vCenter Disk components marked as absent - Parent disks are present.

I have a nested environment, which was cleanly shutdown in preparation for maintenance of the physical servers where they are hosted.

There were some communications issues at first, but I was eventually able to get all six nodes in the cluster to rejoin. All VMs in the nested environment came back healthy, except the vCenter server. I was able to use the parent vCenter's instance of RVC to connect to each of the hosts in the nested cluster. I then ran a vsan.vm_object_info for the vCenter VM.

Object info for vCenter VM from RVC

vsan.vm_object_info /10.25.0.21/ha-datacenter/vms/hzn-vc.mars.lab.adms.local/

In order to determine why the host locations are unknown I generated a report of the UUIDs of the disks in each ESXi VM:

Procedure to generate and audit disk UUIDs when cmmd-tool failed to find the UUIDs reported.

#following command was run on each host, and the output aggregated.

esxcli vsan storage list | awk '/^naa/{gsub(/\n$/,""); printf("%s ",$0)};/VSAN UUID/{print}'  | sed -r "s/^/$(hostname)\t/g"

As you can see, the devices are present with the appropriate UUIDs, but the cmmds database is unaware of the relationship (hope I am using the proper terminology).

Any one have any ideas as to how I can get the VMs disks objects to be marked as ACTIVE and aware of its policy?

Hello marsherian​,

I would start by checking the state of hosts hzn-03 and hzn-04 and their disks:

Check (from any host) that they are not in a Decom state (e.g. decomState: 6) as per CMMDS:

# cmmds-tool find -t NODE_DECOM_STATE -f json

Check that all of their disk-groups are in CMMDS and functioning normally:

# esxcli vsan storage list

RVC usually will indicate this also:

> vsan.disks_stats <pathToCluster>

I have noted in nested labs that disk-groups not being mounted on boot due to insufficient memory heap can occur, you should see this in the boot.gz/vmkernel.log.

Are there any healthy active components on those same disks?

TheBobkin​ thanks for the pointers,

The disks aren't in DECOM, but there are no other objects are present in the two nested hosts:

Hello marsherian

"The disks aren't in DECOM,"

Well actually this is the node decom states but yes the disks are not available for component placement if the host is in decomState 6.

As an aside, CMMDS is per cluster, not per node thus why you have the same output from running this on hzn-03 and hzn-04 with both showing entries for all nodes in the cluster.

"One item that may be of interest, there are no stats for the vmdks for the broken VM"

This is expected - if the Object is inaccessible then you can't see its stats.

"It looks like the data just isn't there anymore."

As I said in my last comment, there are only really 3 feasible reasons why all components on a particular host would be inaccessible:

1. Node is in a decom state (not the case here but to be sure for sure you can refresh this using #esxcli vsan maintenancemode cancel).

2. Host is network partitioned from the other cluster members (easily verified by checking the membership count using # esxcli vsan cluster get).

3. Disk-group(s) unhealthy, not in CMMDS, not mounted at boot - I reckon this is the most likely cause here and is easily checked using a variety of methods (e.g. Proactive VM creation test, attempting to create Objects that require 5/6 Fault Domains (e.g. a R1, FTT=2 Object or a R5/6 FTT=2 Object), checking using #vdq #esxcli vsan storage list, observing 0 IOs via #esxtop (U or X)).

Thanks for clarifying.... understanding who, what, when, and how the objects are stored is a dark art when one is peeling back the layers of the onion... very easy to get the wrong end of the stick.

Cluster network partitioning was the initial cause of the problem, all hosts-vms are present and connectable now.

Alas, the VM creation tests, etc are not possible since the missing VM is the vCenter VM.

I've been running all of the commands per-host to see if there is some discrepancy in their opinion of the state.

Oddly, vsan.cmmds_find from rvc (connected to each host individually) Shows the DOM_OBJECTS as healthy for each of the disks. It's a rather lengthy file so I've attached it below. The owner denoted for most objects is hzn-02 and hzn-05 for the remainder:

$ awk '/Healthy/{print $8}' ~/hzn-vc-cmmds_find-perHost.txt  | sort | uniq -c  | sort -nr

Hello marsherian​,

The only Storage Policy appearing here is 'Default Virtual SAN Storage Policy' that has been modified to be FTT=0 and Stripe-Width=6 - what this means is that each DOM-OBJECT is striped over 6 LSOM-OBJECTs (AKA components), inability to access even one of these components will result in the DOM-OBJECT being inaccessible.

Of the output you posted, there are currently 30 state:5 (ACTIVE) components and 330 state:6 (ABSENT) components.

For every DOM-OBJECT there is a CONFIG_STATUS entry that informs of the current availability of the DOM-OBJECT, in your case this is not just the vCenter/PSC vmdk Objects but numerous others that are inaccessible. The term 'Healthy' here is actually a reference to the state of the CONFIG_STATUS itself, not of the Objects it describes.

In the output you posted there are only 4 Objects which are state: 7 and thus healthy, the rest are 12 and 14s which mean the Objects are inaccessible and non-recoverable in their current state:

"Cluster network partitioning was the initial cause of the problem, all hosts-vms are present and connectable now."

How are you determining that they are now clustered?

Do all hosts state that cluster membership = 6 when checked using # esxcli vsan cluster get?

Is the cluster revision count incrementing? (indicating membership flapping)

Is this a vSAN 6.6 cluster and using Unicast or Multicast?

Is traffic being passed both ways via the vSAN-enabled vmk on each node?

[Host1]# vmkping -I vmkX <IP of vSAN-VMK on Host2>

I note that there are only 3 nodes in this case that have state:5 components (and as a result seemingly accessible Objects):

"faultDomainId"=>"594d4721-e1d2-a466-5f38-005056b34157",

"faultDomainId"=>"594d488f-4f6b-48e2-9fee-005056b30d27

"faultDomainId"=>"594d4782-6f02-c98b-6e2a-005056b3fb13

This would indicate these hosts can communicate with one another but not the others.

"Alas, the VM creation tests, etc are not possible since the missing VM is the vCenter VM"

Sorry there, lost track of your initial point that vC was down - posting RVC output made my head assume it was up (yes, using another vC)

First of all, thank you very much... you've educated me greatly on the internals of vSAN and cleared a lot up!

My policy choices in this environment were made with performance, and not resiliency in mind when we were short on space in the parent vSAN... when we expanded, I never adjusted!

I really appreciate you explanation of the CSN states, and that the report status of "Healthy" is a bit misleading. Might you be able to point me at docs on the state definitions?

How are you determining that they are now clustered?

->via esxcli vsan cluster get.

Do all hosts state that cluster membership = 6 when checked using # esxcli vsan cluster get?

-> They do indeed.

Is the cluster revision count incrementing? (indicating membership flapping)

-> It was whilst I was debugging the comms between hosts. (The maintenance we'd done was re-wiring the network, and I failed to properly set the MTU on the NSX network where these nested environments sit, which lead to the flappy connectivity in the nested environment.)

Is this a vSAN 6.6 cluster and using Unicast or Multicast?

6.6.1 in Unicast.

Is traffic being passed both ways via the vSAN-enabled vmk on each node?

I have validated full daisy-chains of ping. #[hostn] vmking -I xmkX [vsan-vmknic-host(n+{1,6})]

I think my poor striping and FTT choices months ago have bitten me, obviously. Why the data should have gone AWOL on the VMDK of the ESXi hosts in the cluster is a bit concerning though.

I'd never have that FTT/striping in a real environment, but understanding how this broke will assist in advising customers on proper policies in real life.

Again, thank you so much for your participation in this, it's been invaluable.

Hello marsherian​,

"First of all, thank you very much... you've educated me greatly on the internals of vSAN and cleared a lot up!"

Cheers - this is fairly similar stuff to my day-job (GSS) but I care enough about this product to help out in my own time where possible.

"I really appreciate you explanation of the CSN states, and that the report status of "Healthy" is a bit misleading. Might you be able to point me at docs on the state definitions?"

I don't believe there are any (official) external documentation relating to these nor CMMDS-Tool in general, likely due to the potential for misuse that could result in people breaking their data.

The basic rule of thumb for DOM-Object availability/recoverability is: even number=bad, odd-number=good (13 being a gray-area here as this means ACTIVE data component but no quorum, so creating a working  Object from this requires some minor hackery).

While cluster membership showing all members indicates these *are* clustered, can you double-check the Unicast agent list on all hosts and ensure all of them have all other hosts entries correct? (and marked as Unicast=1)

"I think my poor striping and FTT choices months ago have bitten me, obviously. Why the data should have gone AWOL on the VMDK of the ESXi hosts in the cluster is a bit concerning though."

vSAN can get a bit 'quirky' when you nest it, thus why this is unsupported. I have seen some odd things in nested labs but never had any issues with Data availability despite my best efforts to break it.

What are the 'disks' of these nested hosts backed by? VMDK Objects on another vSAN? If so - are these Objects healthy?

I will PM you a few last-ditch efforts that might help here.

Bob
