[9fans] fs(3), venti, raid, and more

["Devon H. O'Dell" <devon.odell@gmail.com>]

Hey.

I'm setting up a fileserver. Right now I have 2 250GB disks in it,
that I would like to mirror. I don't particularly care to mirror
single partitions. I want the whole damn thing to be mirrored, and
when anything happens to it, on any partition, it should be synced
between the two.

I'm lead to believe that this is possible by using fs(3). I've put:

mirror rootmirror /dev/sdC0/data /dev/sdD0/data

into /dev/fs/ctl, and put this into a partition accessible through
/dev/sdC0/fscfg

#1) Is fs supposed to sync data from sdC0 to sdD0? If so, shouldn't
sdD0 have all the partitions of sdC0 at some point?

#2) Later, when I add another 2 drives, I'll want to mirror them and
add them to available storage. What's the easiest way to do this?

#3) Which manpages should I read for info on exporting the storage
pools to other good citizens on my network?

Thanks,

Devon
