Please answer the below questions :
- When one cvm goes down(in a 10 node cluster with RF3) for 20 mints, then Guest VM’s new write and read IO would be served by anther's CVM and all these will be traveling across 10 g network.
A : Will those new IOs served from local copy via another CVM or IOs will be served from the replica copy
B: Will cluster starts to build a new replica to accommodate the missing copy or RF3
Ques 2 - When new Write IO request comes, first it will write the data on Oplog then synchronously send to other CVM’s Oplog. All host in clusters having 2 SSD and 6 HDDs.
Will Write IO process by both SSD in every host or only one SSD is hsving Oplog partition active at the same time ?
I think there is only one oplog per CVM/host whether the host is aving all flash drive or 2 SSD and remaining HDD. But I am not sure about this statement, Please clarify..
