Suspend file systems?

I have two questions about this:

I saw that there is an option when you perform screenshots instant, is recommended to do? Will it have an impact on performance on the virtual machine?

Could "suspension" we do otherwise? In Vmware official course (ICM) there is a note that all i/o should be suspended by cultivating a VMFS volume. Is that correct and if so, how are you?

> I noticed that there is an option when you perform screenshots instant, is recommended to do?

Yes of course. It forces the OS invited to write all the disk drive caches, so you won't lose data.

> Will it have an impact on performance on the virtual machine?

Quescing happens when the snapshot is taken alone, so it does not affect overall performance.

> Could "suspend" to do otherwise?

Yes, e.g. Veeam Backup supports filesystem quescing via VSS instead of VMware Tools. And it saves me really, because one of my DC suddenly started refusing to take snapshots of suspended (reported in support).

  • VM snapshots - select memory and suspend file system?

    Hello

    What is the difference between taking a snapshot of a virtual machine, including memory vs take a snapshot of a virtual machine and standby system files only (and not the memory)? I know that to get a snapshot consistent application, to suspend the file system (which commits all pending writes in memory on the disk), but what is the difference between that and just take a snapshot of the virtual machine and including his memory - are they not the same thing?

    Thank you

    Steve

    They are not the same.

    Correct your understanding of the file system option.  By also preserve the memory, the State power of the virtual machine is also well preserved (think of it as sleep your laptop) - memory is preserved intact in the virtual machine as well.

  • standby of the comments file system create two snapshot files

    Why would or should suspend the comments file system create two snapshot files.

    In our environment, we have the following VMDK.

    Syntest.VMDK

    Syntest_1.VMDK

    Syntest_2.VMDK

    Syntest_3.VMDK

    Syntest_4.VMDK

    When I create a snapshot that suspends the comments file system it creates two syntest_1 - 000001.vmdk and syntest_1.000002.vmdk (as well as all of the files for snapshots).  Here is a screenshot.

    syntest.png

    Why and is at - it something wrong?   I can find a ton of articles on stereotypes, but nothing that speaks.

    We are currently on ESXi 5.1.0,1157734.

    Thank you

    Mike

    Out of curiosity. Are two snapshots created even when you create the snapshot manually?

    With backup applications, this behavior is not uncommon. The first snapshot is created for the virtual machine write them changed data, while the current is/instant backup, and the second snapshot is created by the backup software to attach the virtual disk basic to the host/proxy backup as "independent - not persistent. Once the virtual disk is disconnected from the proxy the second snapshot will be discarded and then the first snapshot will be validated for the basic disk.

    CBT information should not be reset somehow, but updated as changed during the backup data.

  • Suspension does not work with the exFAT file system

    I'm under Windows 7 Enterprise 64 and WMware Workstation 7.1.2 build 301548 on a host of 4 GB RAM machine.

    I created a virtual computer running Windows XP Professional SP3 with a virtual disk of 60 GB preallocated and cut into pieces of 2GB. RAM for this virtual machine is 2304 MB.

    All this virtual machine files are stored in a partition exFAT about 84 GB leaving 24 GB free.

    Everything works very well and fine, but I can't suspend the VM. When I try to do, I get the following error message:

    Cannot open the file 'C:\ProgramData\VMware\dndlogs\dndlog.conf': the system cannot find the specified file.

    Failed to save the State of the virtual machine. The State of this virtual machine may be registered only on a file system that supports more than 2,383 GB files.

    The underlying file system only supports files up to 2 GB.

    Do not suspend the VM.

    As exFAT supports files of size up to 16 exabytes (8 billion more than 2 GB!), for me this error sounds like VMware Workstation does not support exFAT partitions.

    In any case you know any workaround solution to suspend my virtual machine? Is really not exFAT support?

    Any help really appreciated!

    Kind regards.

    the dndlog.conf message is annoying but completely harmless.

    exFat is not completely compatible - you must disable overzealous checking file system with the line that Woody already mentioned.

    That usually works.

    If it is necessary, you can also set the directory - suspended like this

    suspend. Directory = "h:\suspend".

  • question of GSX almost full file system

    OK, I know that the gsx is old school but I am charged to keep it running. I have these two error. my hope is that someone has seen this before and know what direction I should take.

    1. temporary files for this virtual machine are stored in the directory ' / tmp/vmware-root, "which is a nearly complete file system. Please free up disk space. do you want to continue?

    Choose Retry to continue, Cancel to end the session.

    2. the directory ' / var/lib/vmware/machines/virtual uils2, 'less than 132 MB of free space. " running out of space in this directory may corrupt the virtual machine. This is likely to result in the prompt

    shut down the operating system. to envelope issues, continuing Vmware recommends you move or delete files to free up space now, after release of selected space.

    to ignore this condition until you turn off or suspend the virtual machine, select ignore.

    I did in PuTTY and carefully remove the older log files, but this is not enough. I can now run one of the two server who live on this box gsx... but as soon as I start the second swtart an i get these errors again...

  • Apple and legacy applications file system?

    Hello

    I heard that Apple will release Apple (SATF) filesystem in 2017.

    The release of a new file system has nothing to do with your applications, so they will still work correctly if you start to use it (even if you need to check that your applications are supported whenever you upgrade OS X)

  • Impossible to mount the drive external HARD under Ubuntu Linux - file system damaged and MFT

    I get the following error when I try to mount my external hard drive on my Ubuntu.

    UNABLE TO MOUNT
    Error mounting/dev/sdc1/media/khalibloo/Khalibloo2: command-line ' mount t 'ntfs' o ' uhelper = udisks2, nodev, nosuid, uid is 1000, gid = 1000, ask dm = 0077, fmask = 0177 "" / dev/sdc1 "" / media/khalibloo/Khalibloo2 "' came out with the exit status no lame 13: ntfs_attr_pread_i: ntfs_pread failed: input/output error".

    Could not open the FILE_Bitmap inode: input/output error
    Failed to mount ' / dev/sdc1 ': input/output error

    NTFS is incompatible, or there is a hardware failure, or it's a SoftRAID(4)/FakeRAID hardware. In the first case run chkdsk /f on Windows, and then restart Windows twice. Using the /f parameter is very important! If the device is a SoftRAID(4)/FakeRAID then frst activate and mount a different device under the/dev/map/directory, (for example/dev/map/nvidia_eahaabcc1). See the documentation for 'dmraid' for more details.

    It is not mount on windows either: "i/o device error".

    This is a disk with a single partition hard ntfs

    Of course, I tried chkdsk /f. reported several file segments as unreadable, he didn't say if he fixed them or not (apparently not). also tried with the indicator/b.

    ntfsfix reported as corrupted volume.

    TestDisk was able to correct a small error with the partition table by adding the '80' for the active partition indicator (only). TestDisk also confirmed that the boot sector was very good and it corresponded to the backup. However, when you try to repair the MFT, he could not read the MFT. He could not also the list of files on the hard drive. It says file system may be damaged.

    Active @ also shows that the MFT is missing or damaged.

    I tried to replace the USB cable. Has not changed anything. I tried to update the driver. Windows reported that he was already up to date. Yes, the pilot has been activated.

    So, how can I fix the file system? or MFT? or the I/o device error?
    I used the HARD drive for months. This problem started 2 days ago. I also tried to mount it on other computers, without success.

    Hello

    I'm sorry to read about problems with your drive.
    Unfortunately, I think that the question is misplaced a bit as your case appears to be the health of your rather external HARD drive that a specific problem related to Linux.

    To add clips, if the tools you use have failed to fix your drive, then I do not think that a user 'normal' forum will no longer.
    I know it's a fine recommendation and probably just add salt in your wounds: If you really care for files, do a sector backup before doing any file system / partition own modifications.
    The reason is very simple - if the tool you use has made a mistake when judging what actions are the right ones, and submit these changes, you move your goal - and fast!
    Instead of repairing, the tool can simply corrupt data even further.
    Any subsequent change aggravates the disorder exponentially.

    Judging by the details in your message, I'm sorry to say that I think your drive is defective, or at least the data is lost.
    Of course some companies will probably be able to restore it, but that normally costs a fortune.

    Unless you are willing to spend astronomical amounts of money on data rescue, so I suggest to accept data loss and look at what you can do with the HARD drive.
    Try to format. No problem, this indicates the drive is defective and must be replaced.

    Sorry for so little help.

    Each time an SDXC card is inserted, the action cam uses the format instead of the format FAT32 exFAT. In fact, the device to which you connect the cam action (more an SDXC card inserted) must also support exFAT file system. Otherwise, the action cam / card will not be read correctly.
