On my primary SCALE server, I have one pool that's a 3x10TB HDD mirror with datasets and another pool that's a 2x4TB SDD pool for VM ZVOLs.
Separately on my network, I have OPNSense installed on bare metal as my firewall/router. I am planning to move OPNsense to a VM on SCALE, which will allow me to get rid of a piece of hardware and reduce energy usage.
However, once I move OPNSense to a VM on SCALE, it will become nearly impossible for me to ever shut down the SCALE server if I need to do so, especially if it happens during the business day since my spouse works from home and needs to be online in order to work, and if OPNSense is virtualized on SCALE, taking down the SCALE server will take down the entire network in my house.
Therefore, I am investigating the idea of adding hot spares to both pools or at least an extra HDD and an extra SDD so that if a drive in either pool ever fails, I can take it offline, add a new drive, and resilver without ever shutting down the SCALE server.
It looks to me like the process of adding hot spares to an existing pool involves adding a VDEV and selecting the spare option. Is this what people recommend? Or is there even an advantage to adding hot spares? It seems to me that I could just install the extra HDD and extra SDD, and if I ever need them due to a drive failure, I could add them to the pool then.
