I've read the Handbook sections on gmirror and gjournal, and the
gjournal-desktop article, and I'm still unclear on how to go about
setting up a configuration that uses both.
* Since I haven't started the installation -- thus the partitions
haven't even been created yet -- it seems as if it "should" be
possible to put the journals in the same partitions with the data.
* Since I can't mirror or journal a FAT32 slice AFAIK, and there
seems little point in mirroring swap or /tmp, I think I want to
end up with something along the lines of (on identical drives ad0
and ad2):
ad0 ad2
ad0s1 FAT32
ad0s2 FreeBSD ad2s1 FreeBSD
ad0s2a <----- gm0 -----> ad2s1a
|
+-----------------+
|
| ad0s2b swap ad2s1b swap
| ad0s2c [whole slice] ad2s1c [whole slice]
| ad2s1d /tmp [same size as ad0s1]
v
gm0
gm0s1
gm0s1a
gm0s1a.journal [gjournal label ad0s1a ad0s1a] rootFS
gm0s1c [whole mirror]
gm0s1d
gm0s1d.journal [gjournal label ad0s1a ad0s1a] /var
gm0s1e
gm0s1e.journal [gjournal label ad0s1a ad0s1a] /usr
How do I go about doing something like this?
