1st thx for the quick response.
Current config is windows XP with 8 seprate non raided 1.5TB sata NTFS drives
That doesn't look hopeful whats more I would hightly recommend *against*
running ZFS without either mirroring or raidz.
Are these drives all actually full or can you use some windows software
to shrink the NTFS filesystem ? If so how small could you get it ?
So is it 8 separate NTFS filesystems ? If not there is some kind of
raid, it might be a concat or a stripe. From what you have said it
sounds like it isn't a mirror or raid 5.
A mirror would have been ideal because you could break the mirror,
create a new ZFS pool out of the mirror and copy the data over to that,
then destroy the NTFS filesystem and add the drives to the ZFS pool as
mirrors. However it doesn't sound like you have the config able to do
that.
My backup data is stored on another server with hardware raid 5 and FreeNas
this wont come into the equation.
I currently dont have a opensolaris install. The current does and donts of the
storage pool system are still unclear to me as I am RTFMing.
I do have a sata intel hardware raid controller that I have not installed on any of my systems yet. So what I would like to do is create a new server potentially booting it from a CF drive. And have the sata drives running as redundant storage space.
Use of hardware raid to providing mirroring, striping or raid5 is
generally not recommended with ZFS.
The crux being that I dont want to loose all the data that is currently on the
drives during transformation.
I hope this is clearer and thx.
It is but I don't think you can easily do it given the hardware and raid
configuration you have.
Note also that by default OpenSolaris can't actually read NTFS but with
FUSE it can http://opensolaris.org/os/project/fuse/ The FUSE project
has not yet integrated into OpenSolaris so it is not in the repository.
