new unseen files on the shared disk (rise of 2 VM Debian)

Hello community,

I'm quite new to VMware ESXi 3.5 and I can't find a solution for my environment, although I already read a lot of threads here and looked for other sources of help.

I run 2 VMS Linux Debian and want to share my MP3 disc. The shared_mp3.vmdk was created with the 'thick' option and can be fixed on two VMS with success.

If Debian VM #1 creates new files to the disc MP3, they are not visible to VM Debian #2.

The only solution inside the VM Debian #2 is to umount SCSI 1:0, wait a few seconds and then raise it again. Of course, stop VM Debian #2 of the VI client and it starts again, makes the visible files, but both solutions are not a solution for this problem.

Can anyone provide assistance?

Do I need to install the software of protocoll sharing SCSI-2?

Thank you in advance for your help!

Here's my detailed environment:

VMware ESXi 3.5 U4 with 2 VM Debian on the same physical host:

VM Debian #1:

'big' server that processes for example the new MP3 files and converts them to lower bit rates (e.g. for my iPod)

Located within a green network behind a firewall with a write access to the MP3 disc.

LSI Logic SCSI controller 0 with root disk (SCSI Bus sharing: None, debian1.vmdk located on the local storage as SCSI 0:0)

LSI Logic SCSI 1 controller with MP3 disc (shared SCSI Bus: virtual, shared_mp3.vmdk is independent/persistent and located on local)

storage as SCSI 1:0)

(shared_mp3.vmdk has been created with the "thick" option)

SCSI1.sharedBus = "virtual".

Disk.Locking = "false".

VM Debian #2:

UPnP streaming server

Located inside a red network with read access only on the MP3 disc. Debian Linux get the MP3 drive read-only.

LSI Logic SCSI controller 0 with root disk (SCSI Bus sharing: None, debian2.vmdk located on the local storage as SCSI 0:0)

LSI Logic SCSI 1 controller with MP3 disc (shared SCSI Bus: virtual, shared_mp3.vmdk is independent/persistent and located on local)

storage as SCSI 1:0)

SCSI1.sharedBus = "virtual".

Disk.Locking = "false".

iSCSI would push you in the same boat that the shared disk.  Two are block-level and will need you to have some sort of awareness of the bunch to them.  If you have only an ESXi host, you can create an internal network only for the two to speak to GFS or OCFS2 vm.  If you have more than one ESXI host, then you can consider a cross-over for both servers, or even a hub/switch only for the private network. You can run GFS on the same network as the usual traffic, it is not "necessary" to have a private network, comes to recommend, and it's only for server coummunication between them.  You need to open ports so that it goes to your vm.

  • Problem writing files in the shared documents directory.

    Hello

    I'm new in the development of the PlayBook. I am trying to create an application that can save image file within the shared documents directory (so another image viewer application can find). Here is my code:

    var file:File = File.documentsDirectory;
    /////////////////////////
    Try to write a file...
    var jpgEncoder:JPEGEncoder = new JPEGEncoder();
    var jpgData:ByteArray = jpgEncoder.encode (bmp);
    file.addEventListener (Event.COMPLETE, onFile_SaveComplete);
    leader. Save (jpgData, filename);

    I got a file save dialog box when I call «file.save (...)» However, once I typed in the name of the file to save and press the 'OK' button, I got the exception like below:

    Error #2044: Unhandle IOErrorEvent:. Text = Error #2038: file IO error.

    to flash.filesystem::File$/getFile()

    to flash.filesystem::File$/get_documentsDirectory()

    .....

    .....

    The same code run perfectly on my desktop, so I wonder if there is some other restriction in OS PlayBook to stop me from saving the file in the shared document directory? So, should I sign my application with certificate?

    [I read the document and understand that 'File.documentsDirectory' must be writable...] May I have I'm misunderstanding... ? ]

    Best Rergards,

    Hey,.

    Welcome to the forums! This has just been discussed in a previous thread of yesterday. Basically, file navigation dialog boxes are unfinished and lead erros weird whenever you try to use a method that requires a browse dialog box. work around right now must use the FileStream class to write your files on the hard disk of the playbook, until all the dialogues are fixed on the platform.

    Here is the link to the previous thread. inside, you will find the work around the code that you can adapt to your needs. also, there is a little more explanation:

  • use a hard file as a shared disk between two vm

    Hi guys,.

    I wanted to know if there is a possible way to create a hard file as a shared disk between two virtual machines.

    That's my idea:

    I want to create a mscluster between two vm one before I need to a shared disk - I don't want to use the external storage, so I thought that maybe there is a way to use a file hard like a disk storage shared "external".

    Is it possible to do this? If there is, I enjoy an explanation how to do that.

    Thank you very much

  • Remove temporary files from the local disk c/documents and settings/user/localsettings/temp name

    Remove temporary files from the local disk c/documents and settings/user/localsettings/temp name

    By definition, this folder should contain only the elements you don't need.  If I understand correctly, this temporary folder is a place where temporary files are stored during program facilities and the facilities.  However, I have seen references other sites to help saying some programs can store folders and files.

    I do my own temporary file elsewhere, name it accordingly and move all the files in the temp folder to the new folder. Use your computer normally for a while, and if nothing complains about missing files, you have a good indication that none of the moved files are important and should be safe to delete.

  • Problems downloading new CSS file to the title track, known for 3.1.2 bug. ?

    Hello

    I'm under APEX 3.1.2. and met some problems on download of CSS.

    I had a CSS file for an application running.
    This file I deleted and use the Create button in the shared components > Cascading Style Sheets > create a cascading stylesheet to upload the new CSS file under the same name.
    Later I tried to use some of the newly introduced classes, but they did not come to work when I run the page.

    Everything worked fine when I download the new file under a different name.
    So, it seems that the changes in the document had no effect.
    When I edited the file online new classes did not work also.

    I tried to find out by searching the weather forum and the release of notes it is a bug known to this version or not.
    Anyone of you knows?
    If it's a known bug, it is resolved to a later version?

    Best regards, Tine.

    From what you described, this could just be a problem with your browser, the CSS implementation in cache and not to pick up the update.

  • CANNOT write to files in the shared folder of XP on a PC running windows 7 - but good vice versa

    I have a laptop under Windows 7 (SP1) and a desktop running XP (SP3).  I have connected both via a wireless network. While I can see and access shared files/folders from one computer to the other computer, I can only read/write files in the shared folder on the portable computer that is running Windows 7.

    If I try and change a file in the shared folder from the PC under XP on my laptop, I get the message "this file is set to read-only. Try again with a different name "."  I know that the file is NOT checked for read-only. When I change the name of the file I get the error message "\\Desktop\SharedDocs\filename.doc you are not allowed to save in this location. Contact the administrator for approval.  You want to save in the folder my documents instead? "If I save the file to another location on the laptop under Win7 it save then OK.  I can not just save a modified version of the file in the same shared folder from desktop running XP.
    It seems that it must be something to do with permissions and access to the parameters of the desktop running XP but I can not find these. Fairly easy to find in Windows 7.
    Finally, I don't have a login/password set for the connection to the computer to Office XP.  I don't have a user name and password for the laptop Win7 but you have turned off password protected sharing.
    Anyone have a solution to this?
    Thank you

    OK - the problem is now resolved.

    I noticed that the read-only for the shared folder has been checked. When I unchecked it and also checked the box "allow network users to change my files" in the shared folder properties/sharing, I was able to modify and save files in the shared folder on my laptop.
    It's a little weird because I thought I had done this the other day where the results have been less successful.  Strange.
    Thanks for your help.

  • I can see other computers on a network of peer to peer windows XP but cannot access their shared files and the shared printer.

    I can see other computers on a network of peer to peer windows XP but cannot access their shared files and the shared printer. The computers are connected by a switch, fixed IP addresses that are correctly configured and point to a DNS server outside the network. When I try to open the icon for one of the computers, he asked for credentials. I try to type the user name for the computer that is sharing the resource and the password. It is the user account whose computer is loged on and belongs to the Administrators group. for example: user name (Computer1\username) password (password). It does not work. The Windows Firewall is disabled on all computers. It worked well there 2 days. I can't find anything wrong with the network settings. Does anyone have a solution? Thank you.

    If the portion of the machine has activated - Simple file sharing (i.e. it is XP Home or it is XP Pro with Simple (default) file sharing) - while all file sharing connections authenticate as user 'guest '.  It will not matter what username / password you provide, it will attempt to authenticate as 'guest '.  If the guest user has received a password or the guest account is not active, you will experience the symptoms you describe.

    If the serving machine running XP Pro and Simple file sharing is disabled, then you should be able to connect by specifying the user as computer\user and the password to connect.  To turn off Simple file sharing:

  • Workgroup Windows 7 - can see the folders, but not files in the shared directory

    I have three windows on the same workgroup machines (2 machines Windows 7 [A, B] and [C] XP machine). I have a shared folder on the [A], with many subfolders. When I created first the part, [B] has been able to see all files and folders in the shared directory on [A]. Next, I added several subfolders on [A]. Now, [B] can see new subfolders but not the files in the breast. Why is that happening and how can I solve this problem?

    [A] and [B] are capable of full access to the shared folders on [C]. The permissions on the shared folder on [A] are set to "Everyone" + read/write. I tried several reboots of each machine. Hit "Refresh" on [B] does not make the files appear. It is not password-protected. It turns out that [C] has exactly the same problem as [B], that makes me think there is something to do with the share on [A], but I can't understand it.

    On [A].

    Under sharing advanced > caching, I chose only "the files and programs that specify users are available in offline mode."

    Under [advanced sharing] > permissions, "Everyone" is given full control, change, and read them.

    Under [advanced sharing] > permissions > Add > locations, machine [A] is visible, but are not machines [B, C].

    Any thoughts? Thanks in advance!

  • Sansa e280v1: impossible to find new music files in the player

    Hello world

    I am not fond of new posts, but I've tried various searches and couldn't find any satisfactory results...

    Recently, I tried to put the new music files in my Sansa (mp3 format), as I often do. There is already a good load of songs but enough remaining space. The problem is that the files into the device without any problem, but when I unplug, after the database update, music files would not appear in any of the categories of music (artists, albums, songs, etc.).

    I checked the labels so that they all ID3v2.3 ISO-8859-1. Yet, after a retry, same result: the files are on the memory of the device but not recognized as music files.

    I tried to erase some previous files and put back them: even. New music (.mp3 or .wav) file seems to be not recognized as an audio file by Sansa.

    Can someone enlighten me, please? given that it is very frustrating...

    The firmware is 01.02.15J (purchased at the Japan)

    Sansa e280 v1.

    Thanx

    Ben.

    Well, guys, the solution was much simpler way.

    I do not format disks (always fear of losing important data in the process) so I asked questions about another solution before trying this one, but, as shown in the rest of the story, that's what I had to do.

    I just format Sansa, the new version of the firmware in it. Files with whom I used to have problems reading perfectly now. So I guess the problem might come from files may be corrupted, I had on the player beforehand.

    Anyway, thank you guys for your guest to support!

  • Cannot open the files from the shared network drive

    Hi, I am trying to open a file located on a server of storage attached to the network in a shared drive. When I try to open the file in Photoshop CC 2014 directly or by double-clicking in the file Explorer, I get a pop-up box in Photoshop that says that the image of CR2 is not the right kind of document. If I copy the file to another USB drive attached, the file opens correctly in Camera Raw.

    This will give you tangentially more insight in the work through a network to NOT be supported by Adobe:

    This is the standard text often used for saving to a network (NOTE the part where he explains that normally, it works, but it is impossible to solve someone else on the network remotely, and that's why he didn't is not supported by Adobe):

    If you open files on a network, or saved on a network server, please cease and desist immediately in the case where you currently have problems with one or more files. On a network is not supported.

    See:

    http://kb2.Adobe.com/CPS/406/kb406793.html

    Copy the local file CLOSED your server hard disk, work on it, again to save it on your local hard drive, close it and copy the closed file on the server.
     
    Of course, the fact that Adobe does not support work on a network does not necessarily mean that it doesn't work.  It should be.

    Adobe position is that there are too many variables in a network environment for them to ensure that everything will work properly in all systems, particularly in view of the fact that that something will not work properly, it is probably the fault of the network, and Adobe has no way of troubleshooting of your network.

    If you are unable to work locally, you are yourself, and if something happens, you're on your own. If you work from a server, make sure that your network administrator is a competent professional.

    When problems arise, much valuable work can be lost.

    The feature that you want to use is specific FP10, to access, you need to include the playerglobal.swc of FP10 in your construction. FlexBuilder should do this automatically if you go to project-> properties-> Flex compiler and "Need Flash Player Version" value 10 or later.

    You can find versions 9 or 10 playerglobal.swc in "\frameworks\libs\player\". If I remember correctly, the first version of the SDK supported by FP10 was 3.2.

Maybe you are looking for
