Hi: (Warning, new zfs user question)
I am setting up an X4500 for our small engineering site file server.
It's mostly for builds, images, doc archives, certain workspace
archives, misc
data.
...
Can someone provide an actual example of how the config should look?
If I save two disks for the boot, how do the other 46 disks get configured
between spares and zfs groups?
What I ended up with was working with 8+2 raidz2 vdevs. It could have been
4+2, but 8+2 gives you more space, and that was more important than
performance. (The performance of the 8+2 is easily adequate for our needs.)
And with 46 drives to play with I can have 4 lots of that. At the moment I
have
6 hot-spares (I may take some of those out later, but at the moment I don't
need them).
So the config looks like:
zpool create images \
raidz2 c{0,1,4,6,7}t0d0 c{1,4,5,6,7}t1d0 \
raidz2 c{0,4,5,6,7}t2d0 c{0,1,5,6,7}t3d0 \
raidz2 c{0,1,4,6,7}t4d0 c{0,1,4,6,7}t5d0 \
raidz2 c{0,1,4,5,7}t6d0 c{0,1,4,5,6}t7d0 \
spare c0t1d0 c1t2d0 c4t3d0 c5t5d0 c6t6d0 c7t7d0
this spreads everything across all the controllers, and with no more than 2
disks on each controller I could survive the rather unlikely event of a
controller failure (unless it's the controller with the boot drives...).
