• NFS share for one (1) added when adding to a new host in the existing data center

  I'm sure it's a simple answer, but I've been beating my head on the wall, trying to find a solution. The scenario is as follows:

  1 Vcenter has several hosts in different groups. All built at the same time with a NFS share that is shared among all.

  2. I add a new host to the data center (I tried independently and also added to a cluster as well).

  3. the new host sees its local disk as a data store, as expected, but I have to add the shared NFS datastore.

  4. at the level of the host, I go to configuration-storage-add storage and the NFS share.

  It shows and normal with NFS (1) as the name. I can't rename it as it says THAT NFS already exist. I understand that there are in the vcenter DB, but how to add this new host or host an existing environment and maintain the name of the NFS share? vCenter 5.5, 5.5 esxi

• For NFS Datastore vSphere alarms

  So I would like to create an alarm that corresponds to a (not state) event that fires when a NFS data store is disconnected.  I found the trigger "Interruption of the connection to the NFS server", but it doesn't seem to work at all.  Also, I would only triggers the action when the host is not in Maintenance Mode, because that would be very annoying for an outgoing call because a host has restarted for patches and generated alarm type disconnected "NFS Datastore.

• Mystery of sizing for the NFS datastore

  I trimmed a volume of 1000 GB (1 TB) on my Netapp file server and

  which exported by NFS. I have added this data store to all three of me

  ESX 3.5 hosts and migrated 18 VMs in this data store. If I add up the

  all 18 VM disk sizes, they add to 470 GB so I expect

  530GB of free space on the data store. When I look at the data store in

  the VI Client and my Netapp it shows I have 770 GB used and

  230GB of free space. The 300 GB to go?

  The pictures that were taken of this volume on my chew Netapp

  about 16 GB so it does not account for all of this space. I have

  restarted my thinking VirtualCenter server that would be a kind of

  updating of the database but has nothing done.

  Already answered on another thread, put it here also...

  Apart from the disks and snapshots, space is also consumed by the virtual machine

  swap file. County all add the size of the swap file on the Flash drive

  you will be close to amount shown by VI. The computer virtual swap file has an extension

  .vswp.

• Poor ESXi 4 NFS Datastore Performance with various NAS systems

  Hello!

  In testing, I found that I get between a half and a quarter of the e/s inside a guest performance when ESXi 4 systems connect to the using NFS data store if the clients connect to the exact same NFS share.  However, I don't see this effect if the data store using iSCSI or local storage.  This has been reproduced with different systems running ESXi 4 and NAS systems.

  My test is very simple.  I created naked CentOS 5.4 minimum installation (completely updated 07/04/2010) with VMware Tools loaded and the creation time of a file of 256 MB using jj.  I create the file on the root (a VMDK stored in different data warehouses) partition or a directory of the NAS mounted via NFS, directly in the comments

  My crucial test configuration consists of a single test PC (Intel 3.0 GHz Core 2 Duo E8400 CPU with a single Intel 82567LM-3 Gigabit NC and 4 GB RAM) running ESXi 4 connected to a printer HP Procurve 1810 - 24 G, which is connected to a VIA EPIA M700 NAS system running OpenFiler 2.3 with two 1.5 to 7200 tr / MIN SATA disks configured in front of software RAID 1 and dual Gigabit Ethernet NIC.  However, I have reproduced it with different ESXi PC and NAS systems.

  This is a release of one of the tests.  In this case, the VMDK is a store of data stored on the NAS via NFS:

  The first dd is a VMDK stored in a connected via NFS data store.  The dd ends almost immediately, but the synchronization takes nearly 40 seconds!  It's less than 7 MB per second transfer rate: very slow.  Then I get the exact same NFS share that ESXi is used to store data directly in the comments and repeat the DD.  As you can see, the SD is longer and the synchronization takes no real time (as befits a NFS share with active sync), and the whole process takes less than 10 seconds: this is four times faster!

  I don't see these results on data warehouses mounted via NFS.  For example, here is a test on the guest even running from a mounted via iSCSI data store (using the exact same SIN):

  As you can see, the performance of NFS direct comments for each of the three are very consistent.  ISCSI and the performance of the store local data disk are both a bit better than that - as I expect.  But the mounted via NFS data store gets only a fraction of the perfomance of the any of them.  Obviously, something is wrong.

  I was able to reproduce this effect with an Iomega Ix4 - 200 d as well.  The difference is not as dramatic, butalways important and consistent.  Here is a test of a guest of CentOS using a VMDK stored in a data store provided by an Ix4 - 200 d via NFS:-.

  Once more, the direct NFS mount gives very consistent results.  But using the diskette provided by ESXi on a mounted NFS datastore gives still worse results.  They are not as terrible as OpenFiler test results, but they are constantly between 60% and 100% longer.

  Why is this?  What I've read, NFS performace is supposed to be within a few percent of the iSCSI performance, and yet I see between 60% and 400% worse performance.  And this isn't a case of the SIN is not able to provide correct NFS performance.  When I connect to the NAS via NFS directly inside the guest, I see much better than when ESXi connects to the same NAS (the same proportion!) via NFS.

  The configuration of ESXi (network and network cards) is 100% stock.  There is no VLAN in place, etc., and ESXi system has only one

  Single Gigabit adapter.  It is certainly not optimal, but it doesn't seem to me to be able to explain why a virtualized guest is able to get a lot better performance NFS as ESXi itself to the same NAS.  After all, they both use the same exact suboptimal network configuration...

  Thank you very much for your help.  I would be grateful any idea or advice, you might be able to give me.

  Hi all

  It is very definitely a performance O_Sync problem. It is well known that NFS VMware shops still use O_Sync for writes little matter what share put for a default value. VMware uses a custom file locking system so you really can't compare it to a normal NFS share connection to a different NFS client.

  I have validated that the performance will be good if you have an SSD cache or storage target with enough reliable battery backup.

• Report for all the mounting points on an OS(EP OPS) comments

  Hello everyone. A hope that someone knew a work around collecting that invited all support information for each operating system. I don't know if this would require a metric Super. But in the views when I select FileServer mount I have to specify the drive and drill down to use to get these statistics for each specific guest operating system. Our report will not look very good if need to add each frame for all Linux servers in the report. And then have an empty seat if the mount is not there on the specific guest operating system.

  Come on in "group by" and select the checkbox of the columns. Then go back to the metrics selector and select a metric which is instantiated (think "space GuestOS |") C:\").. It will add on to the right with an instance name. Click on the name of the instance and assign a group of metric, metric is the metric group that you just added. See attachment.

• Windows do not install ISO in the NFS datastore

  Hi all

  I searched this forum for a few days and tried to suggestions from different positions without success. I recently installed ESXi 5.1 update 1. I have setup a NFS datastore on the same computer by using a USB external hard drive. I was able to install RHEL6 using an iso from the NFS data store. The problem is that I can't install Windows by using an iso of Windows 7. Whenever the virtual computer is booted, it aims to achieve crashes and boot TFTP. No iso standard is detected. I tried the following:

  1. guaranteed 'Connected' and 'Connect at Power On' options for CD/DVD are verified. However, I have noticed that when the virtual machine starts, the 'Connected' for Windows option becomes not controlled. This is not the case for the Linux VM.

  2. change the boot order in BIOS to the first boot from CD/DVD.

  3. uncontrolled ' connect at power on "for network adapters.

  Even after these changes, VM trying to do a start-up network and TFTP.

  The next thing I did:

  4 network cards removed from the BIOS (by changing configuration).

  For the moment, VM does not network boot attempt, but complains that the operating system was not detected.

  Few details on the NFS datastore:

  1. 1 TB external USB with 2 Configuration of partitions ext4 as an NFS share to the RHEL6 server on the same machine.

  2. NFS configured correctly because I can install from an iso RHEL6 very well.

  Am I missing something? Nothing wrong with iso of Windows. I used it elsewhere. Also tried a different iso Windows without success. Help, please. Thanks in advance for your time.

  Kind regards.

  As the ISO for the operating system files are big and sometimes take a considerable amount of clusters on the hard drive make a control office (or a scan of the drive) can fix corrupt ISO file. and to make sure that your ISO is not corrupted try to open it with Winrar and extract a file from it.

• VMPlayer cannot detect the scanner for all-in-one printer?

  Hello.  I am running Linux Mint 14 in VMPlayer on your desktop AMD Win7 hexagonal base.  The implementation uses a MG5320 Canon all-in-one printer on a wireless network.

  Symptom: When you try to use the scanner under Linux software, I get an error that does not scan.

  Comments: I know that the printer is connected and can print from VMPlayer.  I used the scan software successfully in a Win7 laptop boots double in Linux Mint 14.  Therefore, the only difference is running Linux Mint in VMPlayer.

  How can I get the functionality of the scanner of my all-in-one printer with VMPlayer?

  TNX in advance for all advice.

  The 'virtual' printer in the virtual machine settings through the present printers on the host - there should be no impact on your ability to 'normally' adding printers inside the guest.

  Unfortunately, I'm not familiar with the same type of printer, and I'm not Linux.

  The thing is useful that maybe I can tell you, is that you may need to configure the virtual adapter as connected by a bridge instead of the default NAT.

• slow writes - nfs datastore

  Greetings.

  I note that some write throughput problems I see with a based NFS datastore. Seems I'm not the only one who is seeing this, but so far have given little information in making it better.

  Try the update of ESXi V4 1 on a Poweredge T110 with 4 GB of memory, xeon X 3440 CPU and 1 250 GB sata drive.

  The NFS is based datastore served a machine of OpenSUSE 11.2 on a network of 1000Mb and speed and duplex has been verified to be correctly set on both machines.

  Initially I converted a server image OpenSUSE 11.2 VMware VMware ESXi server (12 GB) in a based NFS data store. It worked, but was incredibly slow, medium flow 2.7 MB/sec.

  Once, I found 3 MB/s writing was everything that I have the NFS datastore using jj. I tried both leave within the virtual machine and also in the ESXi console to the same store location.

  Performance of network using iperf, shows ~940mb/s between the virtual machine and the NFS server so when drives are out of the way, the net is doing well.

  I ended up changing the following advanced settings to see if it is any kind of problem memory buffer;

  NFS.maxvolumes to 32

  NET.tcpheapsize to 32

  NET.tcpheapmax to 128

  Which seem to help, access write from the virtual machine to the NFS data store went from 3 MB/s to 11 MB/s - 13 MB/s. So, there is certainly some slowdowns self-imposed via the default settings are defined.

  Tried to mount the NFS datastore even directory directly as / mnt in the virtual machine hosted and low and write to/mnt watch throughput ~ 25 Mbps. do the same exact command to another linux only box on the same network that I see about the same rate with the stand-alone server see about 2 MB/s more so no problem there.

  I suspect that there may be other elements in which the ESXi NFS based datastore is 50% less efficient than straight NFS. Have other any golden treats to try to obtain the ESXi storage NFS write speed up to something similar to what can be done with native NFS mounted in the virtual machine?

  TIA

  Check the mounting options on underlying partition, for example by the file system,

  -ext3 - rw, async, noatime

  -xfs - rw, noatime, nodiratime, logbufs = 8

  -reiserfs - rw, noatime, data = writeback

  Then export options use (rw, no_root_squash, async, no_subtree_check)

  Check that the IO Scheduler is correctly selected based on underlying hardware (use a rewrite if material noop).

  Increase the NFS threads (if 128) and Windows TCP to 256K.

  Finally ensure comments partitions are 4K aligned (this should not affect sequential performance well).

  I worked on a few notes on NFS, which cover all of this (not complete yet): http://blog.peacon.co.uk/wiki/Creating_an_NFS_Server_on_Debian

• iOS 10 begins to turn background refresh for all applications

  I only update background together 10% of my iPhone apps. This morning is the third time iOS 10A turned on background refresh for all my applications.
