Informations about gmirror / geom-mirror integration?
-
I am interested in installing pfSense on a software RAID 1. However the only information I could find about this is that the installer supports it (http://doc.pfsense.org/index.php/Create_a_Software_RAID1_%28gmirror%29). I couldn't find any information about the integration of the raid support into pfSense:
- How about monitoring RAID status from the webinterface? how about email notifications?
- How about replacing a failed disk - just plug in the new disk or do I have to run some commands (according to http://www.freebsd.org/doc/handbook/geom-mirror.html I have to run some commands, but maybe it's better integrated in pfsense?).
- Any disadvantages over a real RAID controller? (except for performance, which I don't care about as there isn't relevant disk access from within pfsense)
etc.
Thanks for any hint!

We had most of that info on the doc wiki, not sure why it was removed.
I added it back. http://doc.pfsense.org/index.php/Create_a_Software_RAID1_%28gmirror%29

thank you jimp,
somehow I didn't get a mail notification, so I saw your reply just now. Are there plans for extending the RAID support, e.g. mail notification, spare disks and just needing to insert a new drive that gets automatically used/added as spare? I don't know if that's possible, but as RAID 1 mirrors everything, shouldn't it be also possible to mirror to some kind of loopback device, so one can create a complete image of the pfsense installation while it's running for backup purposes? :-)

not sure what the plans are there.
Eventually we'll have a more full-featured notifications system but that won't be ready any time soon. When that happens, notifying of a mirror failure would be possible.
Not sure about mirroring to a loopback device or anything like that, that's all up to gmirror. We can't really automate a lot there safely.
