Re: Converting Boot/System Disk to Dynamic Disk

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Even using SCSI320 I've seen where a softraid pair (RAID1) rebuilds on every
restart. I believe this is due to excessive IO during shutdown and may be
more prominent on SBS due to it's many functions all shutting down together.
I believe the system doesn't set the 'array in sync' during shutdown.

I've seen the behaviour on decent hardware (Xeon 2.x, possibly dual, 2GB
RAM) being a test system and therefore not heavily loaded.

I do however consider softraid preferable to those useless onboard SATA RAID
systems that have no error logs, very minimal management functions, no
alarm, no provision for hotspare, which generally also borrow CPU cycles and
are in fact hybrid soft/hard/driver systems.

Hi Gregg:

Can you provide some documentation as to why the OP, and presumably
others,
should avoid software RAID? I have found it to very reliable and easier
to
manage than many of the on-board "RAID" controllers that will not allow
one
to add a drive after the OS is installed, or that lose the RAID settings
if
both of the drives are removed and force one to begin again.

If anyone knows of a source for info regarding manageable on-board
controllers, that would be a great resource.

I wholeheartedly agree that the "best" RAID controllers are discrete
add-on
cards, but for some they are fairly pricey.

It is safe and is required if you will be using software RAID, which
brings
me to my next comment. AVOID software RAID. Buy a hardware RAID
controller
instead.

I have a SBS2003 installation with two HDD's. Disk 0 has two
partitions -
one partition contains the boot/system files and the second partition
contains data. I want to use the second disk to create a software
mirror
of
the data partition on disk 0.

When SBS2003 installed, it created disk 0 as a "basic" disk and I know
it
needs to be a dynamic disk before I can mirror it. I see that I an
option
exists to convert diski 0 to dynamic.

My question and concern is that will the system still boot fine and
will
that partition be undisturbed when I've finished the dynamic
conversion.
I
checked the conversion steps and there seems to be a lot of warnings
concerning converting the boot/system disk.

Any help/guidance would be appreciated.
