Pedantically, because ZFS does 128kByte I/Os. Setting maxphys >

I know, but with the default maxphys value of 56kByte on x86 a 128kByte

But I don't think size matters on this problem, since you can already see
during the catalog creation phase that UFS is 2x faster.

Hi,
I'm preparing a personal TPC-H benchmark. The goal is not to measure or
optimize the database performance, but to compare ZFS to UFS in similar
configurations.
At the moment I'm preparing the tests at home. The test setup is as
follows:

. 2 x AMD Opteron
Solaris 10 update 1 (1/06 release) supports SCSI disks larger than 2 TB. I
believe that the same is true for IDE (as long as your controller supports
48-bit LBA).
The initial release of Solaris 10 has a 2 TB limit for 64-bit kernels, 1 TB for
32-bit kernels (or so the documentation claims, tho

I've been playing with offlining an external USB disk as a way of having a
backup of a laptop drive. However when I online the device and scrub it I
always get cksum errors.
So I just build a v880 in the lab with a mirrored zpool. I offlined 2 disks
that form the mirror and then created a new f

Hello All,
Attached is a conversation I've had with an old friend / colleague /
sysadmin (cc'ed) and it raises three questions for me.
I would like to ask the panel, from the context as described below:
Did Sol9 have a 1Tb limit on addressing IDE
Does S10?
Would ZFS

I studied Computing Science at Glasgow University (Scotland) the
department policy was NOT to use disk quotas. This was on SunOS 4.
