How many vCLS VMs will there be running?Īt most, there will be 3 VMs running.No, the VMs are managed by the ESX Agent Manager, you as an administrator should not need to manage these! Do I need to maintain/update/manage the vCLS VMs?.When new questions or considerations come up, I will add these to the list below. Over the past week(s) I have seen many questions coming in and I wanted to create a blog with answers to these questions. In the 7.0 U1 release a subset of DRS functionality is enabled through vCLS. VCLS is a collection of multiple VMs which, over time, will be the backbone for all clustering services. by decoupling the clustering services (DRS and HA) from vCenter Server via vCLS we ensure the availability of critical services even when vCenter Server is impacted by a failure. You may wonder why VMware introduces this, well as Niels states. Niels Hagoort wrote a lengthy article on this topic here. vCLS provides a mechanism that allows VMware to decouple both vSphere DRS and vSphere HA from vCenter Server.
Datastore usage on disk alarm in vsphere 6.5 update#
But let the vastly superior management option continue.In the vSphere 7.0 Update 1 release VMware introduced a new service called the VMware vSphere Cluster Services (vCLS). Forever (and as far as I'm concerned, leave the web client as an option). The performance ''suggestions' of VMFS 6 over VMS5 are 'enticing', but considering the drawbacks. At this point, I have zero intention of 'upgrading' my production, customer facing environment from 6.0 to 6.5 (at this point, I'd need some insanely ridiculous enhancements in 7.0, INCLUDING the return of the C# client, to go beyond 6.0) - and the performance and reliability of the web client vs the C# client is just.
The Web client is an OK option for day to day simple stuff, but at the and of the day, the C# client is beyond orders of magnitude better than the web client for anything other than the simplest console (and console is debatable with how it interacts with firefox), shutdown or reboot of VMs. And I personally know of others that WILL NOT 'upgrade' to 6.5 due to the termination of the C# client. I simply can't stress how much better, faster and more RELIABLE the C# client was than the web client. And dismally slow in comparison, coming from someone that has been working with VMWare since the 3.5 days. Side 'plea' : Bring back the C# client!!! The web client just plain sucks. So anyone have any ideas how I can delete this datastore, since it sees to think it's in use, despite the fact that I manually deleted everything that was remaining on the DS, and after which there's NOHTING on it, and ALL snapshots that MIGHT be able to cause issues are consolidated into the VMs? So I'm at a point where there is NOTHING on the datastore and there are NO snapshots of any kind even remotely associated with the datastore (even though 'in theory', a storage vMotioned machines snapshots shouldn't care about the previous datastore), but yet the junky web client is not letting me delete the store, and not giving me the slightest clue what it's complaining about. I can put it offline, for both my hosts that access it, and it goes offline/inactive with no warnings or issues - I went so far as to look at all the machines that were originally on the datastore (prior to moving them off it) for machines with snapshots and removed them all - still no bueno. There is literally NOTHING on the datastore. With the web client, however, I have absolutely no idea what it's complaining about. Otherwise, the store goes offline, and from there, delete it and have a nice day. Put the datastore offline, and if for some reason something was missed that would prevent that, it'll tell you before you can ever put it offline. I've removed and deleted datastores many times in the past. Anyway, back on track - I want to remove a VMFS5 datastore and then re-create it as a VMFS6 datastore, since VMFS5 can't be migrated to VMFS6 like previous VMFS versions.
Other than cases where a host that the client was directly connected to rebooted, I can't recall ANY time it had ANY issue). Well, here's my first real major issue with the web client (other than it's slow, clunky, and has various crashes/faults that require a reload orders of magnitude more often than the C# client's NEVER. I'm very much a 'fan' of the C# client, and really hate the 'new' Flash based Web client. To Preface - I've been working with VMWare since around the 3.5 days.
