Software Raid: Installation and Disk Replacement



  • All,

    1. I've a pfSense installation without software raid. Is it possible to re-install pfSense with gmirror and import the old configuration file?

    2. Where can I check the array status and what steps are necessary to replace a disk?

    Can I use gmirror status, gmirror forget before replacing the disk and gmirror insert to rebuild the array?

    Is it possible to shutdown the machine after gmirror forget?

    Thank you in advance!

    1. Yes. Backup the config, reinstall, and restore the config. When reinstalling, use the gmirror option in the installer to make the array.
    2. There is a widget for gmirror status, and Diag > GEOM mirrors for status and disk management. If you have SMTP notifications enabled, it notifies on any status change of the mirror.

    The diag page also offers a way to forget disks, add disks, rebuild arrays, and so on. It doesn't let you create new mirrors, however.
