Mirrored Boot Drives

[rfielder]

It seems that setting up mirrored boot drive is eeasy witg FreeNAS.

Are there any advavtages beyond fail-over if one drives dies?

If one boot drive does die how do you replace it? Is that a full shutdown and drive swap?

Will FreeNAS then rebuild the new boot drive? Or must you do an install of FreeNAS to the new drive?

Hello,

SSDs are more reliable than USB sticks (and HDDs) but sometimes can fail. I don't think that are other benefits other than redundancy fo mirror them. Boot devices must be used just for booting.
You can bring the drive in the offline state and replace it from the GUI. You can find the steps in the manual.

From what i know, the config file is backuped automatically. So if you have a single boot drive that it's failling, you can still recover the db that can be imported after the fresh FREENAS installation on a new device.

Perhaps I am misunderstanding something. Where is that config file backed up to? Are you referring to the mirrored drives in a mirrored boot pool both having a full copy of all configs?

The .system dataset, which is put on your data pool by default once you create one. You'll find it at /var/db/system/configs-longhexnumber on your system.
