Here are the steps in order to properly smartfail out a node pool that is no longer needed in the cluster
1 – Move off the majority of the data through File Pool Policies
Once the File Pool Policies have been changed, start a Smartpools job in order to apply the changes that were made. If the File Pool Policies were configured correctly, this should move the majority of the data.
Note: It is normal for there to still be some space utilized on the Node Pool (generally under 5%, but it can be more). This is fine and won’t cause any issues.
2 – Ensure Global Spillover is enabled so the last bit of data on the nodes are allowed to move to other node pools
# isi storagepool settings view
File System -> Storage Pools -> SmartPool Settings
If it isn’t enabled, ensure that you get it enabled
# isi devices -a smartfail -d <node LNN>
# isi devices node smartfail –node-lnn=<node LNN>
When the Smartfail process completes (which is handled by a Flexprotect Job), move onto the next node.
Smartfail them 1 at a time until you have 2 nodes remaining. Once you are at this point, start the Smartfail process on both nodes. To have Node Pool quorum, you need at least 51% of the devices online. If you Smartfail just 1 node, then the Node Pool no longer has quorum and will be unable to complete the Smartfail process. By putting both nodes in a Smartfail status, the data will be striped to the other node pools.
