Linux swap file

Similar Questions

• When the vm swap file is created?  Question of test sample.

  Have several vmware docs what state it takes place when vm powers on:

  sched.swap.Persist Specifies if the virtual machine swap files

  If persists or removed when the VM

  is turned off. By default, the system creates the swap

  file of a virtual machine when the virtual machine is

  power and removes the swap file when the virtual

  machine is turned off.

  The host creates swap VMX files automatically, so there is enough free space on the disk at the same time a virtual machine is running.

  
  

  So that's what I answered on the supplied vmware test and it was marked as incorrect, but he gave no explanation.  So when is it created exactly?

  
  

  Thank you

• Converter and Linux Swap

  Hello

  Why the converter cannot see Linux Swap partitions? I created a VM without any problems, except for the fact that it is not at all the second partition of the physical server. This is the original arrangement. Virtual MACHINE contains only the first and the third partition.

  # fdisk-l

  Disk/dev/cciss/c0d0: 146.8 GB, 146807930880 bytes
  255 heads, 32 sectors/track, 35139 bottles
  Units = cylinders of 8160 * 512 = 4177920 bytes

  Device boot start end blocks Id system
  / dev/CCISS/c0d0p1 * 1 26 106064 83 Linux
  / dev/CCISS/c0d0p2 27 1054 4194240 82 Linux swap / Solaris
  / dev/CCISS/c0d0p3 1055 35139 139066800 83 Linux

  HM, the SWAP partition is recognized correctly

  -->    
  -->     
  -->     
  -->    
  

  However, there is no volume which corresponds to this partition. Are the recognized only the volumes ' / ' and ' / boot ' (no Exchange). The swap partition is activated?

  Converter detects the SWAP partitions active file/proc/swaps by iteration. What is the result of

  # cat /proc/swaps
  

  on the source?

• Swap file UUID partition

  We had to resize our partition root on one of our 3.0.2 ESX host. In the process, our over Linux swap partition corrupted. We have restored the partition and then was re - activate the partition with the kswap command. We get always the no error of swap partition at the start of the host. I think the problem is that the specification of the UUID in the fstab file is incorrect. However, I can't find a way into ESX to list the UUID for the partitions of the host. Linux command like sudo blkid and ls-l commande┬a identifiant_volume do not work. What is the process to find the UUID in ESX swap partition, so I can correct in fstab?

  Thank you for any input,

  dumpuuid $(swapon-s | grep partition | awk '{print $1}')

• Could what harm be if the swap file is deleted manually?

  In order to better perform on the drive C: of HDD (1), I put the drive V: on HDD (2) for virtual memory.

  If I have window shutdown properly without going into sleep / hibernation, I would like to know if I delete the file manually on V: drive, what harm could it be?

  Does anyone have any suggestions?

  Thanks in advance for your suggestions :>

  so if I'm going to restore the image of the OS to the C: drive, I can delete the Page file of formatting of the partition, which keep the pagefile.  On other words, also for a long time that the window is not start, so I can format the partition, who keep the pagefile, when Windows XP restarts, and can not find file, window regenerate another page file again, it would be correct?

  Does anyone have any suggestions?

  Thank you, to all the world a lot of suggestions :>

  OK, swap file contains nothing when your computer is off. all it is is the placeholder. so it can be deleted.

  and Yes windows xp will always make a new. I tried to disable the pagefile once and he continues to make a new: P

  Even if you try to delete the page file while windows is running, it will not work and windows will tell you that it is used by another person or program.

  -Alex

  will test to see if the pagefile is spilled in hiberfil.sys hibernation occurs during or not *.

  Think about it an absolute must - manually update your drivers.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded: run DriverView - define the VIEW
  for the drivers Microsoft hide - updated those without drain in their names. (Also updated
  the BIOS and chipset drivers.)

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
  http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

  Installation and update of drivers under Windows 7 (updated drivers manually using the methods above
  It is preferable to ensure that the latest drivers from the manufacturer of system and device manufacturers are located)
  http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

  If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
  Updates, that leaves about Windows updates but it will not install the drivers that will be generally
  older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
  get new manually if you wish.

• Windows 7 does not take into account swap file settings

  I have Windows 7 Professional 64 bit installed on a system with a mirrored system disk and two disks no mirroring, including a SSD drive which is configured with ReadyBoost. Because mirroring is to the integrity of the data, and has a performance cost associated with it, I don't want any file on my system disk. Instead, I want that page files on non mirrored disks.

  So I use computer-> properties and go to the "advanced system settings" to bring up the System Properties dialog box. I click on the "Advanced" tab and in the 'Performance' section, click on 'Settings' to bring up the "Performance Options" dialog box Then I click the "Advanced" tab and in the "Virtual memory" section, click on 'Change' to bring up the dialog box 'virtual memory '. Here, it lists the drive letters and for each drive paging file options.

  I put the SSD (:)) has 'Custom size' with ' Initial size (MB): ' as 24576 and ' size maximum (MB): ' as 24576, click on 'Set'. "" "")

  I put the other disk not mirrored (b) 'Custom size' with ' Initial size (MB): ' as 24576 and ' size maximum (MB): ' as 24576, click on 'Set'.»»» "

  I put the system disk (c :)) "No paging file" and click "Set".) I also tried setting the system drive (c :)) "Minimum allowed" value of 16 MB (size initial and maximum size).)

  I get the warnings appropriate, if I didn't put "No paging file" and accept the consequences. If I put the pagefile to 16 MB on the system drive, I don't get a warning of not having a swap file.

  I reboot, to let the new settings take effect. When the system is in place, if I put "No paging file" on the system drive, Windows tells me that it has created a pagefile on the system drive, and the file is approximately the same size as the physical memory, i.e. 12 G and the "Performance Options" Advanced tab reports that "the file size for all readers of Total paging" is 12288MB.

  If, instead, I put the system drive for the authorized minimum 16 MB paging file, Advanced tab "Performance Options" reports "Total paging file for all readers size" is 16 MB.

  In any situation he always respects the settings specified in the dialog virtual memory for other readers.

  I checked that 'HKLM\SYSTEM\CurentControlSet\Control\Session Manager\Memory Management\PageFileOnOsVolume' is set to 0, and 'HKLM\SYSTEM\CurentControlSet\Control\Session Manager\Memory Management\TempPageFile' does not exist OR has been set to 0 (Windows always change this parameter to 1 if I chose "No paging file" for the system volume.) So, I change it to 0, reboot and Windows it passes 1 ad creates the 12288 MB pagefile on the system volume).

  I disabled BitLocker - it does not start.

  I don't really know what hoops I have to pass through to convince Windows to use the swap file configuration that I specify. At the very least, if I put in place minimum swap file on the system drive, to avoid the essential consequences pagination on a mirrored disk performance and to prevent Windows from automatically creating the 12 G pagefile on the system drive, I expect that the other swap files on non mirrored disks will be used by the system , but dialogue "Performance Options" it is clear that single paging file in use is the one on the system volume - exactly what I don't want.

  Can you please tell me how to get Windows to my settings?

• How to replace the SWAP file. SYS that bulky and bulky?

  Hello

  My question is how to replace the SWAP file. SYS that is bulky and bulky?

  Is it possible to "BRING" different "restore points" as separate files and reduce in size for the management and portability?:

  The simple answer to your question is no!

  Please provide a copy of your system information file. Type the system information in the search box above the Start button and press the ENTER key (alternative is select Start, all programs, accessories, System Tools, system information). Select file, Export and give the file a name noting where it is located. Not to place the cursor in the body of the report before exporting the file. The system creates a new information file system each time system information is available. You must allow a minute or two before the file is completely filled before exporting a copy.

• What to do with free mini PCIe - Flash for the swap file

  Hello

  in my T500, there is a free mini near the location of SIM location PCIe, but that's only half of length. I found an SSD at SuperTalent in these Dimensions. Someone out there who has tried to use this slot for storage, for example $TEMP or swap file?

  Kind regards

  Ronny

  It will not work. This SSD is designed for the Dell Mini 9, which uses a special type of mini PCI-e slot [FLASH_CON]. This slot machine is connected to a PATA or SATA controller on the motherboard.

  The DSS will not work on PCI-e standard minis housing because they are not connected to a PATA or SATA controller.

  I think that half height mini PCI-e slot is used for Intel Turbo Memory.

• SWAP file data store remove issue

  Hello

  I'm currently moving VMs to the data store newly created as well the datastore file swap. I have already change on all ESXi hosts, the data store were swap file will reside, however, I have still a few virtual machines on the old data store. I know not if I vMotion virtual machines from one host to another it will change the location for the swap file. My question is, can I just remove the old data store without affecting production not VMs remained the swapfile on the old location? Just try to find a solution faster than vMotion every single one of the virtual machines.

  Thanks for any suggestions or comments!

  Chris

  Hello

  As long as all hosts are no longer using the data store and the cluster is not defined using volume swapfile host (rather than storing with VM) then you should be able to disassemble the old swap partition.

  Bare in mind, vMotion/svMotion a virtual computer, you must be sure to move all the files and the virtual machine is set to store his exchange with the virtual machine files. Check that the old swap partition is no longer in use, and then take it apart. In theory the fastest way is to ensure that all VMs are defined to store swap with virtual machine files to the off and on again, forcing a new .vswp file in the same device. But it would of course affect your VM availability.

  I've seen in the past that even if the volume was no longer used by the guests, that guests required a restart until I managed to remove the old Exchange store data, just in case you meet that!

• Move the location of the VM swap file in another data store

  Hi all

  Was in a task to move the 1000 to the file location of VM swap on another data store which is newly assigned to Exchange us to the existing store database file that will be decommissioned.

  Eager to check if anyone has made movement swap of VM location of the files to a data store to another and that all measures taken to move.

  Require some VM downtime?

  Thanks in advance a ton.

  Yes it is possible without interruption of service to virtual machines.

  1. make sure that your cluster is configured to use swap data store specified by host

  2. take a host in the cluster in maintenance mode, change the location of the VM configuration file to point to the new data store

  3. do this for all hosts in the cluster

  When you vMotion a VM from one host to another the swap file will get moved to the new data store. Later when you take guests to the maintenance and return output mode, vMotion occurs for each computer in the cluster virtual and file is moved.

• Swap File question?

  Hi guys hope can help.

  I P2V had a server ESXi 5.5 using the latest VMware converter and kept the the VM Version to 8.

  When I try to start the virtual machine, I get the following error:

  Cannot create the file ' / vmfs/volumes/5391ca58-87a88951-cf0d-2c44fd8a9f40/vmx-AMLSERVER.aml.local-2469954544-1.vswp ': not found

  Not able to start VMX: msg.vmk.status.VMK_NOT_FOUND

  I have ssh would be vmfs/volumes / and run the ls command, but there is no reference to "5391ca 58-87 a 88951-cf0d-2c44fd8a9f40.

  The data store must be "53a1a9b3-d8a2c8bd-0df9-2c44fd8a9f40" because it is where lives the virtual machine.

  I tried to add the following line to the VMX file sched.swap.dir = "/ vmfs/volumes/53a1a9b3-d8a2c8bd-0df9-2c44fd8a9f40/AMLSERVER.aml.local/" but after the addition of the virtual machine to inventory even once, I still get the error above?

  Any suggestions?

  Thanks in advance.

  Nevermind I figured it

  Virtual configuration--> the location of the Machine Swap file--> change--> store of the swap file in the same directory as the virtual machine.

  This rate my troubleshooting

• Cache host / location of the Swap file

  I thought to move the files to a local SSD disk swap. My hosts are not really short memory, that I was just trying to save space on the SAN by moving Exchange out of the data store files. Is there a place any allowing the host Cache option if I move to the local SSD disk swap files?

  Evening,

  A few points to consider:

  When you say that the swap files do you have the virtual machine swap or Exchange against guests.  I would advise against the local Exchange against guests being on ssd for reasons HA.

  If you mean that the virtual machine swap file, this file is created when the virtual machine is running and is the size of the virtual memory of the virtual machine - any booking.  Put this file on ssd local has two benefits:

  1. swap because of the speed speed local ssd

  2. do not store your san (a requirement of your original question)

  Now, please keep in mind that this file is only used during the excessive demands of memory operations.  So, if you have zero on commit on the memory, they will never be used #1 do not really have an advantage.  If you find yourself with free' place san ing.  If it is essential for you, then of course do and by all means turn the swap feature to the host cache.  (Good article on it here http://www.yellow-bricks.com/2011/08/18/swap-to-host-cache-aka-swap-to-ssd/)  If you have ssd and you want to see the performance of your SSD where no more if hire you may just want to wait for 5.5 and use vSphere Flash Read Cache (article here that & #8217; s new in vSphere 5.5 storage |) VMware vSphere Blog - VMware Blogs)

  Please let me know if that answers your question.

  Thank you

  What is the best way to rate, and then place the Windows swap file?

  For the physical Windows servers, many people suggest to allocate a fixed size page file whose size is 1.5 times the RAM: does make sense for virtual machines hosted as well?

  Is there a best practice or guideline to refer to?

  As noted by A.P. the 1.5 x that RAM is really just an arbitrary number someone at Microsoft came at a time with and then walked into best practices with no real valid reason.

  However, it could be a few things to consider:

  Leave for the managed system is the easiest way, but could lead to a greater fragmentation of your C: drive.

  If the definition of a fixed size you should really consider to approve how much space you like Windows to be able to push in the pagefile with an internal memory. Usually if the machine Windows have a decent amount of RAM and page file usage is quite low.

  If adding an another virtual hard disk to the virtual computer and put the pagefile.sys on which you have a little more complex configuration, but could achieve savings if possible to exclude that drive in your backup tool and replication VM settings (if used). You could also possible to put all the files of comments VM on a sort of thin provisioned LUNS/NFS because it consumes a lot of space, but be used very little.
