Hi,

I'm looking for advice to not mess up my migration. because
unfortunately i miss drive
I wanna migrate all my data from a raid 5 of 4x2TB (actually 3 because
i'm degraded right now) to a raid 6 of 4x4TB
so exactly i got :
- raid 5, should be 4 disk of 2T but got problem and so right now it's
just 2x2T and a 2Tb disk image in a 4T disk (the raid crashed and is
not start right now but is clean)
- 2 disk of 4TB
- the raid 5 use lvm2 on top of mdadm

I want a raid 6 so i thought i could create a raid 6 degraded with the
2x4TB and after copy the data to this new raid and after add the third
4TB and finally add the 2  2TB as a raid 0 to get a 4TB
I know it's an ideal solution to get 3x4TB + 2x2TB to do my raid but
it give me time to invest.

So my question is :
- is it a really bad idea ?
- do you have a better idea? solution ?
- maybe i can migrate instead of copy a raid to another ?

thank you very much
Math
