RF2 case with 3 node cluster and 3 disk failure in same node

Hi AnishWalia,

Thanks for your information and help.

So, if 2 x failed disks in same node (Under RF2 situation), may i know whether the node will be down or not? or still operate? Thanks

hey @KC93 it’s a pleasure to help.

So it depends on whether SSDs are failing or HDDs are failing.

Say 2 SSDs on the Node go bad at the same time, then definitely the node will be down, but not in case of HDD, say 2 HDDs fail on a Node, it can still function but with less space and less chance of Node failure.

Hi AnishWalia,

Thanks for your information. Very Clear….

That’s mean if 2 x SSD down, CVM will down. May i know the default CVM location should be under SSD slot 0 right? If SSD drive in slot 0 failure, CVM will be rebooted into SSD slot 1 right?

And if another situation is if only CVM down, the underlying storage will become inaccessible and thus those VMs need to go to another node to get data via 10GE network, right?

Thanks again

Yes @KC93 , that is correct. 

Say if for some reason a CVM is down and its storage is inaccessible, in that scenario the VM’s storage/data IOs will be taken care of by other CVMs or other nodes in the cluster.

You can get more information about this here https://nutanixbible.com/ . Just search for Node failure.

I hope these help.
