Hi,
The link on our doc could do with a little more explanation as I've been asked this questions many times now :https://documentation.commvault.com/11.38/expert/resiliency_on_hyperscale_x.html
is the below still correct? :
HSX Cluster with EC 4:2 erasure coding (3 nodes or 6 nodes for example) can tolerate a total of 2 disk failures across the cluster or a single node ...
One would assume a 6 node or more cluster could survive more than 2 disks in total going offline?
Shut down / restarting:
| Erasure Code | Block Size (Nodes / Block) | Resilience Limit | Comments / Description |
| (4 + 2) | 3 Nodes | 1 node per block | Shutdown/reboot only one node at a time. Ensure Commvault services are up on the rebooted node before rebooting the next node in the block. |
| 6 or more Nodes | Up to 2 nodes per block | Can shutdown/reboot up to two nodes at a time. Ensure Commvault services are up on the rebooted nodes before rebooting the next node in the block. |
shutting down 2 nodes on a 6 or more node block - will all new writes be blocked or appended on the other nodes then re-distributed once the other nodes are back online?
