Bonjour,
I just rebuilt my home ZFS server using openindiana (formerly Solaris
Xpress 11) and napp-it, an configured it for Windows or Android
clients. The boot pool (rpool) was built by OI's installer; the storage
pool (tank, 9GB) was created by napp-it's "create pool" function, using
the ashift=12 parameter (6 x WDEARS 1.5Tb disks in RAIDZ2 configuration).
So far, everything works, as a couple of thorough tests have shown, and
I have restored the whole server from a backup machine I built. Napp-it
"dd" benchmarks reports nice figures, 125.02 MB/s Write and 323.88 MB/s
Read.
However, I have noticed that the pool status report (below) contains a
suggestion to upgrade the pool, which is currently v28, which surprises
me. Before proceeding, I would like to obtain informed opinions on the
matter, including risks on the whole setup, if any.
Many thanks for any help,
Robert.
Below is the information obtained from napp-it:
My pools:
Root Pool (ashift = 9):
rpool 5000 16454639525011445801 vdevs: 1
vdev 1: mirror 9 500.07 GB
Storage pool (ashift = 12, obtained through napp-it "Create Pool" command):
tank 28 4308072134310677912 vdevs: 1
vdev 1: raidz2 12 9.00 TB
zpool status (obtained from napp-it->jobs->scrub->pool status):
