VMware NFS Datastore lost from config during Snapshot

[vMarkus_K]

Hi,

I`m using SC 3.6.

I have 2 VMware DS Configured (iSCSI and NFS), during the Snapshot process the NFS store is removed from Konfig.

is it maybe a problem with the export:

[Arora_Kapil]

Hi,

This might be a dumb question, but I have to ask.

Do you have any VMs inside hekate_vmstore00_nfs datastore?

Kapil

[vMarkus_K]

HI,

yes all VMs are running in this DS.

Update 1:

if I change export to this (remove qtree and use original path as export path):

root-lab-fas2050> exportfs

/vol/vol_vmware_03      -sec=sys,rw=172.16.50.201,root=172.16.50.201

then everything works fine.

and also when i use a qtree everything is fine:

root-lab-fas2050>

root-lab-fas2050> exportfs

/vol/vol_vmware_03/qtree_vmware_03      -sec=sys,rw=172.16.50.201,root=172.16.50.201

semms to be a problem with -actual option

root-lab-fas2050> exportfs

/vmware_03      -actual=/vol/vol_vmware_03/vmware_03,sec=sys,rw=172.16.50.201,root=172.16.50.201

[ktenzer]

I think this is a bug on our end, we do not expect the "-actual" so I would export without this option if you want to use SC.

SC has to figure out from the storage system what volumes are involved since we cant do it from ESX. For NFS this involves looking at exports.

Kapil can you bring this up to Matt and have engineering look at this and open a bug?

Regards,

Keith

[ktenzer]

Oh another option is, forgot

You can turn off SC discovery in vmware plugin...VIBE_DISCOVERY_something is the option. If you set this to N then the config file will never be updated and it should work with -actual. Only problem is then we arent detecting if you move a VM to a new datastore so you would have to update config manually and add new datastores / storage systems when they are added.

Regards,

Keith

[vMarkus_K]

OK,

Disabling SC discovery is an option. I will try it.

I think there is only a manual add of new Volumes and Datastore / Share in the config necessary, is that right?

Moving VMs between know resources shouldn’t be a problem?

But the best way is to fix this issue, a lot of people use this export-way...

[rmatt]

If you want to set all the volumes into "manual" state, set:

VIBE_DYNAMIC_VOLUMES_UPDATE=N

This will prevent the update of VOLUMES, SNAPMIRROR_VOLUMES, SNAPVAULT_VOLUMES and NTAP_DFM_DATA_SET.  If you want to set those values manually at that point, you can.  This will help you if you still intend to use RDMs as the vSphere/vCloud plug-in doesn't support RDMs directly.  The risk element is that if you move the VM from one Datastore (backed by a volume) to another and that isn't in your VOLUMES parameter, it will be quiesced/unquiesced but not be backed up from a NetApp snapshot standpoint.

Thanks,
