I have three drives, with some various partitions, currently set up like
this.
drive0 drive1 drive2
hdb1 hdi1 hdk1
\_________RAID1________/
hdb2 hdi2 hdk2
unused \___RAID0____/
200GB 100GB x 2
hdi3 hdk3
\___unused___/
100GB x 2
What I want to have is 3 x 200 = 400GB RAID5.
I would like to avoid copying 200GB of data to another machine and back
if I can do the conversion. Since mdadm does handle --level= with grow,
I assume I have to create another RAID0 from hd[ik]3, copy the data
there, delete the array using hd[ik]2, create a new RAID5 to use
hd[bik]2, copy the data from the temporary array to the new RAID5 array,
delete the hd[ik]3 partitions, grow the hd[bik]2 partitions, grow the
array, and if I didn't miss a step be done :-(
Is there a better way? Copy over a network or restore are going to be
very slow.
