won't see any accounts listed if you have not enabled syncing because they are all in the On My iPhone account and that is the only place possible. It is not a folder that you create.

    Can I use iCloud as my library instead of using local storage?  Would I be able to synchronize the music on my phone? and make CDs out of the my music in the icloud using itunes?

    Many thanks JEM24 for your help.  Ive just spent the best part of six hundred pounds on a new Sony Rx100m2 compact camera, so I have no interest in the Ipods camera at all really. I doubt Ill be watching many videos on it as Im very lucky in that I have a good Android tablet. Its more as a stock music player that Ill be buying the Ipod for, if indeed I do end up buying one. I dont like the idea of paying the exorbitant amount added for more memory space that Apple along with most other companies charge. In fact I read an article on this very subject just yesterday in the tech section of Flipboard. It stated in the article that in the case of the Iphone  the actual cost of each additional  gigabyte of storage  to Apple et al is something in the order of 60p.. This is certainly not reflected in the price us the customer has to pay at the till.. Its for this reason primarily that Apple in particular, because their products do not allow adding expandable memory of your own in the form of cheap to buy cards, that nobody in their right mind buys the 64gig etc Iphones..I am aware that we are discussing my potential purchase of an Ipod Touch here but you see my point. Many thanks again though for helping me.

  • Safari 5.1.7 local storage not always clearing upon reset

    There are several threads through out this forum regarding cookies being accepted regardless of settings, but much of those seem to be fixed by one of the recent security updates (seperate from an actual Safari update), including fixed for me. But, have noticed that "local storage" items do not always clear out upon a reset of safari (all boxes checked). In fact, sometimes, it takes two or three resets to completely clear them out.  I have verified this behavior on several mac's running SL each yeilding the same.  I just wondered if anyone else has seen this, or has found a solution (or if this is expected behavoiur). Does this indicate a security threat within the browser?  I have used the feedback to Apple to report this.
    I did find this explanation, however:
    https://developer.apple.com/library/safari/#documentation/iphone/conceptual/safa rijsdatabaseguide/Name-ValueStorage/Name-ValueStorage.html

    BDAqua,
    Nope. It's very erratic. For example, just now I cycled several times between the inbox and the smart mailbox and even closed and re-opened. The inbox showed messages. Then I quit mail and re-opened, the inbox was empty. It took a couple more cycles of quit and re-open to get an inbox display. But as soon as I got it back on, and then closed or changed mailboxes, it disappeared when I went back to the inbox.
    Hellofa way to run a railroad.
    And just for reference, when I first had this issue last week under 10.6.8, I read several posts on this forum wherein other users had problems with the inbox display. Other than the smart mailbox "fix", I never did find a definitive solution or explanation as to why it is occuring.

  • How does one clear the Local Storage in Safari 6.0?

    I used to be able to delete the cookies in the Local Stiorage folder.  But the old path ~/Library/Safari/LocalStorage doesn't exist anymore since the system got updated to OSX 10.7.4 and Safari 6.0.  And as ever emptying the cache via the develop drop-down menue doesn't clear the cookies stored in Local Storage.
    I am totally at loss, where these cookies are hiding in my system but really want to get rid of them.  Firefox is an alternative but it is tiresome to use this browser as it keeps on blocking things I want to do or asking me a little bit too frequently for permission etc.  Can anyone explain the Local Storage issue to me please?

    hpr3, thanks for your response but you didn't read my post correctly.  I am not referring to 'normal' cookies.  The ones which are stored under the section Local Storage are special and survive the general 'clear all website data' action via Safari's preferences.  I know several people have pointed this out before me.  I was able to clear these cookies in the Local Storage folder before but it was always quite a lot of 'clicking through' to be done and one had to go through the Finder via user/library/safari/local storage etc.  I recall there was a folder involved named Macromedia as well.   But with the upgrade of the operating system and Safari this path doesn't exist anymore.
    If you clear the cookies via preferences, then click out of Privacy and back in, you might notice that even though you haven't used your web browser at all, there are still cookies which magically re-appear. And they are tagged as Local Storage.
    Now, can anyone else come up with a helpful answer?

  • IPhone would not let me delete individual song from library, tried deleting album to remove music from local storage, now certain songs from album do not show in iTunes match on iPhone only on computer

    Upon completion of matching and uploading my very large library of music (+15,000), I wanted to see how iTunes Match worked on my iPhone. I started it and selected the first album in the list to listen to. I let it play the entire album and then decided that I wanted to remove certain songs off of the iPhone's local storage. Tried to delete the individual songs and it would not let me. So I figured that I would go back and just delete the album. After selecting delete I went back to listen to one of the songs on the album and realized that it deleted several of the songs from the iTunes Match completely. When pulling iTunes up on my computer the songs are still there but does not give me the option to upload to iTunes Match.
    I have tried turning off Match on iPhone and back on (doesn't seem to do anything cause when turned off the iPhone still displays the music.)
    Then tried power cycling. (Still shows the music)
    Then I tried power cycling again and resyncing the phone and the iPhone still shows the music as it was on the phone.
    How do I get the music to be accessable on the iPhone again.. I have been messing with this for the course of 3 hours now.. and any help would be appreciated!!
    iPhone 3GS 8GB

    Actually Michael I know exactly how to delete.. The iPhone would not let me swipe to the left to delete the individual song, so I went to the album view and did it there.. The issue I am having is a bug because it removed 3/4 of the albums availablity off my iPhone.. You post proved no help because it is basic troubleshooting which, if you read my post, I have already done.. I did however figure out how to fix my issue on my own.. Basically I had to remove the album from my iTunes on my computer and upload it again to iTunes Match..

I am not sure whether the failure to compile the first file (with __thread) was due to the incompatibility of this Sun assembler. In the first case, the error msg was emitted before these 2 lines are printed.
    I further read a post about gcc 3.3.3's inability to compile code that has __thread in it, on a HP-UX 11.11: http://forums12.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1216595175060+28353475&threadId=1148976 The conclusion seems to suggest that "the 2.17 GNU assembler did not support thread local storage" and gcc sees that and thus disallows TLS.
    If the assembler is the culprit, then does anyone know whether this "Sun WorkShop 6 update 2" assembler in my installation can work with TLS? And how come a Sun assembler becomes the back-end of gcc? I read that gas (the GNU assembler) is the default backend of gcc. (How) can one specify the assembler to be used for gcc?
