• Stretched cluster VSAN with SRM

  Hi Coomunite,

  Stretched cluster VSAN can use replication on Bay?

  Is it for the use of VSANS with MRS?

  Good afternoon, a stretched cluster vSAN is not replication table that can be used with MRS.  He's tense storage which is synchronous and for use in areas without installation at disparate locations.  Thank you, Zach.

• Disk groups are not visible cluster. vSAN datastore exists. 2 guests (on 8) cluster do not see the vSAN data store. Their storage is not recognized.

  Do not know how even tear it down and rebuild it if the disk groups are not visible. The discs are in good health on each host storage adapters.

  Currently the latest version of vCenter 5.5. Hosts running 5.5 build 2068190

  Just built. Happy to demolish and rebuild. Just do not know why it is not visible on the two hosts and the disk groups are only recognized 3 guests when more are contributing. Also strange that I can't get the disk groups to fill in vCenter. I tried two different browsers (chrome and IE).

  I have now works.

  All the identical 5.5 relies on ESXi hosts. All hosts are homogeneous CPU/sum of the prospects for disk controller / installed RAM/storage.

  I have work. I had to manually destroy all traces of the vSAN on each single to help host node:

  (1) put the hosts in maintenance mode and remove the cluster. I was unable to disable vSAN in the cluster, I made on each node host (manually via the CLI below) then disconnected web client vCenter and return to finally refresh the ability to disable on the cluster.

  esxcli vsan cluster get - to check the status of each host.

  esxcli vsan cluster drop - the vSAN cluster host.

  storage of vsan esxcli list - view records in the individual host group

  esxcli vsan storage remove-d naa.id_of_magnetic_disks_here - to remove each of the disks in the disk group (you can ignore this using the following command to remove the SSD only falling each disc in this host group).

  esxcli vsan storage remove s naa.id_of_solid_state_disks_here - this is the SSD and all the magnetic disks in a given disk group.

  After that, I was able to manually add hosts to the cluster, leave maintenance mode and configure the disk groups. Aggregated data of the vSAN data store is correct now, and everything is functional.

  Another question for those of you who still read... How to configure such as the VM storage strategy that migrates towards (or inspired) the vSAN data store will immediately resume the default storage policy, I built for VSANs?

  Thanks for anyone who has followed.

• 6 host Cluster VSAN - I want to change the IP vmkernel VSAN

  Hello

  as the title says, I have 6 cluster host VSANS 6.2 (with some VMS on the store of data VSAN, off right now). What is the best method to change the addresses IP of VSAN vmkernel, without loss of data...

  Someone did he do such a thing? The last byte will change slightly to the decline in the number... None VLAN / subnet etc. changes... I have just change the VSAN vmkernel and change the last octet...

  See you soon

  Paul.

  I re-IPed hosts and their IP of vmk corresponding VSAN in maintenance mode as you describe. With all that in maintenance mode, you can just go and change it. I don't think that there is no danger of data loss. If you make a mistake and all start, it would detect split partitions network or other network through the assessment of health problems and you would have a data store does not work until you fix the network problems.

• All vsan configuration utility for flashing in vsan 6.2

  shouldn't we mark drive flash as a flash capacity either from command line or any flashing utility in vsan 6.2? Is this intelligence now incorporated into the web client itself, when we select the option level capacity while creating the disk group?

  You may notice in the user interface with 6.2 which drive is a capacity, which is put in cache and even mark them as local. not required for the script more

• Error "host cannot communicate with all other nodes in the cluster of enabeld VSAN.

  Hello community,

  We have a problem (?).

  We have a cluster VSAN enabled with four hosts. Everything seems perfect,

  -the configuration is good,

  -Displays the page state VSAN "network status: (green arrow) Normal."

  -Displays the disk management page "status: healthy" for all of our groups of disks.

  -Same 'esxcli vsan cluster get"on each host returns a 'HEALTHY '.

  But we have a yellow exclamation littly on each host 'host cannot communicate with all other nodes in the cluster of enabeld VSAN.

  Anyone with the same problem? Anyone with an idea or a hint?

  Thank you!

  Update vcenter to the latest version and the error disappears. Problem solved! The 'old' version of vcenter performed since September 2014, strange.

• Update VSAN task configuration failed for ALL 3 ESXI hosts

  I enabled VSANS on the cluster, but the task of updating VSAN configuration failed with the below error

  Operation failed, the diagnostic report: not associate the host to the cluster VSAN (Exec command "/etc/init.d/vsanvpd restart" succeeded, but came back with zero State: 1).

  On all esxi hosts 3, I can see a warning

  Host is in an active VSAN cluster but doesn't have a Service of active VSAN

  Please help me fix this isseu... I need all the VSAN here experts... I do not find a troubleshooting for this issue.

  This information was supposed to do in the VSAN Release Notes, although I must admit that I don't check that they exist.

• Will be older, slower, diskless / nodes consumption slow down a VSAN system?

  Hello

  We have a 6 identical VSAN contributing storage of cluster nodes.
  We have also two old machines (think generation Proliant G7), which are simply 'broad' and we thought to use these two to host performance reduced, not part of the virtual computer, which we have many offshore.

  Question: these two boxes older, which are much slower than today's material, will drag down the performance of the entire solution VSAN. 6 nodes, contributors 'feel' the presence of these aging and all devices slow down?

  There are best practices do not use a cluster asymmetric but does that refer to contribute nodes only?  I understand that the nodes 'consumers only', basically just "sitting there" but when will be the part of the Cluster vSAN, they have a negative impact? If so, why?

  The network connections will be 10 gig and identical to the 6 contributing nodes. It's just the performance of the processor that are slower.

  We will use the affinity / no affinity rules to keep those "low performance" VM on these older machines.

  Kind regards

  Steven

  Hello, this is my understanding of your configuration.  6 new nodes in a cluster of vSAN contributing storage.  2 old nodes in a cluster of vSAN contribute not storage.  I would not expect the old 2 knots to affect performance.  Just my opinion, no way for me to provide proof.  Thank you, Zach.

• VSAN investigations SRM

  1 SRM cannot be installed on a WIndows-based vCenter? or it can work between Windows-based and device base vCenter?

  2 in which case we will use VSANS, I can only do vSphere replication to replicate production on the recovering site? Can anyone suggest where I can place my datastore placeholder? Then I like a disc on my local server, or it must be on a SAN attached storage? If it is possible on a local storage, can I use a single placeholder datastore resident on a host for the entire cluster VSAN, or I will need to have data store separate placeholder for each host in the cluster VSAN?

  Yes, you can have vSAN accommodation your VMs on the vSAN and protected site used as the data store target for vSphere replication to the site of DR. You can also use the data store vSAN on DR site as a placeholder data store, however in this case, as Mr. Khalsa remarked "you want to make sure that your replicas are placed in folders and your placeholders in a different folder."

  You can also use another store of data shared on the site of DR spaces reserved, assuming you have a. This could facilitate the configuration and management, but that could be associated with an additional cost.

  Placeholder updated VMs on the data store local / non-shared, if my memory serves me right, would result in VMs started only on host (s) who can see the placeholders when you press the red button. Normally it is therefore proposed to put placeholder VMs on the data store shared.

  I hope this helps.

• vSAN upgrade from 5.5 to 6.0 - Timeout to complete the operation

  Hi all

  I've been running a 5.5 vSAN configuration identical to William Lam to the virtual Ghetto (a killer custom installation of Apple Mac Mini running VSAN | virtuallyGhetto) for some time and the only reason not to upgrade more far was because of wanting to maintain a configuration of 5.x Horizon view inherited who needs vCenter 5.5. I've now decided this should not dictate my whole environment then after a successful move to 6.0 on the hosts and VCSA, I thought I would upgrade to vSAN 6 to take advantage of the improvements it brings, not to mention to remove the nagging alerts on the vSAN update available.

  After running through the prerequisites this fact compensation involved in a number of vswp files inaccessible, vSAN reported a good state of health and so I started with the upgrade online, be sure to include - allow-reduced -redundancy I have a 3-node cluster.

  When running and after about 20 minutes of nail biting (by accepting the fact that his machines of laboratory accommodation only, their fate can be determined by the success of failure of the upgrade), I received the following in the TVR: -.

  : Deletion of this VSAN disk group failed

  : A general error occurred: could not evacuate data for disk uuid 52da00fa-c8f2-fdb8-924c-3007d480ac4d with error: timeout to complete the operation

  : Cannot delete the VSAN disk, leaving group.

  : Upgrade tool stopped due to the error, please address reported the problem and run the tool again to complete the upgrade

  Someone at - it guidance on how to approach the time-out, or he could escape that I would understand rather the root cause that blindly blow to remove all of the configuration and reboot.

  Thanks for your help!

  All the best

  Hi Duncan,.

  I managed to work around the problem in the end, in a weird way. I ended up changing the default vSAN FTT from 0 to 1 storage policy and reapplied to redistribute the data or the light evenly on the hosts as expected to the compliance of the report. After a few hours, I then changed the default vSAN strategy towards an FTT of 0 and again applied. By running the TVR command with the parameter - allow_reduced_redundancy again by the failed sequel, but a quick check on the vSAN has shown that the majority of data consumption was now on the hosts 2 and 3 with a tiny 3 GB of use reported against the disk of the host of the first group. At that time, I've been manually the disk group on host 1 (choose not to evacuate the small amount of data that has been left). After you re-create the disk on the host group, it automatically came back in as v2 and I repeated the process described above in the other two hosts effectively the content of vSAN brewing between the hosts and drop what I believe has been corrupted/no valid data on the host group could not be evacuated by the upgrade process.

  At the end of it, all my virtual machines survived the upgrade of vSAN.

  See you soon

• Rebuild the node VSAN procedure

  Hi all

  We bought a cluster to VSAN 3 knots of Dell. The material was ordered without SD card in mirror. So the hypervisor is running on an installation that is not mirrored.

  I have ordered from 3 additional SD cards and will reflect.

  What I do is take members on only one node at a time and reflect SD cards, and then restore the configuration of ESXi.

  What I've done so far is to back up the config ESXi powercli with the following command.

  Get-VMHostFirmware - $vmhost ESXi_host_IP_address - BackupConfiguration - DestinationPath output_directory

  
  

  So, my need is now to take down my first node and proceed with mirroring. Can someone give me the correct procedure to restore a VSAN node? Is it as simple as that...

  
  

  
  

  • Reinstall the same version of ESXi.
  • Run Set-VMHost - VMHost - ESXi_host_IP_address 'Maintenance' of State
  • Game-VMHostFirmware - VMHost ESXi_host_IP_address-restoration - SourcePath backup_file - HostUser HostPassword username - password

  
  

  Will this make me return to the State that I was before?

  
  

  Before taking to the bottom of the host, is it possible to move all the components for the other 2 members VSAN first?

  
  

  Thanks in advance.
  

  As Zach mentioned, your mirror to SD cards should not involve the need to rebuild a node VSAN. Maintenance mode ensure accessibility (OK for the maintenance of less than 1 hour) or full Migration would probably be enough for what you do. Depending on how much data you have and how fast your disks are full Migration may take a long time but is the safest option.

  However if you need to rebuild a node due to the failure hardware host for example, you remove the disk for the failed VSAN host group and then remove the failed cluster host. Then set up a new host of work, reinstall ESXi, configure network/vmkernels etc., add back to the cluster VSAN and lasly re - add the disk to the new host group. I have also rebuilt hosts on my pile of RAID0 and HBA for example with this procedure, and it works fine.

• vSan with just 2 hosts?

  Hi all

  I am currently on a trajectory of vcp - VTC 6 and covered only briefly in the vSAN.

  I'm really looking forward to try this at home, but the problem is that I have only two servers (HP Gen8 MicroServer)

  I have seen that it is possible to nest hosts esxi etc but is it possible to use two medical examinations?

  Thank you!

  mattg1,

  You can work with just two hosts or even a single, if you change the default storage policy to include force_provision set to true, depending on what stage you are at the. You will have a second replica on his own diskgroup, but if it's just for a laboratory at home for educational purposes which will be very well. VMware refers to this a strapping 'start-up' and you will see that it is actually supported during the construction of a new cluster (greenfield) where vCenter has not yet been yet (emerging) installation. In other words, you can build a host in a cluster VSAN just so that you can configure vCenter Server and then add the rest of the guests (if any) as soon as vCenter is up and running.

  «By boot strapping Virtual SAN without vCenter can fill this gap and remove the obligation to have storage high availability or temporarily on the local drive to day - zero operations.» This could be applicable to a greenfield deployment scenario. »
