This configuration doesn't make a lot of sense for redundancy, since
it doesn't provide any. It will have poor performance caused b
Hello, I'm going to build home server. System is deployed on 8 GB USB flash
drive. I have two identical 2 TB HDD and 250 GB one. Could you please recommend
me ZFS configuration for the set of my hard drives?
1)
pool1: mirror 2tb x 2
pool2: 250 gb (or maybe add this drive to pool1???)
2)
pool1: mi
You can also make 250 GB slices (partitions) and create RAIDZ 3x250GB and
mirror 2x1750GB (one or more).
Mirror has better performance for write operations, Raidz shoud be faster for
read.

With two drives it makes more sense to use a mirror then raidz configuration.
You will have the same amount of space and mirroring gives you more
performance, afaik.

As Cindy said, skip dedup for now. It's not stable (enough). Try to destroy

I kicked off a scrub just to see, and we're scrubbing at 200MB/s (2
vdevs) and the CPU is 94% idle, 6% kernel, 0% IOWAIT.
zpool-tank is using 3.2% CPU as shown by 'ps aux | grep tank'
Whoops..

Craig,
I'm sure the other home file server users will comment on your gear
and any possible benefit of a L2ARC or separate log device...
Use the default checksum which is fletcher4, I fixed the tuning guide
reference, skip dedup for now. Keep things as simple as possible.
Thanks,

I am working on a home file server. After reading a wide range of blogs and
forums, I have a few questions that are still not clear to me
1. Is there a benefit in having quad core CPU (e.g. Athlon II X4 vs X2)? All
of the web blogs seem to suggest using lower-wattage dual core CPUs. But;
