Rename the NFS datastore?

• 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.

• How the NFS Datastore

  Hello

  I know I'm asking a question of dump here but just want to know were looking for we can measure NFS volume in vShpere 5.0 or not?

  -Amit

  You just need to extend the NFS volume in your level of storage, just at the vSpehre rescan, if failed, necessary to go back to the nfs. (Depends on your type of storage)

• Reconnect the NFS Datastore

  Hi all

  When an NFS server reboots the data store in my ESX 4.1 shows inactive. Is anyway to reconnect to the NFS data store without having to restart the ESX host?

  TYIA,

  Hello.

  Eric Sloof has some information on his site about it that might be useful.

  Good luck!

• 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.

• Is it possible create Oracle RAC on NFS datastore?

  Hello

  Is it possible create Oracle RAC on NFS datastore?   With the VMFS data store, we use VMDK files as the Oracle RAC shared virtual disks with the Comptrollership and multi-writer SCSI Paravirtual, what about the NFS datastore? is the controller SCSI Paravirtual and writer multi function supported on the NFS datastore?

  Unless I'm missing something, this is not supported on NFS.

• Cannot add the NFS share to store Cluster data

  Hello

  I have this scenario:

  Server - FREENAS with NFS share

  -cluster with 2 guests

  I added the NFS datastore successfully to each host in the cluster. The problem is when I try to add the NFS Datastore for the Cluster data store, I get the error: a specified poarameter was not correct. datastore.info.type.

  Any suggestions would be much appreciated.

  Thank you.

  Datastore1 and datastore2 data warehouses are data warehouses local? If so, you must remove these storages of data added before the NFS datatore to the cluster, first cause a cluster cannot be VMFS and NFS on the same cluster and second cause without making sense have warehouses of local data within a cluster data store.

• Cannot remove/remove NFS datastore because its use, but is not

  I am trying to remove an old NFS data store, but I get an error message saying that it is in use. I find the virtual machine that he believes is used, stepped through all the parameters of the virtual machine and there is nothing pointing to this NFS datastore. I also tried to remove the store of data from the command line using 'esxcfg-nas - d < NFS_Datastore_Name >. That returned an error saying "unknown, cannot delete file system. Even 30 minutes before I was access and moving data out of this data to another ESX host store. I don't know what else to try. Can someone please help?

  It also still shows up on top of the virtual machine as used storage an idle...

  The virtual machine has an active overview that was created while the virtual machine was on the NFS datastore?

• Curiosities: what happens if I restart the NFS server?

  Hi guys,.

  I use Linux as a NFS data store. I'm just curious, regularly there as updates of the kernel, etc. that requires a reboot. What happens if I restart the NFS server without:

  1. turn off the virtual machine on it

  2. without disconnecting the ESXi host data store

  What is the proper way to restart the NFS server?

  Thanks ^^

  If you mean 'a good' (without no timeout error appears in the log), then delete NFS datastore is the whole procedure before you restart the NFS server. Unlike datastore VMFS, by removing the NFS datastore, that this will not completely remove the storage at all, instead you only remove it from the ESX host and you can reconnect the NFS mounting even whenever you want.

• 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).

• Cannot add the new nfs datastore

  Hello

  I would like to get some advice how to add a new nfs data store. Here are the steps I did:

  (1) I have setup a stand-alone ESXi 4 server. I configured the VMNIC0 with 192.168.100.1/24 IP with Vswitch0.

  (2) I have setup a NFS storage. The NFS share is file://\\192.168.200.2\share. I tried using a Windows laptop and I can access the share.

  (3) ON the ESXi server, I created another Vswitch1 with VMNIC1 IP 192.168.200.1/24. I connect my storage to VMNIC1. ESXi, I'm able to ping my storage 192.168.200.2.

  (4) I connect my Windows laptop (IP 192.168.100.2) to VMNIC0. I am able to Vsphere Client to the ESXi server.

  (5) using the Vsphere Client user interface, I click on 'add the new data store '. The fields that I get are "192.168.200.2" and "share". I got the below error message:

  "Error while configuring the host: NFS error: unable to mount filesystem: unable to connect to the NFS server.

  What it went wrong?

  Kind regards

  Kent

  No claim, the NFS must be in the same subnet as your ESX VMKernel Port and your VI Client must be in the same subnet as the Console of the ESX Service / Management Port. But in many cases (especially with ESXi and if not configured otherwise) management and VMKernel are on the same Interface / subnet.

• What is the size of the max file on an NFS datastore

  the blocksize parameter sets the size of the max file on a LUN data store, but I can't seem to remember or find information about the maximum file size permitted with a NFS data store.

  any information or references would be appreciated.

  personally, I wonder if that format of underlying disk as ntfs or ext3 for zfs as determined by the o/s

  Thank you

  Wayne

  As much as I know there is no size limit of the NFS file - it depends on your OS - all that it supports (if you plan to use this file inside the virtual machine) and the size of your NFS share.

  As a general rule people tend to apply limits of san to NFS, just to put a figure on it.

  PS I did some tests with 2 TB filesize on NFS.

• NFS datastore = &gt; no host not connected, impossible to remove

  Hello

  I have a NFS datastore (it was an ISO repository), I need to delete.   So I deleted all records from this share

  My problem is I disassembled it all hosts and the data store is still visible in my inventory and I am unable to remove it.

  When I try "Datastore Mounte to... additional host", the Wizard run in an endless loop and does not load the list of hosts.

  On my hosts, the NFS share is not visible. So nothing stuck because of a file in use.

  Have you already encountered this problem?

  Sorry found the culpit... instant on the virtual machines (with mapped CD-ROM).

• VM shows this in the NFS data store after passed to the vmfs data store

  Hello

  (1) create a virtual machine using NFS datastore

  (2) had created a few snapshots

  (3) to migrate this virtual machine from the data to the local VMfs store

  (4) all the files are moved to the defined vmfs datastore

  (5) storage > > nfs_datastore > > objects > > VM > > vm is present

  (6) but when did change the setting of this VM, vm is present on the data store local vmfs

  The .vmsn file contains binary data text, so you better not change it manually. The purpose of these files is to be able to return to his instant partner. Depending on the configuration of virtual machines in time you created the snapshot, the virtual machine may require access to the old data store to access the files and folders in there when you return to this snapshot.

• 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.

  use triggers esx.problem.storage.apd. *.

  When NFS disconnects you will get official messages in the file vmkernel.log on the host
