Hi experts,
I have a scenario where I need to use a zpool version which is a part of
Nevada currently (snv 125 onwards), but not yet a part of S10.
What is the best way to do it? What all packages do I need to install
from snv in order to upgrade my zpool version?
Thanks in advance,

I would try using hdadm or cfgadm to specifically offline devices out from

I have done that previously with cfgadm for systems I cannot physically access.
You can also use file backed storage to create your raidz and move, delete,
overwrite the files to simulate issues.

We've been reasonably happy with ZFS running on Dell 2970/MD1000 hardware. We

Anyhow, we now have the desire to build pool's even larger - in the 300TB

I lose live redundancy, but can switch the
If the 7310s can meet your performance expectations, they sound much better
than a pair of x4540s. Auto-fail over, SSD performance (although these can be
added to the 4540s), ease of management, and a great front end.
I haven't seen if you can use your backup software with the 7310s, but from

That's what all these appliances (regardless of vendor) get you for
Get the 7310 setup. Vs. the X4540 it is:

We discovered another, more fundamental problem with dedup=fletcher4,verify.
I've just putback the fix for:

Finally, just to be clear, one last point: the two fixes integrated
today only affect you if you've explicitly set dedup=fletcher4,verify.
To quote Matt:
This is not the default dedup setting; pools that only used zfs set
dedup=on (or =sha256, or =verify, or =sha256,verify) are unaffected.
