I'm likely to be building a ZFS server to act as NFS shared storage for a
couple of VMware ESX servers. Does anybody have experience of using ZFS with
VMware like this, and can anybody confirm the best zpool configuration?
The server will have 16x 500GB SATA drives, with dual Opteron CPU's and
the procedure is follows:
1. mkdir /tank
2. touch /tank/a
3. zpool create tank c0d0p3
this command give the following error message:
cannot mount '/tank': directory is not empty;
4. reboot.
then the os can only be login in from console. does it a bug?

Hy Peter and all,
after a couple of reboot the PowerPath and reconfiguring the LUN
exported by the Clariion now all seems to working fine.
Following the output of zpool status:

Thanks to Brandon High [EMAIL PROTECTED] and I am sorry for my thickness
and having an assumption I could not export a faulted pool. After
failure, I exported then imported with zpool cmd and it came back.
Thanks!

did you end up purchasing this ? We're considering buying a SilMech K501
as our new fileserver with a pair of Areca controllers in JBOD mode. Any

We are currently using the 2-port Areca card SilMech offers for boot, and 2 of
the Supermicro/Marvell cards for our array. Silicon Mechanics gave us great
support and burn-in testing for Solaris 10. Talk to a sales rep there and I
don't think you will be disappointed.

Yes, always an excellent recommendation.
Note that there are some companies, Crucial and STEC come to mind,
sell SSDs which fit in disk form factors. IIRC, Mac Book Air and EMC

Hi all ;
There are two tinhs that some customers are asking for constantly about ZFS.
Active active clustering support.

a proxy kind of set up ? ]
Any hope for these features?

Unfortunately, we need to be careful here with our terminology.
SSD used to refer strictly to standard DRAM backed with a battery (and,
maybe some sort of a fancy enclosure with a hard drive to write all DRAM

Hi,
there is mirrored pool in i86 system with Solaris 10. The one disc is
internal SATA via PCI link, another USB mobile disc. OS does not boot
when USB is plugged on. It is necessary to take it off, then system
boots, then plug it on and then work OK.
What a hell is that?
Regards,
Re-reading your question is occurs to me that you might be referring
to the ability to mount a snapshot on *another server* ?
There's no built-in feature in zfs for that, but a workaround would be
to do what I just detailed, with the additional step of exporting that
cloned snapshot to the

Snapshots are available through .zfs/snapshot/snapshot-name.
Snapshots are read-only. They can be cloned to create read-write

Agreed -- inserting the USB drive can sometimes cause the controller
targets to shift (for example, the boot device might now be c1d0 instead
of c0d0) -- that will cause problems...
