This is basically the setup I suggested a year or so ago. While the theory is
sound, the major problem with it is that iSCSI and ZFS are not a great
combination when a device (in your case server) goes down. If you create a
pool of several iSCSI devices, when any one fails, the entire pool wil
Hi,
Does anyone know since when hybrid pools are available in ZFS? Are there
ZFS "versions"?
XVM Server is based on Nevada b93, and I need to know if it supports
hybrid pools.
TIA, Rafael.

That card does work well, and uses the same chipset as the Thumper. I've found
that there are some issues with hot swap, but other than that it works fine.
I've got one in a live ZFS server right now.

That is very interesting. What kind of hardware did you use? Do you have any
statistics about throughput and I/O behavior? Maybe you could provide the
detailed architecture. Unfortunately I did not find your e-mail address in your
user profile for direct contact.

Bob, thank you very much for your detailed answer. Indeed, Resilvering could be
a very difficult situation in such a big storage pool. I could solve this issue
by building a pool for each backend node. But then I run into the same problems
I have at this moment: The disk space of my server is he
Dave, what kind of hardware did you used? I am scared about the bandwith and
I/O throughput of the zfs gateway.

I don't have any statistics myself, but if you search the forum for iscsi,
there was a long thread a few months back with some performance figures. I
didn't really do that much testing myself, once I hit the iscsi bug there
wasn't any point doing much more.
There has been some work on that rec

Thanks everyone for your answers.
I am ashamed to say that I have become lax in reading documentation
due to the high quality of the forums. Of course, my question was
easily answered both by reading docs and quick responses.
I rarely see anyone telling a questioner to RTFM anymore since th
You might want to look into the products from a company called
DataCore Software, http://datacore.com/products/prod_home.asp. I've
used them and they are great stuff. They make very high performing
iSCSI and FC storage controllers out of leveraging commodity hardware,

Hi,
I have been doing some basic performance tests, and I am getting a big hit
when I run UFS over a zvol, instead of directly using zfs. Any hints or
explanations is very welcome. Here's the scenario. The machine has 30G RAM,
and two IDE disks attached. The disks have 2 fdisk partitons (c4d0p2,

I have a ZFS pool that has been corrupted. The pool contains a single device
which was actually a file on UFS. The machine was accidentally halted and now
the pool is corrupt. There are (of course) no backups and I've been asked to
recover the pool. The system panics when trying to do anything w
Is there a documentation available for zfs source code?
