Hello list,
My ZFS pool has found it's way into a bad state after a period of
neglect and now I'm having trouble recovering. The pool is a three-way
mirror of which 2 disks started showing errors and thus the pool
was degraded.
I shut down the system and started at the lowest level by using ES
Actually, my ideal setup would be:
Shuttle XPC w/ 2x PCI-e x8 or x16 lanes
2x PCI-e eSATA cards (each with 4 eSATA port multiplier ports)
Mike, may I ask which eSATA controllers you used? I searched the Solaris HCL
and found very few listed there
Thanks

I didn't use any.
That would be my -ideal- setup :)
I waited and waited, and still no eSATA/Port Multiplier support out there, or
isn't stable enough. So I scrapped it.

I agree with mike503. If you create the awareness (of the instability of
recorded information) there is a large potential market waiting for a ZFS/NAS
little server!
Very nice the thin client idea. It will be good to also use the NAS server as a
full server and use remotely with a very thin

I'd like to extend my ZFS root pool by adding the old swap and root slice
left over from the previous LU BE.
Are there any known issues with concatenating slices from the same drive?
Having done this in the past (many builds ago) I found the performance
wasn't good.
A little more information today. I had a feeling that ZFS would continue quite
some time before giving an error, and today I've shown that you can carry on
working with the filesystem for at least half an hour with the disk removed.
I suspect on a system with little load you could carry on

It sounds like your good disk has some serious problems and that
formatting the two disks with bad sectors was the wrong thing to do.
You might have been able to recover using the two

Mark,
Thanks for your detailed review comments. I will check where the latest
man pages are online and get back to you.
In the meantime, I can file the bugs to get these issues fixed on your
behalf.
Thanks again,
Cindy

I just read about this new NAS product based on OpenSolaris and ZFS. There are
lots of questions on this forum about good hardware for a home NAS box so the
hardware/software this company is using might be interesting. From their site,
they are using a 1.5 Ghz Low Voltage VIA C7 processor with
I think the important point here is that this makes the case for ZFS
handling at least one layer of redundancy. If the disk you pulled was
part of a mirror or raidz, there wouldn't be data loss when your system
was rebooted. In fact, the zpool status commands would likely keep
working, and
Just a side comment: this discussion shows all the classic symptoms of
two groups of people with different basic assumptions, each wondering why
the other said what they did.

Hi guys,
we are proposing a customer a couple of X4500 (24 Tb) used as NAS

Both server will contain the same files and should be accessed by
different clients at the same time (i.e. they should be both active)

Obviously, I should stop answering, as all I deal with and all that I will
deal with is GA Solaris. OpenSolaris might as well not exist as far as I'm
concerned. With that in mind, I'll just keep reading and appreciating all of
the good zfs info that comes along.
Peace out.
