You mean “spinning disk” metaphorically, right? Or is there any reason to not have it in low power standby mode? I don’t have any hot spare in my server, but on my desktop I use hdparm to spin down a rarely used storage drive just because it’s so loud.
Comment on How bad of an idea is it to use computing HDDs in a DIY NAS?
eleitl@lemmy.zip 1 week agoI can explain in more detail later.
A hot spare is a spinning disk that is known to the system and is automatically added to a RAID/pool when a disk there fails, and then triggers rebuild/resilvering if the RAID.
A cold spare is a disk added manually by the user.

Yes, just powered so the system is aware of it.

So if you can use a hot spare is mainly depentend on the OS you use I suppose?

Hardware RAID host adapters can handle hot spares OS-agnostically, but for zfs these days it means Linux or *BSD. For a NAS I would go with a BSD distro, for hyperconverged Proxmox on top of Debian.
