How is the quality of the ZFS Linux port today? Is it comparable to Illumos
or at least FreeBSD ? Can I trust production data to it ?

Is anyone even using ZFS under Xen in production in some form. If so, what's
your impression of reliability ?

The good news is that ZFS is getting popular enough on consumer-grade
hardware. The bad news is that said hardware has a different set of
failure modes, so it takes a bit of work to become resilient to them.
This is pretty high on my short list.
So does this basically mean zfs rolls-back
Unmount is not sufficient.
Well, umount is not the right way to do it, so he'd be simulating a
power-loss/system-crash. That still doesn't explain why massive data loss
would occur ? I would understand the last txg being lost, but 90% according
to OP ?!
Did anyone share a script to send/recv zfs filesystems tree in
parallel, especially if a cap on concurrency can be specified?
Richard, how fast were you taking those snapshots, how fast were the
syncs over the network. For example, assuming a snapshot every 10mins,
is it reasonable to expect to

The setup is not there anymore, however, I will share as much details

I will probably be testing again soon. Any

You might want to look at AVS for realtime replication

However, I have had huge performance hits after enabling that. The

Hi,
I have setup AVS replication between two zvols on two opensolaris-2008.11
nodes. I have been seeing BIG performance issues, so I tried to setup the
system to be as fast as possible using a couple of tricks. The detailed
setup and performance data are below:
* A 100G zvol has been setup
Well, I checked and it is 8k
volblocksize 8K
Any other suggestions how to begin to debug such issue ?

Not sure if this is the best place to ask, but do Sun's new Amber road

Unfortunately, every now and then someone has his zpool corrupt, with no

I suggest translating the reliability problems into a cost for

Intel mainstream (and indeed many tech companies') stuff is purposely
stratified from the enterprise stuff by cutting out features like ECC and
higher memory capacity and using different interface form factors.

Well, if you can probably afford more SATA drives for the purchase
price, you can put them in a striped-mirror set up, and that may help
things. If your disks are cheap you can afford to buy more of them
(space, heat, and power not withstanding).
Hmm, that's actually cool !

I observe that there are no disk vendors supplying SATA disks
with speed 7,200 rpm. It is no wonder that a 10k rpm disk
outperforms a 7,200 rpm disk for random workloads. I'll attribute
this to intentional market segmentation by the industry rather than
a deficiency in the transfer
So, performance aside, does SAS have other benefits ? Data integrity ? How
would a 8 raid1 sata compare vs another 8 smaller SAS disks in raidz(2) ?
Like apples and pomegranates. Both should be able to saturate a GbE link.
You're the expert, but isn't the 100M/s for streaming not random
performance), and offers better performance and
MTTDL than 8 sata raidz2, I guess I will go with 8-sata-raid1 then!
Hope I'm not horribly mistaken :)
