Hi!
I feel panic is close...
Short version: I moved the disks of a pool to a new controller without
exporting it first. Then I moved them back to the original controller, but I
still cannot import the pool.
I am new to Opensolaris and ZFS - have set up a box to keep my images and
videos. ASU
Hi all
I've been reading a little, and it seems using WD Green drives isn't very
popular in here. Can someone explain why these are so much worse than others?
Usually I see drives go bad with more or less the same frequency...
Best regards

I am new to OSOL/ZFS myself -- just placed an order for my first system last
week.
However, I have been reading these forums for a while - a lot of the data seems
to be anecdotal, but here is what I have gathered as to why the WD green drives
are not a good fit for a RAIDZ(n) system.

I ordered it. It should be here monday or tuesday. When i get everything
built and installed, i'll report back. I'm very excited. I am not
expecting problems now that i've talked to supermicro about it. Solaris 10
runs for them so i would imagine opensolaris should be fine too.

(3) Was more about the size than the Green vs. Black issue. This is all
assuming most people are looking at green drives for the cost benefits
associated with their large sizes. You are correct Green and Black would most
likely have the same number of platters per size.

I just tried as well on osol134. I have the Western Digital Caviar black
drives that still support tler (the older ones). Same result: no changes
occur. This is on a 3420 ibex peak chipset

1. even though they're 5900, not 7200, benchmarks I've seen show they are quite
good
3. what is TLER?
4. I thought most partitions were aligned at 4k these days?
We don't need too much speed on this system, we're still limited to 1Gbps
ethernet, and it's mostly archive data, no reads exceedin

They have a 64 MB cache onboard, which hides some of their slowness. But
they are slow.

I believe that was what you were missing from your command. However I did not
try to change controller.
Hopefully you only been unplug disks while the system is turn off. If that's

Hello,
I'm a grown-up and willing to read, but I can't find where to read. Please
point me to the place that explains how I can diagnose this situation: adding a
mirror to a disk fills the mirror with an apparent rate of 500k per second.
1) what diagnostic information should I look at (and per

I guess it was tl;dr the first time I said this, but:
the old theory was that a USB device does not get a devid because it

I'm pretty sure you can't have compression or dedup enabled on a dump volume.
