> There are no section on converting an existing partition to RAID.
I created the tool that enable to convert the datas from nearly any
configuration to any other one (RAID1 -> RAID5, RAID5 to RAID5 with
more disks, ...) and I announced it, but it seems that the RAID
team does not like it, since they did not even mentionned it in the
HOWTO (what I also reminded to the HOWTO maintener a few weeks ago,
but I did not receive even an answer).
The key issue is that it's written in Pliant, not in C.
Also it's released on GPL v2, so if they don't like it in Pliant,
they can convert it to C. What my script demonstrate is that
reconfiguring is not that hard (less than 500 lines of code
including all the checkup parts).
It seems to me that the RAID 0.90 tool is great (I use it on my
production server and found it to be even more reliable than
the hardware RAID in my configuration) on it's kernel part
(Ingo seems to be a very clever hacker), but Linux seems to have
entered a dark period where IPOs are interfering with purely
technical issues, so now, the kernel code still gets better and
better, but the all thing gets rather closed so rather slow,
since some (hopefully not all) area leaders will spend more time
keeping away any new potencial chalenger. Shakespeare will soon
apply also in Linux world since Linux hackers are men.
Anyway, the Pliant script for converting RAID sets is at:
http://pliant.cx/pliant/linux/storage/raid.pli
and the Pliant site is at:
