What about if the pool contains only 1 LUN
In my case, my mirrorring or other data protection mecanism is done
in my storage array so I dont want to setup a mirror on the host side
After the LUN is grown, I go in format -e to autodetect my new device
size and then I write a new EFI label on it us

You'll need twice as much I/O bandwidth as with a hardware controller, plus the
redundancy, since the reconstruction is done by the host. For instance, to

Hello,
So I downloaded this module and integrated it into my samba 3.0.25 source
directory, reconfigured, and did a clean build and install. Problem is, it
doesn't appear that the zfsacl "plugin" was installed anywhere.
Forgive me if this is a newbie question, but how do I get smbd to use that
Hi.
I'm all set for doing performance comparsion between Solaris/ZFS and
FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I
think I'm ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB
RAM, 15 x 74GB-FC-10K accesses via 2x2Gbit FC links. Unfortunately the
links to disks
ZFS will panic during I/O failure if the zpool is not fully redundant.
So you need 2 hba, 2 switches and a RAID10 zpool to keep your server running.
Also upgrade to snv_60 or newer. Older release can corrupt your zpool!

I have a T2000 with an 11/06 release of Solaris 10 installed. I had created a
zpool with one LUN in it. Due to an apparent incompatibility with our HBA's and
switches I unplugged the fibre cables from the server's HBAs. Obviously this is
a dev server ;)
Two days later an admin logs in on the se

HW RAID can offload some I/O bandwidth from the system, but new systems,
like Thumper, should have more than enough bandwidth, so why bother with
HW RAID?

Why bother you say...
I'll asked the Storagetek division this, next time they come round
asking (begging?) me
If you've got the internal system bandwidth to drive all drives then
RAID-Z is definitely superior to HW RAID-5. Same with mirroring.

There's - I mean you can add the same hot spares to different zpools.
