Hi All,
Thanks for all your replies. I understand what I have to do now and
have read several tutorials to get a good grasp of everything.
All your input has been greatly appreciated. Thank you all.
Regards,
James ;)

Thanks for the confirmation though.

good luck.
i built a raid 6 using md as i had 40x1Tb drives to do.
i tried raid 5 with 3 or 4 hot spares but couldn't get it to work like
i wanted.
i think its wise that for every 10 drives, do a hot spare

craig, u can grow via md which is what u do first, then grow the fs.
ex;
mdadm --grow ... to add a drive
then,
mdadm --add ... to gorw the raid onto it
then,
pvresize ... to grow your filesystem onto it.
atleast this is how i've dun it.

md (software raid mechanism or watever u wanna call it) allows u to
grow so if your raid is formatted with an fs that allows u to grow,
then u r good to go (lvm will allow u to grow).
This was also my current belief, again thanks for confirming that.
you will not be able

have you tried your advice cause it sounds like a bunch of theory.
give advice you've actually tried instead of sounding like some
academic.
back it up and build the raid from scratch instead of some theory non
sense.

You have me there.
I've only done perhaps 6 sw based Raids because I would only use hw
Raids for production data, so I sleep better at night.
Tell me, you ever support your Frankenstein contraptions?

I am not sure what h/w raid you are using -
To me, a storage developer and there technique is very different then
using plain old mdadm for sw raids within a Linux distro.
I know vendors like Bluearc, Netapp, etc spin there own firmware, ie
software but thats very very diff then mdadm within the OS.
And yes, i could do for more

Yes, I do not do raid5. That does not mean I have not used mdadm. I do
raid1+0 (not raid10) and I do not see how that disqualifies me from
pointing out that you have the wrong flags for the intended result.
I also do raidz
