People.. for the n-teenth time, there are only two ways to kill a troll. One
involves a woodchipper and the possibility of an unwelcome visit from the FBI,
and the other involves ignoring them.

You may want to peek here first. Tim has some scripts already and if not
exactly what you want, I am sure it could be reverse engineered.

Apparently I spent more than my brain wanted me to believe. Here is what I
picked up. Even though I am over the 1 meter limit on SATAII, it worked great.

Last I had heard, there was no solaris support for port multipliers yet, but I
believe that they plan on supporting it in the future. That said, I think that
the FreeBSD port fully supports it now as well as FUSE on Linux. This isn't
really a zfs issue, but more of a driver issue.
The other
Why are we still feeding this troll? Paid trolls deserve no response and there
is no value in continuing this thread. (And no guys, he isn't being paid by
NetApp.. think bigger) The troll will continue to try to downplay features of
zfs and the community will counter...and on and on.

That explains the problems; however, I am able to get them to run by jumpering
them down to SATA1 which brings me back to my original question. Is there a way
to force sata 1 without cracking the drive case and voiding the warranty? I
only have so many expansion slots, so an 8 port supermicro
The drives (6 in total) are external (eSATA) ones, so they have their own
enclosure that I can't open without voiding the warranty... I destroyed one
enclosure trying out ways to get it to work and learned that there was no way
to open them up without wrecking the case :(
I have 2 meter sata
I have a supermicro AOC-SAT2-MV8 and am having some issues getting drives to
work. From what I can tell, my cables are to long to use with SATA2. I got some
drives to work by jumpering them down to sata1, but other drives I can't jumper
without opening the case and voiding the drive warranty.
How are the drives connected? USB or SATA?
Also, is this hardware raid or are you using raidz?
If sata, what controller is being used?

I would personally avoid the P4 chip. They are power hogs and will cost you
more money in the long run than getting a low-end core 2 duo - which should be
faster and not much more money. Make sure you keep power consumption in mind
when you pick up a power supply and video card too. The always
You cannot add 1 drive at a time to a raid-z or raid-2z. You need to add the
same number of disks that were used per stripe.. So, if you start with 5 disks,
you would have to add 5 more in the future to add disk space. There is also a
method of swapping each disk one at a time with a larger
Since no one seems to believe that you can expand a raidz pool, I have attached
the following output from solaris 11/06 showing me doing just that. The first
expanision is with like sized disks, and the second expansion is with larger
disks. I realize that the documentation only has examples
You are definitely hitting a bug.. Not sure which one (hopefully someone else
will chime in on that.) It should take mere milliseconds to destroy a snapshot
regardless of size.
Do you have any disk errors?
What would happen if you scrubbed the pool?

Lets say I reorganized my zpools. Now there are 2
pools:
Pool1:
Production data, combination of binary and text
files. Only few files
change at a time. Average file sizes are around 1MB.
Does it make
sense to take zfs snapshots of the pool? Will the
snapshot consume as
much space as

Also Oracle forums and SUN forums have the SAME exact look and feel... hmmm.
Even the options are exactly the same... weird.
Both are from a company called Jive Software that does enterprise forums.

I am no scripting pro, but I would imagine it would be fairly simple to create
a script and batch it to make symlinks in all subdirectories.

Also note that you may not need new hardware. While not as compatible as linux,
it will run on a variety of hardware, so you may just be able to get by with
new disks.

In other words, say you have 4 - 500 GB drives. In a standard raidz
configuration, you should yield (4-1) * 500 GB of space, or 1.5 TB.
In your case, I will mention one caveat. Say you have 8 drives in raidz. If you
have 7 500 GB and 1 20GB drive, you will only yield (8-1) * 20GB or 140GB of
I get around 100Mbits per second sustained on big files transferring to/from my
Solaris/zfs box and Vista over samba. That is over gigabit ethernet through one
switch and one router. I personally think it should be faster, but is probably
just due to my network hardware and not samba or zfs
I had the same issue with zfs killing my Ultra20. I can confirm that flashing
the BIOS fixed the issue.
